1.新建web Project：Struts2_ActionWildcard
2.新建以下的文件：
项目图：

StudentAction.java
TeacherAction.java
struts.xml
WebRoot:
index.jsp
Studentadd_success.jsp
Studentdelete_success.jsp
Teacher_add_success.jsp
Teacher_delete_success.jsp
3.以下为项目中各文件的代码：
（1）struts.xml
代码：
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE struts PUBLIC 3 "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" 4 "http://struts.apache.org/dtds/struts-2.0.dtd"> 5 6 <struts> 7 <constant name="struts.devMode" value="true" /> 8 <package name="actions" extends="struts-default" namespace="/actions"> 9 <action name="Student*" class="com.bjsxt.struts2.action.StudentAction" method="{1}"> 10 <result>/Student{1}_success.jsp</result> 11 </action> 12 13 <action name="*_*" class="com.bjsxt.struts2.action.{1}Action" method="{2}"> 14 <result>/{1}_{2}_success.jsp</result> 15 <!-- {0}_success.jsp --> 16 </action> 17 </package> 18 </struts>
（2）StudentAction.java
代码：
1 package com.bjsxt.struts2.action; 2 3 import com.opensymphony.xwork2.ActionSupport; 4 5 public class StudentAction extends ActionSupport { 6 public String add() { 7 return SUCCESS; 8 } 9 public String delete() { 10 return SUCCESS; 11 } 12 13 }
------------------------------------------------------------------------------------
------------------------------------------------------------------------------------
(3)TeacherAction.java
代码:
1 package com.bjsxt.struts2.action; 2 3 import com.opensymphony.xwork2.ActionSupport; 4 5 public class TeacherAction extends ActionSupport { 6 public String add() { 7 return SUCCESS; 8 } 9 10 public String delete() { 11 return SUCCESS; 12 } 13 14 15 }
------------------------------------------------------------------------------------
------------------------------------------------------------------------------------
(4) index.jsp
代码：
<?xml version="1.0" encoding="UTF-8" ?>
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<% String context = request.getContextPath(); %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Insert title here</title>
</head>
<body>
使用通配符，将配置量降到最低<br />
<a href="<%=context %>/actions/Studentadd">添加学生</a>
<a href="<%=context %>/actions/Studentdelete">删除学生</a>
<br />
不过，一定要遵守"约定优于配置"的原则
<br />
<a href="<%=context %>/actions/Teacher_add">添加老师</a>
<a href="<%=context %>/actions/Teacher_delete">删除老师</a>
</body>
</html>
------------------------------------------------------------------------------------
------------------------------------------------------------------------------------
(5)Studentadd_success.jsp
代码：
<?xml version="1.0" encoding="UTF-8" ?>
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@taglib uri="/struts-tags" prefix="s" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Insert title here</title>
</head>
<body>
Student Add Success!
</body>
</html>
如Studentadd_success.jsp页面案例所示，
在Studentdelete_success.jsp页面中输出Student Delete Success!
Teacher_add_success.jsp页面中输出Teacher Add Success!
Teacher_delete_success.jsp页面中输出Teacher Delete Success!
Struts2 ActionWildcard（通配符配置）约定优于配置
