1、配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
  <display-name>springmvc_fileupload</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
  
<!--   <listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener> -->

  <filter>
    <filter-name>encodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>encodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
  
  
  <servlet>
    <servlet-name>springmvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springmvc-servlet.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>*.action</url-pattern>
  </servlet-mapping>
  
  
</web-app>

2、配置springmvc-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:mvc="http://www.springframework.org/schema/mvc"
	xmlns:aop="http://www.springframework.org/schema/aop" 
	xmlns:tx="http://www.springframework.org/schema/tx" 
	xmlns:context="http://www.springframework.org/schema/context" 
	xmlns:c="http://www.springframework.org/schema/c"
	xmlns:cache="http://www.springframework.org/schema/cache"
	xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
		http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-4.0.xsd
		http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
		http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
		http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">
	
	<context:component-scan base-package="com.wh.handler"></context:component-scan>
	
	<context:annotation-config />  <!--激活Bean中定义的注解 -->
    <mvc:annotation-driven />
    
	<!-- 配置国际化文件 -->
	<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
    <!-- 国际化信息所在的文件名 -->                     
    <property name="basename" value="http://www.mamicode.com/messages" />   
    <!-- 如果在国际化资源文件中找不到对应代码的信息，就用这个代码作为名称  -->
    <property name="useCodeAsDefaultMessage" value="http://www.mamicode.com/true" />
	</bean>

</beans>

3、编写index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="http://www.mamicode.com/">
    
    <title>My JSP ‘index.jsp‘ starting page</title>
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">    
	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
	<meta http-equiv="description" content="This is my page">
  </head>
  <body>
  
    <!-- ${pageContext.request.contextPath} 这个是比较重要的，否则路径老是不对  -->
    <form action="${pageContext.request.contextPath}/intern.action" method="get">
    	<input type="text" name="un" value="http://www.mamicode.com/xxx"/> <br/>
    	<input type="submit" value="http://www.mamicode.com/提交"/>   <br/>
    </form>
    
  </body>
</html>

4、编写handler.java

package com.wh.handler;

import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.support.RequestContext;

@Controller
public class InternationHandler {

	@RequestMapping("intern.action")
	public String demo(HttpServletRequest request){ 
		System.out.print("后台国际化:");
		//后台代码中通过RequestContext对象的getMessage方法获取国际化信息
		RequestContext requestContext = new RequestContext(request);
        String msg = requestContext.getMessage("uname");
        System.out.println("msg:"+msg);
		return "hello.jsp"; 
	}
}

5、编写hello.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <title>My JSP ‘index.jsp‘ starting page</title>
  </head>
  <body>
  		<!-- 浏览器问题，有的浏览器不支持国际化，比如360浏览器 -->
	          前端国际化 <br>
	    <spring:message code="uname"></spring:message>
  </body>
</html>

注意：要先从index页面，经过后台处理，再到前台hello页面才行，同时，要注意浏览器问题，一个浏览器不支持国际化，试试其他浏览器。
