What is Joint point and Point cut? - Sudipta13samanta/Spring GitHub Wiki

Join 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 join point always represents a method execution. For example, all the methods defined inside your EmployeeManager interface cab be considered joint points if you apply any cross-cutting concern of them.

Pointcut is a predicate or expression that matches join points. Advice is associated with a pointcut expression and runs at any join point matched by the pointcut (for example, expression “execution(* EmployeeManager.getEmployeeById(..))” to match getEmployeeById() the method in EmployeeManager interface). The concept of join points as matched by pointcut expressions is central to AOP, and Spring uses the AspectJ pointcut expression language by default.
