<s:property value="%{#session.mySessionAttribute}" />
Session Scope Attribute
<s:property value="%{#session.mySessionAttribute}" />
Request Scope Attribute
<s:property value="%{#request.myRequestAttribute}" />

<s:property value="%{#myContextParam}" />
等等……
---------------------------------华丽的demo分割线---------------------------------------------
首先导入标签库！
<%@ taglib uri="/struts-tags" prefix="s2" %>
放在request作用域的数据：
request.setAttribute("products", products);
猥琐的HTML代码！。。。。。。。
获取request数据！
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
request.setAttribute("basePath",basePath);
%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="/struts-tags" prefix="s2" %>
