Add a scheduled task server, dependency injection error

[tutengdihuang]

我想在newApp添加一个我自己写的cron server： cs *server.CronServer
func newApp(logger log.Logger, gs *grpc.Server, hs *http.Server, cs *server.CronServer) *kratos.App {
return kratos.New(
kratos.ID(id),
kratos.Name(Name),
kratos.Version(Version),
kratos.Metadata(map[string]string{}),
kratos.Logger(logger),
kratos.Server(
gs,
hs,
cs,
),
)
}

执行依赖注入报错inject wireApp: no provider found for *invalid type
provider已经写入： 在server 包中
var ProviderSet = wire.NewSet(
NewGRPCServer,
NewHTTPServer,
NewCronWorker,
)
请帮忙解决一下或者给一个例子

根据我在Kratos仓库中找到的类似问题，你可能需要将你的wokerStartup函数改为依赖于特定的Job实例：

func wokerStartup(job1 worker.JobA, job2 worker.Job2) {
    jobs := []worker.Job{job1, job2}
    for i := 0; i < len(jobs); i++ {
        jobs[i].Handle()
    }
}

如果wokerStartup函数比较复杂并且需要被重用，你可以使用Option模式：

首先，创建一个新的WorkerOption：

type WorkerOption struct{
    Jobs []worker.Job
}

然后让wokerStartup依赖于这个WorkerOption。NewWorkerOption应该依赖于特定的Job实例。

这个解决方案来自于Kratos仓库的这个问题。

如果你在实施这个解决方案时遇到任何问题，或者这个解决方案不能解决你的问题，请提供更多的信息，我会尽我所能帮助你。

Is the injected type the same as the dependent type

Is the injected type the same as the dependent type

Thanks for your replay, and I have fixed the issue, because of the type problme. And thanks again!
