1，在專案 HeadFirstStruts2chapter02 中，新建HelloWorldAction.java,繼承ActionSupport類，
package com.cruise.action;
import com.opensymphony.xwork2.ActionSupport;
public class HelloWorldAction2 extends ActionSupport{
private String name ;
public
return name;
}
public void setName(String name) {
this.name = name;
}
@Override
public
System.out.println("struts2的預設的方法執行了");
return "success";
}
}
2，修改struts.xml檔案，
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"
<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>
struts>
3，測試，同上一節。
4，通過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">
name：<input type="text" name="name"/><input type="submit" value="提交">
</form>
</body>
</html>
5，測試post方式：
點選提交
