注：本文系作者在看了浪曦的风中叶老师的struts2视频的个人总结，希望能帮助广大struts2的初学者。
此处为了简便起见和知识重复性的避免，暂不考虑类型转换问题。 第一步：（这一步和其他一样，这里从简）依旧是新建一个web project，命名为checkxml，导入struts2必须的包。在src目录下新建struts.xml，修改web.xml文件。 第二步：将index.jsp改名为reg.jsp（这个不是必须的，事实上也没有必要，此处只是为了便于称呼）。Input.jap的代码如下Jsp代码 
<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<%@ taglib prefix="s" uri="/struts-tags"%>

很好啊，学过但是忘 了。思路很清晰再看一遍就会了
