Question

How to make an aspect that targets all public methods that belong to a class that is marked with specific annotation? In following method1() and method2() should be processed by the aspect and method3() should not be processed by the aspect.

@SomeAnnotation(SomeParam.class)
public class FooServiceImpl extends FooService {
    public void method1() { ... }
    public void method2() { ... }
}

public class BarServiceImpl extends BarService {
    public void method3() { ... }
}

If I put annotations on method level, this aspect will work and match the method calls.

@Around("@annotation(someAnnotation)")
public Object invokeService(ProceedingJoinPoint pjp, SomeAnnotation someAnnotation) 
 throws Throwable { 
   // need to have access to someAnnotation's parameters.
   someAnnotation.value(); 

}

I am using Spring and proxy based aspects.

The following should work

@Pointcut("@target(someAnnotation)")
public void targetsSomeAnnotation(@SuppressWarnings("unused") SomeAnnotation someAnnotation) {/**/}

@Around("targetsSomeAnnotation(someAnnotation) && execution(* *(..))")
public Object aroundSomeAnnotationMethods(ProceedingJoinPoint joinPoint, SomeAnnotation someAnnotation) throws Throwable {
    ... your implementation..
}
