2.welcome.jsp 同时也是struts基本标签的用法
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

My JSP 'welcome.jsp' starting page
This is my JSP page.
亲爱的用户欢迎您:
下面是struts2一般标签的测试内容：
----111111111--------s:include-----------
---222222222---------s:param-and s:include----------
-----33333333-------s:property--and push---------
param的作用是：为其他标签如include，bean提供参数
下面没有提供value参数：为默认值
--4444444444----------s:set标签-----------
------555555555------s:text标签-----------
Mr Smith
------6666666666------s:if s:elseif s:else标签-----------

备注：项目实现的功能比较多，不太适合初学者。struts 架构 、struts链接数据库mysql、struts一般标签的使用（下一遍日志会记录）、简单的体现了SSH的一种开发模式。
