校园二手商品交易平台的设计与实现摘要摘要：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。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-ODBC桥接器处理对SQLServer2000数据库的访问。关键词：JSP；JavaBeans；Java；B/S；AbstractThissystemisasetofplatformsoftwareofthecampus-widesystemsecondhandtransaction.ItadoptstheJSP/J2EEtechnique,andprogrammedwithJavaprogramminglanguage.ItalsoadoptstheB/Sdevelopmentmode,whichisbasedonWebandpopularizeinrecentyears.Itrunsininternetways.Onlywhentheserverinstallthissystemandtheclientcanvisitit,browseandreleasesomesecondhandconvenientlyandspeedilywhentheygoon-line.Andsoitdispenseswithsuchoperationasthecomplicatedinstalling,installmentandsupportintraditionalC/Smode.Atthesametime,itusestheJavalanguagewhichtowardstheOOP(object-orientedprogramming).SothesystemhasthespecificpropertyoftowardingOOP,irrelevantwiththeplatform,theJavalanguage’ssupporttothenetworkprogrammingtechniquemakesthesystemhavehighpracticalvalue.Thesystemdevelopmentisdividedintothreeparts.ThatisusingJavaBeanstoprocessbusinesslogic;usingJSP+HTML+JavaScriptandServlettoprocessinterface;andvisitingtheSQLServer2000databasethroughJDBC-ODBCBridge.Keywords:JSP;JavaBeans;Java;B/S;目录1.绪论...................................................................................................................................-1-1.1.课题背景...............................................................................................................-1-1.2.电子商务的起源....................................................................................................-3-1.2.1.电子商务的意义.........................................................................................-4-1.3.可行性分析................................................................................错误!未定义书签。1.4.研究意义...............................................................................................................-5-2.校园二手商品交易网.......................................................................................................-7-2.1.系统需要解决的主要问题...................................................................................-7-2.2.校园二手商品交易网站的基本特征...................................................................-8-2.3.本文的主要贡献及组织结构.............................................................................-10-2.3.1.本文的主要贡献.......................................................................................-11-2.3.2.论文的结构.................................................................................................-5-3.交易网开发分析.............................................................................................................-12-3.1.校园交易需求分析.............................................................................................-12-3.1.1.具体校园市场现状分析...........................................................................-12-3.1.2.论文术语描述...........................................................................................-13-3.2.可行性分析.........................................................................................................-13-3.2.1.经济可行性...............................................................................................-13-3.2.2.环境可行性...............................................................................................-14-3.2.3.校园商品支付可行性...............................................................................-15-3.3.市场定位分析.....................................................................................................-15-4.系统概述及数据库设计.................................................................................................-17-4.1.系统目标.............................................................................................................-17-4.2.系统开发设计原则.............................................................................................-17-4.2.1.完整性原则...............................................................................................-17-4.2.2.相关性原则...............................................................................................-17-4.2.3.适应性原则...............................................................................................-17-4.2.4.可靠性原则...............................................................................................-18-4.2.5.经济性原则...............................................................................................-18-4.3.系统功能分析.....................................................................................................-18-4.4.系统数据库设计.................................................................................................-18-4.4.1.数据库设计的原则...................................................................................-18-4.4.2.数据库设计的步骤...................................................................................-
