- 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。
- 2026-09-26 用户决定:配置文件显式声明固定值或 `${NAME}` / `${NAME:-fallback}`,旧自动环境覆盖、前缀/别名及 env/envDefault 标签模式移除,不得重新引入隐式二次覆盖。项目维护 Config/Default/Validate/文件,生成器维护 Load/main。

# 配置:文件明确声明值的来源
v0.22 起只使用这一条流程:
```text
项目 Default() → 解析选中的一个文件 → 解析字段值中的环境引用
→ 按 Go 类型绑定已提供的字段 → 项目 Validate() → 初始化日志和依赖
```
没有环境前缀、别名表或隐式二次覆盖。业务只维护 `Config`、`Default()`、`Validate()` 和配置文件。项目 Validate 中继续调用嵌套框架配置的 Validate;生成模板已包含这些调用。验证函数只检查值,不应打开资源。
## 直接使用
```go
type Config struct {
Server omniConfig.Config `json:"server"`
BatchSize int `json:"batchSize"`
Enabled bool `json:"enabled"`
Password string `json:"password"`
Timeout time.Duration `json:"timeout"`
}
func Default() Config {
return Config{Server: omniConfig.Default(), BatchSize: 100, Enabled: true,
Timeout: 3*time.Second}
}
func (c Config) Validate() error {
if err := c.Server.Validate(); err != nil {
return omniConfig.AtField("server", err)
}
if c.BatchSize < 0 { return omniConfig.Invalid("batchSize", "must not be negative") }
return nil
}
// 手写项目;生成项目的 Load 已自动调用此入口。
cfg, err := omniConfig.LoadProject("etc/config.yaml", Default())
```
```yaml
server:
address: "${HTTP_ADDR:-127.0.0.1:8080}"
password: "${DB_PASSWORD}"
timeout: "${REQUEST_TIMEOUT:-3s}"
enabled: false
```
文件未写 batchSize,保留 100;enabled 明确写 false,就使用 false。变量名字完全由文件决定,不需要对应 Go 字段名。配置文件可只列出部署需要变动的字段;不会自动导出/打印包含凭据的完整配置。
## 引用语法
| 文件里的值 | 含义 |
| --- | --- |
| `host: 127.0.0.1` | 固定值,不读取任何环境变量 |
| `password: "${DB_PASSWORD}"` | 未设置或空字符串报错,不回退到 Default() |
| `port: "${DB_PORT:-3306}"` | 未设置或为空时使用 3306 |
| `sessionToken: "${SESSION_TOKEN:-}"` | 未设置或为空时使用空字符串,是否合法由目标类型和 Validate 决定 |
| `url: "https://${HOST}:${PORT:-443}/v1"` | 普通字符串中可出现多个引用 |
| `literal: "$${DB_PASSWORD}"` | 得到字面量 `${DB_PASSWORD}`,不读取变量 |
| `literal: "$$cost"` | `$$` 转义一个 `$`,得到 `$cost` |
变量名遵循 `[A-Za-z_][A-Za-z0-9_]*`。只支持 `${NAME}`、`${NAME:-fallback}` 和 `$$` 转义,不支持 `${NAME-default}`、嵌套引用或 shell 表达式。普通单独的 `$` 保留。fallback 到第一个 `}` 结束,可包含冒号、`:-`、引号等文件格式允许的字符;需要包含 `}` 的值可使用固定值或环境变量。
解析只扫描文件的**已解码字段值**,不替换 YAML/JSON/XML 源文本,不扩展字段名,也不扫描 Default() 的字符串。插入的环境值和 fallback 不再展开。密码 `DDSFLKJlsf:saf:-123`、引号、换行、`${OTHER}` 均原样保留,不破坏文档结构。字符串不统一 TrimSpace;`"0"`、`"false"` 和全空格字符串均属于已提供。
同一变量每次加载最多读取一次;下一次加载会重新读取。没有全局变量值缓存。并发加载各自维护结果,不能把调用者正在修改的默认配置当作共享可变输入。
## 类型与覆盖
目标 Go 类型决定引用结果的转换:整数、浮点数、布尔值、`time.Duration`、字符串、指针及已有自定义 JSON/Text 反序列化。数值范围按目标位宽检查,整数不经过 float64。自定义反序列化仍由自定义类型解释文本,不猜测其业务含义。
- 文件缺失字段保留初始值;显式 0、false、空字符串正常覆盖,不用零值判断字段是否存在。
- `${MISSING}` 失败就报错;需要备用值必须写 `${MISSING:-value}`。
- 字符串编号 `"001"` 保持 `001`;绑定到 int 才转整数。环境里的 `null` 不自动变成空指针,`[1,2]` 不自动变成数组。
- 集合直接在文件里声明,可在每个标量元素中使用引用,例如 `ports: ["${PORT_A:-8080}", "${PORT_B:-8081}"]`。
- 数组整体替换;空 slice 保持非 nil;固定长度 Go 数组要求长度一致。map 合并键,已提供键的值整体替换。
- 固定文件 null 沿用 JSON 语义:清空指针/map/slice/interface,普通值字段保持初始值。需要区分 null 时使用指针。
- `any` 的引用结果保持字符串,不猜测动态类型。固定 JSON/YAML 数字使用 json.Number 保留精度。
- 引用成功后的值不会再覆盖一次。旧 `GO_OMNI_*` 名称只有出现在文件引用中才有作用;不隐式重置日志 file/rotation。
普通固定字符串仍按原有严格绑定规则处理;不会为了支持变量,把所有 `"123"` 都自动转换成数字。
## YAML、JSON、XML 一致
使用 Go 的 `json` 字段名,无需维护三份 tag。以下三份文件等价:
```yaml
port: "${PORT:-3306}"
password: "${PASSWORD}"
```
```json
{"port":"${PORT:-3306}","password":"${PASSWORD}"}
```
```xml
<config><port>${PORT:-3306}</port><password>${PASSWORD}</password></config>
```
XML 使用 `<config>` 根,标量占位符写在普通叶元素或 `type="string"` 元素中,由 Go 字段决定类型;显式 `type="number"` / `type="bool"` 表示文件里已经有合法数字/布尔常量。XML 数组用 `type="array"` 加 `<item>`;空对象 `type="object"`、null 用 `type="null"`。不从重复元素猜测数组。
`.api` 不经过配置加载器,响应模板 `${code}` 不变。**如果把响应模板写在 YAML/JSON/XML 配置文件里,须转义:**
```yaml
server:
response:
body:
code: "$${code}"
msg: "$${message}"
data: "$${data}"
```
加载后恢复为 `${code}` 等响应占位符,仍由响应编码器处理。
## 生成项目与检查
| 文件 | 维护方 |
| --- | --- |
| `main.go`、`internal/config/loadGen.go` | 生成器维护,纳入 `generate --check` |
| `internal/config/config.go` | 项目维护 Config、Default、Validate |
| `etc/config.yaml` 等选定文件 | 项目维护,重新生成不覆盖 |
| `internal/config/loader.go` | 初次生成即可使用,仅添加自定义格式时才修改 |
```sh
go run . -config etc/config.test.yaml -check-config
go run . -config etc/config.local.yaml
go build .
