校园二手交易平台的设计与实现
摘 要
本系统采用JSP/J2EE技术，使用Java编程语言编写的一套校园网二手交易平台软件。本系统采用的是最近几年流行的B/S开发模式，是以互联网方式运行的。服务器端只需要安装本系统，而客户端用户只要可以上网，就可以非常方便快捷的通过浏览器访问系统，浏览和发布二手交易信息，免去了传统的C/S模式下复杂的安装、配置、维护等操作。同时由于使用面向对象的Java语言，所以本系统也具有Java语言的面向对象、与平台无关、安全性高、稳定性高、多线程等特性，以及Java语言对网络编程技术的支持。使得本系统具有很高的使用价值。
本系统主要功能有用户管理，商品信息查询及管理，留言信息的查询及管理，还有后台管理员相应的管理功能等。系统的主要设计思路是先确定好系统所需要的数据字典并在数据库中设计好相应的数据库，然后根据MVC的思想，依次设计好基础类，业务类，实现控制的servlet和实现显示的jsp。
系统开发主要分为三个部分，使用JavaBeans处理业务逻辑,JSP+HTML+JavaScript进行界面处理，并且配置了Servlet，以及通过JDBC处理对SQL Server 2008数据库的访问。

The Design and Realization of Campus Network Secondhand Merchandise System
ABSTRACT
This system is a set of platform software of the campus-wide system secondhand transaction. It adopts the JSP/J2EE technique, and programmed with Java programming language. It also adopts the B/S development mode, which is based on Web and popularize in recent years. It runs in internet ways. Only when the server install this system and the client can visit it, browse and release some secondhand conveniently and speedily when they go on-line. And so it dispenses with such operation as the complicated installing, installment and support in traditional C/S mode. At the same time the use of object-oriented Java language, so the system also has a Java object-oriented language, and platform-independent, high security, high stability, multi-threading features,the Java language’s support to the network programming technique makes the system have high practical value.
The main functions of the system user management, product information inquiry and management, query and manage voice messages, as well as the background corresponding management functions administrators. System's main design idea is to determine a good system needs data dictionary and database design is the appropriate database, and then the idea MVC, followed by a good basis for the design class, busin
