<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "struts-2.1.dtd" >
<struts>
	<!--
		用于标示struts的国际化，规定国际化文件要以globalMessage做为开头，如：“globalMessage_zh_CN.properties”。
		
		以下说明为有精力的同学看（可以不看）：
		也可以不要这行代码，采取属性文件的方式。具体做法是：先删除这行代码，然后在项目的src下
		建一个属性文件，名为struts.properties（注：必须取这个名字），在属性文件中键入：
		struts.custom.i18n.resources=globalMessage保存即可。
		这个等号后面的"globalMessage"是随意取的，只要取的名字与国际化属性文件的名字
		相对应即可，例如：若写"struts.custom.i18n.resources=Myi18n"那么国际化文件
		的名字就要以Myi18n开头，如中文国际化属性文件名字就应该为"Myi18n_zh_CN.properties".
	-->
	<!-- value=message.globalMessage 对应着 资源文件路径 src/message/globalMessage*.properties -->
	<constant name="struts.custom.i18n.resources" value="message.globalMessage"></constant>

	<!-- 对应com.test.action包中的loginAction类 -->
	<package name="test" namespace="/" extends="struts-default">
		<action name="loginAction" class="com.test.action.LoginAction">
			<result name="success">welcome.jsp</result>
			<result name="login">login.jsp</result>
		</action>
	</package>
</struts>

3 JAVA国际化资源配置 src/message/

globalMessage_en_US.properties

login.title=login title
login.firstname=firstname
login.lastname=lastname
login.age=age
login.submit=submit
login.info=please write {0} and {1}
login.welcome=welcome you

globalMessage_zh_CN.properties

login.title=用户登录
login.firstname=姓
login.lastname=名
login.age=年龄
login.submit=提交
login.info=请输入 {0}和{1}
login.welcome=欢迎你

4 JS国际化 WebContent/js/locale

jsLocale.jsp js资源加载jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Insert title here</title>

<script type="text/javascript" src="<%=request.getContextPath() %>/js/locale/locale_<%=request.getLocale().toString() %>.js"></script>

<script type="text/javascript">
	//js key获取函数
	function getJsLocale(key)
	{
		if (typeof(jsLocale) != 'undefined')
		{
			if (typeof(jsLocale[key]) != 'undefined')
			{
				return jsLocale[key];
			}
			else
			{
				return key;
			}				
		}
		else
		{
			return key;
		};
	}
</script>

</head>
<body>

</body>
</html>

locale_en_US.js

var jsLocale = 
{
	name : "sky",
	sex  : "man",
	info : "locale from js"
};

locale_zh_CN.js

var jsLocale = 
{
	name : "李晓峰",
	sex  : "男",
	info : "js国际化"
};

public class LoginAction extends ActionSupport
{

	@Override
	public String execute() throws Exception
	{
		// TODO Auto-generated method stub
		return super.execute();
	}
	
	/**
	 * 
	 * 手动转换Locale
	 * @return
	 * @throws Exception

	public String i18n() throws Exception 
	{
		HttpServletRequest request = ServletActionContext.getRequest();
		String language = request.getParameter("language");
		String country = request.getParameter("country");
		
		Locale locale = new Locale(language, country);
		ActionContext.getContext().setLocale(locale);
		
		getResource();
		
		return "login";
	}
	
	/**
	 * 测试手动获取资源
	 * @see [类、类#方法、类#成员]
	 */
	public void getResource()
	{
		Locale locale = new Locale("zh","CN");
		ResourceBundle bundle = ResourceBundle.getBundle("message.globalMessage",locale);
		String name = bundle.getString("login.submit");
		String name1 = bundle.getString("login.info");
		
		Object[] os = {"infi","th000"};
		
		String name11 = MessageFormat.format(name1, os);
		
		String name3 = getText("name");
		System.out.println(name);
		System.out.println(name11);
		System.out.println(name3);
	}
}
