Article on Spring and AOP

An excellent article on Spring, AOP, EJBs and testing has been published on from Eugene Kuleshov. It’s intended for Spring newcomers and intermediate users. I have just read it and highly recommand it.

It deals with:

  • Simplifying usage of EJB (SSB here) by delegating to Spring beans and how to inject Spring beans in EJBs
  • Weaving application logic in Spring beans without modifying them using AOP
  • Testing techniques by mocking beans which rely on infrastructure components with Junit and JMock

I wasn’t aware of using Spring’s BeanPostProcessor to switch beans at runtime which prevents from writing another applicationContext.xml file for testing.
