Response to: Automatic Swap of Target Class

Hi Russ
I am attempting to replace ClassA target to ClassB. So the pattern that I am trying to use is (if the package is com.xx), pointcut on com.xx.Class*, anything with Class on their name within the package will be replaced with ClassB. And ClassA is not an interface.


I have used advises via methods,also using interfaces in spring, but for class, I only have seen it in AspectJ.


It seems like jointpoints in spring framework is just limited to methods, and not classes yet. Here is the excerpt from the spring :
"Joinpoint: Point during the execution of a program, such as a method invocation or a particular exception being thrown. In Spring AOP, a joinpoint is always method invocation. Spring does not use the term joinpoint prominently; joinpoint information is accessible through methods on the MethodInvocation argument passed to interceptors, and is evaluated by implementations of the org.springframework.aop.Pointcut interface."


At the moment, I am still looking at the AspectJ document, coz I might just overlooked this.


Thanks for the reply
