Annotate Java method for logging its result and exceptions

Is it possible to log result,that method returned with annotation?

or specific Exceptions,that was thrown by method?

Can't find return value for method m or something like that ,using this call:

for (Method m : Class.forName("AnnotatedBe开发者_JS百科an").getMethods()) {
  ...
}

AnnotatedBean is class,which methods annotated by custom annotation.

This seems textbook example of separation of concerns. Take a look at AspectJ; production aspects can work very well in this situation.

Now I am confused. How can return value "not be found"?

You need to invoke the method to get a return value back.

for (Method m : Class.forName("AnnotatedBean").getMethods()) {
    Object returnValue = m.invoke(instance, args);
}
