Joinpoint

A joinpoint is a well-defined point during the execution of your application. Typical examples of joinpoints include a method call, method execution, class initialization, and object instantiation. Joinpoints are a core concept of AOP and define the points in your application at which you can insert additional logic using AOP.

Spring AOP only supports one joinpoint type—method invocation. This makes Spring more accessible. But if we need to advise some code at a joinpoint other than a method invocation, we can always use Spring and AspectJ together.
