---------------------------------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" %>
