Suppose there are 10 methods in a class as given below: There are 5 methods that starts from m, 2 methods that starts from n and 3 methods that starts from p. Understanding Scenario I have to maintain log and send notification after calling methods that starts from m. Problem without AOP We can call methods (that maintains log and sends notification) from the methods starting with m. In such scenario, we need to write the code in all the 5 methods. The AspectJ around advice is applied before and after calling the actual business logic methods.
