Struts 国际化的一个完整例子（转）

来源：互联网发布：恐怖小说推荐知乎编辑：程序博客网时间：2024/04/30 11:27

学习程序最好的方法是看一个实例，这是我做的一个实例，虽然简单了些，但却包括了struts国际化的一些知识：

第一步：建立工程（略）

第二步：加入struts相关的JAR包，还有加载TOMCAT服务器（我的MYECLIPSE为3.2.2 ,TOmCat为5.5）其它版本我没试过！

第三步：建立系统所需要的包：如我的为

com.action.OwnerAction.java负责处理业务逻辑（代码见下面）

com.actionform.OwnerForm.java负责接受请求（同上）

另外先在这里建立资源文件，即ApplicationResource.properties,ApplicationResource.source,ApplicationResource_en.properties,ApplicationResource_zh_CN.properties

第四步，配置 web.xml与struts-config.xml

web.xml代码如下

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
>

    </taglib>
    <taglib>

    </taglib>

      <taglib-location>/WEB-INF/struts-logic.tld</taglib-location>

    </taglib>
    <taglib>
      <taglib-uri>/WEB-INF/struts-nested.tld</taglib-uri>
      <taglib-location>/WEB-INF/struts-nested.tld</taglib-location>
    </taglib>

<servlet>
    <servlet-name>action</servlet-name>
    <servlet-class>com.base.AppBaseServlet</servlet-class>
    <init-param>
      <param-name>config</param-name>
      <param-value>/WEB-INF/struts-config.xml</param-value>
    </init-param>
    <init-param>
      <param-name>debug</param-name>
      <param-value>2</param-value>
    </init-param>
    <load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>action</servlet-name>
    <url-pattern>*.do</url-pattern>
</servlet-mapping>
</web-app>
struts-config.xml代码如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">

<struts-config>
    
    <form-beans>
        <form-bean name="ownerForm" type="com.actionform.OwnerForm">

        </form-bean>

    </form-beans>

    
    <global-exceptions />

    
    <global-forwards>
        <forward name="failure" path="/failure.jsp" />

    </global-forwards>

    
    <action-mappings>
        <action

            input="owner.jsp"
            name="ownerForm"
            path="/owner"
            type="com.action.OwnerAction"
            parameter="formAction">
            <forward name="owner"   path="/index.jsp" />
            <forward name="success" path="/success.jsp" />
        </action>

    </action-mappings>
    <message-resources parameter="ApplicationResources" />

</struts-config>

红色为关键代码

第五步，建立Owner.jsp文件

<%@ page contentType="text/html;charset=utf-8" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean"%>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"%>
<html:html locale="true">
<head>   <meta name = "Generator" content = "Easy Struts Xslt generator for Eclipse (http://easystruts.sf.net).">   <title>Struts Form for ownerForm</title>   <script language="javascript">      function changeLanguage(language) {          if(language == "en") {              document.all("language").value = "en";          } else {              document.all("language").value = "cn";          }          document.forms[0].submit();      }   </script> </head>
<body>
<html:form action="/owner">
<input type="hidden" name="formAction" value="changeLanguage">
<input type="hidden" name="language">
<bean:message key="owner.greet" /> : <html:select property="greet">
         <html:option value="">请选择</html:option>
         <html:option value="Mr.">Mr.</html:option>
         <html:option value="Miss.">Miss.</html:option>
         <html:option value="Mrs.">Mrs.</html:option>
</html:select><html:errors property="greet"/></br>

     <bean:message key="owner.name" /> : <html:text property="name"/><html:errors property="name"/></br>
     <bean:message key="owner.address" /> : <html:text property="address"/><html:errors property="name"/></br>
     <bean:message key="owner.email" /> : <html:text property="email"/><html:errors property="name"/></br>
     <bean:message key="owner.tel" /> : <html:text property="tel"/><html:errors property="name"/></br>
     <html:submit property="submit" value="Submit"/>
        <html:reset value ="Reset"/>
     <input type="button" name="langEn" value="英文版" onclick="changeLanguage('en')">
     <input type="button" name="langCn" value="中文版" onclick="changeLanguage('cn')">
     </html:form>
</body>
</html:html>

第六步，建立index.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%>">

    <title>我的首页</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">

</head>

<body>
     <br>
    <%out.print(session.getAttribute("username")); %>
</body>
</html>
第七步：建立actionform

package com.actionform;

import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionMapping;
import javax.servlet.http.HttpServletRequest;

/**
* OwnerForm.java created by EasyStruts - XsltGen.
* http://easystruts.sf.net
* created on 10-09-2004
*
* XDoclet definition:
* @struts:form name="ownerForm"
*/
public class OwnerForm extends ActionForm {

// --------------------------------------------------------- Instance Variables

/** Email property */
private String email;

/** Greet property */
private String greet = "Mr.";

/** Address property */
private String address;

/** Tel property */
private int tel = 0;

/** Name property */
private String name;
// --------------------------------------------------------- Methods

public String getGreet() {
return greet;
}

public void setGreet(String greet) {
this.greet = greet;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}
public String getAddress() {
return address;
}

public void setAddress(String address) {
this.address = address;
}
public String getEmail() {
return email;
}

public void setEmail(String email) {
this.email = email;
}
public int getTel() {
return tel;
}

public void setTel(int tel) {
this.tel = tel;
}

}

第八步：建立action

package com.action;

//Created by Xslt generator for Eclipse.
//XSL : not found (java.io.FileNotFoundException: (Bad file descriptor))
//Default XSL used : easystruts.jar$org.easystruts.xslgen.JavaClass.xsl

import com.actionform.*;

import java.util.Locale;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import org.apache.struts.Globals;
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.actions.DispatchAction;
import com.actionform.*;

/**
* OwnerAction.java created by EasyStruts - XsltGen.
* http://easystruts.sf.net
* created on 10-09-2004
*
* XDoclet definition:
* @struts:action path="/owner" name="ownerForm" input="/owner.jsp" validate="true"
* @struts:action-forward name="/success.jsp" path="/success.jsp"
*/
public class OwnerAction extends Action {

public ActionForward execute(ActionMapping actionMapping,
            ActionForm actionForm,
            HttpServletRequest servletRequest,
            HttpServletResponse servletResponse) {
OwnerForm form = (OwnerForm)actionForm;
HttpSession session=servletRequest.getSession();
session.setAttribute("username",form.getName());
System.out.println(form.getName());


return(actionMapping.findForward("owner"));
}
}
第九步：也是很关键的一步，没有这步你运行也许成功，但都是乱码

cmd中执行native2ascii -encoding gb2312 ApplicationResources.source ApplicationResources_zh_CN.properties。

ApplicationResources.source :代码如下

owner.greet=称呼
owner.name=姓名
owner.address=地址
owner.email=电子邮件
owner.tel=联系电话

ApplicationResources_zh_CN.properties代码如下：

owner.greet=/u79f0/u547c
owner.name=/u59d3/u540d
owner.address=/u5730/u5740
owner.email=/u7535/u5b50/u90ae/u4ef6
owner.tel=/u8054/u7cfb/u7535/u8bdd
你只需在struts-config.xml中做如下配置 <message-resources parameter="ApplicationResources" />
你所在国家的计算机就会主动找到你所在国家的字节码。

OK！希望对初学都有所帮助，因为没人帮助过我，实在。。。
