AOP Concepts and Terminology

An important term in AOP is advice. It is the action taken by an aspect at a particular join-point. (Code which need to be executed before / after / around i.e. Entry point code).

Joint point is a point of execution of the program, such as the execution of a method or the handling of an exception. In Spring AOP, a joint point always represents a method execution.

(Method for which we are doing this in our case it is returnCash () and receivePayment () method)

Pointcut is a predicate or expression that matches join points.

(In our case it is a condition when to call like before or after)

Aspect is associated with a pointcut expression and runs at any join point matched by the pointcut. Spring uses the AspectJ pointcut expression language by default.
