Needs help for AoP implementation with Spring

[Yao Mingming]

This is my very first time to use Spring. I'm having trouble in my AoP implementation. What I�m doing is simple: one interface called Knight with one method getMyFavouratePizza(), the implementation of this interface is KnightImpletation. To feel Spring's AoP, I am going to add a simple logging feature to the getMyFavouratePizza() method by AoP, therefore, I use MethodBeforeAdvice interface here. But the result is frustrating. It seems that the AoP has never been invoked by Spring. The following is my xml configuration file: (note: I'm using NameMatchMethodPointcut for the PointCut, but when I change to RegexpMethodPointcutAdvisor, it's the same. Nothing happens.)

Just wondering if miss anything here. Or could anyone help me out?
