Spring AOP After and Around Advice Type

Advice: Action taken by an aspect at a particular join point. Different types of advice include "around," "before" and "after" advice. Advice types are discussed below. Many AOP frameworks, including Spring, model an advice as an interceptor, maintaining a chain of interceptors "around" the join point.

We'll learn about the After Advice types: After (finally), AfterReturning and AfterThrowing.
