Long: `扫描源码中带有 @provider 注释的结构体，生成 provider.gen.go 实现依赖注入与分组注册。
|
||
|
||
注释语法：
|
||
@provider(<mode>):[except|only] [returnType] [group]
|
||
- mode：grpc|event|job|cronjob|model（可为空）
|
||
- :only：仅注入字段 tag 为 inject:"true" 的依赖
|
||
- :except：注入除标注 inject:"false" 之外的非标量依赖
|
||
- returnType：Provide 返回类型（如 contracts.Initial）
|
||
- group：分组（如 atom.GroupInitial）
|
||
|
||
模式特性：
|
||
- grpc：注入 providers/grpc.Grpc，设置 GrpcRegisterFunc
|
||
- event：注入 providers/event.PubSub
|
||
- job|cronjob：注入 providers/job.Job，并引入 github.com/riverqueue/river
|
||
- model：需要 Prepare 钩子
|
||
|
||
行为说明：
|
||
- 忽略标量类型字段，自动补全 imports
|
||
- 以包为单位生成 provider.gen.go
|
||
- 可与 gen route 联动（其 PostRun 会触发本命令）`,
