摘要：本文介绍了网上零食销售系统的整个开发过程，采用国内认准的B2C商城建站系统模式，并按照现有的购物系统的现状而设计开发的网络买卖平台。
本文主要阐述的了整个系统的完成过程，模拟了一个具备卖家，买家和管理员的网络交易系统。而本平台对不同的用户进行了细致的分划。对各个模块进行了功能上的丰富和优化。利用这些模块之间的交互完成整个物品的交易过程，为消费者和商家提供方便快捷的商务体验。说明书中已经简单的引述了电子商务的历史和现状，同样也介绍了该系统需要完成的功能，对整个项目的完成流程和进行时间进行了详细的规划。最后，对网上零食销售系统的前台应用软件进行了一些简要介绍。
网上零食销售系统以JSP为主要的网页开发技术。利用B/S三层架构作为开发的基础框架，出于对系统的维护性，耦合性和安全性的考量，利用JavaBean对项目中关键部分进行封装的处理。数据库采用了后期维护十分便捷的MYSQL5.0数据库，其拥有的用可视化工具可以对字段进行快速准确的修改。

The design and implementation of online snack sales system
Abstract：This article describes the online snack sales system throughout the development process, the use of domestic B2C mall to build the system model, and in accordance with the existing shopping system, the current design and development of network trading platform.
This paper focuses on the completion of the whole system, simulates a network transaction system with sellers, buyers and administrators. But this platform carries on the detailed division to the different user. The modules are enriched and optimized in function. Use the interaction between these modules to complete the transaction process of the whole article, providing consumers and businesses with convenient and quick business experience. The manual has briefly quoted the history and current situation of e-commerce, and also introduced the functions that the system needs to complete. It also gives a detailed plan for the completion process and the time of the whole project. Finally, the online snack sales system of the front application software are briefly introduced.
Online snack sales system to JSP as the main web development technology. The B/S three tier architecture is used as the basic framework of the development, and the encapsulation of the key parts of the system is processed by using JavaBean for consideration of system maintainability, coupling and security. The database adopts the MYSQL5.0 database which is convenient for later maintenance, Its own visual tools allow for rapid and accurate changes to the field.
