<?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">

<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>
