1.引言
因为最近有个英国的项目要求中英文切换，又由于我们开发是用struts+hibernate的，所以我们就把原先做两个版本的构思抛掉，就用struts的国际化处理方案。
2.资料
首先，我们要准备两份配置文件中文和英文的
中文:ApplicationResources_zh_CN.properties
英文:ApplicationResources_en.properties (千万不要用默认的ApplicationResources.properties myeclipse自动生成，可能会不成功，我起先就是因为这个怎么都不行的，呵呵！)
3.准备开始
1) ApplicationResources_zh_CN.properties的内容
#zh_CN
username=纯冰
2)ApplicationResources_en.properties的内容
#en
username=chunkyo
3)一个action
/*
* Generated by MyEclipse Struts
* Template path: templates/java/JavaClass.vtl
*/
package com.lan.struts.action;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.Globals;
import java.util.Locale;
/**
* MyEclipse Struts
* Creation date: 02-07-2007
*
* XDoclet definition:
* @struts.action validate="true"
*/
public class ChangeLanguageAction extends Action {
/*
* Generated Methods
*/
/**
* Method execute
* @param mapping
* @param form
* @param request
* @param response
* @return ActionForward
*/
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
// TODO Auto-generated method stub
String lan=request.getParameter("lan");
if(lan.equals("1"))
{
request.getSession().setAttribute(Globals.LOCALE_KEY,Locale.CHINA);
}
else if(lan.equals("0"))
{
request.getSession().setAttribute(Globals.LOCALE_KEY,Locale.ENGLISH);
}
else
{
request.getSession().setAttribute(Globals.LOCALE_KEY,Locale.CHINA);
}
return mapping.findForward("index");
}
}
4)一个页面
<%@ page language="java" pageEncoding="utf-8"%>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-bean" prefix="bean" %>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html" %>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-logic" prefix="logic" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html:html locale="true">
<head>
<html:base />
<title><bean:message key="username"/></title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body>
<html:link page="/changeLanguage.do?lan=0">English</html:link>
<html:link page="/changeLanguage.do?lan=1">Chinese</html:link>
<bean:message key="username"/>
</body>
</html:html>
4)配置文件(struts-config.xml)
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">
<struts-config>
<data-sources />
<form-beans />
<global-exceptions />
<global-forwards >
<forward name="index" path="/index.jsp" />
</global-forwards>
<action-mappings >
<action path="/changeLanguage" type="com.lan.struts.action.ChangeLanguageAction" />
</action-mappings><message-resources parameter="com.lan.struts.ApplicationResources" />
</struts-config>
5)结果
1。默认
http://localhost:8080/lan/
EnglishChinese 纯冰
2。英文
http://localhost:8080/lan/changeLanguage.do?lan=0
EnglishChinese chunkyo
3。中文
http://localhost:8080/lan/changeLanguage.do?lan=1
EnglishChinese 纯冰
6)结论
用struts做国际化处理 多国语言处理很方便 呵呵！
