# 开发约定
- 框架保持通用,不内置接入项目的业务类型、字段、错误码或业务规则。
- 2026-09-25 用户要求:每次功能开发完成,必须同步维护根 README.md。README 需要覆盖当前全部公开功能,解释用途、基本用法,并提供可运行示例或链接到 examples 内的完整示例。
- 新增、调整和删除功能都必须同步文档、示例、测试与发布说明。删除功能要明确说明已移除内容、影响范围和迁移步骤,不能继续把历史用法当作当前能力推荐。
- examples 使用通用场景,避免依赖业务项目、私有数据库或线上服务。必要的外部基础设施配置应明确说明。
- 2026-09-25 用户决定:移除 mappings/mappingFiles 及结构映射代码生成机制,改用可选 copyx 工具包。不得恢复另一套 JSON 或 Go 映射声明语言。
- 深拷贝的自定义转换结果不得与输入共享可变引用;发现共享应报错,不能降级成浅拷贝或静默接受。

# 通用业务开发能力完善计划
本轮目标:业务维护契约、配置、依赖装配与业务逻辑,框架持续维护 HTTP 接入、契约校验、通用运行期与文档。按实际生成项目和可删除的业务适配点验收,不写入 eTax 业务规则。
## 实施与验收清单
- [x] 运行期:资源登记、逆序释放、幂等关闭、失败回滚、故障原因保留归框架;生成入口与项目依赖初始化边界明确。多 App 日志隔离、标准 log.Logger 适配、可信请求元数据与依赖中间件示例。
- [x] 配置:项目完整结构体环境覆盖;默认值→文件→环境;嵌套、duration、slice、显式零值、空值策略、必填与脱敏;日志无副作用完整校验。
- [x] 数据库:官方 MySQL 结构化配置/TLS/驱动日志适配,继续复用 OpenConnector 和唯一连接池;独立启动检查、失败清理、生成器接入;不内置版本/表结构/业务错误策略。
- [x] 响应契约:数组、可空对象、成功 null、独立 HTTP 204;Logic/Handler/OpenAPI/漂移检查一致。
- [x] 请求契约:未知 query、JSON UTF-8/charset、无 Body/必填空对象/可选 Body,App 默认与路由覆盖;scalar/any/数组/大小限制一致,普通 JSON 只绑定一次。
- [x] 上传:声明文件/文本/JSON 字段,重复/未知/必填/单字段/单文件/总量限制;有界暂存与清理,调用 Logic 前完成普通表单校验;保留流式扩展与 Complete 约定。
- [x] 文档工具:字段注释、example/枚举描述进入 DTO 与 OpenAPI;保注释、幂等格式化及 check;显式 Go 错误目录元数据导出与文档合并,不自动执行项目代码。
- [x] 共享契约:受控 roots/摘要、循环/深度/文件数/路径保护;分源文件 DTO、多个独立 module 的工作区检查;版本提示与基础模板升级预览,保留业务文件。
- [x] 集成:实际生成项目验证新能力、连续生成、业务文件保留、失败清理、nethttp/native 请求与退出;现有错误继承/参数/上传下载回归。
- [x] 最终回归:全量 race(含生成器集成)、vet、build、格式化/链接检查;使用说明、迁移步骤及验收报告完整,发布后远程无 replace 验收。
已发布 `v0.14.0-preview`。逐项验收、可替换的业务适配点与远程报告见 [验收记录](reports/businessDevelopmentAcceptance.md);接入和升级见 [开发指南](DEVELOPMENT.md)。
## 核心约定
响应与错误码由项目配置。字段与请求策略由契约表达;基础设施采用可选适配器,保留标准 Connector。所有业务依赖在请求排空后关闭;框架不重试写操作、不自动迁移业务表、不关闭借用资源。
普通 multipart 为保证进入 Logic 前完成校验,以有界复制暂存到临时文件;框架清理自己创建的资源。纯流式路径明确由调用方在提交持久副作用前完成输入检查。
不修改 eTax/ePay 业务,不连接既有业务服务器。真实基础设施如需验证,只使用本轮隔离资源。验收报告明确区分单元测试、生成消费者测试与真实服务测试。

# 统一配置加载
v0.20 起,新生成服务的 `main.go` 调用生成器维护的 `config.Load`。项目只需要定义业务字段、默认值和校验;日志、HTTP、数据库等配置使用同一流程,配置加载时不打开数据库、监听端口或创建日志文件。
```text
代码默认值 → envDefault(仅填零值)→ 可选配置文件
→ 完整结构体环境覆盖(含别名)→ 框架规范化 → 项目 Validate
→ 初始化日志及项目依赖 → 启动服务
```
## 生成项目要维护什么
| 文件 | 维护方 | 用途 |
| --- | --- | --- |
| `main.go` | 生成器 | 启动、信号、请求排空、依赖关闭 |
| `internal/config/loadGen.go` | 生成器 | 调用统一加载入口;纳入 `generate --check` |
| `internal/config/config.go` | 项目 | `Config`、`Default()`、`Validate()` |
| `internal/config/loader.go` | 项目 | `NewLoader()`,只有增加文件格式时才需修改 |
| `etc/config.yaml` | 项目 | 部署配置;可改用 JSON/XML 并传 `-config` |
| `internal/svc` | 项目与生成器分文件 | 初始化依赖、登记清理、AppOptions |
比如增加业务的批次数量:在 Config 增加一个字段,在 Validate 加范围校验;需要部署值时改配置文件或环境变量。不修改 main、Load 或 Handler。
```go
// 添加到项目 Config。
BatchSize int `json:"batchSize" envDefault:"100"`
// 添加到项目 Validate。
if c.BatchSize < 1 || c.BatchSize > 1000 {
return omniConfig.Invalid("batchSize", "must be between 1 and 1000")
}
```
自动支持 `GO_OMNI_BATCH_SIZE`。生成服务的空环境值策略为 `ignore`,0 和 false 是有效覆盖;范围由 Validate 决定。
重新生成保留 config.go、loader.go 和 svc 的手写扩展。
## 手写项目用法
```go
package main
import (
"time"
"git.yuntuo.hk/k2safe/go-omni/config"
)
type Config struct {
Timeout time.Duration `json:"timeout" envDefault:"3s"`
Limit int `json:"limit" envDefault:"100"`
Token string `json:"-" env:"APP_TOKEN,secret"`
}
func (c Config) Validate() error {
if c.Timeout <= 0 {
return config.Invalid("timeout", "must be positive")
}
return nil
}
// cfg, err := config.LoadProject("etc/config.yaml", Config{},
// config.EnvOptions{Prefix: "APP_", Empty: "reject"})
```
`LoadProject` 接收结构体默认值,可实现值接收器或指针接收器的 `Validate() error`。空路径表示不读文件。
`DecodeFile` 只做文件覆盖,不做 envDefault、环境覆盖或业务 Validate;旧的两参数调用仍有效,可用结构体或结构体指针。低层 `ApplyDefaults`、`OverlayEnv`、`LoadFile` 继续存在。
嵌套校验用 `config.AtField("client", err)` 加路径前缀。公共原因通过 `config.Invalid` 提供,原因中不要包含密码、DSN、Token 或输入原值。
## JSON / YAML / XML
按文件扩展名选择解析器:`.json`、`.yaml`、`.yml`、`.xml`,大小写不敏感。所有格式使用 Go 结构体的 **json 字段名**,无需为 XML 复制一份结构或标签。
以下配置等价:
```json
{"client":{"timeout":"2s"},"enabled":false,"ports":[8080,8081],"optional":null}
```
```yaml
client:
timeout: 2s
enabled: false
ports: [8080, 8081]
optional: null
```
```xml
<config>
<client><timeout>2s</timeout></client>
<enabled>false</enabled>
<ports type="array"><item>8080</item><item>8081</item></ports>
<optional type="null"/>
</config>
```
XML 必须使用一个 `<config>` 根;普通叶节点按目标 Go 类型转换。数组显式 `type="array"` 加 `<item>`,不根据重复元素猜测类型。`type="array"` 空元素表示空数组,`type="object"` 表示空对象,`type="null"` 表示 null。`any` 中的 XML 叶节点默认是字符串,需要动态数字/布尔时标注 `type="number"` / `type="bool"`;也可用 `type="string"`。
类型和覆盖规则:
- 缺失字段保留默认值;显式 0、false、空字符串正常覆盖。
- null 清空指针、map、slice、interface;普通值字段保持默认值,沿用 Go JSON 解码语义。需要区分 null 时用指针。
- 数组整体替换;空 slice 保持非 nil;固定长度 Go 数组要求长度一致,避免丢弃多余配置。
- map 合并键,已提供的键整体覆盖对应值;map 中未提供的键保留。
- duration 支持 `250ms`、`3s`;整数保持精度,动态 JSON 数字使用 `json.Number`,不先转 float64。
- 自定义 `json.Unmarshaler` / `encoding.TextUnmarshaler` 仍可接入。这些回调是可信项目代码,必须自己保证并发和副作用安全;不要修改共享外部状态。
- JSON `,string` 字段、嵌入字段遵循 JSON 字段选择;未知字段、重复绑定、冲突均拒绝。
内置解析器限制:单文件最多 1 MiB,解析最多 64 层、100000 个节点;绑定和默认值复制也有深度限制。只接受普通文件,不读取设备或命名管道。不支持多文档、重复字段、无效 UTF-8;YAML 拒绝 alias/merge/custom tag,XML 拒绝 DTD/外部实体、命名空间、业务属性和混合内容。XML 仅支持配置所需的子集,不是通用 XML 文档映射器。
这些限制针对启动配置,避免意外超大文件、别名扩展和模糊覆盖。自定义值解码器的内部字段校验由该解码器负责;例如现有错误目录使用其专有解码规则。
## 环境覆盖
统一入口的 EnvOptions 控制前缀、空值策略、别名和 Lookup。完整 JSON 路径自动转换为 UPPER_SNAKE_CASE:`client.timeout` → `APP_CLIENT_TIMEOUT`。
```go
config.EnvOptions{
Prefix: "GO_OMNI_", Empty: "ignore",
Aliases: config.ServerEnvAliases("GO_OMNI_", "server"),
}
```
生成项目同时接受完整的 `GO_OMNI_SERVER_HTTP_READ_TIMEOUT` 与短别名 `GO_OMNI_HTTP_READ_TIMEOUT`。完整名存在时优先,即便其空值被 ignore,也不回退别名。不会再二次调用 ApplyEnv 覆盖业务字段。
显式 `env:"CUSTOM_NAME"` 是绝对名称;`env:"-"` 跳过子树。`json:"-"` 只在声明显式 env 名时参与,可让密钥只能从环境加载。`secret` 标签表达用途,解析错误对所有字段都不打印值。slice/map 的环境值采用 JSON。`required` 检查字符串非空、指针/集合非 nil;复杂范围由 Validate 负责。详见 [完整业务环境覆盖](DEVELOPMENT.md#完整业务配置的环境覆盖)。
显式环境选择日志 stdout/stderr 会清除文件 profile 的 File/Rotation,除非同时提供非空 File 覆盖。该兼容规则由框架处理。
## 扩展解析器
内置格式直接可用。新增格式只在 `internal/config/loader.go` 的 `NewLoader` 注册:
```go
func NewLoader() (*omniConfig.Loader, error) {
return omniConfig.NewLoader(
omniConfig.WithDecoder("custom", omniConfig.DecoderFunc(
func(data []byte) (omniConfig.Document, error) {
// 演示注册扩展名;实际可在这里调用项目选定的 TOML 等解析库。
return (omniConfig.JSONDecoder{}).Decode(data)
},
)),
)
}
```
Decoder 返回 Document:Value 是 map[string]any 根,子值为 string/bool/json.Number/nil/[]any/map[string]any;无自身类型的叶节点可返回 config.Text。Positions 可选,用 `client.timeout` 或 `servers[0].timeout` 标记 1-based 行列。不提供位置时仍有文件、字段、原因。
自己的语法错误可返回 `&config.Error{Field: "client.timeout", Line: 3, Column: 5, Reason: "expected a duration"}`。Reason 必须安全;普通第三方错误仅公开 `invalid configuration syntax`,内部 cause 通过 errors.Is/As 保留。
注册表属于 Loader 实例,无全局 init 注册;不能覆盖已有扩展名。Loader 可共享,但 Decoder 必须支持并发且不保留/修改输入。解析插件是可信 Go 代码,框架不是插件沙箱。新格式依赖由选择它的项目显式引入,核心不强制引入 TOML 等库。
## 定位配置错误
```text
config "etc/config.yaml":4:12 field "client.timeout": expected a duration such as 5s
config env "APP_CLIENT_TIMEOUT" field "client.timeout": expected a valid time.Duration
```
`errors.As(err, &diagnostic)` 可获取 `*config.Error` 的 File/Field/Env/Line/Column/Reason;原 `DecodeError` 名称保留为别名。`errors.Is` 可判断文件不存在等 I/O 原因。
解析失败显示文件和可获取的行列;Validate 使用 Invalid/AtField 才能定位业务字段。环境覆盖导致的错误优先标环境变量,不错误地归因到文件;数组元素验证也会追溯到覆盖它的集合环境变量。默认值未出现在文件里时没有行列。YAML 语法错误通常只有行号,列显示 1。
不打印底层错误原文或配置值;任意普通 `errors.New(...)` 校验失败的公开原因是 `validation failed`,内部原因仍在链中。项目应改用 Invalid 给出安全的原因。第三方子配置校验若没有字段元数据,只定位到对应子树,框架不会从任意错误文案猜字段。
不要把 Unwrap 后的原始错误、整个配置对象写入公开日志/HTTP;自定义解析器与校验器传入的 Reason 由项目负责脱敏。
## v0.19 及更早项目迁移
先提交现有代码,再升级匹配的 CLI 与框架。旧项目的 `internal/config/config.go` 含手写 Load,新生成器会明确阻止 generate/check/dry-run,不会直接覆盖它。
1. 保留 Config、Default、Validate、业务配置结构及辅助函数。
2. 删除旧 Load。普通的 defaults/file/env/Validate 流程已由 LoadProject 接管;移除由此不再使用的 import。将自定义默认值和校验分别迁入 Default / Validate,自定义文件格式迁入 NewLoader。
3. 框架只在 `loader.go` 不存在时创建 NewLoader;已有项目文件同名时需要保证它提供同签名函数。无需手写 loadGen.go。
4. 重新生成,执行 `generate --check`、`go test ./...`、`go build .`,再用真实配置验证启动。
保留业务需要的显式 env 标签/规则;如果原 Load 有解密或其他项目特殊步骤,不要直接删除,应先明确其归属,必要时在自定义 Decoder 中处理。生成器不自动搬动或猜测手写行为。`api upgrade` 仍可预览较早版本的基础设施差异,但已修改的配置必须按上述步骤迁移。
不会移除低层配置 API;本次移除的是**新项目里重复手写的加载流程**,不删除旧项目的业务文件。

