基於JSP完成的“智多星”智能手機銷售網項目開發日誌
信管1171 李靜
一、系統開發
1.數據庫設計與連接
前臺用到了四張表格
user表（用戶表）
orderform表（訂單表）
mobileform表（手機信息表）
mobileclassify表（手機類型表）
2.配置文件web.xml

二、系統各個功能進行講述
1.首頁
首頁用到了樹形菜單，將原本書上的導航菜單改成了樹形菜單放在頁面的左邊，將首頁圖片從底部移動到了菜單的右邊，使得看起來會更美觀一些。
indexx.jsp
<%@ page contentType="text/html;charset=GB2312" %>
<HTML>
<HEAD>
<link rel="StyleSheet" href="dtree.css" type="text/css" />
<script type="text/javascript" src="dtree.js"></script>

</div>
<div class="zhi">

</BODY></HTML>
因爲使用了樹形菜單所以還有兩個文件，實現了菜單的樣式和動畫效果。

<br>查詢時可以輸入手機的版本號或手機名稱及價格。<br>
手機名稱支持模糊查詢。
<br>輸入價格是在2個值之間的價格，格式是：價格1-價格2<br>
例如 3987-8976
<FORM action="searchByConditionServlet" Method="post" >
<br>輸入查詢信息:<Input type=text name="searchMess"><br>
<Input type =radio name="radio" value="mobile_version">手機版本號
<Input type =radio name="radio" value="mobile_name" checked="ok">手機名稱
<Input type =radio name="radio" value="mobile_price">手機價格
