使用特定注释对所有方法调用带注释的方面

Question

I have an application based on MVC and I want to log inputs/outputs from all my controllers.
Also, each of my controller methods is annotated with some specific annotation (eg: @MyControllerMethod ).
I wrote an Annotated Aspect which works fine when I use the annotation (eg: LogRequestReply ) from the aspect on my controller methods.

@Around("@annotation(com.xyz.LogRequestReply)")
public Object logRequestResponse(ProceedingJoinPoint pjp) throws Throwable {

@MyControllerMethod
@LogRequestReply /* It invokes my logRequestResponse method */
public ResponseEntity controllerMethodA(...) {}

However, I have a lot of controller methods and each with annotation MyControllerMethod .
Is there a way I can make my aspect annotation make work on all controller methods by default, such that each of the methods automatically calls my aspect logger and I can log the inputs/outputs?

Note: I also looked into writing an interceptor extending from HandlerInterceptorAdapter . But it has its own complexity of being able to log request/response where the stream can only be read once.

Please suggest.

One option is to let the @Around definition less restrictive, add a restriction by package or something like that. Internally you can check if this is a Controller by this check bellow and then print the request/response:

@Pointcut("within(com.mypackage.controller..*)")
private void inControllerPackage() {
}

@Around("inControllerPackage()")
public Object logRequestResponse(ProceedingJoinPoint pjp) throws Throwable {
    if (pjp.getSignature().getDeclaringType().isAnnotationPresent(RestController.class)) {
       ...
    }