# 可选拷贝工具 copyx
v0.19 用普通 Go 调用取代 JSON 结构映射生成。`copyx` 只依赖标准库,不需要注册到 App,不执行 JSON 往返,也不会自动暴露数据库模型。普通 Logic 直接使用 `.api` 生成的 DTO;只有存在独立业务类型或需要隔离可变数据时才用它。
完整可运行代码:[examples/copying](examples/copying)。在框架根目录运行:
```sh
go run ./examples/copying
go test -race ./copyx ./examples/copying
```
## 最简单的调用
```go
import "git.yuntuo.hk/k2safe/go-omni/copyx"
type Request struct { Name string; Enabled bool }
type Input struct { Name string; Enabled bool }
req := Request{Name: "sample", Enabled: false}
var input Input
if err := copyx.Copy(&input, req); err != nil { return err }
```
同名、同类型字段直接赋值。默认不会跳过 `false`、`0`、空字符串。目标字段没有来源时报错;多余源字段默认忽略,使用 `WithStrictFields()` 可要求源字段也全部使用或显式忽略。
默认是浅拷贝:同类型指针、map、slice 共享引用,符合普通 Go 赋值。JSON tag 不参与字段匹配。不会自动调用方法、SQL Scanner/Valuer,或把 `int32`、`int64`、string、命名标量互相强转。
新字段:普通接口只改 `.api` 和使用该字段的 Logic。独立 DTO/业务类型都需要此字段时,两边各声明一次;同名同类型不增加拷贝配置。检查在运行时发生,实际类型对必须有测试,不能把运行时工具当作旧生成器的编译期字段覆盖检查。
## 深拷贝与构造器
```go
snapshot, err := copyx.Clone(source) // 保持源的静态类型,始终深拷贝
if err != nil { return err }
copier, err := copyx.New(copyx.WithDeepCopy(), copyx.WithStrictFields())
if err != nil { return err }
var result Output
if err := copier.Copy(&result, source); err != nil { return err }
```
`Copy` 的目标必须是非 nil 指针;`Clone[T]` 返回 `(T, error)`。重复执行时在初始化阶段创建 Copier 并复用;配置之后不可变,每次调用独立持有遍历状态,可以并发使用。源、目标的并发读写仍由调用方同步,自定义函数也须支持并发。
深拷贝会分配指针、map、slice,递归处理结构、数组、接口中的具体值。nil 集合与非 nil 空集合保持区别;slice 结果容量为长度,不复制长度之外的隐藏元素。普通循环和重复指针可处理。循环图应保留根指针,使用 `Clone(sourcePointer)` 或 `Copy(&targetPointer, sourcePointer)`;将循环指针根压成值结构会明确报错。
它保证结果不引用输入中的可变对象,不保证保留所有底层内存布局关系:不同重叠 slice 视图会分别复制,内部指针指向某个切片元素的关系也不重建。字符串和零尺寸值可安全共享;`time.Time` 按 Go 不可变值使用(Location 不做独立复制)。不要通过 unsafe 或 uintptr 隐藏可变引用后要求工具识别。
## 字段差异与自定义转换
```go
type Input struct { Name string; UpdatedAt time.Time; InternalID string }
type View struct { DisplayName string; UpdatedAt string; LocalNote string }
copier, err := copyx.New(
copyx.WithDeepCopy(),
copyx.WithStrictFields(),
copyx.WithFieldNames[Input, View](map[string]string{"Name": "DisplayName"}),
copyx.WithIgnoreSource[Input, View]("InternalID"),
copyx.WithIgnoreTarget[Input, View]("LocalNote"),
copyx.WithConverter(func(v time.Time) (string, error) {
return v.UTC().Format(time.RFC3339), nil
}),
)
if err != nil { return err }
out := View{LocalNote: "preserve"}
if err := copier.Copy(&out, input); err != nil { return err }
```
字段规则的类型参数必须是结构类型,字段名使用导出的 Go 字段名。构造时检查不存在的字段、重名及冲突。不支持字符串路径表达式;复杂嵌套差异为该嵌套类型注册 converter,或直接写 Go。
`WithIgnoreSource` 只是声明该源字段不参与使用;目标同名字段若仍需保留,还需 `WithIgnoreTarget`。忽略目标会保留原目标值,Clone 中则为零值。深拷贝时如果保留值仍与源共享可变引用,也会拒绝。
转换器的签名是 `func(S) (T, error)`,按**精确类型对**匹配,不能重复注册。金额、编号、日期格式由项目明确转换。需要逐字段不同规则时,给整个源/目标结构注册函数;函数返回独立的新目标。无需另一份映射配置或全局注册。
精确 converter 优先于 nil/零值策略,能收到 typed nil;例如 `func(*Money) (Money, error)` 可自行决定 nil 是否允许。绑定到 `any` 字段的 converter 能接收 nil interface,但顶层未带类型的 `nil` 没有精确类型可匹配。浅拷贝中已经直接共享的同类型容器不会继续逐项转换其内部;需要遍历内部时选择深拷贝,或为该容器类型注册 converter。
## 深拷贝不能原样返回可变引用
```go
copier, err := copyx.New(
copyx.WithDeepCopy(),
copyx.WithConverter(func(v []string) ([]string, error) {
return v, nil // 会返回 ErrSharedReference
}),
)
```
检查覆盖完整源图与转换结果,包括新父对象引用旧子对象、原 map、重叠子切片、`source[:0]` 的可写容量、指向源数组元素的指针,以及未导出字段中的引用。会检查每个 converter 的结果和最终目标,不允许静默降级为浅拷贝。
返回相同字符串、整数并不会报错,它们不是可变引用。正确切片 converter 可以写:
```go
copyx.WithConverter(func(v []string) ([]string, error) {
if v == nil { return nil, nil }
out := make([]string, len(v))
copy(out, v)
return out, nil
})
```
第三方 Decimal/自定义 Money 如果含未导出的指针,默认深拷贝拒绝;注册该类型的 converter,使用它自己的构造/Clone API 创建独立值,避免转成 float64 损失精度。框架不内置某一金额库的规则。无法独立复制的类型直接返回错误。
## nil、零值和错误
| 选项 | 行为 |
| --- | --- |
| 默认 `NilError` | nil → 可空目标保留 nil;nil → 非可空目标报 `ErrNil` |
| `WithNilPolicy(NilZero)` | 显式允许 nil → 零值;可空目标仍为 nil |
| `WithNilPolicy(NilSkip)` | nil 保留已有目标;新集合元素没有旧目标,保留元素零值 |
| `WithSkipZero()` | 显式跳过 Go 零值,包括 `false`、`0`、`""`;非 nil 空集合不是 Go 零值 |
所有 nil 策略都不把不兼容类型自动变成兼容类型。非 nil 指针与值之间可以按对应元素转换;nil 到非可空目标仍需选择策略。局部更新不能默认使用 NilZero/SkipZero,它们可能改变清空字段或布尔值的业务语义。
工具只能复制绑定后的 Go 值:如果输入类型已经将“缺失”和“JSON null”合并为 nil,无法恢复两者区别。需要三态时,应先设计包含 presence 信息的类型和绑定逻辑。
赋值使用临时结果,成功后才替换目标;转换失败不会交付部分结果。`*copyx.Error` 包含 Go 字段/索引路径,`errors.Is/As` 保留内部错误链,工具不主动在错误中加入源值。converter 自己返回的错误文本仍由项目负责。
converter 必须只读输入;其外部副作用、输入修改无法回滚,panic 原样传播。框架只检查与本次输入的共享引用,无法证明 converter 未返回外部全局缓存的引用。它是受信 Go 代码扩展,不是可运行不可信代码的沙箱。
## 支持范围与资源限制
- 支持结构体、指针、interface、slice、同长度 array、map。map key 转换后冲突或不可比较则报错。
- 导出匿名结构字段可按提升后的无歧义名称访问;源嵌入指针为 nil 且需要其字段时明确报错。跨类型目标包含私有字段时拒绝;同类型私有纯值可作为整体保留。
- 不克隆文件、数据库连接、网络连接、锁、原子状态。已知标准库资源/同步结构按值复制也拒绝;深拷贝中的非 nil func、chan、unsafe.Pointer 拒绝。其他封装资源类型应由项目排除,工具不能识别所有自定义句柄。
- 单次遍历深度上限 256、节点上限 200,000;内置分配的估算预算为 64 MiB,超限返回 `ErrLimit`。预算不是进程堆内存硬限制,reflect 元数据和 converter 自行分配不计入。大对象流式读写应使用 IO/存储接口。
- 只缓存不可变类型元数据,不缓存请求值、用户 converter 或实例策略。没有 `unsafe` 写入、JSON 往返、隐式数值截断或方法调用。
- 这是运行时反射工具,会比直接 Go 赋值多检查与分配。热点应复用 Copier,并用真实数据测量;性能记录见 [本版验收](reports/copyxAcceptance.md)。
## 从旧 mapping 迁移
v0.19 **彻底移除**映射配置加载、Go 类型加载、映射代码生成及 `pointerResult` 等附属选项。公共 `.api` 字段组合、scalar、中间件工厂、Repository 开关继续存在。
1. 先检查每个转换是否必要。普通 Logic 可直接使用生成 DTO;独立核心保留自己的类型。
2. 将 `mapping.Xxx(...)` 调用改为普通 Go 或小型 `copyx` helper。字段改名、nil、金额规则写在该 helper 同一处。指针返回可直接 `var out *Response; err := copier.Copy(&out, input)`。
3. 用真实类型对测试缺失/null/零值/空数组、字段覆盖、金额精度和错误链。需要源字段新增时提醒遗漏,启用 `WithStrictFields()` 并测试。
4. 从 `omni.gen.json` 删除 `mappings` / `mappingFiles`,删除无其他用途的映射 JSON 文件。
5. 确认已无调用,再删除 `internal/mapping/mappingsGen.go`。如之前手改过文件,先迁出手写内容。生成器遇到该旧文件会阻止生成并提示迁移,**不会静默删除**;其余业务文件照常保留。
6. 升级框架与 CLI 到同版,执行 generate、generate --check、go test ./...;多个服务再执行 workspace generate/check。新 manifest 自动去掉已移除文件的所有权记录。
历史发布记录保留旧能力说明,仅用于理解旧版本,不代表 v0.19 继续支持。

