创建一个简单的Struts2程序

读者看过前一篇文章后环境就搭建好了，但想要运行起来还有很多工作，废话不多说，咱们开始吧！！！（1）启动Myeclipse创建一个Web项目HelloWorld

（2）将struts2的相关JAR包粘贴到Web项目的lib目录下（3）在src目录下新建一个名为struts.xml的配置文件（4）在Struts.xml中加入如下代码（包为默认）<?xml version="1.0" encoding="UTF-8"?><?xmi 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="default" extends="struts-default"><action name="tag" class="com.TagAction"><result >/result.jsp</result></action></package></struts>（5）修改web.xml如下<?xml version="1.0" encoding="UTF-8"?><web-app version="2.4"xmlns="http://java.sun.com/xml/ns/j2ee"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <filter><filter-name>struts2</filter-name><filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class></filter><filter-mapping><filter-name>struts2</filter-name><url-pattern>/*</url-pattern></filter-mapping><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list></web-app>（6）在src下新建Helloworld类package com;import com.opensymphony.xwork2.Action;import com.opensymphony.xwork2.ActionSupport;public class HelloWorld{Private String messagepublic String getMessage() {return userBean;}public void setMessage(String message) {this.message = message;}

        public String execute() throws Exception {// TODO Auto-generated method stubreturn "success";}

(7)新建HelloWorld.jsp,代码如下：
