文档介绍：中文摘要
现今网络技术日趋成熟，网上购物正悄然兴起并正在被广大消费者迅速接受。网上购物系统在此期间应运而生，它通过网络服务器为分布在全国各城市的顾客提供购买商品的服务。从销售商来看，由于在价格上省去了实体店铺的租金、水电、人工等成本，网上购物的商品价格更低，提高了销售商的竞争力。从顾客购买过程来看，网上购物能够降低搜寻成本，便于消费者对产品的挑选和价格比较。
网上购物系统的主要内容是，一方面让销售商把商品发布于网络，一方面让消费者通过网络来完成商品的交易。系统总体分成前台和后台两大模块，前台是用户模块，后台是管理员模块。实现的功能，首先系统向用户列出网站的商品信息。其次当顾客登录网上购物系统后，为每个用户分配一个购物车，用户选择商品后，商品会被放入购物车。再次，用户确认购物车信息，点击提交生成订单。最后，管理员对订单进行处理，即完成一次商品交易。
系统实现按照MVC设计模式。采用JSP技术作视图层，Struts技术作控制层，Hibernate,JDBC技术作模型层。采用MVC设计模型，增加了系统的可拓展性与可维护性，便于开发的补充，维护。