go-omni api generate --check
```
`-check-config` 使用与启动完全相同的 Load,通过时退出 0、失败时非零;不打印配置,不创建日志文件、数据库、后台组件或 HTTP 监听。它只校验配置,不检测真实数据库连接或证书握手。
`-config` 只选一个文件,不自动叠加 local/test/default。指定文件不存在时报错;`-config ''` 只使用 Default() 后校验,不读取任何环境变量,也不寻找其他文件。示例:[examples/configuration](examples/configuration/README.md)。
## 安全诊断与限制
```text
config "etc/config.yaml":7:9 env "DB_PORT" field "database.port": expected a valid int
```
`*config.Error` 包含 File/Field/Env/Line/Column/Reason。引用错误同时保留文件与环境变量名;组合引用失败可列出多个名字。行列定位原文件字段,不把环境值伪装成源文件文本。无法取得位置时仍提供可用的文件/字段信息。
用 `config.Invalid(field, publicReason)` 或 `config.AtField(prefix, err)` 报业务校验错误。未知字段给出唯一且接近的已声明字段建议,不自动修改。错误默认不打印原值;自定义 Reason 不应拼入秘密值。原始 cause 仍支持 errors.Is/As,不要把 Unwrap 后的错误或整个配置写到日志。
文件最多 1 MiB;单个环境值/展开字段最多 1 MiB,展开字符串合计/变量缓存分别最多 4 MiB;解析/展开限制 64 层、100000 个节点与引用计数。拒绝无效 UTF-8、多文档、重复字段、未知字段、非普通文件;YAML 不接受 alias/merge/custom tag,XML 不接受 DTD/外部实体。不执行 shell,不自动加载 `.env`。
## 框架模块的字段诊断
v0.23 起 MySQL(含连接池/TLS)、通用数据库池、日志(含轮转/时区)、HTTP 客户端、退出阶段和请求策略返回字段级安全原因。沿用项目已有的 `config.AtField("database", err)` / `config.AtField("server", err)`,自动组合嵌套字段,不需业务重复校验基础参数。
例如文件中 `database.port: "${DB_PORT}"` 的引用值为 70000:
```text
config "etc/config.yaml":3:9 env "DB_PORT" field "database.port": must be between 1 and 65535
```
日志级别非法指向 `server.log.level`;池参数指向 `database.pool.maxIdleConns` / `pingTimeout`。框架只公开已定义的安全原因,第三方/项目普通 error 仍显示 validation failed 并保留 errors.Is/As 原因链;业务使用 Invalid/AtField 提供公开原因。不要解析错误字符串;使用 `*config.Error` 字段。未提供字段的位置可能不可用,字段与原因仍保留。
生成项目现有 Load 和 `-check-config` 自动获得这些诊断。日志可在 `server.log.timeZone` 配置 IANA 名称,见 [实例时区](logx/README.md#实例时区)。
## 可选解析器与测试来源
内置格式无需项目手写加载器。需要额外格式时在已有 NewLoader 注册 Decoder,后续仍自动经过同一引用/绑定/校验流程:
```go
func NewLoader() (*omniConfig.Loader, error) {
return omniConfig.NewLoader(
omniConfig.WithDecoder("custom", omniConfig.JSONDecoder{}),
)
}
```
Decoder 返回 Document(map/string/bool/json.Number/nil/[]any,XML 类标量可用 Text),可提供 Positions。实例注册无全局 init;插件必须可并发调用、不修改共享输入,并且是可信 Go 代码。
测试或嵌入宿主可以用 `WithLookupEnv(func(string)(string,bool))` 替换引用查找函数。它仍然只读取文件明确引用的名称,不启用任何自动覆盖。普通业务不需要这个选项。
## v0.22 迁移:旧模式已移除
这是不兼容调整,不保留两套加载逻辑:
- 删除 `EnvOptions`、`LoadFromEnv`、`ApplyEnv`、`OverlayEnv`、`ApplyDefaults`、`ServerEnvAliases` 和 `env`/`envDefault` 标签处理;检出遗留标签会提示迁移。
- 删除 `database.ConfigFromEnv` / `database.ApplyEnv`;数据库配置作为项目 Config 的字段绑定。DSN 字段可在文件里使用 `dsn: "${DB_DSN}"`,序列化 database.Config 不输出 DSN 原值。
- `LoadProject(path, defaults[, loader])` 不再接收 EnvOptions;`LoadFile(path)`、`NewReloader(path, logger)` 不再接收前缀。
- `omni.LoadConfig(path)` 的参数现在是文件路径;空路径只用框架默认值。
迁移顺序:
1. 将 envDefault 默认值搬入 Default(),移除 env/envDefault 标签。需要文件绑定的旧 `json:"-"` 密钥字段改成明确 json 名称;不打印配置对象。
2. 按实际部署需要,在选定文件写环境引用。固定值保持固定,不按原前缀猜测。原先依赖环境切换日志输出的项目,应在文件明确配置 file/output/rotation。
3. 配置文件中的其他 `${...}` 模板改成 `$${...}` 字面量;`.api` 无需修改。
4. 手写项目改为 LoadProject。生成项目保留 Config/Default/Validate/NewLoader,删除旧手写 Load 后重新生成;main/loadGen 由生成器更新,业务配置文件不会被静默改写。
5. 升级匹配的 CLI 与框架,执行 generate、generate --check、go test、go build 和 `-check-config`,再使用真实部署配置启动。
低层 `DecodeFile(path, defaults[, loader])` 也解析显式引用,但不调用 Validate;默认值和原始 Document 都不会因失败而被部分修改。日志 Reloader 仍只允许 log.level 变化,其他静态字段变更要求重启。
## 国际化配置
通用国际化的 `i18n.Config` 可作为项目配置的字段显式加载并调用 Validate。正文词典使用 `i18n.LoadFS` / `DecodeJSON`,不经过环境引用展开。构建 Bundle 后通过 `WithLanguagePolicy` / `WithErrorLocalizer` 装配借用的只读实例;没有隐式环境变量或全局当前语言。见 [国际化指南](i18n/README.md) 和 [完整示例](examples/i18n/README.md)。
## 跨域配置
生成项目的 `server.cors` 由本加载流程直接绑定、校验并交给 App,不需要修改生成入口。支持固定来源数组或元素内显式环境引用;非法来源定位具体数组元素。默认关闭,完整配置与行为见 [CORS 指南](cors/README.md)。

# 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。
## 类型预检
v0.23 新增可选预检,无需填写映射文件或构造测试值:
```go
// 参数方向是源 → 目标;与 Copy 使用同一组选项。
if err := copyx.Check[Request, BusinessInput](options...); err != nil {
return err
}
// 复用已有 Copier:传结果类型,不添加 Copy 所需的额外输出指针。
err := copier.Check(reflect.TypeFor[Request](), reflect.TypeFor[BusinessInput]())
```
适合 CI 测试或初始化检查;这是程序执行的类型检查,不是 Go 编译器自动证明。递归检查切片/数组元素、map 键值、指针、嵌套字段、改名、忽略和严格覆盖;用已访问类型对处理递归结构。不执行 converter,也不调用构造器,不读取实例值。错误路径如 `$.Rows[].Value: copyx: incompatible types: string -> int`。