# 通用业务开发指南(v0.21.0-preview)
从 [README](README.md) 创建服务后,业务主要维护 `.api`、配置、`svc.Init`、Logic、Repository 和项目中间件。本页说明通用接入能力;字段、错误码、权限、表结构和事务边界都由项目定义。
公共字段组合、自动中间件工厂和 Repository 开关,见 [生成能力指南](GENERATION.md)。必要的结构转换使用可选 [copyx](COPY.md),v0.19 已移除旧 JSON 映射生成。
## 返回数组、可空对象和 null
```text
@handler list
get /items returns ([]Item)
@handler find
get /item returns (*Item)
@handler save
post /item returns (null)
@handler remove
delete /item
```
| 契约 | Logic 返回 | 成功数据 |
| --- | --- | --- |
| `returns (Item)` | `(*types.Item, error)` | 对象;nil 被视为实现错误 |
| `returns ([]Item)` | `([]types.Item, error)` | 对象数组;nil 统一输出 `[]` |
| `returns ([]string)` | `([]string, error)` | 字符串数组 |
| `returns ([]int64)` / `([]bool)` | `([]int64, error)` / `([]bool, error)` | 数值 / 布尔数组 |
| `returns ([]any)` | `([]any, error)` | 动态 JSON 数组,元素允许对象、数组、标量和 null |
| `returns (*Item)` | `(*types.Item, error)` | 对象或 `null` |
| `returns (null)` | `error` | HTTP 200 和空业务数据 |
| 不写 returns | `error` | HTTP 204,无响应体 |
统一响应中的空数据是否显示,仍遵循项目模板的 `dataMode`;需要 `data:null` 就设置 `dataMode: always`。`@response raw` 输出业务数据本身,包括 `[]`、对象或 `null`。可用 `@status 201/202`;204 不能声明响应类型。嵌套字段继续支持既有 slice/map/pointer/scalar/any。
基础类型数组还支持 int/int8/int16/int32、uint/uint16/uint32/uint64、float32/float64。nil 根数组都输出 `[]`;`[]any` 在 OpenAPI 中是 `type: array, items: {}`,不限制元素形状,但元素必须可被标准 JSON 编码器序列化。`[]uint8`(Go 的 byte slice)会编码为 base64,故明确拒绝;数字数组可用 `[]int32`,二进制用下载接口。当前不支持根嵌套数组或根自定义 scalar 数组。
## 契约驱动的请求策略
入口文件可以声明默认策略,单个接口按需覆盖:
```text
@app (
defaultResponse: CommonResponse
request: {"unknownQuery":"reject", "utf8":"reject", "charset":"utf8"}
)
@handler create
@request (body: required)
post /items (CreateReq) returns (Item)
@handler touch
@request (body: emptyObject)
post /touch returns (null)
```
- `unknownQuery: reject|ignore`:是否拒绝未声明的 URL 查询字段;重复标量仍拒绝,数组用重复的同名 query。
- `utf8: reject|replace`:拒绝原始非法 UTF-8,或采用 JSON 的替换字符行为。不是只检查解码后的字符串。
- `charset: utf8|any`:`utf8` 仅接受未声明 charset 或 `utf-8`;不会对其他编码做转码。
- `body: auto|required|optional|none|emptyObject`:auto 按 JSON 字段推断;required 要求一个对象;optional 允许完全没有 body,但提供 body 后仍完整校验;none 禁止任何 body 字节;emptyObject 必须是 `{}`。
未设置的项继承 App 的 `config.Config.Request`,最后采用既有默认行为。`.api` 的 `@app` 显式字段优先于项目配置;路由 `@request` 优先于 App。raw/multipart 使用各自解析流程,不能套 JSON body 策略。普通 JSON 只解析一次;重复/未知 JSON 字段、约束、scalar 和 `any` 仍使用同一编译器。自定义 binder/manual Handler 的输入逻辑由项目显式负责。
没有 body 与提供 `{}` 不等价。optional 无 body 时 JSON 字段保留零值;需要业务区分是否出现某字段时使用 optional 指针字段。raw/multipart 不继承 App 的 JSON body 策略;GET/HEAD 如遇 App 的 required/optional/emptyObject 默认值,须明确覆盖为 auto 或 none。参数校验不会替代企业权限、记账规则或数据库约束。
## 声明式 multipart
```text
type UploadReq {
Title string `multipart:"title" binding:"required,max=80"`
Metadata AttachmentMeta `multipartJSON:"metadata,maxBytes=16384"`
Attachment File `file:"attachment,maxBytes=10485760"`
Extras []File `file:"extras,optional,maxFiles=3,maxBytes=1048576"`
}
type AttachmentMeta {
Category string `json:"category"`
}
@handler upload
@body (mode: multipart; maxBytes: 16777216; maxParts: 8; maxFieldBytes: 65536)
post /attachments (UploadReq) returns (AttachmentResp)
```
Logic 直接得到 `*types.UploadReq`,无需维护 Handler。`form` 仍表示 URL query;`multipart` 表示文本表单字段,可用基础类型、文本 scalar 和重复 scalar 数组;`multipartJSON` 是一个严格解码的 JSON 表单字段,可包含对象、数组和已声明的 scalar。
`File` 提供 `Name`、`ContentType`、`Size`、`Present()` 和 `Open() (io.ReadCloser, error)`。文件名和媒体类型属于客户端元数据,项目继续决定内容检测、存储权限和目标对象名。不要把客户端文件名直接用作存储路径。
```go
reader, err := req.Attachment.Open()
if err != nil { return nil, err }
defer reader.Close()
// 将 reader 传给项目选定的流式存储接口;不要先 io.ReadAll 整个大文件。
```
所有声明字段、重复/未知字段、文件数量和各级限额都会在进入 Logic 前校验。缺少必填项、重复标量/JSON 字段、文件与文本类型混用、畸形 JSON 均失败。JSON 的类型、未知字段和重复 key 检查与普通 JSON 一致。
默认总量 1 MiB、最多 128 个 part、单文本/JSON 字段 64 KiB;单文件默认受总量约束,文件数组默认最多 16 个。`@body` 可设置 `maxBytes/maxParts/maxFieldBytes/maxFileBytes`;字段上的 `maxBytes/maxFiles` 再收紧对应限额。总量包括 MIME 头和结尾数据;传输编码的 part 被拒绝,避免字节含义不明确。
文件使用有界复制写入权限为 0600 的临时文件,文本/JSON 字段在各自限额内缓冲。生成 Handler 返回或 panic 时关闭打开的文件 reader 并删除临时文件;不能把请求的 File 留到异步任务使用。失败不会交付半个 DTO,也不会进入 Logic。临时磁盘容量、并发请求上限与 HTTP 超时由部署配置共同约束。
不声明 multipart 字段时,保留原来的 `body *httpx.Body` 流式入口,不创建临时文件。该方式适合特殊协议;项目应在不可撤销副作用之前完成校验并调用 `body.Complete()`。下载和原始回调继续使用 `@produces` / `@body(mode: raw)`。
## 完整业务配置的环境覆盖
生成器维护 `internal/config/loadGen.go`;项目维护 Config/Default/Validate 和可选 NewLoader。三种格式、可扩展解析器、字段错误定位及旧 Load 迁移见 [统一配置指南](CONFIG.md)。
