Struts2国际化示例-优快云博客

1：在Src下建立两个属性文件（注：两个文件的key值要相同）

其中内容如下

RES_en_US.properties

username=username
password=password
welcome={0} welcome to JAVA world{1}
submit=submit

RES_zh_CN.properties（里面放的是中文对应的unicode编码）

username=\u7528\u6237\u540D
password=\u5BC6\u7801
welcome={0} \u6B22\u8FCE\u6765\u5230JAVA\u4E16\u754C{1}
submit=\u63D0\u4EA4

2 index.jsp的核心代码

<%@ taglib uri="/struts-tags" prefix="s"%>

<body>
<a href="lang?request_locale=zh_CN">中文</a>
<a href="lang?request_locale=en_US">English</a>
   <s:form action="show" method="post">
       ${message}
          <s:textfield name="username" key="username" ></s:textfield>//username是属性文件中的key值

//JSP为占位符传参（后续加上去的运行截图显示时没有这段代码）

           <s:text name="welcome">
          <s:param>晓波哥</s:param>
          <s:param>学习</s:param>
          </s:text>

<s:submit key="submit"></s:submit>
</s:form>
</body>

3action类

（1）中英文切换对应的action

package org.action;

import com.opensymphony.xwork2.ActionSupport;

public class LangAction extends ActionSupport {

   @Override
   public String execute() throws Exception {
       // TODO Auto-generated method stub
       return SUCCESS;
   }

}

（2）表单提交的action

package org.action;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;

public class ResAction extends ActionSupport {
   private String username;
   public String getUsername() {
       return username;
   }
   public void setUsername(String username) {
       this.username = username;
   }
   @Override
   public String execute() throws Exception {
       // action中为占位符传参
       ActionContext.getContext().put("message", this.getText("welcome",new String[]{username,"学习"})) ;//页面中有个${message}获取该值，welcome是属性文件中的key值
       return SUCCESS;
   }

}

3struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>

<constant name="struts.custom.i18n.resources" value="RES"/>
<package name="default" extends="struts-default">
       <action name="show" class="org.action.ResAction" >
               <result name="success">/index.jsp</result>
       </action>

       <action name="lang" class="org.action.LangAction" >
               <result name="success">/index.jsp</result>
       </action>
       </package>
</struts>
