springmvc国际化 基于请求的国际化配置

基于请求的国际化配置是指，在当前请求内，国际化配置生效，否则自动以浏览器为主。

项目结构图:

说明:properties文件中为国际化资源文件.格式相关见文章: http://www.cnblogs.com/dennisit/p/3359008.html

这里不同点是,在国际化资源文件中增加参数位.例如:messages_ja.properties如下

main.target=愛してる
main.title=こんにちは {0},{1}

 

web.xml文件中声明spring监听与上下文资源、spring-mvc应用文件.

    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

spring-context.xml文件中声明国家化

 

<?xml version="1.0" encoding="UTF-8"?>

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

   <!-- 定义国际化消息

    -->   
   <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">   
     
     <!-- 其中basename用来指定properties文件的通用名
              如实例中的messages_en.properties,messages_ja.properties通用名都是messages
      -->
     <property name="basename" value="messages" />
     <property name="defaultEncoding" value="UTF-8"/>
     <property name="useCodeAsDefaultMessage" value="true" />
     
   </bean>   
   
</beans>

 

servlet-context.xml文件中声明springmv相关,并定义国际化请求处理拦截器,处理用户请求式国际化

 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure -->

    <mvc:annotation-driven />

    <context:component-scan base-package="com.pudp" />
    
    
    <!-- 配置基于Session的处理,将提交上来的locale参数进行处理 -->  
    <bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver">
        <!-- 该属性可以不用配置 -->
        <property name="defaultLocale" value="ja"></property>
    </bean>  
    
    <!-- 国际化请求拦截器处理 -->
    <mvc:interceptors>  
        <bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor" />  
    </mvc:interceptors>  
    
    <!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/" />
        <property name="suffix" value=".jsp" />
    </bean>
    
    
</beans>

 

视图层实现国际化请求处理

 

<%@ 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">

      <!-- 使用message 标签配置需要显示的国际化文本, 
           code对应国际化文件中对应的键的名称,arguments 对应国际化属性文件中的参数。 -->
    <p>
           <spring:message code="main.title" arguments="苏若年,林允熙"/> ,
           <spring:message code="main.target"/>
    </p>
  </body>
</html>

 

springmvc控制器类实现

 

package com.pudp.controller;

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

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

/**
 * description:
 *
 * @author <a href='mailto:dennisit@163.com'> Cn.苏若年 (En.dennisit)</a> Copy Right since 2013-10-9 
 *
 * com.pudp.controller.ComponentController.java
 *
 */

@Controller
@RequestMapping(value="/")
public class ComponentController {

    /**
     * 跳转到首页视图层
     *
     * @author <a href='mailto:dennisit@163.com'>Cn.pudp(En.dennisit)</a> Copy Right since 2013-10-9 下午12:54:54
     *                
     * @param request
     * @param response
     * @return
     */
    @RequestMapping(value={"index","index.html"},method={RequestMethod.GET,RequestMethod.POST})
    public ModelAndView windexPage(HttpServletRequest request, HttpServletResponse response){
        return new ModelAndView("main/index");
    }
}

 

程序首次运行结果:

因为我们默认的资源文件为日文,所以展示日语版.

 

当我们点击韩语版本的话,即可将系统的国际化资源设定为韩语,效果图如下
