摘要

现如今先进科学技术高速发展，计算机技术已经被社会的各个领域广泛应用。随着计算机技术和通信技术的迅猛发展，互联网的规模也逐步增大，互联网的元素也随之逐渐增加，可以利用其发展通信，也可以利用其进行商业用途，可以在互联网上进行出售、收购、宣传等操作，从而使得互联网逐渐成为当今社会上必不可少的元素，而网站就是这个里很庞大的元素之一。

现如今,校园二手交易系统是商业贸易中的一条非常重要的道路，可以把其从传统的实体模式中解放中来，网上购物可以为消费者提供巨大的便利。通过校园二手交易系统这个平台，可以使用户足不出户就可以了解现今的流行趋势和丰富的商品信息，为用户提供了极大的方便，校园二手交易系统的主要功能包含：商品类别管理、商品的信息管理、订单管理、用户的管理等。网站分为管理员、会员用户这二种用户平台。校园二手交易系统主要使用目前JSP中最流行的SSM框架和Eclipse编辑器、MYSQL数据库设计并实现的。实现了一个校园二手交易系统网站。能够让广大消费者体验到网上平台订餐的乐趣，为网上购物提供了一个管理高效的、决策科学化、安全有效的电子商务平台。

一、开发技术介绍

• SSM
• JavaScript
• HTML/CSS
• MySQL

二、功能介绍

通过软件的需求分析已经获得了系统的基本功能需求。根据面向对象的不同系统分为前台普通用户界面和后台管理界面。系统功能结构如下图所示。
