1.创建一个Dynamic Web Project —— Structs2_100_Introduction

2.将struts2/struts-2.3.16.1/apps/struts2-blank/WEB-INF/web.xml 复制到 Structs2_100_Introduction/WebContent/WEB-INF 目录下

3.将struts2/struts-2.3.16.1/apps/struts2-blank/WEB-INF/lib 下的所有jar包复制到/Structs2_100_Introduction/WebContent/WEB-INF/lib 目录下

4.将struts2/struts-2.3.16.1/apps/struts2-blank/WEB-INF/src/java 下的structs.xml文件复制到/Structs2_100_Introduction/src 目录下

6.在Structs2_100_Introduction/WebContent 下创建 Hello.jsp

<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
    
    <title>HelloStruts2</title>
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">    
	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">

	<!--
	<link rel="stylesheet" type="text/css" href="styles.css">
	-->
  </head>
  
  <body>
    Hello Struts2 <br>
  </body>
</html>

7. 运行Structs2_100_Introduction ，然后在地址栏的地址后加上hello ,与structs中的action对应

加上hello后地址变为： http://localhost:8080/Structs2_101_Introduction/hello

运行后显示Hello Structs
