摘 要

随着经济全球化的进一步发展，以往的传统销售模式正在被进一步蚕食。人们不愿去固定的场所，交易时间长，效率低。网店作为经济全球化的产物，适应市场为买家和卖家提供了高效率，低成本的销售模式。

网店是不需要店铺门面租赁费，可以在最短时间内提供最新的产品，因为不需要将商品运输到固定的店铺。网店为商检节约了大笔的运输费，场地租赁费等大额成本。同时买家也以最短时间购买到最新产品。它是的人们足不出户购买商品。网络资源是共享且廉价的，这使得互联网市场的门槛极低，市场无比广阔。给供需双方都带来利益和方便。

本设计仿照各大主流电商做出了类似的网店系统。供卖家后台发布，管理商品，前台展示商品以供买家购买。卖家可以根据市场上架任意产品并对产品加以包装介绍。同时买家也可以方便安全购买商品。

本设计采用freemaker进行网页页面设计，使用MVC设计模式和开源框架struts。后端数据库MYSQL。并引入Redis缓存技术以加快页面访问速度。

ABSTRACT

With the further development of economic globalization, the traditional traditional sales model is being further eroded. People do not want to go to a fixed place, long trading time, low efficiency. Shop as a product of economic globalization, to adapt to the market for buyers and sellers to provide a highly efficient, low-cost sales model.

It is the people who buy goods at home. Network resources are shared and cheap, which makes the Internet market threshold is very low, the market is very broad. To both supply and demand benefits and convenience.

The design modeled on the major mainstream electricity business to make a similar shop system. For the seller background release, management of goods, the front show goods for buyers to buy. The seller can be based on the market any products and packaging products introduced. At the same time buyers can also facilitate the safe purchase of goods.

The design uses freemaker for web page design, using MVC design patterns and open source framework struts. Backend database MYSQL. And the introduction of Redis cache technology to speed up page access.
