We use aspectj for defining and using an aspect that serve an automatic objects caching service. It's not so hard, you can see our notes here: http://www.simexplorer.org/wiki/DevDoc/AspectJ

AspectJ supports annotations pretty well plus you still have all the old methods of defining a pointcut (or combination) if you need to really specific.

e.g.

@Around("@annotation(com.mycompany.BoundProp)")

would match all methods annotated with @com.mycompany.BoundProp

and you could still say only setters with 1 argument should be bound (since it might make sense to do that)

@Around("@annotation(com.mycompany.BoundProp) && execution(public * *..*.set*(*))")

Thanks for your comment btilford. I did not know this. Still, this is slightly opposite approach. The end user still needs to deal with aspect and with meaning of @Around and pointcut public * *..*.set*(*)) and setup the AspectJ compiler. I'm seeking for the possite: The user downloads library with com.mycompany.BoundProp annotations, applies the annotation to one of its classes and as a result all the setters in the class will become bounded. This is not big shift technologically, I guess, but huge improvement in ease of use. Not talking about the fact that it opens the door to create a market of reusable aspects.