Check 复用 Copy 的规则,包括浅拷贝对同类型容器的直接赋值:这种情况下内部 converter 不会自动逐项执行。需要处理内部字段时选择深拷贝或容器 converter。
- 未知具体值的源 interface 需要运行时验证;无法静态判定时返回 `ErrDynamicType`。项目可给该接口类型对提供精确 converter 并承担内容验证。
- 已注册 converter 的签名被接受,但函数不在 Check 中执行;其返回错误、panic、金额规则不能靠预检证明。
- nil 到非可空目标、map 键转换碰撞、深拷贝结果是否残留源引用继续在 Copy 时检查。Check 成功不会关闭这些保护。
- 实际 Copy 也修正了空集合的检查缺口:确定的嵌套类型不匹配不再因为切片/map 为空或数组长度为 0 而通过。需要这些转换时提供显式 converter;目标仍只在整体成功后更新。
- 不引入全局配置、映射语言或业务类型;Copier.Check 可并发调用,不共享每次检查的遍历状态。
示例:[developerTools](examples/developerTools/README.md)。普通同名同类型字段不需要额外配置。
## 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。

## 完整业务配置的环境覆盖
## 文件声明配置来源
生成项目默认执行:代码与 `envDefault` 默认值 → JSON/YAML 文件 → 全结构体环境覆盖 → 既有框架环境别名 → `Validate`。增加业务字段不需要另外写 `os.Getenv`。
项目维护 Config、Default()、Validate() 和配置文件;生成器维护 Load/main。流程为默认值→选定文件→显式 `${NAME}` / `${NAME:-fallback}` 引用→类型绑定→校验。没有前缀、别名或 env/envDefault 隐式覆盖。
```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"`
}
```
固定值保持固定,缺失字段保留 Default(),0/false/空字符串正常覆盖;引用失败不回退初始化默认值。`$$` 转义 `$`,字符串凭据保留空格与特殊字符。
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。
`go run . -config etc/config.test.yaml -check-config` 只校验,不打开日志、数据库或端口。生成/check/dry-run 保留业务文件;新的模板要求 v0.22。完整格式、错误定位、解析器与移除清单见 [CONFIG.md](CONFIG.md)。

## 可选结构映射
## DTO 与业务类型
`.api` 生成 DTO,业务独立维护输入/结果类型。项目明确选择需要自动赋值的类型对;不从数据库反向生成公开接口,不自动推断反向映射。
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。
假设 `types.AdminRequest` 有 `Name string`、`Salary amount.Money`、`CompanyID string`,业务的 `domain.EmployeeInput` 有 `EmployeeName string` 和同类型 `Salary`:
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。
```json
{
"repository": "none",
"middleware": "factories",
"mappings": [
{
"name": "ToEmployeeInput",
"source": {"package": "example.com/payroll/internal/types", "type": "AdminRequest"},
"target": {"package": "example.com/payroll/internal/domain", "type": "EmployeeInput"},
"fields": {
"EmployeeName": {"source": "Name"}
},
"ignoreSource": {
"CompanyID": "由 Logic 单独做企业范围授权,不属于请求体输入"
}
}
]
}
```
执行 `go-omni api generate` 后,产生独立的生成文件 `internal/mapping/mappingsGen.go`:
```go
func ToEmployeeInput(source types.AdminRequest) (domain.EmployeeInput, error) {
var result domain.EmployeeInput
result.EmployeeName = source.Name
result.Salary = source.Salary
return result, nil
}
```
包别名由生成器决定。业务调用 `mapping.ToEmployeeInput(*req)`;反向响应映射按另一条 source/target 规则声明。两个类型完全相同时通常无需映射。
### 类型与覆盖检查
自动赋值要求同名且 **Go 类型一致**(类型别名按 Go 类型系统处理),字段名使用 Go 名称,不按 JSON 标签猜对应关系。int32 → int64、`*Money` → Money、数值 ID → string 都必须显式转换。不会暗中补零、解引用或执行数字强转。
每个源字段必须被使用或出现在 `ignoreSource`;每个目标字段必须被赋值或出现在 `ignoreTarget`。忽略规则必须给出非空原因,目标忽略明确意味着保留零值;规则引用不存在的字段也会失败。新字段若无法自动匹配,会在生成阶段报错。两边同时添加的同名同类型字段会自动加入生成代码,`--check` 检出未重新生成的差异。
根类型是项目可导入的具名结构;支持值类型匿名嵌入,规则可用 `Employee.EmployeeName` 这样的实际 Go 字段路径。同名提升歧义、未导出字段和匿名指针嵌入拒绝处理。普通具名嵌套字段使用独立映射或转换函数,不猜测内部结构。泛型声明不能直接作为根;具体字段类型按 Go 类型系统检查。
配置变化、遗漏映射、类型错误会在写入前失败。映射生成与其他生成产物使用同一套文件所有权机制;手改映射生成文件会被拒绝覆盖。
### 显式转换函数
```json
"fields": {
"Salary": {
"source": "Salary",
"convert": {"package": "example.com/payroll/internal/convert", "name": "SalaryValue"}
}
}
```
支持这两种精确签名:
```go
func SalaryValue(source *amount.Money) amount.Money
func SalaryValue(source *amount.Money) (amount.Money, error)
```
项目选择一种实现。nil、默认值、金额精度、日期格式和错误码由函数负责;若两边已经是同一个 Money 类型,无需再次解析或序列化。转换函数应仅负责值转换,不执行 SQL 或改变授权范围。
错误通过 `%w` 加上映射名/目标字段路径,保留 `errors.Is/As` 和框架错误链;返回零目标值,不交付部分完成的结果。包装不主动添加源值或转换后的值。错误是否公开仍由项目错误目录和响应策略决定。
### 嵌套对象、数组与引用
`mapping` 指向同配置中的另一条映射,`elements` 明确要求逐项映射:
```json
"fields": {
"Summary": {"source": "Summary", "mapping": "ToSummary"},
"Items": {"source": "Items", "mapping": "ToItem", "elements": true}
}
```
`mapping` 与 `convert` 互斥。`elements` 可以配合其中任意一种,也可以对类型相同的元素直接赋值;支持 slice→slice、等长 array→array,禁止隐式互转。nil slice 保持 nil,非 nil 空 slice 保持非 nil,逐项失败的错误包含索引,循环映射声明被拒绝。
未选择 elements 的同类型指针、map、slice 使用普通 Go 赋值,**共享引用**,不做隐式深拷贝。elements 会分配新的目标 slice,但元素内的引用仍遵循其映射规则。需要深拷贝时显式提供转换函数。
