Class MethodInvocationProceedingJoinPoint

java.lang.Object
  org.springframework.aop.aspectj.MethodInvocationProceedingJoinPoint

All Implemented Interfaces:

org.aspectj.lang.JoinPoint, org.aspectj.lang.JoinPoint.StaticPart, org.aspectj.lang.ProceedingJoinPoint

public class MethodInvocationProceedingJoinPoint
extends java.lang.Object
implements org.aspectj.lang.ProceedingJoinPoint, org.aspectj.lang.JoinPoint.StaticPart

Implementation of AspectJ ProceedingJoinPoint interface wrapping an AOP Alliance MethodInvocation.

Note: the getThis() method returns the current Spring AOP proxy. The getTarget() method returns the current Spring AOP target (which may be null if there is no target), and is a plain POJO without any advice. If you want to call the object and have the advice take effect, use getThis(). A common example is casting the object to an introduced interface in the implementation of an introduction.

Of course there is no such distinction between target and proxy in AspectJ.

Since:

2.0
