1、 ActionMethod：Action执行的时候并不一定要执行execute方法，可以在配置文件中配置action的时候用“method”属性来指定执行哪个方法，也可以在url地址中动态指定（动态方法调用DMI）Struts.xml文件的配置：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<constant name="struts.devMode" value="true" />
<package name="user" extends="struts-default" namespace="/user">
<action name="userAdd" class="com.bjsxt.struts2.user.action.UserAction" method="add">
<result>/user_add_success.jsp</result>
</action>
<action name="user" class="com.bjsxt.struts2.user.action.UserAction">
<result>/user_add_success.jsp</result>
<result name="delete">/user_delete_success.jsp</result>
</action>
</package>
</struts>
Index.jsp页面的内容：
<?xml version="1.0" encoding="GB18030" ?>
<%@ page language="java" contentType="text/html; charset=GB18030"
pageEncoding="GB18030"%>
<% 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=GB18030" />
<title>Insert title here</title>
</head>
<body>
<a href="<%=context %>/user/userAdd">添加用户</a><br />
<a href="<%=context %>/user/user!add">添加用户</a><br />
<a href="<%=context %>/user/user!delete">删除用户</a><br />
</body>
</html>
UserAction的内容：
package com.bjsxt.struts2.user.action;
import com.opensymphony.xwork2.ActionSupport;
public class UserAction extends ActionSupport {
public String add() {
return SUCCESS;
}
public String delete(){
return "delete";
}
}