生成项目默认执行:代码与 `envDefault` 默认值 → JSON/YAML/XML 文件 → 全结构体环境覆盖(含别名)→ 规范化 → `Validate`。增加业务字段不需要另外写 `os.Getenv`。
```go
type ClientConfig struct {
Endpoint string `json:"endpoint" env:"CLIENT_ENDPOINT,required"`
Token string `json:"-" env:"CLIENT_TOKEN,required,secret,empty=reject"`
Timeout time.Duration `json:"timeout" envDefault:"3s"`
Retries []int `json:"retries"`
Enabled bool `json:"enabled"`
}
```
把字段加入项目 `Config` 后,默认环境名取 `GO_OMNI_` 加 JSON 路径的 UPPER_SNAKE_CASE,如 `GO_OMNI_CLIENT_TIMEOUT`。显式 env 名是完整名称,可以使用自己的业务前缀。`env:"-"` 排除整个子树;`json:"-"` 字段只有显式 env 标签才参与。
duration 使用 `250ms`、`3s`;slice/map 使用 JSON,如 `[1,3,5]`、`{"retry":"2s"}`。支持嵌套、零/false、空数组、自定义 TextUnmarshaler。空环境值默认允许;可选择 `empty=ignore` 或 `empty=reject`。required 要求字符串非空、指针/集合非 nil;0 和 false 可以是合法业务值,范围由项目 Validate 决定。
手写项目可使用 `config.LoadProject(path, defaults, config.EnvOptions{Prefix:"MY_APP_"})`,或分别调用 `ApplyDefaults/DecodeFile/OverlayEnv`。读取失败不修改输入默认值;诊断不会打印输入值。不要主动打印含密钥的整个配置,或把底层解析错误展开到公开响应。Validate 不打开日志文件、数据库或存储连接;证书的可读性和握手信任在依赖初始化阶段验证。
### 一次覆盖完整配置与 HTTP/日志短名称
```go
cfg, err = config.OverlayEnv(cfg, config.EnvOptions{
Prefix: "MY_APP_",
Empty: "reject", // allow / ignore / reject,项目自行选择
Aliases: config.ServerEnvAliases("MY_APP_", "server"),
// Lookup 可注入测试或项目配置源;默认 os.LookupEnv。
})
```
不要再紧接着调用 `ApplyEnv(cfg.Server, ...)`。上面的调用同时处理完整配置和 HTTP_ADDR、SERVICE、LOG_LEVEL 等框架短名称。例如 `MY_APP_SERVER_ADDRESS` 与 `MY_APP_HTTP_ADDR` 指向同一字段,**完整名称优先**;未设置时才读取短名称。完整名称显式设空仍优先:allow 交给该字段解析(string 可清空;数字等仍要求合法值),ignore 保留文件/默认值,reject 报错。不会因 ignore 再退回别名。字段 `env` 标签的 empty 规则优先于全局规则。
自定义别名用 `EnvOptions.Aliases`,键是完整环境名、值是按优先级排列的别名数组。两种名称都使用同一 Lookup、空值策略和类型转换;布尔 false、数值 0 与未设置不同。集合始终使用 JSON,包括 `MY_APP_TRUSTED_PROXIES='["127.0.0.1"]'`。
新项目模板一次调用 OverlayEnv,默认 `Empty: "ignore"`。旧 `ApplyEnv` 保留原有忽略空值、修剪空白及 TRUSTED_PROXIES 逗号列表行为。已有项目的 `internal/config` 属于开发者文件,升级不覆盖它;按上例合并原来的两次覆盖调用后,保留项目自己的 Validate。日志输出的显式完整名称也优先于短名称。
## 依赖、日志与中间件
`internal/svc/runtimeGen.go` 持续由生成器维护。项目的 ServiceContext 嵌入 `*lifecycle.Runtime`,只在 `Init(ctx)` 中装配额外依赖:
```go
func (c *ServiceContext) Init(ctx context.Context) error {
client, err := NewClient(c.Config.Client)
if err != nil { return err }
c.Client = client
c.OnClose(client.Close)
return nil
}
```
每个资源初始化成功就登记清理;后续初始化失败自动逆序回滚。正常退出先排空 HTTP 请求,再执行后台组件的 Stop/Drain 阶段,确认收尾后逆序关闭依赖,最后关闭日志。关闭幂等,单个清理函数 panic/返回错误不会跳过其他清理;初始化 panic 清理后继续传播。后台组件按 [分阶段关闭](lifecycle/README.md#后台组件分阶段关闭) 登记;无法确认收尾完成时保留共享依赖并异常退出,不能把取消等同于任务已经结束。
新项目使用中间件工厂:项目维护 `middleware.Dependencies` 小接口与 `New<Name>(deps) (httpx.Middleware, error)`,svc 提供对应访问器。生成的 runtime 在 Init 成功后自动调用工厂并注册,不再按名字替换 map;工厂失败会释放已经登记的依赖。示例与现有项目迁移步骤见 [中间件工厂](GENERATION.md#中间件工厂自动注册)。
v0.16 项目及 `omni.gen.json` 中选择 `middleware: handlers` 的项目继续使用原有 `Defaults()`,可以在 Init 设置 `c.Middlewares["RequireAccess"]`。更新时不会重写这部分业务代码;只有显式切换到 factories 后才使用新流程。
生成入口为每个 App 注入独立 Logger,不修改进程默认 Logger。业务可用 `c.Logger.InfoContext(...)`,或请求链中的 `logx.InfoContext(ctx,...)`。标准库/第三方需要 `*log.Logger` 时使用 `c.Logger.Standard(slog.LevelWarn)`;适配器借用原 Logger,不负责关闭。手写多 App 用 `omni.WithLogInstance(logger)` 显式注入。
`httpx.Metadata(ctx)` 在业务的标准 context 中提供可信代理规则解析后的 ClientIP、HTTP Method 和路由模板;不放入凭据、完整 URL、查询或 body。业务 userId/tenantId 等仍由项目选择,框架不预设身份模型。
`middleware.ContextErrors("REQUEST_CANCELED", "REQUEST_TIMEOUT")` 可将原始取消/超时错误映射到项目错误目录;显式 APIError 优先,内部 cause 链保留。状态、业务码与提示仍在项目 Catalog 配置。
## 字段文档、格式化、Go 错误目录导出
```text
type Item {
// 企业名称
Name string `json:"name" example:"示例企业"`
State int `json:"state,options=0|1" example:"1" enumDescriptions:"[\"禁用\",\"启用\"]"` // 状态
}
```
字段前/同行注释同步到 Go 注释和 OpenAPI description。显式 `description` 标签优先;example 的基础字段值也检查类型和约束,枚举说明按声明值顺序填写。字符串 example 直接写内容,其他类型写 JSON。自定义 scalar 的示例不能替代其项目解码器验证;输入输出类型不同时,不把输入示例冒充输出示例。
```sh
go-omni api format --api api/service.api
go-omni api format --api api/service.api --check
go-omni api generate
go-omni api generate --check
```
格式化保留注释、token 和多行字面量,规范四空格缩进、空行、行首尾空白及相邻单行字段的类型/标签/行尾注释对齐;结果幂等。先校验完整契约,check 不写文件;导入的共享目录不被某个服务的格式化命令修改。DTO 按源 `.api` 输出 `dto<Source><摘要>Gen.go`,都属于 `types` 包,跨文件引用无需改包名。
Go Catalog 是错误的唯一来源时,优先使用 workspace 的显式导出配置,不再维护导出/复制脚本。AppOptions 仍通过 `omni.WithErrors(apierrors.Catalog())` 注册同一个 Go 函数,运行期只注册一次。单个项目也可继续使用 `errors.ExportCatalog` 导出入口目录的 `api/omni.errors.json`;此文件和下面的共享 source 二选一。
OpenAPI 自动把有收益的重复响应、schema 和示例移到 `components.responses/schemas/examples`,通过标准 `$ref` 引用。HTTP 200 同时含成功和业务失败时保留两种 schema、业务码、模板参数示例和 data:null;业务响应内容不会改变。消费 OpenAPI 的工具需要支持标准本地引用。
## 两个服务共享契约

