Struts做的一个国际化

来源：互联网发布：易语言sql语句生成器编辑：程序博客网时间：2024/05/18 03:42

1.首先是用struts做一个jsp页面locale.jsp,代码如下:
<%@ page contentType="text/html;charset=UTF-8" %>
<%@ include file="taglibs.jsp" %>
<html:html locale="true">
<head><title>国际化</title></head>
    <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>
<body>
    <html:form action="/regist/customers_regist">
    <input type="hidden" name="formAction" value="changeLanguage">
    <input type="hidden" name="language">
     <input type="button" name="langEn" value="English" onclick="changeLanguage('en')">
     <input type="button" name="langCn" value="中文版" onclick="changeLanguage('cn')">
    </html:form>
</body>
</html:html>
其中引用了一个taglibs,jsp页面,这个页面主要是引用了标签必须用到的.tld文件
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%-- Listing of all of the taglibs that we reference in this application --%>
<%-- Struts provided Taglibs --%>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>

2.创建一个Action:LocaleAction.java,代码如下:
/**
* <p>application name: LocaleAction</p>
* <p>application describing: 此类为实现国际化的action</p>
* <p>copyright: Copyrigtht 2006 东软成都Java定制班版权所有</p>
* <p>company: neusoft</p>
* <p>time: 2006.11.05</P>
*
* @author ZhongHui
* @version ver 2.1
* @email:2031120607@smail.ccniit.com
*
* */
package com.neusoft.tis.control.action;

import java.util.Locale;

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

import org.apache.struts.Globals;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.actions.DispatchAction;

public class LocaleAction extends DispatchAction {

public ActionForward changeLanguage(
   ActionMapping mapping,
   ActionForm form,
   HttpServletRequest request,
   HttpServletResponse response) {

  String language = request.getParameter("language");
  if (language.equals("en"))
  {
   request.getSession().setAttribute(
     Globals.LOCALE_KEY, Locale.ENGLISH);
  }

  else
  {
   request.getSession().setAttribute(
     Globals.LOCALE_KEY, Locale.CHINESE);
  }

  return mapping.findForward("customers_regist");
}
}

3.因为我是为一个客户注册进行的国际化,所以用到的是CustomerAdminsForm.java,代码如下:
/**
* <p>application name: CustomerAdminsForm</p>
* <p>application describing: 此类为前台页面与数据库数据交换。用于设置与获取相关变量</p>
* <p>copyright: Copyrigtht 2006 东软成都Java定制班版权所有</p>
* <p>company: neusoft</p>
* <p>time: 2006.11.05</P>
*
* @author Yichao Zeng
* @version ver 2.1
* @email:2032120714@smail.ccniit.com
*
* */
package com.neusoft.tis.control.form;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;

public class CustomerAdminsForm extends ActionForm {

private static final long serialVersionUID = -1L;

private String loginUser = null; //登录ID

private String customerID = null; //客户ID(消费者)

private String passwd = null; //密码

private String email = null; //电子邮箱(供找回密码使用)

private String userStatus = null; //用户状态(包括:停用、正常)

private String question = null; //找回密码问题

private String answer = null; //找回密码答案

private String sex = null; //性别

private String birthDay = null; //出生日期

private String lastLoginDate = null; //上次登录时间

private String closer = null; //关闭人

private String closeDate = null; //关闭日期

private String remark = null; //备注

public String getAnswer() {
return answer;
}

public void setAnswer(String answer) {
this.answer = answer;
}

public String getBirthDay() {
return birthDay;
}

public void setBirthDay(String birthDay) {
this.birthDay = birthDay;
}

public String getCloseDate() {
return closeDate;
}

public void setCloseDate(String closeDate) {
this.closeDate = closeDate;
}

public String getCloser() {
return closer;
}

public void setCloser(String closer) {
this.closer = closer;
}

public String getCustomerID() {
return customerID;
}

public void setCustomerID(String customerID) {
this.customerID = customerID;
}

public String getEmail() {
return email;
}

public void setEmail(String email) {
this.email = email;
}

public String getLastLoginDate() {
return lastLoginDate;
}

public void setLastLoginDate(String lastLoginDate) {
this.lastLoginDate = lastLoginDate;
}

public String getLoginUser() {
return loginUser;
}

public void setLoginUser(String loginUser) {
this.loginUser = loginUser;
}

public String getPasswd() {
return passwd;
}

public void setPasswd(String passwd) {
this.passwd = passwd;
}

public String getQuestion() {
return question;
}

public void setQuestion(String question) {
this.question = question;
}

public String getRemark() {
return remark;
}

public void setRemark(String remark) {
this.remark = remark;
}

public String getSex() {
return sex;
}

public void setSex(String sex) {
this.sex = sex;
}

public String getUserStatus() {
return userStatus;
}

public void setUserStatus(String userStatus) {
  this.userStatus = userStatus;
}

public void reset(ActionMapping mapping, HttpServletRequest request) {

  loginUser = null;
  customerID = null;
  passwd = null;
  email = null;
  userStatus = null;
  question = null;
  answer = null;
  sex = null;
  birthDay = null;
  lastLoginDate = null;
  closer = null;
  closeDate = null;
  remark = null;
}

public ActionErrors validate(ActionMapping mapping,
            HttpServletRequest request) {

