Spring AOP - Join Point

In Spring AOP, while we create business logic of the method we usually need to inject the services at different places or points. So we call these places or points as JoinPoint.

At a join point place services will be injected at run time. And while executing business logic of method, the services can be injected in following 3 join points.

  • Before business logic of method starts
  • After business logic of method complete
  • If business logic of method throws exception at run time.

In a join point, many Aspects(just name, not implementation) can be injected. Actually the Advice(the implementation of Aspect) is injected.