├── services/id/api/service.api

两个服务的 `omni.imports.json` 可以分别声明:
```json

```text

只读取入口目录和显式声明的根。保留真实路径检查、symlink 越界拒绝、循环检测、32 层、64 文件、单文件 1 MiB/总量 8 MiB 限额;最多 16 个共享根。不会下载依赖或复制共享定义进服务。移动目录时显式更新 roots。
`version` 是项目管理的版本标签。生成文档记录每个文件 SHA-256,以及每个共享根所导入文件集合的摘要;可把文档中的 `x-omni-contract-sources.shared.common.sha256` 填入 root 的 `sha256`,固定输入集合,内容变化后必须显式更新。摘要算法是对“该根内相对路径→文件 SHA-256”的键排序 JSON 对象再做 SHA-256,未导入的文件不参与。
工作区清单:
```json
{"services":[{"dir":"services/api"},{"dir":"services/id"}]}
```
```sh
go-omni workspace format --file omni.workspace.json
go-omni workspace generate --file omni.workspace.json
go-omni workspace check --file omni.workspace.json
```
各服务保持独立 module;可显式填写各服务的 `api`(相对服务目录)和 `module`。所有服务预检通过后再写;每个服务独立提交文件事务,不承诺跨项目的崩溃原子性。check 汇总格式与生成漂移;业务编译/测试仍在各 module 执行。
### 同一份 Go 错误目录供多个服务生成
在 workspace 清单显式声明提供目录的 Go 包和函数:
```json
{
"errorCatalogs": [{
"dir": ".",
"package": "example.com/project/internal/apierrors",
"function": "Catalog",
"output": "contracts/common/errors.json"
}],
"services": [{"dir":"services/api"}, {"dir":"services/id"}]
}
```
`dir` 相对 workspace,必须包含 go.mod;函数签名为 `func Catalog() errors.Catalog`。允许 module 内的 internal 包。先准备 output 的父目录。生成器构建一个临时导出程序,使用 Go overlay、临时 go.mod/go.sum 和 `-mod=readonly`,不会往项目增加导出命令或修改 go.mod/go.sum。最多 16 个提供方,每个有 90 秒构建/执行总时限和 1 MiB stdout 限制。错误消息不回显程序输出。
只有显式运行 **workspace generate/check** 会执行清单指定的 Go 包及其依赖初始化;不要指向不信任的包。提供目录的函数应只构造目录,不连接数据库、启动服务、写 stdout 或修改项目。框架不扫描其他包,也不通过 shell 执行配置字符串。普通 api validate/export/generate 和 workspace format 只读取现有元数据。
各服务在自己的 `api/omni.imports.json` 引用共享 JSON:
```json
{
"roots": {"common":{"path":"../../../contracts/common","version":"1.0.0"}},
"errors": {
"source": "@common/errors.json",
"include": ["USERNAME_INVALID", "INTERNAL_ERROR"],
"routes": {"GET /permissions":["INTERNAL_ERROR"]}
}
}
```
`include` 省略或 null 表示全部目录,`[]` 表示不列业务错误;routes 按 **大写方法 + 空格 + .api 原路径**(如 `GET /users/:id`)覆盖服务级列表。错误标识、路由拼错或重复标识会明确报错。路由已经通过 `.api @errors` 声明独立运行期目录时,不能再给它设置文档 routes 列表。
**这些列表只决定文档展示,不修改 App 错误目录、路由继承或运行期可返回的错误。** `.api` 不需要重复定义 Go 错误表。状态、业务码、提示和模板参数仍来自同一 Catalog;特殊自定义 Encoder 的文档由项目显式扩展。
```sh
# 首次生成导出一次共享目录,所有服务预检通过才写入
# 共享 JSON 不复制到各服务;已有 api/omni.errors.json 请显式移除后改用 source。
go-omni workspace generate --file omni.workspace.json
go-omni workspace format --file omni.workspace.json
go-omni workspace generate --file omni.workspace.json
go-omni workspace check --file omni.workspace.json
```
共享 JSON 应纳入版本控制。check 在内存重新导出并比较 JSON,然后检查所有服务;缺失或过期时失败,不更新项目文件。Go 构建缓存仍可能更新;显式提供方的自有副作用不属于生成器可隔离范围。业务 CI 仍执行各 module 的编译与测试。目录函数本身有变化时重新 generate,受控共享根的固定 SHA256 如需改变仍由项目显式更新。
## v0.13 项目升级
先使用与目标框架匹配的 CLI;CLI 会提示与 go.mod 不同的版本。当前生成模板至少需要 v0.20.0-preview(或显式引用当前源码)。
```sh
go-omni api upgrade --dir . --dry-run
go-omni api upgrade --dir . --preview .goOmni/upgradePreview
# 只有标为 safe 的原始模板才会自动替换;review 阻止全部写入。
go-omni api upgrade --dir . --apply
go mod tidy
go-omni api generate --check
go test ./...
go build .
```
自动迁移只替换与 v0.13 原始模板一致的配置/svc 基础文件、移除原始 close.go,并更新最低依赖及生成产物;保留 Logic、Repository、AppOptions、独立命令。迁移失败回滚已改的项目文件。存在业务修改时,仅输出这些基础文件的候选版本和清单,不生成整棵业务代码让人重新拼接。
定制项目按预览定点迁移:保留依赖字段,把初始化移到 Init,嵌入 Runtime,清理改为 OnClose 登记;移除旧 New/Close/OnClose;合并业务配置和结构化 MySQL 配置,更新 go.mod,再正常 generate。生成器会拒绝遗留构造/关闭实现,避免重复函数或悄悄绕过清理。v0.12 及更早的定制结构不能被精确自动合并,使用同一预览逐项迁移并编译验证。

# 公共字段、中间件工厂与生成选项
本页对应 `v0.19.0-preview`。CLI 与框架依赖固定到同一版本,安装见 [README](README.md#准备环境与安装)。
## 一份项目生成配置
新项目根目录的 `omni.gen.json` 只描述生成选项:
```json
{
"repository": "none",
"middleware": "factories"
}
```
- `repository: none` 默认不创建空 Repository 文件;`group` 按 group 补齐可编辑骨架。已有文件始终保留;切回 none 不会删除业务文件。SQL、ORM 和仓储划分由项目决定。
- `middleware: factories` 是新项目默认值,自动调用带依赖的工厂。`handlers` 保留原有 `Defaults()` 及手动注册方式,供既有项目迁移。
- 该文件与 `.api` 一起提交。generate/check/dry-run 和 workspace 采用相同规则;validate/export/format 只处理接口契约。
- 旧 manifest 没有配置时补 `middleware: handlers`、`repository: none`。已有配置不能直接删除,避免意外切换中间件模式。
- v0.19 已删除 `mappings` 和 `mappingFiles`;遇到旧配置会明确报错,不读取子映射文件或执行映射生成。处理步骤见 [copyx 迁移](COPY.md#从旧-mapping-迁移)。
## 公共字段组合
```text
type EmployeeFields {
// 员工姓名。
Name string `json:"name" binding:"max=80"`
Salary Money `json:"salary"`
}
type EnterpriseRequest {
EmployeeFields
}
type AdminRequest {
EmployeeFields
CompanyID string `path:"companyId"`
}
```
`Money` 由项目按既有 scalar 语法声明。组合行只有已声明的对象类型名,不加指针或字段 tag。公共对象可以通过已有相对 import 或声明过的共享根 `@common/...` 引入。
生成器展开为普通 Go 字段。JSON 保持平铺;字段的绑定来源、校验、注释、可空性和 OpenAPI 使用同一份展开结果。不会在 JSON 中增加 `EmployeeFields` 一层。重复 Go 字段、重复来源字段名、循环组合、未知对象和过深展开均失败;即使重复字段类型相同,也不能隐式覆盖。要改变某个字段的规则,应拆出更小的公共组合。
允许多层组合,上限 32 层、单类型 4096 字段、全契约展开 65536 字段。Go 匿名指针嵌入并非本功能;生成 DTO 中不会使用匿名嵌入。
## DTO 与业务类型
普通 Logic 直接接收生成的 Request、返回生成的 Response,不额外创建相同结构。只有独立核心或明确不同的输入/输出职责才保留业务类型。
必要转换直接写 Go,或用可选 `copyx.Copy(&target, source)`。同名同类型字段自动赋值,字段改名和类型变化通过 Go 参数、转换函数明确设置,见 [完整示例](examples/copying/main.go)。无需 JSON 映射配置、包路径字符串或额外生成文件。
`copyx` 在运行时检查类型和字段,**不提供旧映射生成阶段的静态字段覆盖保证**;CI 应给实际类型对添加测试。普通业务字段新增通常只改 `.api` 和 Logic;独立 DTO/领域类型都需要此字段时,两边各加一次,同名同类型无需追加拷贝配置。
## 中间件工厂自动注册
`.api` 沿用 `middleware: RequireAccess` 或 auth 对应的中间件声明。新项目会生成可编辑的 `internal/middleware/requireAccessFactory.go`,只需实现一次:
```go
// internal/middleware/dependencies.go,由项目维护。
type AccessChecker interface {
CheckAccess(context.Context, string) error
}
type Dependencies interface {
AccessChecker() AccessChecker
}
// internal/middleware/requireAccessFactory.go,由项目维护。
func NewRequireAccess(deps Dependencies) (httpx.Middleware, error) {
checker := deps.AccessChecker()
if checker == nil { return nil, errors.New("access checker is required") }
return func(next httpx.Handler) httpx.Handler {
return func(c *httpx.Context) error {
if err := checker.CheckAccess(c.Context(), c.Header("Authorization")); err != nil {
return err
}
return next(c)
}
}, nil
}
// internal/svc/access.go,由项目维护;ServiceContext.Init 初始化 c.Auth。
func (c *ServiceContext) AccessChecker() middleware.AccessChecker { return c.Auth }
```
编译器检查 ServiceContext 是否实现依赖接口,middleware 不导入 svc。多个工厂可以共用这些小接口。所需 imports 和具体鉴权服务仍属于项目。
启动顺序为:框架基础依赖 → `svc.Init` → 生成的 `middleware.New(c)` 调用各具名工厂 → 创建 App/注册路由 → 监听。中间件实例创建一次,由请求并发复用;不要把单次请求信息存在实例字段里。工厂之间没有初始化顺序依赖;路由执行顺序仍以 `.api` 声明为准。
工厂返回错误或 nil 中间件均阻止监听;错误链保留,已登记资源按现有生命周期清理。工厂 panic 也先清理依赖再传播。资源初始化和清理登记放在 svc.Init,工厂借用资源;HTTP 请求排空之前不会关闭这些依赖。
factory 模式不再在 Init 写 `Middlewares["..."]`;残留非空手写注册表会明确报错,防止生成注册静默覆盖它。未实现的工厂让启动失败;未实现的 Logic 仍返回 501。
### 既有项目迁移
1. 首次更新保持 `middleware: handlers`,现有 hook 和手写 Configure 不变。
2. 改为 factories 并重新生成,会补 `dependencies.go` 和 `*Factory.go`,保留原来的手写文件。
3. 将旧实现迁入工厂,提供 Dependencies 的访问器;移除 Init 中按名字覆盖 map 的代码。
4. 旧函数不再需要时由项目删除。若新工厂符号与旧文件中的同名函数冲突,整理旧文件;生成器不覆盖业务代码。
5. `generate --check` 与 `go test ./...` 检查后再运行。工厂没有全部实现前,服务不会启动。

## 请求追踪与基础指标
`omni.New()` 的默认链包含 RequestID、访问日志(可配置开关)和 Recovery;无需重复挂载。业务通过 `c.Context()` 传递 requestId,`logx.FromContext(ctx)` 取得该 App 的 Logger。手动组装 httpx 链时,也可使用 `middleware.RequestID("X-Request-ID")`、`middleware.AccessLog()` 和 `middleware.Recovery()`。

