struts2的國際化（中英文切換）
阿新 • • 發佈：2018-12-19
國際化Internationalization的首末字元I和N之間字元數是18，簡稱I18N。
“國際化”是指一個應用程式在執行時，能夠根據客戶端請求所來自國家或地區語言的不同，而顯示不同的語言介面。
要求：Struts2框架搭建成功。
1. 專案截圖
2.建立資原始檔：
2.1 messages_en_US.properties（英文）
2.2 messages_zh_CN.properties（中文）
3. 新建檢視層 jsp頁面
3.1 index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <%@ taglib prefix="s" uri="/struts-tags" %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>My JSP 'index.jsp' starting page</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> <!-- 區域性定義使用哪一種國際化語音 --> <s:i18n name="message"> <s:text name="check"></s:text>: <a href="changeLanguage.action?request_locale=zh_CN"><s:text name="chinese"></s:text></a> <a href="changeLanguage.action?request_locale=en_US"><s:text name="english"></s:text></a> <br/> <form action="<%=basePath%>t1" method="post"> <table> <tr> <td><s:text name="login.username"/></td> <td><input type="text" name="user.userName"/></td> </tr> <tr> <td><s:text name="login.password"/></td> <td><input type="text" name="user.password"/></td> </tr> <tr> <td colspan="2"><input type="submit" value="<s:text name="login.btn"/>"/></td> </tr> </table> </form> </s:i18n> </body> <ml>
3.2 show.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> </head> <body> 使用者名稱：${requestScope.name}<br/> 密碼：${requestScope.pwd} </body> </html>
4. 編寫action
4.1 區域設定Action ChangeLanguageAction.java
package com.hnpi.action;
public class ChangeLanguageAction {
public String execute(){
return "success";
}
}
4.2 提交表單Action RegisterAction.java
package com.hnpi.action; public class RegisterAction { private String name; private String sex; public String getName() { return name; } public void setName(String name) { this.name = name; } public String getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } public String execute(){ return "success"; } }
5. 配置攔截器 (進行語言選擇的處理)
struts.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<package name="default" extends="struts-default">
<action name="t1" class="com.hnpi.action.RegisterAction" method="execute">
<result name="success">/show.jsp</result>
</action>
<action name="changeLanguage" class="com.hnpi.action.ChangeLanguageAction">
<result>/index.jsp</result>
</action>
</package>
</struts>
6. web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
