你好，請教有關spring aop方面的問題。
我查詢到這個資料，http://opensource2.atlassian.com/confluence/spring/display/DISC/Caching+the+result+of+methods+using+Spring+and+EHCache
可是在運行的時候，卻碰到這樣奇怪的錯誤
說Failed to convert property value of type [com.sscm.core.service.MethodCacheInterceptor] to required type [org.aopalliance.aop.Advice] for property 'advice'
public class MethodCacheInterceptor implements MethodInterceptor, InitializingBean
為什么會這樣呢？
MethodInterceptor是Advice的子接口阿
Advice->Interceptor->MethodInterceptor
MethodCacheInterceptor實現的MethodInterceptor
按理說不應該這樣啊。請問這是為什么?
