Struts 2中如何用一个action调用多个方法，避免每一个方法写一个action的繁琐之处

================================================这个是打开首页的一个jsp页面===================================================

<%@ 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" onclick="return window.location='add'"/>

<input type="button" value="删除" onclick="return window.location='delete'"/>



<input type="button" value="添加_1" onclick="return window.location='userManage!add'"/>

<input type="button" value="删除_1" onclick="return window.location='userManage!delete'"/>

</body>

</html>

=============================================这个是Action==================================================================

package org.demo.struts;

import com.opensymphony.xwork2.ActionSupport;

public class UserManage extends ActionSupport {

/** 这个是第一种用method方法明确指定调用的方法

public String add() {

return SUCCESS;

}

public String delete() {

return SUCCESS;

}

*/

//下面这个这用DMI动态执行方法

public String add() {

return "add_success";

}

public String delete() {

return "delete_success";

}

}

================================================这个是struts.xml 中的配置=====================================================

<?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="UserManage" namespace="/" extends="struts-default">





<action name="userManage" class="org.demo.struts.UserManage">

<result name="add_success">add.jsp</result>

<result name="delete_success">delete.jsp</result>

</action>

</package>

</struts>

========================================这里有两个add.jsp ，和delete.jsp页面执行是分别执行action中的add()，delete()中的跳转页面==================
