spring mvc4 动态切换语言不起作用5

我利用 SPRING4 MVC配置了动态切换语言，全是不起作用。请高手看看：

spring-servlet.xml

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">   <mvc:annotation-driven/>  <context:component-scan base-package="com.efs.business"/>  <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp"/> <property name="suffix" value=".jsp"/> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> </bean>  <mvc:interceptors>  <mvc:interceptor> <mvc:mapping path="/*"/> <ref bean="localeChangeInterceptor"/> </mvc:interceptor> </mvc:interceptors>  <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource"> <property name="basename" value="com.efs.resource.Message"/> </bean> <bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver"> </bean> <bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor"> <property name="paramName" value="locale"/> </bean>  </beans>

切换语言的Controller

package com.efs.business.locale;

import java.util.Locale;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.LocaleResolver;

@Controller
@RequestMapping("/locale")
public class SysLocaleController
{
	@Autowired
	private LocaleResolver localeResolver;
	
	@RequestMapping("/changeLocale")
	public String changeLocale(String locale,HttpServletRequest request,HttpServletResponse response)
	{
		Locale l = new Locale(locale);
		localeResolver.setLocale(request, response, l);
		return "redirect:/demo/index.do";
	}
}

页面JSP页面：
<a href="<%=basePath%>/locale/changeLocale.do?locale=zh_CN">中文</a> |
<a href="<%=basePath%>/locale/changeLocale.do?locale=en_US">English</a>
