JSP网上书店开发完整实例(含完整源代码)

完整的简单jsp网上书店详细实例计算机web编程jsp毕业论文、考试复习资料必备其中包括的详细需求、业务分析、数据库、源代码我们使用JSP和Java Bean来构建一个网上书店。

介绍的例子可以分成两大部分，第一部分是普通程序，用于客户在网上选购图书，第二部分是管理程序，用于在服务器端处理客户的定单。

客户端程序由以下几个部分构成：default.jsp：会员登录界面(首页)；checklogon.jsp：检测登录代码和密码是否一致，根据由JavaBean返回的结果显示不同的信息。

BuyerBean：会员的合法性检验所用的Bean；booklist.jsp：给登录会员显示当前书店中可供选择的图书；addcart.jsp：将所选的图书加入购物车；shoppingcart.jsp：查看购物车的内容；本例的数据库采用Access（.MDB数据库），对数据库的访问采用便于理解的JDBC-ODBC方式，在使用本例前先在本地数据库建立一个ODBC数据源：bookstore。

设置步骤如下：（1）在开始->设置->控制面版（Win98、NT4.0）中选取“数据源（ODBC）”；在Win 2000 Professional和Server中分别位于“开始->设置->控制面版->管理工具”和“开始->程序->管理工具”下。

（2）启动“数据源（ODBC）”配置程序，界面如图15-1所示。

图15-1 ODBC数据源管理界面（3）在图15-1中“系统DSN”选项下单击“添加”按钮，来添加一个系统的数据源（DSN），则出现如图15-2所示数据源驱动程序选择界面：图15-2 数据源驱动程序选择界面（4）在图15-2中选择“Microsoft Access Driver (*.mdb)”单击“完成”加载Access数据库的驱动，则出现如图15-3所示数据库ODBC安装界面：图15-3 数据库ODBC安装界面（5）在图15-3中单击“选择（S）…”按钮，启动一个类似资源管理器的界面来选择数据库，如图15-4所示，在图15-4所示的界面中选择bookstore.mdb。

一、需求分析；
网上书店系统主要是实现网上选书、购书、产生订单等功能的系统。

一个典型的网上商城一般都需要实现商品信息的动态提示、购物车管理、客户信息注册登录管理、订单处理等模块。

根据网上书店的基本需求，本系统需要完成的具体任务如下：
1)书图查询: 当客户进入网上书店时，应该在主页面中分类显示最新的书目信息，以供客户选择所需图书，同时也应该提供按照图书名称，或者作者信息快速查询所需书目信息的功能。

2)购物车管理：当客户选择购买某图书产品时，应该能够将对应图书信息，如：价格、数量记录到对应的购物车中，并允许客户返回书目查询页面，选择其它商品，并添加到购物车中，当对应的购物订单生成后，应该能够自动清除以生成订单的购物车
中的信息。

3)订单处理：对应客户购买图书商品信息的需求，在确定了所购图书商品的价格、数量等信息后，提示用户选择对应的送货方式及付款方式，最终生成对应的订单记录，以便于网站配货人员依据订单信息进行后续的出货、送货的处理。

4)会员注册：为了能够实现图书商品的购买，需要管理客户相关的联系方式、送货地点等相关的信息。

二、系统设计内容；
1)采用人机对话的操作方式，界面设计美观友好、信息查询灵活、方便、快捷、准确、数据存储安全可靠。

2)全面展示商城内所有商品。

3)为顾客提供一个方便、快捷的商品信息查询功能。

采用模糊查询查询数据。

4)会员能够随时修改自己的会员资料。

5)实现网上购物。

6)查看商城内的公告信息。

7)用户随时都能够查看自己的订单。

8)对用户输入的数据，系统进行严格的数据检验，尽可能排除人为的错误。

9)系统最大限度地实现了易维护性和易操作性。

10)系统运行稳定、安全可靠。

三、系统逻辑设计；
根据实现功能不同将网站分为了在线购书子系统和后台管理子系统。

1）在线购书子系统为消费提供了在线浏览图书，订购图书的平台。

属于前台展示部分的设计。

具体功能如下：
用户登陆网站浏览图书。

用户在主页或我的帐户中注册成为网站的会员。

只有网站的会员才能在网站购买图书。

用户能够经过分类浏览，书目推荐，新书推荐，书目查询的方式选择喜爱的图书。

用户选择图书提交订单完成订购。

2）后台管理子系统为书店管理员提供了管理网络书店的平台。

属于后台管理部分的设计。

具体功能如下：
注册会员的管理，并经过会员的消费记录更改的会员的等级，不同等级的会员享受不同的购书折扣待遇。

图书类别的管理，图书的管理。

经过添加，修改，删除对图书类别进行管理。

在类别下添加图书记录，对图书的名称，出版单位，媒体推荐，内容简介等详细信息进行添加，修改等管理。

订单的管理，查询会员提交的订单并处理。

处理已经送货的订单使之对书店的图书销售记录书店库存信息实时修改。

书店公告信息的管理添加书店的公告信息使消费者及时了解书店的最新动态。
