1，在项目 HeadFirstStruts2chapter02 中，新建HelloWorldAction.java,继承ActionSupport类，
package com.cruise.action;

import com.opensymphony.xwork2.ActionSupport;

public class HelloWorldAction2 extends ActionSupport{

    private String name ;

    public String getName() {

       return name;
    }

    public void setName(String name) {

       this.name = name;
    }

@Override
public String execute() throws Exception {

       System.out.println(“struts2的默认的方法执行了”);
       return “success”;
    }
}

2，修改struts.xml文件，
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>
<package name=“suibiandingyi” extends=“struts-default”>
    <action name=“hello” class=“com.cruise.action.HelloWorldAction”>
       <result name=“success”>helloworld.jspresult>
    action>
    <action name=“hello2” class=“com.cruise.action.HelloWorldAction2”>
       <result name=“success”>helloworld.jspresult>
    action>
package>

3，测试，同上一节。

4，通过post方式提交 index.jsp 如下：
<%@ page language=“java” contentType=“text/html; charset=UTF-8”
pageEncoding=“UTF-8”%>
<!DOCTYPE html PUBLIC “-//W3C//DTD HTML 4.01 Transitional//EN””http://www.w3.org/TR/html4/loose.dtd”>
<html>
<head>
<meta http-equiv=“Content-Type” content=“text/html; charset=UTF-8”>
<title>Insert title here</title>
</head>
<body>
<form action=“hello2” method=“post”>
