Struct2标签的分类

一、
写jsp页面的时候，在struts2中，用的是s标记，先引入标记：
<%@ taglib prefix="s"uri="/struts-tags"%>
二、
struts2的标签和1是完全不同的。
struts2的标签分为两大类：非UI标志和UI标志 struts1将标志库按功能分成HTML、Tiles、Logic和Bean等几部分
下面就介绍strut2的具体标签：
1、UI
UI标志又可以分为表单UI和非表单UI两部分。表单UI部分基本与Struts1.x相同，都是对HTML表单元素的包装。不过，Struts2.0加了几个我们经常在项目中用到的控件如：datepicker、doubleselect、timepicker、optiontransferselect等。因为这些标志很多都经常用到，而且参数也很多，要在一篇文章详细说明并非易事。
下面主要是ui标签的一些用法
form:
<s:form act<wbr>ion="exampleSubmit" method="post"enctype="multipart/form-da<wbr>ta"&gt;<br> &lt;s:submit /&gt;<br><wbr><wbr><wbr>&lt;s:reset /&gt;</wbr></wbr></wbr></wbr></wbr>

</s:form>可以上传文件的form。
textfield：
<s:textfield
