使用Spring 3.1.2实现@AspectJ时面临的问题

Question

我试图在Spring3.1.5上用AOP实现日志记录。但在运行时,我会得到以下异常

Caused by: org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.context.support.ClassPathXmlApplicationContext]: Constructor threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.manh.fm.bid.ejb.BidMgr' defined in class path resource [appCtx-fm.xml]: Initialization of bean failed; nested exception is org.springframework.aop.framework.adapter.UnknownAdviceTypeException: Advice object [null] is neither a supported subinterface of [org.aopalliance.aop.Advice] nor an [org.springframework.aop.Advisor]

下面是我的aspect类的详细信息：

@Aspect
public class LoggingAspect {


    @Before("allGetters()")
    public void LoggingAdvice(){

        System.out.println("AspectJ Logging");
    }
    @Pointcut("execution(* com.manh.fm.kjb.MgrBean.processMyAction(..))")
    public void allGetters(){}

}

    </bean>
<bean id="loggingAspect"

</beans>

伙计们，我真的被这个困住了，我也是Aop的新手，请帮我解决这个问题！！！

尝试实现“org.aopalliance.intercept.MethodInterceptor”，它是“org.aopalliance.aop.advice”的“子接口”，正如错误所暗示的那样。
