本文深入解析了JSP页面如何通过通配符配置实现对不同Action的统一管理，以及在Struts2框架下如何利用通用配置符优化配置文件，简化配置过程。

这个是文件的一命名主看Student开头的

============================首先看首页就是接按钮==================================

<%@ 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>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">

</head>

<body>

     
     
    <input type="button" value="添加学生" onclick="return window.location='Student_add'"/>
        <input type="button" value="删除学生" onclick="return window.location='Student_delete'"/>

</body>
</html>

===========================然后是Action==========================

package org.demo.struts;

import com.opensymphony.xwork2.ActionSupport;

public class StudentAction extends ActionSupport {

public String add() {
return "add_success";
}

public String delete() {
return "delete_success";
}
}

===================然后是怎么在sturt.xml中使用通用配置符配置=========================

<?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.devMode" value="true"/>

   
   
<package name="studentAction" namespace="/" extends="struts-default">
    <action name="*_*" class="org.demo.struts.{1}Action" method="{2}">
     <result name="{2}_success">{1}_{2}_success.jsp</result>
    </action>
</package>

</struts>