映射不保存原 JSON 的字段存在信息。普通 `*T` 在绑定后可能已把缺失和 null 合并为 nil;无法在转换阶段恢复区分。有三态需要的项目必须先使用能携带该信息的输入类型及绑定扩展;没有声明三态时,保持当前输入类型的语义。完整表单更新和局部更新由业务决定,框架不把 nil 自动解释成“保留旧值”。
### 生成顺序与 CI
1. 先从 `.api` 生成项目,添加业务结构、scalar 和转换函数,执行 `go mod tidy`。
2. 在 `omni.gen.json` 列出映射,执行 `go-omni api generate`。
3. Logic 调用生成函数。后续改字段后重复生成,不修改 `*Gen.go`。
4. CI 同时运行 `go-omni api generate --check` 与 `go test ./...`。
启用映射后,CLI 通过 `go list -deps -export` 加载明确声明的包与依赖,按当前构建环境做类型检查,不执行业务代码、init 或转换函数。采用待生成 DTO 的临时 overlay,避免“新增字段还看旧 DTO”。go.mod/go.sum 的副本及 overlay 都在临时目录,check 不修改项目文件;Go 自己的构建/模块缓存可能更新。使用当前 GOOS/GOARCH/GOFLAGS、`GOWORK=off`;依赖用 go.mod 与 replace 表达,生成超时为 90 秒。
类型包/转换函数包不能依赖输出包 `internal/mapping`;把转换函数放在独立包中,避免导入环。若包本身无法编译,先运行 `go list -deps -export <相关包>` 排查;CLI 不回显可能含私有仓库凭据的 Go 下载输出。纯值字段转换只生成标准 Go 代码,不引入运行时反射搬运、JSON 往返、ORM 或队列依赖。
`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。

## 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()`。

app := omni.New()
measurements := metrics.New()
app.Use(measurements.Middleware())
app.GET("/metrics", measurements.Handler())
// 也可以直接读取 measurements.Snapshot()。
```

# 通用 Go 项目模板
从 v0.28.0-preview 起,`project new/generate/check` 提供不绑定协议与业务的工程骨架。默认只有配置、日志、依赖装配、生命周期和普通 Go 运行入口;不生成 `.api`、HTTP Handler、Swagger、业务任务,也不监听端口、连接数据库或队列。不增加第三方依赖。
## 创建与运行
```sh
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.28.0-preview
go-omni project new demo --module example.com/demo
cd demo
go mod tidy
go run . -check-config
go run . # 默认等待 SIGINT / SIGTERM
go build -o program .
```
目标目录必须为空;未指定 module 时使用目录名。远程安装的 CLI 将自己的固定版本写入 go.mod,无本地替换。当前通用模板要求框架 v0.28.0-preview 或更新版本。源码开发可显式 `--framework-dir /path/to/go-omni`,不会从当前工作目录隐式选择本地框架。`--framework-version` 可指定兼容版本。框架版本、依赖更新由项目修改 go.mod,重新生成不会代为升级依赖。
常驻程序、一次性程序用同一份骨架:项目自己的 `Run` 决定何时完成。完整生成项目见 [examples/program](examples/program/README.md),不需要外部服务。
## 文件职责
| 路径 | 维护方与职责 |
| --- | --- |
| `main.go` | 生成器:信号、启动、运行入口监督、退出状态与日志收尾 |
| `internal/config/loadGen.go` | 生成器:统一配置加载 |
| `internal/svc/runtimeGen.go` | 生成器:依赖初始化及失败收尾 |
| `internal/config/config.go` | 项目:Config、Default、Validate;初始只含 log/lifecycle |
| `internal/config/loader.go` | 项目:按需注册额外文件格式 |
| `etc/config.yaml` | 项目:配置与显式环境引用 |
| `internal/svc/serviceContext.go` | 项目:依赖字段、Init、资源与后台工作登记 |
| `internal/run/run.go` | 项目:Run 的实际实现 |
| `go.mod`、README、.gitignore、其他 Go 文件 | 项目:生成器不覆盖 |
| `.goOmni/projectManifest.json` | 生成器:工程身份、模板版本、生成文件哈希;应提交 Git |
配置遵守 [CONFIG.md](CONFIG.md):默认值 → 文件显式 `${NAME}` / `${NAME:-fallback}` → 类型绑定 → 校验,没有隐式环境覆盖。JSON/YAML/XML 内置;`-config ""` 只用默认值。`-check-config` 不打开日志文件、不初始化依赖、不调用 Run。日志通过独立实例传给 svc,并注入 Context/WorkContext;不替换进程级默认日志实例。
## 运行与退出
```go
func Run(ctx context.Context, deps *svc.ServiceContext) error {
// 一次性程序可完成处理后直接 return nil。
// 常驻程序收到 ctx.Done() 后停止自己的主流程。
<-ctx.Done()
return nil
}
```
`nil` 表示正常完成,返回 error 表示运行失败。后台组件用 `RequestShutdown(err)` 报告致命故障,`RequestShutdown(nil)` 请求正常停止。框架不替项目重试、重新调度或重启任务。
依赖在 `svc.Init` 中装配:创建后立即用 `OnClose` 登记清理,后台组件同时登记同名 `OnStop` 和 `OnDrain`。所有登记应在 Init 返回前完成;Run 不得并发追加生命周期登记。组件何时接收工作由项目决定,停止后不得重新开始领取或启动未登记的工作。
- `Context()` 是提前停止通知,用来停止主流程或接收新工作。
- `WorkContext()` 在正常排空期间仍有效,用于已接受的工作。
- `OnStop` 停止接收新工作,不关闭处理中的工作仍依赖的资源。
- `OnDrain` 返回 nil,必须意味着组件处理、确认和 defer 收尾均已结束。仅返回 `ctx.Err()` 不能证明结束。
- 全部停止钩子先于全部排空钩子;同阶段并行。有先后依赖的组件在一个钩子内显式排序。
- 全部工作确认结束后,资源按 `OnClose` 登记的反序释放,最后关闭入口拥有的日志。
生成入口自动监督 Run 本身,以 `go-omni/project/run` 保留名称登记完成屏障。收到信号、Run 返回或报告故障后开始收尾,同时等待 Run 及其他已登记工作。Run 不应等待资源关闭:资源关闭发生在 Run 完成之后。
初始化失败同样收尾已创建的资源和已启动的工作。Init/Run 内 panic 被转为失败,安全收尾后进程以非零状态退出;任意自建 goroutine 的 panic 仍由项目负责处理。Run 不响应取消或其他工作无法确认结束时,`lifecycle.stopTimeout/drainTimeout/cancelTimeout` 限定等待窗口,返回 `ErrResourcesRetained`,跳过共享资源和日志关闭,以失败状态退出。取消后的工作不能被 Go 强制终止,保留资源不代表工作已经完成。SIGKILL 和进程崩溃不会执行退出钩子。
详见 [生命周期契约](lifecycle/README.md)。现成组件必须按其真实停止/完成语义适配,不能把某个 `Run/Close` 返回直接视为业务结束。
## 生成检查与兼容
```sh
go-omni project generate --dry-run
go-omni project generate
go-omni project check # 等价于 project generate --check
go test ./...
```
生成器不执行项目 Go 代码、不下载依赖。check/预览只读,不创建锁文件;生成时使用独立项目锁、路径和哈希预检。生成文件被手工修改会报冲突,不提供强制覆盖。删除的生成文件可补回;缺失的项目所有文件必须显式恢复,避免把删除的业务文件当成空白骨架重建。
每个文件通过原子替换写入,普通写入失败回滚此前变更;整个目录不具备崩溃事务性。生成期间不要同时手工编辑。发现遗留 project.lock 时,先确认没有生成进程再手工移除。
check 检查模板漂移和必要文件,不检查业务正确性,也不能替代 Go 编译与测试。新的模板版本会重新生成受管文件;不自动合并项目所有文件或更新 go.mod。未知的新清单版本会要求使用兼容 CLI。
原有 `new` / `api new` 及 API 工程行为保留。通用工程使用自己的清单和命令,不能交给 `api generate` 或 `add` 转换;新增业务包直接写普通 Go。现有 `workspace` 命令仍面向 API 契约工程;多个通用工程可分别执行 `project check --dir <目录>`,本版不引入混合工作区配置。

## 通用工程快速开始
```sh
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.28.0-preview
go-omni project new demo --module example.com/demo
cd demo
go mod tidy
go run . -check-config
go run .
# Ctrl+C / SIGTERM 退出;项目自己的 Run 也可以完成后直接返回。
go-omni project check
go test ./...
```
项目只修改配置、svc 依赖初始化和 Run;默认没有 HTTP 端口、数据库、队列或自动重试。`main.go`、加载和装配代码由生成器维护;手改受管文件会报冲突,手写文件保持。完整维护边界、异常退出和超时行为见 [PROGRAM.md](PROGRAM.md)。
## 浏览器跨域 CORS
同源部署保持默认关闭;需要跨域时,在生成项目的配置文件中加入:
```yaml
server:
cors:
enabled: true
allowedOrigins: [https://admin.example.com, https://merchant.example.com]
allowedMethods: [GET, HEAD, POST, PUT, PATCH, DELETE]
allowedHeaders: [Authorization, Content-Type]
exposedHeaders: [Content-Disposition, X-Request-ID]
allowCredentials: false
maxAge: 10m
```
不需要修改 main、Logic 或 `.api`。框架在鉴权前处理合法预检;实际请求仍鉴权,401/404/405/500 保持项目响应格式并附带允许来源的跨域头。没有 Origin 的服务端回调正常处理。配置只决定浏览器读取权限,不替代登录、验签或 CSRF 防护。
手写项目用 `omni.WithCORS(omni.CORSConfig{...})`,独立 HTTP 服务用 `cors.New(...).Wrap(handler)`;代理已经处理 CORS 时保持关闭。完整 [默认值与边界](cors/README.md)、[可运行示例](examples/cors/README.md)。
## 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
业务只维护 Config、Default()、Validate() 和配置文件。生成器维护 Load/main;文件缺失字段保留默认值,显式 0/false/空字符串正常覆盖,固定值不会被同名环境变量再次覆盖。
```go
BatchSize int `json:"batchSize"` // 加入 Config;在 Default() 中设置 BatchSize: 100。
```
```yaml
server:
address: "${HTTP_ADDR:-127.0.0.1:8080}"
batchSize: "${BATCH_SIZE:-100}"
password: "${DB_PASSWORD}"
sessionToken: "${SESSION_TOKEN:-}"
```
`${NAME}` 未设置或为空就报错;`${NAME:-value}` 明确指定备用值。`$$` 转义 `$`;密码中的冒号、换行、引号和 `${...}` 原样插入,不二次解释。JSON/YAML/XML 共用解析后的字段处理和 Go 类型绑定,错误同时定位文件、字段、变量及可用行列,不打印原值。
```sh
go run ./examples/configuration -format xml
DEMO_CLIENT_TIMEOUT=500ms go run ./examples/configuration
# 在生成项目中,仅检查选中的文件,不初始化依赖:
go run . -config etc/config.test.yaml -check-config
```

### 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。
### 减少接入代码:四个常用入口
```yaml
server:
log:
timeZone: Asia/Shanghai
```
时区由 Logger 实例管理,不修改全局 `time.Local`。非法日志级别、数据库端口/连接池等配置会指出 `server.log.level`、`database.port` 等字段和原因,不打印输入值。详见 [配置诊断](CONFIG.md#框架模块的字段诊断)、[日志时区](logx/README.md#实例时区)。
```go
// 本次请求只接受 HTTP 200;默认仍接受所有 2xx。
err := client.JSON(ctx, http.MethodGet, url, nil, &result,
httpc.WithSuccessStatuses(http.StatusOK),
)
// CI/启动时检查类型,无需构造样本;仍使用 Copy 的同一组 Option。
err = copyx.Check[Request, BusinessInput](options...)
