1、第一个Struts2程序

为了让我们以后开发方便，我们需要配置struts.xml的dtd的头，这样在编写struts.xml文件中可以有提示！

操作如下：

（1）打开myeclipse→window→Preferences→输入xml→XML→XML Catalog→Add→点击File System找到struts-2.1.7.dtd文件→在Key:输入-//Apache Software Foundation//DTD Struts Configuration 2.0//EN→勾选Specify alternative web address→在复选框下的输入框输入：http://struts.apache.org/dtds/struts-2.0.dtd→ok→ok

1.创建如下项目目录结构

2.在WebRoot下窗前index.jsp文件

 1 <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
 2 <%@taglib uri="/struts-tags" prefix="s" %>
 3 <%
 4 String path = request.getContextPath();
 5 String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
 6 %>

10   <head>
11     <base href="<%=basePath%>">
