struts2 validation入门

好长时间没做struts2项目了，最近在做的时候在带select的数据校验这块居然卡壳了，所以写了个小例子，收藏起来。

用到的jar：

1. commons-fileupload-1.2.1.jar
2. commons-io-1.3.2.jar
3. freemarker-2.3.15.jar
   
4. jstl.jar
5. ognl-2.7.3.jar
6. standard.jar
7. struts2-core-2.1.8.1.jar
8. xwork-core-2.1.6.jar

jsp页面代码：

<%@ page language="java" contentType="text/html; charset=UTF-8"	pageEncoding="UTF-8"%>
<%@taglib prefix="s" uri="/struts-tags"%>