```
状态不符合要求返回 `*httpc.StatusError`,不会写入 result,响应体仍由框架关闭。Check 不执行 converter;动态 interface、具体 nil/转换失败和深拷贝引用检查有明确边界,见 [类型预检](COPY.md#类型预检)。完整可运行代码见 [developerTools](examples/developerTools/README.md)。
### 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。

新增通用 Go 工程生成命令 `project new/generate/check`。默认只有配置、日志、svc 依赖装配、生命周期与项目维护的 Run 入口,不生成 API、HTTP Handler、Swagger、业务任务或网络监听,也不自动连接数据库/队列或重试任务。常驻和一次性程序由普通 Go 代码决定。
入口监督 Run 的真实完成并复用现有 Runtime:信号、正常结束、运行错误或初始化失败都会进入收尾;先停止接收工作、等待已登记工作及 Run 结束,再反序释放依赖并关闭日志。Run/Init panic 转为失败;超时仍有工作则传播 ErrResourcesRetained,保留共享资源及日志,以非零状态退出。组件登记在 svc.Init 完成,业务语义和调度方式由项目负责。
配置遵守现有显式文件引用约定;支持 -check-config,在初始化日志和依赖前校验。生成器只管理 main/loadGen/runtimeGen,手写文件保留,生成文件被修改时拒绝覆盖;check/预览只读,独立 manifest/锁和共享文件事务保障生成。新模板要求框架 v0.28.0-preview;已有 new/api/workspace 行为保留,无强制迁移和新增第三方依赖。

新增可独立使用的 i18n 底层模块及可选 HTTP/错误适配。项目维护文案和语言设置,框架提供不可变词典、语言匹配、回退、参数与分支、检查和导出;没有绑定业务身份、页面框架、数据库或响应字段名。
前后端共享版本化消息资源和固定 Unicode CLDR 46.1 基数复数规则。CLI 只读输入,支持源目录提取、缺译/参数/动态引用检查、按命名空间导出语言包和 TypeScript 类型。可选浏览器模块先加载并验证再切换,失败保留当前语言,旧请求不能覆盖新选择。
错误目录新增可选 `translation` 引用。内置响应使用展示译文,原目录文案继续参与契约校验;自定义 Encoder 通过 `PublicMessage()` 显式采用译文。业务码、HTTP 状态、成功/失败语义、cause、直接协议输出和幂等首次快照保持。旧配置与生成项目不启用时无需迁移。
完整 [使用指南](i18n/README.md)、[通用示例](examples/i18n/README.md)、[验收记录](reports/i18nAcceptance.md)。包含 translation 的新契约远程依赖最低版本为 v0.26.0-preview;未使用该元数据的模板最低版本仍为 v0.22。CLI 与框架使用同版。
同时修复 JSON 结束定界符读取失败时丢失原始错误的问题,使请求体超过外层限制时在 Go 1.22 中也保持 HTTP 413;共享目录测试工程使用 Go 1.22。

# v0.25.0-preview
事务失败可以按阶段和已知结果处理,避免把“提交错误”误判为“数据库没有保存”。
- `database.InTx` 签名不变,普通错误返回 `*database.TxError`;Stage 为 begin/work/commit,Outcome 为 notStarted/rolledBack/unknown。成功提交仍返回 nil。
- Commit 报错一律 unknown;回调失败且显式 Rollback 返回 nil 才标记 rolledBack。BeginTx 失败不执行回调。ErrTxDone 不作为回滚成功证据,框架不重试事务。
- `Err` 与 `RollbackErr` 保留两条原因链,可通过 errors.Is/As 识别;APIError、目录参数提示和公开响应继续工作。内部原因不自动进入 HTTP 提示。
- 提供无需外部数据库的 [故障演示](examples/transactions/README.md)。真实 MySQL 与性能结果见 [验收记录](reports/transactionAcceptance.md)。不引入新依赖,不包含文件删除、补偿任务或业务规则。
```sh
go get git.yuntuo.hk/k2safe/go-omni@v0.25.0-preview
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.25.0-preview
go-omni api generate --check
go test ./...
```
**兼容边界:** 既有 errors.Is/As 保持;直接 `err == sentinel`、直接类型断言或字符串匹配需调整。nil context 使用 Background,nil 回调在开启前返回 typed error。panic/Goexit 继续传播并尝试回滚,不转换为 error;标准库自动回滚不公开的原因无法还原,不能推断已回滚。结果仅覆盖按约定使用的当前事务,不覆盖非事务表、隐式提交 SQL、其他连接或外部副作用。GORM 原生 Transaction 没有被替换。
[database 使用规则](database/README.md#事务阶段与结果) 已同步。本轮 runtime 能力需要 v0.25,模板最低版本仍为 v0.22;没有新增必填配置,当前仍为 preview。
49 个测试包全量 race、Go 1.22、vet/build、取消竞争复测通过;成功事务没有新增分配。固定远程版本在空缓存下通过 77 项发布检查和 9 组生成消费者,耗时 71.93 秒。独立 MySQL TLS 容器的 53 条测试记录(含子用例)通过,包含真实提交/回滚后的确认丢失、可选 GORM、生成项目和后台关闭,耗时 28.49 秒。均无本地 replace,标签固定在 `7a177744ab2bb85f23efc0ec267fd905d349bd4b`。见 [远程发布记录](reports/transactionRemote.json)、[远程 MySQL 记录](reports/transactionMySQLRemote.json)。

# v0.24.0-preview(历史版本)
业务项目通过配置开启跨域,不需要手写 OPTIONS Handler 或逐条修改接口。
- 默认关闭,在 `server.cors` 显式配置来源、方法和请求头;统一文件加载、环境引用和字段级诊断自动生效。生成项目无需修改 main、svc 或 `.api`。
- 预检在鉴权前返回 204/403 空响应;实际请求继续鉴权、业务错误编码和路由处理。允许来源可读取 401/403/404/405/500,上传下载和流式能力保留。
- 只支持精确 HTTP(S) 来源,公开无凭据服务可配置单一 `*`;禁止 `*` 与凭据混用。配置初始化快照、请求并发隔离、Vary 缓存分流和有界请求头处理。
- 同一个 App 策略覆盖标准库、native 和 HTTP2;独立服务可使用 `cors.New(...).Wrap(handler)`。没有新增第三方依赖,没有移除现有功能。
```sh
go get git.yuntuo.hk/k2safe/go-omni@v0.24.0-preview
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.24.0-preview
go-omni api generate
go-omni api generate --check
go run . -config etc/config.yaml -check-config
```
现有项目不配置 CORS 时行为不变。代理已处理 CORS 的项目继续关闭;跨域不替代登录、权限或 CSRF 防护。通过 App/Engine/Run 接入,直接对外暴露底层 Router 会绕过应用外层策略。本轮新增 runtime 配置需 v0.24,未使用该配置的模板最低版本仍为 v0.22。
[配置与规则](cors/README.md)、[可运行示例](examples/cors/README.md)、[验收与性能](reports/corsAcceptance.md) 已同步。49 个测试包全量 race、Go 1.22、vet/build、实际生成项目、三种 transport 的 TLS 场景和 20 项真实浏览器检查通过;30 秒 fuzz 约 288 万次。当前仍为 preview。

# v0.23.0-preview(历史版本)
减少业务接入时重复维护的配置校验、HTTP 包装和类型检查。
- 配置诊断定位 database.port、database.pool.maxIdleConns、server.log.level/timeZone 等具体字段,保留文件、环境变量、行列和安全原因;凭据不进入公开提示,原始原因可 errors.Is/As。
- JSON 可传 `httpc.WithSuccessStatuses(200)`,默认仍接受全部 2xx;不匹配时不改目标,继续负责有界读取、关闭和连接回收,不添加新的重试规则。
- `copyx.Check[S,T](options...)` 或已有 Copier.Check 复用同一组 Go 选项,无需样本和映射文件;实际拷贝不再因集合为空而漏过确定的类型不匹配。动态 interface、nil 值、converter 失败及深拷贝共享引用仍有运行时检查。
