毕业设计（论文） 姓　　 名 系 别、 专 业 导 师 姓 名、职 称 完 成 时 间 摘　要：本网上购物系统是一个基于Internet,采用B2C(Business to Consumers)模式，并根据现有的网上购物系统的现状而设计开发的电子商务平台。它不但可以扩大商家的规模和市场影响力，而且可以减少企业的经营成本，提高工作效率。 本文首先介绍了网上购物系统的现状及开发背景，然后论述了系统的设计目标，系统需求和总体设计方案，较详细的论述了系统的详细设计和实现。最后，本文对网 上购物系统进行了系统检测并提出了还需要改进的问题。 本系统主要为用户提供了会员注册，购物车管理，用户资料修改等功能，为管理员提供了商品管理，用户信息管理等功能。在设计方面，本系统采用B/S三层结构，同时使用JSP技术进行动态页面的设计，从系统的安全性和代码的可重用性方面考虑，运用JavaBean对程序的关键代码进行封装。后台数据库选用My SQL数据库。 关键词：B/S结构；JavaBean；JSP； The Design of The Shop OnLine System Abstract：The system is a electronic commercial platform which has been designed according to the situation of shop online system based on Internet with B2C mode. It can not only enhance the scale of shopping centre and market influence, and can also reduce the enterprise’s running cost, improve work efficiency. The thesis has firstly introduced the practical situation and the developing background of the system. And then has described the designing goal、system need and the whole designing plan, has described the detailed design and reality of the system in detail. Finally, conclusion has been drawn about the system and problem has also been raised. The system has mainly provided users with the following functions: membership registration、shopping car management、goods search、information modify etc. It has also provided managers with goods management、customer information management、news management 、ad management and so on. It has been designed with B/S mode of three-tier structure, JSP technology in dynamic page design. Considering from the security and reusing code of the system, key codes has been secured by JavaBean technology. My SQL database has been used as the background database. Key Words: B/S structure; JavaBean; JSP ; 前　言目前在国内PHP与ASP应用最为广泛。而JSP由于是一种较新的技术，国内采用的较少。但在国外，JSP已经是比较流行的一种技术，尤其是电子商务类的网站，多采用JSP。 采用PHP的网站如新浪网（sina）、中国人（Chinaren）等,但由于PHP本身存在的一些缺点，使得它不适合应用于大型电子商务站点，而更适合一些小型的商业站点。 首先，PHP缺乏规模支持。其次，缺乏多层结构支持。对于大负荷站点，解决方法只有一个：分布计算。数据库、应用逻辑层、表示逻辑层彼此分开，而
