I'm using guice for dependency injection with aop from aopalliance. I can't quite figure out what's aopalliance all about and who implemented the version (dated from 2004) that's on their sourceforge page. Why is guice using this version instead of a more known package such as AspectJ?
Also, do you know of any tutorials on the aopalliance version?
AOP Alliance is a set of interfaces that multiple frameworks implement (see AOP Alliance Motivations), including both Guice and Spring.
AOP Alliance was chosen for Guice because it has a high capability and a simple API.
The Guice wiki has an AOP guide.
