Re: [aspectj-users] Pointcut definition with annotations

[Adrian Colyer <adrian.colyer@xxxxxxxxx>]

The *target* of the call is the target object, and @target will match
any call where the runtime type of the target of a call has the given
annotation. It would match in your case if Foo had the
@ManagedResourceAnnotation. However, you are trying to match
annotations not on the target, but on the method that gets invoked.
For this you need to use @annotation.

So you should write:

pointcut  annotatedResourceInvocation() : call(* *(..)) &&  
                                                           
@annotation(ManagedResourceAnnotation);
