一、使用 NetBeans 8.0.2 建立 struct2.x 框架环境
新建Java web项目，在框架选择的时候，勾选structs2。点击完成，即会生成名为 helloworld 的项目。
struct2.x 框架的工作流程：
三、分析利用structs2框架生成的 helloworld 项目
<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<title><s:text name="HelloWorld.message"/></title>
</head>
<body>
<h2><s:property value="message"/></h2>
<h3>Languages</h3>
<ul>
<li>
<s:url id="url" action="HelloWorld">
<s:param name="request_locale">en</s:param>
</s:url>
<s:a href="%{url}">English</s:a>
</li>
<li>
<s:url id="url" action="HelloWorld">
<s:param name="request_locale">es</s:param>
</s:url>
<s:a href="%{url}">Espanol</s:a>
</li>
</ul>
</body>
</html>
在上面代码中，元素<s:url>的 action 属性值必须是 struct.xml 配置过的请求名，即HelloWorld。<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<!--使用example.xml配置文件-->
<include file="example.xml"/>
<!-- Configuration for the default package. -->
<package name="default" extends="struts-default">
</package>
</struts>
<?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>
<!--创建名为example的包，该包必须继承默认包-->
<package name="example" namespace="/example" extends="struts-default">
<!--配置helloworld请求action-->
<action name="HelloWorld" class="example.HelloWorld">
<result>/example/HelloWorld.jsp</result>
</action>
</package>
</struts>
元素<action>中属性name表示请求的名称（HelloWorld），class表示处理该请求的具体执行类（example.HelloWorld）。/*

package example;
import com.opensymphony.xwork2.ActionSupport;
/**
* <code>Set welcome message.</code>
*/
public class HelloWorld extends ActionSupport {
public String execute() throws Exception {
setMessage(getText(MESSAGE));
return SUCCESS;
}
/**
* Provide default valuie for Message property.
*/
public static final String MESSAGE = "HelloWorld.message";
/**

private String message;
/**

public String getMessage() {
return message;
}
/**

public void setMessage(String message) {
this.message = message;
}
}
HelloWorld.java文件就是对应名为 HelloWorld 的action。上面代码，实现了相应的业务逻辑组件。
