Dependency Injection with AspectJ and Spring

An anonymous reader writes "IBM DeveloperWorks has an interesting article about the complementary aspects of dependency injection and aspect-oriented programming. Adrian Colyer, Chief scientist of Interface21, examines how to combine these two techniques to 'facilitate advanced dependency injection scenarios.' From the article: 'Dependency injection and aspect-oriented programming (AOP) are two key technologies that help to simplify and purify domain models and application layers in enterprise applications. Dependency injection encapsulates the details of resource and collaborator discovery, and aspects can (among other things) encapsulate the details of middleware service invocations'"

Spring

If you think you even might be involved in a new j2ee proj., a good book that explains much of this complexity (or maybe buzz) is Rod Johnson's (of Spring notoriety) J2EE without EJB. I think their movement suffers to some degree from over abstraction, but it does beat EJB and is my choice for j2ee development.

I'd rather use RoR or any other dynamic language for web dev in general. However, there are still many business requirements that can come up (OLAP for one - Mondrian) that keep me coming back to j2ee for now.

The Spring framework reduces IoC and AOP to configuration details (XML - blech) so you don't have to worry to much about the implementation. Very powerful I'm sure in the hands of a seasoned Spring user.

one good project from this?

Aside from more jargonism, can anyone cite one major application, one major project for which this was used?

I'm signing up for my 10-year training plan to learn the terminology, jargon, etc.

Then I'll consider if I even want to learn to apply it. Sheesh, this is embarrassing