## 依赖主动申请退出
从 v0.13.0-preview 起,生成的 svc 提供 `RequestShutdown(err)`。数据库客户端、节点租约、后台任务等发现不可恢复故障时,由项目决定是否退出:
```go
// 在 svc 的依赖监控回调中调用;err 是实际故障原因。
c.RequestShutdown(err)
```
这只是通知,立即返回,不等待 HTTP 排空,也不直接关闭数据库。生成入口停止接收新请求,等待在途请求完成;超过 `shutdownTimeout` 后取消请求并关闭连接,再执行 svc.Close,最后关闭日志。非空故障原因保留在返回错误链中,进程退出码为 1;`RequestShutdown(nil)` 或正常 SIGINT/SIGTERM 在没有其他故障时退出码为 0。
多个依赖可并发通知,关闭流程仅执行一次,首个非空故障原因保留。正常信号已开始排空时收到的故障也不会被清理动作覆盖。初始化期间的通知同样有效,不依赖 HTTP 监听已经启动。后台监控任务应通过 OnStop/OnDrain 停止并等待,再进入资源清理;关闭完成以后才报告的故障无法参与已经结束的进程结果。
`Lifecycle *lifecycle.Controller` 是 svc 持有的通用控制器,初始化时创建,生成入口使用它的 Context。该 Context 表示服务正在停止,不代表数据库已经关闭。不能把它当作在途请求的 Context,也不要在它取消时立刻关闭请求仍依赖的资源。发号器失去租约后拒绝发号等业务安全规则仍由项目实现。
配置加载入口 `internal/config/loadGen.go` 也由生成器维护。业务扩展 Config/Default/Validate;只有新格式才需要修改 NewLoader。JSON/YAML/XML、错误定位和旧 Load 迁移见 [配置指南](CONFIG.md)。
## 配置内置接口
生成项目在 `etc/config.yaml` 明确列出以下默认配置;可以独立关闭、修改路径,或让健康接口返回原始 JSON:
```yaml
server:
endpoints:
liveness:
enabled: true
path: /health/live
responseMode: app
readiness:
enabled: true
path: /health/ready
responseMode: app
openapi:
enabled: true
path: /openapi.json
```
`responseMode: app` 使用项目 App 的响应模板/自定义 Encoder。健康成功使用项目成功码和成功提示;未就绪的 `NOT_READY` 可在项目 Go 错误目录配置业务码和公开提示,无需在 `.api` 再声明。
健康探针的 HTTP 状态固定遵循探针语义:存活/就绪为 200,未就绪为 503;项目错误目录或自定义编码器不能把未就绪改为 HTTP 200。响应模板 `${status}` 同样使用探针状态。失败继续进入业务失败日志/指标,探针底层原因保留在错误链供日志使用,不直接返回给调用方。
`responseMode: raw` 返回 `{"status":"ready"}` 等健康数据,有依赖时包含检查名称、结果与耗时;不包装公共体。存活检查不执行依赖探针;服务开始退出后,就绪检查返回 503,存活仍可返回 200,直到监听关闭。OpenAPI 始终输出规范文档本身,不使用业务响应包装;关闭 HTTP 文档端点不影响生成 `docs/openapi.json`。
环境变量覆盖配置文件,例如 `GO_OMNI_ENDPOINTS_READINESS_PATH=/readyz`、`GO_OMNI_ENDPOINTS_READINESS_RESPONSE_MODE=raw`、`GO_OMNI_ENDPOINTS_OPENAPI_ENABLED=false`;liveness/readiness/openapi 都支持对应的 ENABLED 和 PATH。Config/AppOptions 的最终有效配置决定是否注册。
关闭或改名后,旧路径不再由框架保留,项目可以在 `.api` 自己声明。启用的内置 GET 路由与业务路由相同或被业务参数/通配路径覆盖时,在创建 App、开始监听之前报错;不会覆盖业务路由。内置接口仍经过全局中间件;项目在鉴权中间件中明确决定这些路径的访问规则,框架不自动绕过鉴权。

- Parts 是 `*httpx.MultipartReader`,返回的 `*httpx.MultipartPart` 提供 Read、Close、Header、FormName、FileName;NextRawPart 可读取未做 quoted-printable 解码的部分。NextPart 自动关闭上一个未读完的 Part;Close 会报告读取错误。不要混用 Parts 与 Raw 读取同一个 multipart 请求。
- multipart 缺少结束边界、头部/内容损坏默认返回 `400 / INVALID_MULTIPART`;超过路由限额仍为 413,媒体类型/缺少 boundary 为 415。框架只提供通用标识和默认提示,项目可以在 Go 错误目录中配置自己的状态、业务码和文案。内部解析原因保留在错误链,不进入公开响应;Logic 自己返回的数据库等错误不会被统一改成 400。

每个独立服务生成一个项目,module 名称、上层目录和共享业务包由项目选择。接入时固定 CLI 与框架版本为 v0.21.0-preview:
1. 先保留旧服务,整理实际路由及现有响应、鉴权和超时要求。在新目录执行 `go-omni new --api /path/to/service.api --module example.com/service ./service`;不对旧入口强制覆盖。
2. 在 `.api` 中选择 `@app(defaultResponse: ...)`,显式保留原项目的字段、成功码、错误码和 `dataMode`。需要独立回执的路由单独声明 raw/produces。普通路由、404/405 和提前返回的中间件一起验收。

GoOmni 是面向多个业务项目复用的 Go 后端框架:用 `.api` 定义接口、请求和返回类型,生成项目目录、HTTP 接入代码及 OpenAPI,业务代码负责 Logic 和 Repository。也可以在已有项目中直接使用 `omni.New()`,或单独引入日志、存储等模块。
**从这份 README 开始接入。** 当前版本 **`v0.12.0-preview`**,新生成项目采用根目录入口和 `config / svc / logic / handler`。可以固定版本开展业务接入;文件维护边界和已有服务迁移步骤见 [项目指南](PROJECT.md),版本变化与验收见 [发布说明](RELEASE.md)。
**从这份 README 开始接入。** 当前版本 **`v0.21.0-preview`**,新生成项目采用根目录入口和 `config / svc / logic / handler`。可以固定版本开展业务接入;文件维护边界和已有服务迁移步骤见 [项目指南](PROJECT.md),版本变化与验收见 [发布说明](RELEASE.md)。
**v0.19 改动**:新增可选 `copyx` 工具,用普通 Go 调用完成浅拷贝、深拷贝和显式类型转换;深拷贝会拒绝自定义转换中残留的源对象可变引用。**移除了 `mappings` / `mappingFiles` 和映射代码生成**,已有使用者须按 [迁移步骤](COPY.md#从旧-mapping-迁移) 调整,不能直接删除仍在调用的旧文件。
普通接口的流程是:**修改 `.api` → 生成 Request/Response → 写 Logic → 测试**。有独立职责的业务类型才需要转换;可直接写 Go,也可以按需使用 [copyx](COPY.md)。公共字段组合、中间件工厂、Repository 开关继续支持,见 [生成能力指南](GENERATION.md)。
Go **1.22+**。框架不依赖 Gin,默认使用标准库网络层,提供可切换的 native HTTP/1.1 和实验性 HTTP/2 适配器。
响应字段、业务码、登录方式、权限规则和数据库表结构由接入项目决定。文中的 `code/msg/data`、`200/9999` 都是示例配置,可以替换。
契约支持 `returns([]string/[]int64/[]bool/[]any)`、OpenAPI 公共引用、workspace 一次导出共享 Go 错误目录,以及统一环境变量别名覆盖。详细配置与升级步骤见 [业务开发指南](DEVELOPMENT.md)。
已有通用开发能力见 [业务开发指南](DEVELOPMENT.md):数组/null、严格请求策略、声明式上传、完整配置环境覆盖、资源生命周期、共享契约和升级工具。MySQL 直接使用 [官方适配器](database/mysql/README.md)。
后台组件可在 svc 登记 [分阶段关闭](lifecycle/README.md#后台组件分阶段关闭),先停止接收工作并等待收尾,再关闭共享资源;无需绑定队列或 ORM。
使用 GORM 的项目可以选择 [gormx 适配器](database/gormx/README.md),复用数据库初始化和连接池,并将 SQL 日志接入 logx。

## 带认证的出站 HTTP
HTTP Client 在 svc 初始化一次,业务重复使用。普通内部请求可直接选择直连和连接参数,无需手写 Transport:
```go
client, err := httpc.New(httpc.Config{
Proxy: httpc.ProxyConfig{Mode: httpc.ProxyDirect},
Timeout: 3*time.Second, DialTimeout: time.Second,
TLSHandshakeTimeout: time.Second, ResponseHeaderTimeout: time.Second,
MaxConnsPerHost: 32, MaxIdleConnsPerHost: 16, MaxIdleConns: 64,
})
if err != nil { return err }
// 在 svc 生命周期登记 client.Close;关闭前先排空使用它的工作。
err = client.JSON(ctx, "GET", endpoint, nil, &result,
httpc.WithHeader("Authorization", "Bearer "+token),
httpc.WithMaxResponseBytes(64<<10),
)
```
请求头只作用于本次调用,不把用户 Token 留在共享 Client。默认代理/参数保持原行为;也可选择环境代理或固定代理。JSON 自动关闭并限制响应,Do 保留下载/流式读取扩展。完整配置、重试边界和已有自定义 Transport 的迁移见 [httpc](httpc/README.md)。
```sh
go run ./examples/httpClient
```
## 统一配置加载
新生成项目的加载流程由框架管理。业务在 `internal/config/config.go` 增加字段、默认值和 `Validate`,无需改 main 或复制环境变量解析。JSON、YAML、XML 共用字段和校验;扩展格式在 `loader.go` 注册。
```go
// 项目 Config 中增加字段,自动支持 GO_OMNI_BATCH_SIZE:
BatchSize int `json:"batchSize" envDefault:"100"`
// 项目 Validate 中增加业务范围检查:
if c.BatchSize < 1 {
return omniConfig.Invalid("batchSize", "must be positive")
}
```
错误包含文件、字段、可用的行列或环境变量名;输入原值不自动写入错误。
```sh
go run ./examples/configuration -format xml
DEMO_CLIENT_TIMEOUT=500ms go run ./examples/configuration
```
详见 [统一加载、解析器、迁移](CONFIG.md) 和 [完整示例](examples/configuration/README.md)。**旧项目须先迁移手写 Load,再重新生成**;生成器会保留业务配置并拒绝冲突,不静默覆盖。

### 可选结构转换与深拷贝
普通接口不需要任何拷贝配置,直接使用生成的 Request/Response。独立业务结构之间有转换需求时:
```go
// import "git.yuntuo.hk/k2safe/go-omni/copyx"
var input DomainInput
if err := copyx.Copy(&input, req); err != nil { return err }
// 源与目标之间的指针、map、slice 需要隔离时:
snapshot, err := copyx.Clone(source)
if err != nil { return err }
```
默认浅拷贝,同名同类型字段自动赋值,保留零值;默认不会把 nil 填成非可空目标的零值。不要为使用工具新增一套重复模型。
需要重复使用或自定义规则时创建 Copier:
```go
copier, err := copyx.New(
copyx.WithDeepCopy(),
copyx.WithFieldNames[Input, View](map[string]string{"Name": "DisplayName"}),
copyx.WithConverter(func(v time.Time) (string, error) {
return v.UTC().Format(time.RFC3339), nil
}),
)
if err != nil { return err }
if err := copier.Copy(&view, input); err != nil { return err }
```
自定义函数的源/目标类型由 Go 泛型确定。深拷贝时返回原指针、原 map、子切片或嵌套旧引用都会报错;字符串/整数原值可以返回。差异规则、nil 策略、字段覆盖、资源限制和原 mapping 移除步骤见 [copyx 指南](COPY.md),完整类型及可运行代码见 [examples/copying](examples/copying/main.go)。工具使用运行时检查,类型对需测试;深拷贝不适用于连接、锁等资源。
### 数据库、存储及其他模块
生成项目在 `internal/svc` 中创建依赖,提供给 Logic/Repository,并用 `c.OnClose(db.Close)` 登记自有资源。生成的 main 在 HTTP 排空后关闭 svc,再关闭日志。直接使用框架的手写项目则可以用 `app.OnShutdown(db.Close)`;不要对同一资源重复登记。

