A join point in the context of Spring AOP (Aspect-Oriented Programming) represents a specific point during the execution of a program where an aspect can be applied. This could be a method execution, exception handling, or even a change in the object variable's value. In Spring AOP, join points are primarily method executions, which means that the framework allows you to define at which point in the execution of a method an advice should be applied[1][2][3][4][5][6].
For example, an advice can be configured to execute before a method is invoked (Before advice), after it completes successfully (AfterReturning advice), if it throws an exception (AfterThrowing advice), or both before and after the method execution (Around advice)[1][3][4].
