spring拦截器为什么不起作用了？

spring.xml里的一段代码：
<bean id="menu_log"
class="com.dne.kiss.admin.menu_log.Menu_Log_Interceptor">
<property name="menuService" ref="menuService"></property>
</bean>
<bean id="menu_log_proxy"
class="org.springframework.aop.framework.ProxyFactoryBean">
<property name="proxyTargetClass">
<value>true</value>
</property>
<property name="interceptorNames">
<list>
<value>menu_log</value>
</list>
</property>
<property name="target">
<ref bean="/login" />
</property>
</bean>

拦截器类：
package com.dne.kiss.admin.menu_log;

import java.lang.reflect.Method;

import org.springframework.aop.MethodBeforeAdvice;

import com.dne.kiss.admin.service.IMenuService;

public class Menu_Log_Interceptor implements MethodBeforeAdvice {
private IMenuService menuService;

public IMenuService getMenuService() {
return menuService;
}

public void setMenuService(IMenuService menuService) {
this.menuService = menuService;
}

public void before(Method arg0, Object[] arg1, Object arg2)
throws Throwable {
// TODO Auto-generated method stub
System.out.println("---------------------------------haha,你被我拦截了");
}

}

我的意图是拦截所有的action,也就是spring.xml中所有以'/'开头的bean.现在我配的只拦截/login.但是这段代码根本不起作用，请问高手这是这么回事？能指点下么？
