Re: [aspectj-users] How to access annotation values

[Eduardo Rocha <eduardorochabr@xxxxxxxxx>]

Hi Andreas,

You should write something like this:

void around(): execution(@NeedPermissionGroup * hello.World.*())  {
    MethodSignature signature = (MethodSignature) thisJoinPoint.getSignature();
    NeedPermissionGroup ann =
signature.getMethod().getAnnotation(NeedPermissionGroup.class);

    System.out.println(ann.id());

    proceed();
}
