I used Dagger to inject dependencies on a Java Lambda:

我使用Dagger在Java Lambda上注入依赖项：


public class LambdaEntryPointHandler implements RequestHandler<SQSEvent, SQSBatchResponse> {
    private final Handler handler;

    public LambdaEntryPointHandler() {
        ServiceComponent component =  DaggerServiceComponent.create();
        handler = component.getRequestHandler();
    }

    @Override
    public SQSBatchResponse handleRequest(final SQSEvent sqsEvent, final Context context) {
        return handler.handleRequest(sqsEvent, context);
    }
}

I need to access the awsRequestId of the context in a call far down the chain of calls, it's really tedious to pass the context object as a parameter to all the caller functions. I was wondering if using Dagger I could inject the context as a dependency to that class that uses it, instead of passing the parameter.

我需要在调用链下游的调用中访问上下文的awsRequestID，将上下文对象作为参数传递给所有调用者函数真的很繁琐。我想知道是否可以使用Dagger将上下文作为依赖项注入使用它的类，而不是传递参数。


I'm open to other suggestions, is there a global store available in this case? (Something like redux in react, to avoid passing props down the component tree)

我对其他建议持开放态度，这种情况下有没有全球商店？(类似Reaction中的redux，以避免在组件树中传递道具)


I saw this answer, but I don't use Spring.

我看到了这个答案，但我没有使用Spring。