# v0.19.0-preview(历史版本)
将可选结构转换改为直接 Go 调用,减少业务项目需要维护的配置。普通接口继续使用 `.api` 生成 DTO,不要求增加独立模型或任何拷贝规则。
- 新增只依赖标准库的 `copyx`:Copy、Clone、可复用 Copier;浅/深拷贝、严格字段覆盖、nil/零值策略、字段改名、忽略字段、精确类型 converter。没有全局注册和隐式数字强转。
- 深拷贝检查整个输入和输出图。自定义 converter 原样返回指针、map、slice,或新对象仍嵌套旧引用时返回错误;保留普通循环图,拒绝资源对象及超出遍历/估算分配预算的输入。
- 转换失败不提交部分目标;保留错误路径和原始错误链。并发复用只共享不可变类型元数据;源/目标读写和 converter 副作用由调用方负责。
- **不兼容变更:删除 mappings / mappingFiles、Go 类型加载与映射代码生成。** 检出旧配置/旧生成文件时给出迁移提示;不会静默删除业务正在使用的代码。公共字段组合、scalar、中间件工厂、Repository 选项保留。
- README 补齐当前能力入口、解释和用法,新增 [完整 copyx 指南](COPY.md)、[可运行示例](examples/copying);[AGENTS.md](AGENTS.md) 记录每次修改同步文档/示例/移除说明的约定。
```sh
go get git.yuntuo.hk/k2safe/go-omni@v0.19.0-preview
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.19.0-preview
# 如用过旧 mapping,先按 COPY.md 完成迁移:
go-omni api generate
go-omni api generate --check
go test ./...
```
迁移步骤和语义边界见 [copyx](COPY.md#从旧-mapping-迁移)。新工具做运行时检查,不能声称具备旧生成器的编译期字段覆盖保证;实际类型对必须有测试。独立三端工资示例验证金额精度、缺失/null/零值、空集合、错误链和字段新增;不修改或代替接入项目的完整业务回归。
46 个测试包的全量 race(含实际生成项目)、vet/build、Go 1.22 兼容测试通过;30 秒 fuzz 无失败,14 种基准场景各测量三轮。验收条件、性能数据及本轮未覆盖的外部环境见 [v0.19 验收记录](reports/copyxAcceptance.md)。本版仍为 preview。 空缓存远程 CLI 与 7 组真实生成消费者验收通过,无本地 replace;标签固定在 `fd83235ce7fc15ce88a482d385d70e61f25d7b32`,详见 [远程记录](reports/copyxRemote.json)。
---
以下是历史版本记录,其中 mapping 功能已在 v0.19 移除,不应继续作为当前接入方式。
# v0.18.0-preview(历史版本)
补齐可空嵌套映射和按模块拆分配置,减少重复转换代码,业务空值规则仍由项目显式选择:
- 嵌套 mapping 支持 `*S → *T` 保留 nil、`S → *T`,以及指定 nil zero/error 后的 `*S → T`;同样适用于 slice/等长数组元素。错误保留字段路径、索引和内部错误链,失败不返回部分结果。
- `mappingFiles` 显式引用项目内的映射文件,支持跨文件向前引用;统一检查重名、循环、类型与字段覆盖。禁止多层导入、路径越界和隐式覆盖,生成期间核对全部配置输入。
- 同类型 `*T → T` 可显式配置 nil zero/error;现有 converter 保持完整控制,不默认放宽类型或混入领域规则。
- `pointerResult: true` 额外生成 `<Name>Ptr(S) (*T,error)`,原值函数保留;失败返回 nil 与原错误,辅助函数名冲突在生成前拒绝。
```sh
go get git.yuntuo.hk/k2safe/go-omni@v0.18.0-preview
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.18.0-preview
go-omni api generate
go-omni api generate --check
go test ./...
```
v0.17 的单文件 mappings、现有 converter 和业务文件继续保留。配置拆分时移动完整映射条目,主配置显式列出子文件;不保留重复定义。新能力均为可选生成配置,不增加运行时依赖。nil zero 表示 Go 零值并跳过子映射;业务必填、金额精度、编号格式和快照复制仍由项目负责。
使用与迁移见 [生成能力指南](GENERATION.md),回归和发布后验收见 [验收记录](reports/nullableMappingAcceptance.md)。本版仍为 preview。
全量 44 个测试包的 race、vet、build 和实际进程验收通过;空缓存远程 CLI 与 8 组实际生成消费者回归也通过,同版依赖且无本地 replace。标签固定在 `4563a6354fac19f22cd8d407fd76d98b8cc9c406`。
---
# v0.17.0-preview(历史版本)
减少项目里的重复声明、字段赋值和中间件装配代码,业务规则继续由项目控制:
- `.api` 公共字段组合:保持 JSON 平铺,DTO、绑定、校验和 OpenAPI 同步;字段冲突、循环和超限明确报错。
- 可选结构映射:在 `omni.gen.json` 显式声明源与目标,生成编译期检查的普通 Go 赋值。不同字段名、金额、时间和指针转换由项目指定函数;遗漏字段与类型错误在写文件前失败。不使用 JSON 往返或运行时反射。
- 带依赖的中间件工厂:svc 初始化依赖后自动调用 `New<Name>(deps)` 并注册;错误、nil 或 panic 阻止启动,已登记资源按生命周期清理。
- Repository 骨架默认关闭,可按 group 启用;已有业务文件始终保留。生成选项与映射纳入重新生成和 `--check`。
```sh
go get git.yuntuo.hk/k2safe/go-omni@v0.17.0-preview
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.17.0-preview
go-omni api generate
go-omni api generate --check
go test ./...
```
新项目默认使用 factories;已有项目首次升级保留 handlers 模式,需要显式迁移后再切换。映射按需开启,先准备业务类型、转换函数和依赖,再声明映射;普通引用赋值保留 Go 语义,缺失/null 语义由项目类型与转换函数定义。
使用方法、文件归属和升级步骤见 [生成能力指南](GENERATION.md),回归与发布验收见 [验收记录](reports/generationExperienceAcceptance.md)。本版仍为 preview;框架验收不等于业务项目完成迁移。
全量 44 个测试包的 race、vet、build 和实际进程验收通过;发布后的空缓存远程 CLI 与 7 组生成消费者回归也通过,同版依赖且无本地 replace。标签固定在 `8b588a24cd653dac77dd68f6777e0db367981f19`。
---
# v0.16.0-preview(历史版本)
补齐通用契约与生成体验,业务响应协议继续由项目定义:
- `returns([]string/[]int64/[]bool/[]any)` 及其他支持的基础类型数组,贯通 Logic、Handler、OpenAPI 和生成检查。nil 根数组输出 `[]`;DTO 数组、nullable、null、raw 和 204 保持原语义。字节数组明确拒绝 base64/数组歧义。
- OpenAPI 以标准 components / `$ref` 共享重复响应、schema、示例;保留同一 HTTP 200 下的成功与失败、模板参数、数字业务码和 data:null。
- workspace 显式配置 Go Catalog 提供方,一次导出共享 JSON,多服务通过受控根引用。支持服务/路由的文档错误列表,运行期 App 目录继承不变。check 核对导出漂移并保持项目文件不变。
- EnvOptions.Aliases + ServerEnvAliases 统一完整配置与框架短名称的 Lookup、类型转换、空值规则。完整名称优先,显式空值不等于未设置;旧 ApplyEnv 的空值/逗号列表行为保留。
```sh
go get git.yuntuo.hk/k2safe/go-omni@v0.16.0-preview
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.16.0-preview
go-omni api generate
go-omni api generate --check
go test ./...
```
旧项目 config/Logic/svc 继续由开发者维护,不会被重新生成覆盖。已有环境配置需按 [一次覆盖完整配置](DEVELOPMENT.md#一次覆盖完整配置与-http日志短名称) 合并 OverlayEnv 与 ApplyEnv;共享错误目录接入见 [workspace 配置](DEVELOPMENT.md#同一份-go-错误目录供多个服务生成)。已有手写权限 Handler 切换自动生成前,先迁出实现并显式移除 Manual 文件,生成器不会静默删除。
全量 race(含实际生成消费者)、vet、build、根入口/退出/再生成验证通过。eTax 只读契约验收:API 文档 20,751,149 → 847,171 字节,ID 文档 1,008,210 → 392,481 字节;70 个操作展开引用后与原文档完全一致。空缓存远程 CLI / 固定版本消费者验收也已通过,没有本地 replace;标签固定在 `64e3bd6cfced225476d58e95037249cd0a4fe695`。详见 [验收记录](reports/contractFollowupAcceptance.md)。这不代表已完成业务项目迁移。
---
# v0.15.0-preview(历史版本)
增加通用后台分阶段关闭:生成入口先完成 HTTP 排空,再运行全部 OnStop、全部 OnDrain,确认组件收尾后逆序释放 OnClose 资源,最后关闭日志。适用于任意后台组件;不引入 Orbit,不改变业务事务或任务一致性策略。
- svc 登记成对、同名的 OnStop/OnDrain,Context 用于早期退出通知,WorkContext 供已接受工作在收尾期间使用。同一阶段并发执行,存在内部先后依赖的组件组合登记。
- server.lifecycle 配置 stopTimeout、drainTimeout、cancelTimeout。阶段超时取消工作并给未返回钩子收尾窗口;错误与阶段/组件名称可通过错误链追踪。
- 不能确认后台已经结束时,返回 ErrResourcesRetained,保留共享资源和借用日志,生成进程非零退出。未返回的 Stop 不会与自己的 Drain 重叠;错误、panic 不阻止其他组件尝试收尾。
- task.Runner 增加 StopAccepting/Wait,原 Shutdown/Close 继续可用。核心 lifecycle 不依赖 task 或其他适配器。
- 初始化和监听失败复用同一流程;重复关闭只执行一次。生成器继续保留配置、svc 和业务代码。
```sh
go get git.yuntuo.hk/k2safe/go-omni@v0.15.0-preview
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.15.0-preview
go-omni api generate
go-omni api generate --check
go test ./...
```
v0.14.x 无需重写 svc/config;生成器更新 main/runtimeGen,未配置时使用默认时限。也可 api upgrade --dry-run/--apply 更新依赖与生成文件,保留已有项目扩展。需要阶段保证的旧后台 OnClose 登记,应显式迁到 Stop/Drain;v0.13 及更早版本仍按原迁移指南处理。
全量 race(含实际生成项目)、vet、build 和隔离 MySQL/GORM 验收已通过。发布后的空缓存远程生成项目与真实 MySQL/GORM 验收也通过,CLI/框架同版且无本地 replace;标签固定在 `16deead70e860052c5b629511207578c03f9b2cb`。详见 [生命周期接入](lifecycle/README.md#后台组件分阶段关闭) 与 [验收记录](reports/phasedLifecycleAcceptance.md)。Go 无法强制结束任意 goroutine;OnClose 仍须能返回,HTTP 处理器仍须响应取消。此版不会将未知的第三方组件自动改造成优雅关闭组件。
---
# v0.14.1-preview(历史版本)
增加可选 `database/gormx`:GORM 复用 go-omni 已初始化的标准池、TLS、限额、健康检查和关闭流程,业务继续使用原生 GORM 模型与事务。核心 App/数据库包的编译依赖链不引入 GORM。
在 svc.Init 中调用 `gormx.MySQL(ctx, c.DB, gormx.WithLogger(c.Logger))`;通用 Open 工厂保留其他方言入口。适配器保护借用池不被初始化失败路径关闭,并为初始化查询设置时限。查询使用 WithContext,SQL 日志接入 logx,请求标识、慢查询和错误分类贯通;默认不输出绑定参数与驱动完整错误文本。
