The State of AOP
A lot is happening in the field of Aspect-oriented programming (AOP). AspectJ and AspectWerkz, the two leading AOP implementations, have merged, bringing in their respective strengths. The merged version, AspectJ 5, adds many new features aimed at simplifying writing and deploying aspects. The new features include an annotation-based and XML-based syntax to define aspects, support for new Java 5 concepts, and load-time weaving. The tools support for AOP continues to improve, as well. Further, the most popular IOC framework, Spring, enables integrating aspects written in AspectJ. There is also serious discussion and preliminary work going on to support AOP right into the VM itself. All in all, there is a lot to learn about the changes in the exciting field of AOP. This session is designed to help you get up to date with all these changes.
This session provides a guided tour of the new things in the AOP world. It explains new features in AspectJ along with the practical considerations in utilizing each of them. The presentation explores the fundamental synergy between AOP and metadata to understand right (and wrong) utilization of metadata-based crosscutting. Load-time weaving (LTW) enables adding aspects to your existing applications deployed in any application server with a minimal effort. The presentation shows how to utilize LTW to improve your productivity considerably, even if you don't yet subscribe to the AOP philosophy and don't want to use AOP in production. The presentation also demos the latest AspectJ Development Tool (AJDT) in Eclipse (that has improved a lot) to make Java developers feel home when developing with aspects. The presentation includes many demos to reinforce the concepts learned, as well as give a feel for what it would be like to apply aspects written using new features.
This session is particularly targeted at developers with good familiarity with AOP concepts and the AspectJ language. It is recommended to attend the “Introduction to Aspect-oriented programming with AspectJ” session or read articles and/or books that introduce AOP and AspectJ to obtain the prerequisite.
