在线等：Spring MVC 拦截器拦截失败

项目架构用的是springMVC，版本是spring2.X。
我的配置文件如下：

<bean id="loginInterceptor" class="com.company.program.interceptor.LoginInterceptor" />

	

	<!-- 判断用户会话是否失效 -->

	<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" >

	    <property name="interceptors">

	       <list>

	          <ref bean="loginInterceptor"/>

	       </list>

	    </property>

	</bean>

java类如下：

package com.company.program.interceptor;



import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;



import org.springframework.web.servlet.ModelAndView;

import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;



import com.company.program.bean.UserInfo;

/**

 * 用户登录会话校验

 *

 */

public class LoginInterceptor extends HandlerInterceptorAdapter  {

	private String mappingURL;

	public void setMappingURL(String mappingURL) {

		this.mappingURL = mappingURL;

	}

	

	

    /**

     * 在DispatcherServlet完全处理完请求后被调用

     */

	@Override

	public void afterCompletion(HttpServletRequest arg0,

			HttpServletResponse arg1, Object arg2, Exception arg3)

			throws Exception {

		System.out.println("--sdfsd");

		// TODO Auto-generated method stub

		

	}

	

	

    /**

     * 在业务处理器处理请求执行完成后,生成视图之前执行的动作

     */

	@Override

	public void postHandle(HttpServletRequest arg0, HttpServletResponse arg1,

			Object arg2, ModelAndView arg3) throws Exception {

		System.out.println("--sdfsd");

		// TODO Auto-generated method stub

		

	}

	

	

    /**

     * 在业务处理之前调用

     */

	@Override

	public boolean preHandle(HttpServletRequest request, HttpServletResponse response,

			Object arg2) throws Exception {

		System.out.println("--sdfsd");

		String url=request.getRequestURL().toString();   

		UserInfo userInfo = (UserInfo) request.getSession().getAttribute(

				"userInfo");

		if (mappingURL == null || url.matches(mappingURL)) {

			if (userInfo == null)

				response.sendRedirect("/login.htm");

			return false;

		}     

        return true; 

	}



}

但实际运行过程中任何请求都没有进入我设好的拦截器，不知道哪配置有问题，各位大虾帮忙看看哪出的问题！