- `server.log.timeZone: Asia/Shanghai` 配置实例时区;JSON/text/子日志一致,业务 time.Time 属性保持原样。极简镜像可用 `go build -tags timetzdata .` 内置时区数据,库不强制增加体积。
```sh
go get git.yuntuo.hk/k2safe/go-omni@v0.23.0-preview
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.23.0-preview
go-omni api generate
go-omni api generate --check
go run . -config etc/config.yaml -check-config
```
现有调用接口保留;配置错误文本现在更精确,业务应通过类型/字段识别错误。空集合里确定的类型错误会提前暴露,需要显式 converter 或调整实际类型,不应靠空值跳过校验。预检通过不代表 converter 对所有业务值必定成功。当前模板最低版本仍是 v0.22,本轮新增 runtime 能力需使用 v0.23。
[完整示例](examples/developerTools/README.md)、[配置](CONFIG.md)、[JSON 选项](httpc/README.md)、[类型预检](COPY.md#类型预检)、[日志时区](logx/README.md#实例时区)。验收与性能记录见 [本轮验收](reports/developerToolsAcceptance.md)。仍为 preview。

# v0.22.0-preview(历史版本)
配置文件明确决定每个值的来源,项目只维护 Config、Default()、Validate() 和文件。
- `${NAME}` 必填,`${NAME:-fallback}` 在未设置/空字符串时使用备用值,`$$` 转义 `$`。支持字符串组合;环境值不二次展开,凭据空格和特殊字符原样保留。
- 在 JSON/YAML/XML 已解析的字段值上展开,再按目标 Go 类型绑定;缺失字段保留默认值,0/false/空字符串可显式覆盖。字段错误定位文件、环境名和可用行列,不回显值。
- 生成 Load/main 自动接入;新增 `-check-config`,选定一个文件检查,成功退出,不启动日志/依赖/监听。精简生成配置,重新生成保留业务 Config、Default、Validate 和文件。
- **不兼容变更:旧自动环境覆盖、前缀/别名、env/envDefault、database.ConfigFromEnv/ApplyEnv 已移除。** LoadFile/NewReloader 不再接收 prefix,omni.LoadConfig 参数改为文件路径。发现旧标签提示迁移。
- 配置文件中的响应模板用 `$${code}` 等转义;`.api` 中的 `${code}` 不变。日志 file/output/rotation 均由显式文件配置决定,不再隐式清除。
```sh

# v0.21.0-preview(历史版本)
让带认证的 HTTP 调用和内部直连可以直接使用 httpc,减少手写 Transport 与 JSON 响应处理。
- Proxy 支持环境、直连、固定代理;默认保留既有策略。
- 建连、TCP keepalive、TLS 握手、响应头、100-continue、空闲超时和独立空闲连接数量可选配置;不修改全局 Transport,不关闭借用实例。
- JSON 支持 WithHeader / WithHeaders / WithMaxResponseBytes;认证信息逐请求隔离,自动关闭和有界响应处理保留。
- 成功路径减少请求复制和无用退避;output=nil 按限额流式丢弃;小错误体在大小和时间预算内尝试复用连接。
- 不新增依赖、不增加业务规则;Do 保留标准流式扩展。CLI 最新版本与模板最低版本分开,本轮模板兼容门槛仍是 v0.20。
```sh
go get git.yuntuo.hk/k2safe/go-omni@v0.21.0-preview
go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.21.0-preview

**兼容注意**:JSON 旧的直接调用仍有效,自定义 interface/函数值需要同步新增的 variadic 参数。自定义 Transport 与显式连接/代理/阶段参数混用现在报错,避免参数被忽略;迁移时在自己的 Transport 配置,或改用内置字段。没有删除原调用入口。
[参数与使用说明](httpc/README.md)、[可运行示例](examples/httpClient/README.md)、[场景与性能验收](reports/httpcAcceptance.md) 已同步到 README。48 个测试包全量 race、Go 1.22 兼容、vet/build、约 110 万次请求头 fuzz 通过。性能来自本机同条件基准,不能代替项目实际流量验证;仍为 preview。

# v0.20.0-preview(历史版本)
统一配置加载,减少生成项目重复维护的启动代码。
- 生成器维护 `internal/config/loadGen.go`,调用 `config.LoadProject`;项目只扩展 Config/Default/Validate,可选在 loader.go/NewLoader 注册新格式。入口、环境覆盖、日志输出规范化无需业务重复实现。
- JSON/YAML/XML 使用同一个加载与绑定流程;Decoder 通过实例注册,无全局 init 或额外强制依赖。内置格式、字段、文件大小与层数均有明确限制。
- `config.Error` 携带文件、字段、环境变量、可用行列及安全原因;`Invalid` / `AtField` 支持业务验证。保留内部错误链,不自动输出原值;大整数、空集合、null、默认值隔离和自定义反序列化有回归覆盖。
- 配置解析在日志、依赖和监听初始化之前;生成/check/dry-run 使用一致入口和文件所有权规则。
- **迁移要求:旧项目先整理手写 Load,再重新生成。** 不静默覆盖业务文件。低层配置 API 保留;新项目不再复制手写加载流程。固定 Go 数组严格检查长度,YAML alias/merge/custom tag 不再接受,避免模糊覆盖和扩展行为。
```sh

# 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

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。

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。

# go-omni CLI
v0.17 增加公共字段组合、可选结构映射、自动中间件工厂和按需 Repository。配置和迁移见 [生成能力指南](../../GENERATION.md)。
v0.28 新增 `project new/generate/check`:生成无 API、无监听端口和无外部服务依赖的通用 Go 程序,配置/日志/生命周期自动装配,项目维护 svc 与 Run。`project generate --dry-run` 预览,`project check` 只读检查;详见 [通用工程指南](../../PROGRAM.md)。
v0.26 新增 `i18n check|export|types|extract`:检查独立语言资源、提取 Go 静态消息引用或已导出的错误目录,导出指定命名空间的前端包和 TypeScript 类型。输入只读,结果写 stdout;动态引用明确报告。完整命令见 [国际化工具链](../../i18n/README.md#cli-提取检查与导出)。`.api errorCatalog` 可声明 translation 引用,旧 runtime 在生成前拒绝,接入时使用当前同版 CLI 与框架。
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)。

### v0.22 文件显式配置
新生成 `internal/config/loadGen.go` 调用统一加载,纳入生成检查;项目 config.go 只维护字段、默认值和校验,loader.go 用于注册额外格式。JSON/YAML/XML 内置。旧手写 Load 会阻止生成,请先按 [迁移步骤](../../CONFIG.md#v022-迁移旧模式已移除) 整理,不会自动覆盖业务代码。
`go run . -config etc/config.test.yaml -check-config` 只做配置解析和校验,不初始化日志、数据库或监听。文件中的固定值不受环境自动覆盖;`${NAME}` 为必填引用,`${NAME:-fallback}` 提供备用值。

# Go program
This project has no HTTP listener, routes, tasks or external dependencies configured.
```sh
go mod tidy
go run . -check-config
go run .
# SIGINT/SIGTERM stops the program.
go build -o program .
go-omni project generate --dry-run
go-omni project generate
go-omni project check
go test ./...