ActionErrors errors = new ActionErrors();
return errors;

}

4.接下来修改struts-config.xml文件
在<action-mappings>下边添加如下代码：
<action
      attribute="customerAdminsForm"
      input="/locale.jsp"
      name="customerAdminsForm"
      path="/regist/customers_regist"
      scope="request"
      parameter="formAction"
      type="com.neusoft.tis.control.action.LocaleAction">
      <forward name="customers_regist" path="/regist/customers_regist.jsp" />
</action>
在这里用到了一个customers_regist.jsp界面，代码如下：
<%@ page contentType="text/html;charset=UTF-8"%>
<%@ include file="../taglibs.jsp" %>

<html:html locale="true">
<head>
<title><bean:message key="regist.customers.titile" /></title>
</head>
<link href="<%=request.getContextPath()%>/css.css" rel="stylesheet" type="text/css">
<body>
<html:errors/>
<html:javascript formName="customerAdminsForm" />
<html:form action="/customers_regist" onsubmit="return validateCustomerAdminsForm(this)">
<table width="779" border="1">
    <tr>
      <td><table cellSpacing=2 cellPadding=0 width="100%"

这个页面是放在regist文件佳下边的，各位可以根据自己的需要修改xml文件的路径，里面都用到了相

对应的资源文件的东西，接下来将会讲到。

5.接下来讲一讲用到的资源文件
Resources.properties这个是默认的，当什么都没选择时，会根据浏览器的语言选择这个资源文件，

我默认的是中文，内容如下：
################# regist/customers_regist.jsp

regist.customers.titile = \u4f1a\u5458\u6ce8\u518c

regist.submit = \u63d0\u3000\u4ea4\u3000\u8868\u3000\u5355
另外有个中文的Resources_zh_CN.properties,内容和上边一样，不多说了，当点击中文按钮时就会用

到这个文件。
还有一个Resources_en.properties，内容都是自己根据中文意思翻译的，有很多地方翻译不够准备，

还请见谅，内容如下：
######### regist/customers_regist.jsp

regist.customers.titile = Leaguer Regist
regist.choose.loginuser = Choose Login Name
regist.choose.loginuser.notice = Please use English and Chinese(GB)
regist.choose.loginuser.name = Login Name\uff1a
regist.choose.loginuser.submit = Check Login Name
regist.flow = Regist step\uff1a1.choose login name - 2.regist success
regist.flow.notice = Login name\uff1a4-16 of charactor(include 4\u300116)or 2-8 of

Chinese\uff0c please use lower-case of

English\u3001Chinese\u3001number\u3001underline\uff0c Don't all of number

regist.passwd = Input password\uff1a
regist.repasswd = Again input password\uff1a
regist.passwd.notice = Password letter partition lower-case and upper-case.4-16 place

(include 4\u300116),only use English and number.

regitst.passwd.search.notice = Query answer\uff1a over 6 of letter\u3001number or 3 of

Chinese.If you fogot password,you can find for it.Please must remember.
regitst.passwd.search.question = Password query question\uff1a
regitst.passwd.search.question.option0 = --Please choose--
regitst.passwd.search.question.option1 = what is my pet name\uff1f
regitst.passwd.search.question.option2 = who is my best friend\uff1f
regitst.passwd.search.question.option3 = what is my favorite color\uff1f
regitst.passwd.search.answer = Password query answer\uff1a

regist.sex = Sex\uff1a
regist.sex.man = Man
regist.sex.woman = Woman

regist.email = E-Mail\uff1a

regist.submit = Submit form

另外还需要在struts-config.xml文件里配置一下
<message-resources parameter="com.neusoft.tis.system.locale.Resources" />
在这里，我的默认资源文件是放到这个下边的，各位请根据自己放置的位置填写。另外还需要注意的

是对资源文件的命名，英文是Resources_en.properties，中文是Resources_zh_CN.properties，前面

的Resources可以自己随便取，后边要遵循规范来做，否则不能找到。

程序演示如下:
