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 Selectionmessages_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\u62E9messages_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
<!-- 国际化 -->
<!-- xx?locale=en_US 自动修改语言的拦截器的拦截器
<mvc:interceptors>
<bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor" />
</mvc:interceptors>
-->
<bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver"/>
<!--
<bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver">
<property name="cookieName" value="locale" />
<property name="cookieMaxAge" value="604800" />
<property name="defaultLocale" value="zh" />
</bean>
-->
<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basenames">
<list>
<!-- src/messages -->
<value>messages/messages</value>
</list>
</property>
<!-- 如果没有找到国际化key值 默认输出key -->
<property name="useCodeAsDefaultMessage" value="true" />
</bean>
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:message code="loginFrom.username"/> <spring:message code="loginFrom.password"/>
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）
<script type="text/javascript" src="/18n/js/jquery-1.7.2.js"></script>
<#import "/common/spring.ftl" as spring/>
<h1>login.ftl </h1>
<hr/>
<select id="selection">
<option><@spring.message code="locale.selection"/></option>
<option value="en_US">English</option>
<option value="zh_CN">中文简体</option>
<option value="zh">中文</option>
</select><hr/>
<from>
<@spring.message code="loginFrom.username"/><input type="text"/><br/>
<@spring.message code="loginFrom.password"/><input type="text"/><br/>
</from>
<hr/>
<script type="text/javascript">
$(function(){
$("#selection").change(function(){
var locale = $(this).val();
$.post("/18n/locale/change",{locale:locale},function(data){
if(data == "success"){
window.location.href="/18n/locale/login"
}else{
alert("错误");
}
},"html")
});
})
</script>
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
//<bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver"/>
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");
}
//<bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver"/>
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();
}
}
}
