一、index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

</html>

二、header.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ page import="java.util.*"%>

<div class="return"><a href="#">設爲首頁</a> | <a href="#">添加到收藏夾</a>
</div>

</div>

<ul>

   <li style="margin-left:25px;_margin-left:17px;"><a href="index.jsp" >首   頁</a></li>
   <li class="bor"><a href="showCar.jsp">查看購物車</a> </li>

   <li class="bor"><a href="showCar.jsp">查看購物車</a> </li>
           </ul>

</div>

三、footer.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
     <div class="clear"></div>

        <div class="footer">

       <div class="footer_left"></div>

</div>

四、content.jsp頁設計

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

五、left.jsp頁

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<div class="person">
<img src="p_w_picpaths/personal.gif">

        </div>
       <ul>


        <li><a href="notice.jsp?nid=11" target= _blank>公告測試6
        <span>3-20</span></a></li>
        <li><a href="notice.jsp?nid=11" target= _blank>公告測試6
        <span>3-20</span></a></li>
        <li><a href="notice.jsp?nid=11" target= _blank>公告測試6
        <span>3-20</span></a></li>
        <li><a href="notice.jsp?nid=11" target= _blank>公告測試6
        <span>3-20</span></a></li>



        </ul>
</div>

        </div>
       <ul class="list_con">

        <li><a href="content.jsp?type=1         ">電腦        </a></li>

        <li><a href="content.jsp?type=2         ">手機        </a></li>

        <li><a href="content.jsp?type=3         ">電動車       </a></li>

        <li><a href="content.jsp?type=4         ">洗衣機       </a></li>

        <li><a href="content.jsp?type=5         ">相機        </a></li>


        </ul>
</div>
<div class="contant_us">
  <img src="p_w_picpaths/contant_us.gif">
      <table style="margin:10px 0 0 10px;">
            <tbody><tr>
                <td width="30%" valign="top">地址：</td>
                    <td>東營市東營區黃河路569號魯班公寓</td>
                </tr>
                <tr>
                <td>郵編：</td>
                    <td>257100</td>
                </tr>
                <tr>
                <td>電話：</td>
                    <td>0546-8060345</td>
                 </tr>

六、right.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<div class="current">
<p>當前位置：首頁>所有商品</p>
</div>

七、詳細信息頁

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

2、前臺顯示商品信息

一、數據庫 goods表添加picture字段，ntext類型

二、Goods.java類，添加String picture屬性及相應的get、set方法

三、GoodsDAO的list方法修改，添加語句

Goods g=new Goods();
   g.setGid(rs.getInt("gid"));
   g.setName(rs.getString("name"));
   g.setPrice(rs.getFloat("price"));
   g.setNum(rs.getInt("num"));
   g.setPicture(rs.getString("picture"));//將picture信息保存到Bean中
   ls.add(g);

四、前臺right.jsp頁，實現顯示商品信息

<div class="right_down">

   <% GoodsDAO dao=new GoodsDAO();
        LinkedList<Goods> gs=dao.list();
        for(Goods g:gs){

//循環顯示商品信息
%>

<%=g.getName() %></a></li> <li>價格：<%=g.getPrice() %></li> <li>庫存數量：<%=g.getNum() %> </ul> </div> <%} %>
