Spring MVC国际化和整合Freemarker的国际化

spring 版本4.1.2 

书写国际化文件

messages_en_US.properties  英语

loginFrom.username=login username
loginFrom.password=login password
locale.selection = Language Selection

messages_zh_CN.properties 中文简体

loginFrom.username=\u767B\u9646\u7528\u6237\u540D
loginFrom.password=\u767B\u9646\u5BC6\u7801
locale.selection = \u8BED\u8A00\u9009\u62E9

messages_zh.properties 中文

loginFrom.username=\u767B\u9646\u7528\u6237\u540D zh
loginFrom.password=\u767B\u9646\u5BC6\u7801 zh
locale.selection = \u8BED\u8A00\u9009\u62E9 zh

Spring MVC+jsp国际化

Spring MVC 配置文件中加入一下配置

 	
	
	
 	
       	
			
				
				messages/messages
			
		
		
        
    

Jsp页面中加入Spring MVC标签

<%@taglib uri="http://www.springframework.org/tags" prefix="spring" %>

书写表达式

Spring MVC + Freemarker国际化

首先获取spring.ftl  获取位置在spring-webmvc-4.1.2.RELEASE.jar  包下面的 \org\springframework\web\servlet\view\freemarker\spring.ftl

使用 

<@spring.message code="loginFrom.username"/> 向页面输出国际化信息

配置不变自己加入整合Freemarker的配置（配置下面的LocaleController动态修改配置）

<#import "/common/spring.ftl" as spring/>
login.ftl 


	<@spring.message code="locale.selection"/>
	English
	中文简体
	中文
	


	<@spring.message code="loginFrom.username"/>

	<@spring.message code="loginFrom.password"/>

动态修改语言类型

添加LocaleController控制器

package com.lwp.controller;
import java.io.IOException;
import java.util.Locale;
import javax.servlet.http.Cookie;
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.bind.annotation.ResponseBody;
import org.springframework.web.servlet.LocaleResolver;
import org.springframework.web.servlet.i18n.CookieLocaleResolver;
import org.springframework.web.servlet.support.RequestContext;

@Controller
@RequestMapping("/locale")
public class LocaleController {
	
	@RequestMapping("/login")
	public String login(){
		return "/login";
	}
	
	
	
	@Autowired
    private LocaleResolver localeResolver; 
	
	@RequestMapping("/change")
	@ResponseBody
	public String setSession(HttpServletRequest request,HttpServletResponse response,String locale){
		try {
			//这两个配置任选其一,可以不加if判断删除其一 我这里是任意配置session或者cookie修改配置后不需变代码
			//
			if(localeResolver instanceof org.springframework.web.servlet.i18n.SessionLocaleResolver){
				String[] localeArr = locale.split("_");
				
				Locale l = null;
				if(localeArr.length == 1){
					l = new Locale(localeArr[0]);  
				}else{
					l = new Locale(localeArr[0],localeArr[1]);
				}
				localeResolver.setLocale(request, response, l); 
				//request.getSession().setAttribute(SessionLocaleResolver.LOCALE_SESSION_ATTRIBUTE_NAME, l); //功能同上
				System.out.println("SessionLocaleResolver");
			}
			//
			if(localeResolver instanceof org.springframework.web.servlet.i18n.CookieLocaleResolver){
					Cookie cookie = new Cookie(CookieLocaleResolver.LOCALE_REQUEST_ATTRIBUTE_NAME, new Locale(locale).toString());
					cookie.setMaxAge(5);
					response.addCookie(cookie);
					response.flushBuffer();
					System.out.println("CookieLocaleResolver");
				
			}
		} catch (Exception e) {
			e.printStackTrace();
			return "error";
		}
		return "success";
		
	}
	
	/**
	 * 后台根据国际化编码返回信息
	 * @param response
	 * @param request
	 */
	@RequestMapping("returnMessage")
	public void returnMessage(HttpServletResponse response,HttpServletRequest request){
		RequestContext rc = new RequestContext(request);
		String w = rc.getMessage("loginFrom.username"); //根据locale不同返回不同语言
		try {
			response.getWriter().write(w);
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
