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...................................................................................................................................-0-.课题背景.....................................................................................................................-0-.电子商务的起源.........................................................................................................-2-电子商务的意义..................................................................................................-3-`.可行性分析......................................................................................错误!未定义书签。.研究意义.....................................................................................................................-4-2.校园二手商品交易网.......................................................................................................-6-.系统需要解决的主要问题.........................................................................................-6-.校园二手商品交易网站的基本特征.........................................................................-7-.本文的主要贡献及组织结构.....................................................................................-9-本文的主要贡献................................................................................................-10-论文的结构..........................................................................................................-4-3.交易网开发分析.............................................................................................................-11-.校园交易需求分析...................................................................................................-11--具体校园市场现状分析....................................................................................-11-论文术语描述....................................................................................................-12-.可行性分析...............................................................................................................-12-经济可行性........................................................................................................-12-环境可行性........................................................................................................-13-校园商品支付可行性........................................................................................-14-.市场定位分析...........................................................................................................-14-4.系统概述及数据库设计.................................................................................................-16-.系统目标...................................................................................................................-16-.系统开发设计原则...................................................................................................-16-：完整性原则........................................................................................................-16-相关性原则........................................................................................................-16-适应性原则........................................................................................................-16-可靠性原则........................................................................................................-17-经济性原则........................................................................................................-17-.系统功能分析...........................................................................................................-17-.系统数据库设计.......................................................................................................-17-数据库设计的原则............................................................................................-17-数据库设计的步骤.