```
Use the same fixed CLI and framework version. Local --framework-dir is only for
explicit source development; normal creation pins the installed CLI version.
Edit internal/config/config.go (Config/Default/Validate), etc/config.yaml and
internal/config/loader.go for optional decoders. JSON/YAML/XML resolve only
explicit ${NAME} / ${NAME:-fallback}; fixed values are never implicitly overridden.
-check-config validates without opening the logger or dependencies.
Add dependencies in internal/svc/serviceContext.go, registering OnClose immediately.
Register all OnStop/OnDrain hooks in Init, before starting work. Paired hooks use the
same name. OnStop stops acquisition; OnDrain returns nil only after all processing,
acknowledgements and defers finish. Runtime executes stop, then drain, then resource
cleanup in reverse registration order. Callbacks within a phase run concurrently;
combine components with ordering requirements in a single hook. Accepted work uses
WorkContext; Context is the early stop notification. No automatic retry or restart
policy is installed. Adapt external components according to their actual semantics.
Write program behavior in internal/run/run.go. Return nil when a one-shot run finishes;
return an error for fatal failure. The default Run waits for shutdown. Components may
call RequestShutdown(err) to report fatal failure. Signal or Run completion starts
shutdown; the entry waits for Run itself and registered background work. Do not make
Run wait for resource cleanup: cleanup follows Run completion. Do not register hooks
concurrently from Run. The drain name go-omni/project/run is reserved.
Run/Init panics are converted to startup/run failures and registered resources are
cleaned safely. Panics in arbitrary project goroutines must be handled by the project.
Unresponsive work is bounded by lifecycle timeouts: unfinished work causes
ErrResourcesRetained, skips shared resource/logger cleanup and exits unsuccessfully.
Go cannot forcibly stop a goroutine. SIGKILL/process crashes cannot run cleanup.
main.go, internal/config/loadGen.go and internal/svc/runtimeGen.go are generator-owned.
Manual edits cause a conflict. Other starter files are project-owned and preserved;
missing project-owned files require explicit restoration. Check is read-only and
reports missing or stale generated files. It does not compile or execute project code.
Commit .goOmni/projectManifest.json with the project. Generation uses a project lock,
preflight checks and per-file atomic replacement with rollback for ordinary write errors;
it is not crash-atomic across files. Avoid editing files during generation.

go run ./cmd/server
```
运行时配置从 `GO_OMNI_*` 环境变量加载,例如:
配置入口是 `internal/settings.Config`、`Default()`、`Validate()` 和 `etc/config.yaml`。
只有文件里的 `${NAME}` / `${NAME:-fallback}` 会读取环境变量,固定值不受进程环境覆盖。生成的文件已声明地址、网络层,以及所选数据库/存储的必要引用;其他参数直接写进文件。
```sh
GO_OMNI_ENABLE_LOGGER=true GO_OMNI_LOG_LEVEL=debug go run ./cmd/server
```yaml
server:
address: "${GO_OMNI_HTTP_ADDR:-127.0.0.1:8080}"
transport: "${GO_OMNI_TRANSPORT:-nethttp}"
log:
level: debug
shutdownTimeout: 10s
```
`GO_OMNI_HTTP_ADDR` 可以修改监听地址。生成项目默认提供 `/health/live` 和
`/health/ready`,日志、请求 ID 和优雅退出等基础能力由 GoOmni 统一初始化;业务依赖集中放在项目自己的 `internal/servicecontext`。
服务使用 `signal.NotifyContext` 处理 `SIGINT` / `SIGTERM`。部署时构建并运行服务二进制,
使信号直接到达服务进程:
用 `-config` 选择一个 YAML/JSON/XML 文件;`-config ''` 只使用 Default();`-check-config` 仅加载和校验,不创建依赖或监听:
```sh
go run ./cmd/server -config etc/config.yaml -check-config
go build -o server ./cmd/server
./server
./server -config etc/config.yaml
```
`GO_OMNI_SHUTDOWN_TIMEOUT` 控制等待请求完成的时间,默认 `10s`。
服务通过 `signal.NotifyContext` 处理 `SIGINT` / `SIGTERM`,先排空 HTTP 请求,再关闭依赖和日志。生成项目默认提供 `/health/live` 和 `/health/ready`,业务依赖集中在 `internal/servicecontext`。
使用支持统一网络配置的框架版本时,设置 `GO_OMNI_TRANSPORT=native` 即可切换为自研 HTTP/1.1;
默认 `nethttp`。`GO_OMNI_TLS_CERT_FILE` 和 `GO_OMNI_TLS_KEY_FILE` 配对启用 HTTPS。
实验版 HTTP/2 使用 `GO_OMNI_TRANSPORT=http2`,必须同时配置 TLS 证书和私钥。
业务 Handler / Service / Repository 不需要修改;三种适配器共用上述退出等待时间。
通过文件中的引用设置 `GO_OMNI_TRANSPORT=native` 可切换自研 HTTP/1.1,默认 nethttp。HTTPS 在文件的 `server.tls.certFile` / `server.tls.keyFile` 成对配置;实验 HTTP/2 选择 `http2` 且必须配置 TLS。不会自动读取未在文件声明的 TLS 环境变量。
{{if eq .Database "mysql"}}
`/health/ready` 已注册数据库探针:连接失败返回 `503`,数据库恢复后重新返回 `200`。
`/health/live` 始终只检查服务存活。`GO_OMNI_DB_PING_TIMEOUT` 限制初始化检查和数据库探针的等待时间。
退出时先排空 HTTP 请求,再关闭数据库连接池,最后关闭日志。
`/health/ready` 已注册数据库探针,连接失败返回 503,恢复后返回 200;`/health/live` 只检查进程存活。连接池参数直接写入 `database`,缺失字段保留 Default():
数据库连接池参数:
```text
GO_OMNI_DB_MAX_OPEN_CONNS=10
GO_OMNI_DB_MAX_IDLE_CONNS=5
GO_OMNI_DB_CONN_MAX_LIFETIME=30m
GO_OMNI_DB_CONN_MAX_IDLE_TIME=5m
GO_OMNI_DB_PING_TIMEOUT=5s
```yaml
database:
driver: mysql
dsn: "${GO_OMNI_DB_DSN}"
maxOpenConns: 10
maxIdleConns: 5
connMaxLifetime: 30m
connMaxIdleTime: 5m
pingTimeout: 5s
```
`MAX_IDLE_CONNS=0` 禁用空闲连接,`MAX_OPEN_CONNS=0` 表示不限制连接数。
项目会启用 MySQL `parseTime` 并按 UTC 读取 DATETIME 字段,JSON 字段保持 lowerCamelCase。
`maxIdleConns: 0` 禁用空闲连接;此项目要求 maxOpenConns 为正数。项目启用 MySQL parseTime,并按 UTC 读取 DATETIME;JSON 字段保持 lowerCamelCase。
