所有的学习我们必须先搭建好Struts2的环境（1、导入对应的jar包，2、web.xml，3、struts.xml）
第一节：Struts2 标签简介
Struts2 自己封装了一套标签，比JSTL 强大，而且与Struts2 中的其他功能无缝结合。
当然Strust2 标签的内容很多，随着版本的升级，标签和属性越来越多。我们要掌握好核心标签及了解其他标签。
根据功能可以分为：数据标签，控制标签，界面标签，其他标签。
第二节：Struts2 数据标签
Property 标签：输出OGNL 表达式的值；
Set 标签：设置变量；
Bean 标签：定义javaBean 对象；
Date 标签：日期标签；
Debug 标签：调试标签；
Url&a 标签：超链接标签；
Include 标签：动态包含标签；