v0.14.0 项目更新 module 与 CLI 即可,不改生成目录或 main。模板最低运行时保持 v0.14.0;修正新版 CLI 把最低兼容版本误当自身版本、导致同版消费者出现版本提示的问题。其他数据库方言和管理额外池的插件未纳入本次实库验收,原生 PrepareStmt 的生命周期限制见 [接入说明](database/gormx/README.md)。
```sh
go get git.yuntuo.hk/k2safe/go-omni@v0.14.1-preview
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.14.1-preview
```
全量 race(含生成消费者)、vet、build,以及隔离 MySQL 的事务/取消/日志/生成项目接入通过。发布后的空缓存远程 MySQL/GORM 和生成项目验收均通过,无本地 replace,CLI 与框架使用同版。标签固定在 `b8ab6b35219d53d6de392c920fe7ecbe9a76dade`,详见 [GORM 验收](reports/gormAcceptance.md)。
---
# v0.14.0-preview(历史版本)
本版补齐契约驱动的业务开发与通用基础设施。项目继续维护接口、配置、依赖装配、Logic、SQL 和业务规则;生成器维护入口、请求绑定、路由、响应与文档。
## 安装与升级
```sh
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.14.0-preview
go-omni new --module example.com/billing ./billing
```
新生成器与运行时一起升级。已有 v0.13 项目先运行 `go-omni api upgrade --dry-run`,再按 [定点迁移步骤](DEVELOPMENT.md#v013-项目升级) 处理;不会静默覆盖自定义 svc/config。运行期的新构造器由生成器维护,项目初始化迁入 `svc.Init`,使用 `OnClose` 登记资源。
## 本版能力
- `.api` 支持根数组、可空对象、成功 null;真正 204 独立保留。生成 Logic、Handler、OpenAPI 和漂移检查使用相同语义。
- 请求契约控制未知 query、原始 UTF-8、charset、必须/可选/禁止 body 和严格空对象。路由覆盖 App 策略,普通 JSON 只解析一次。
- multipart 声明文件、文本和 JSON 表单字段。Logic 收到校验后的 DTO;文件有界暂存、流式读取、请求结束清理,保留底层 raw/multipart/下载扩展。
- 完整项目配置支持环境覆盖、显式零值、空值策略、必填、嵌套及复杂类型。独立校验先于日志和连接创建。
- `lifecycle.Runtime` 统一逆序清理、幂等关闭、失败回滚及故障保留;App Logger 独立,支持标准 `log.Logger` 与可信请求元数据。提供依赖中间件装配示例和可选 context 错误映射。
- 官方 `database/mysql` 适配器提供结构化配置、每连接池独立 TLS/mTLS、驱动日志、启动检查与失败清理。继续返回同一 `database.DB`,不自动迁移表或重试业务事务。
- 字段注释、示例和枚举说明进入 DTO/OpenAPI;`api format` 幂等格式化。Go 错误目录可显式导出供文档使用,无需复制错误定义。
- 显式共享契约 roots、来源摘要、分文件 DTO、多服务 workspace 命令、基础模板升级预览;保留目录边界及业务文件所有权。
详见 [业务开发指南](DEVELOPMENT.md)、[数据库接入](database/mysql/README.md) 和 [验收记录](reports/businessDevelopmentAcceptance.md)。
全量 race(含生成项目)、vet、build 与本地进程验收通过。发布后的空缓存远程消费者和隔离 MySQL 验收也均通过;CLI/框架同版且无本地 replace。标签固定在 `f5478cdc7662704b164637649305361e52f7c598`,报告单独提交。
仍需业务维护:契约、配置、svc 依赖创建/探针/清理登记、错误目录、Logic、Repository 和权限中间件。特殊协议可使用保留的扩展点。声明式上传的暂存磁盘和并发量需配置容量;共享契约版本标签由项目管理,框架校验摘要但不下载依赖。此版仍为 preview,不代表 eTax/ePay 已完成业务迁移。
---
# v0.13.0-preview(历史版本)
本版补齐项目依赖主动退出与内置接口配置。ID 租约、数据库或后台任务等故障由项目判断,框架通过统一生命周期完成退出;不内置业务规则。
## 使用与升级
```sh
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.13.0-preview
# 在业务 module 中执行
go get git.yuntuo.hk/k2safe/go-omni@v0.13.0-preview
go-omni api generate
```
新项目自动获得全部扩展。v0.12 的 config/svc 属于项目文件,重新生成会保留它们;需按 [升级步骤](PROJECT.md#从-v012-生成项目升级) 给 svc 补入 Lifecycle、RequestShutdown 与清理衔接,main 和 Handler 由生成器更新。旧 v0.11 目录仍按原迁移规则在新目录生成。
## 行为
- `svc.RequestShutdown(err)` 非阻塞通知:停止接收请求、排空、关闭依赖和日志。首个非空故障保留,故障退出码为 1;正常停止在没有其他故障时退出码为 0。初始化期间通知、并发通知和排空期间报告故障均可处理。
- App 生命周期入口保留异常 context 取消原因;符合 context.Canceled 的信号取消保持正常停止。生成入口还读取 Controller.Err,保留显式依赖故障,即使该故障包装了 context.Canceled。
- `/health/ready` 修复绕过响应配置的问题,默认与 liveness 一起使用项目 App 的响应格式。就绪成功使用项目成功码与提示;未就绪使用 `NOT_READY` 的项目错误定义,同时固定 HTTP 503。raw 模式只返回健康数据;内部探针原因仅供日志。
- `server.endpoints` 控制三个内置 GET 接口的开关和路径,健康端点另有 responseMode。支持环境变量覆盖。OpenAPI 保持原始规范,不包业务公共体;关闭 HTTP 端点不影响生成文档。
- `.api` 不再固定保留三个默认路径;启用的内置路径与业务 GET/参数/通配路由重叠时,启动前返回明确错误并清理已创建的依赖。关闭或改名后允许项目接管旧路径。全局中间件继续执行。
## 验收
源码测试和实际生成项目验证记录见 [生命周期与端点验收](performance/lifecycleEndpointsAcceptance.md)。复验命令:
```sh

# go-omni CLI
v0.19 移除结构映射生成:`omni.gen.json` 只保留 Repository 和中间件选项。普通接口直接使用生成 DTO;需要类型转换时用普通 Go 或可选 [copyx](../../COPY.md)。旧 `mappings` / `mappingFiles` 必须按迁移步骤清理,CLI 不会静默删除仍在调用的旧生成文件。
公共字段组合、中间件工厂和按需 Repository 继续支持,见 [生成能力指南](../../GENERATION.md)。
v0.16 增加基础类型/动态 JSON 数组返回、OpenAPI 公共引用和 workspace Go Catalog 统一导出。见 [接入与筛选规则](../../DEVELOPMENT.md#同一份-go-错误目录供多个服务生成)。
v0.14 新增 `api format [--check]`、`api upgrade [--dry-run|--preview <空目录>|--apply]`,以及 `workspace format|generate|check --file omni.workspace.json`。详见 [通用开发指南](../../DEVELOPMENT.md)。
新项目采用根目录 `main.go` 与 `internal/config、svc、logic、handler、types`。完整职责、启动扩展、流式接口和生成文件边界见 [项目指南](../../PROJECT.md)。

Generated svc.New receives Config and a borrowed Logger. Add dependencies in svc.Init,
then immediately register each cleanup with OnClose. A later initialization failure
runs registered cleanups in reverse order. Close is idempotent. GlobalMiddleware

once before route registration; logging is configured earlier through Config.
The generated main runs HTTP draining before closing svc resources, then the logger.
The generated main runs HTTP draining, all OnStop hooks, all OnDrain hooks, resource
OnClose callbacks, then logger close. Stop/drain hooks within a phase run concurrently;
combine components with ordering dependencies into one pair. Pair OnStop/OnDrain
with the same name. OnDrain returns nil only after final work and acknowledgements
have finished. Use WorkContext for accepted background work; Context is an early
shutdown notification. server.lifecycle configures stopTimeout (5s), drainTimeout
(10s), and cancelTimeout (5s grace per timed-out phase). Zero uses defaults.
Timeout/failure cancels WorkContext. If hooks cannot prove completion, resources
and the borrowed logger are retained and the generated process exits unsuccessfully.
Errors retain their causes. No automatic retry of close or force killing of goroutines.
Do not close borrowed resources or attach duplicate cleanup hooks to App. The startup
context cancels on signals; long-lived clients/workers that requests depend on need
their own lifetime, canceled by OnClose after HTTP draining.
svc.RequestShutdown(err) lets a dependency report a fatal service failure.
It returns immediately. Generated main stops accepting requests, drains them,
closes dependencies and logs, then exits nonzero with the original cause.
nil requests a normal stop. Concurrent calls keep the first non-nil failure;
notifications during initialization or draining are retained. Close must stop
and join project-owned monitors before the final shutdown result is returned.
The svc lifecycle context signals draining, not permission to close resources
still used by active requests. Liveness and readiness are different: shutdown
makes readiness 503; it does not turn a running process's liveness into failure.
