基于JSP的网上拍卖系统的分析与设计(含源文件)

基于JSP的网上拍卖系统的分析与设计基于JSP的网上拍卖系统的分析与设计摘要随着Internet的日益普及和电子商务的发展,网上拍卖迅速成为一种非常活跃的C2C电子商务模式。文中详细介绍了JSP技术以及分析了基于JSP建立网上拍卖系统的技术手段，深入探讨了如何利用JavaBean技术实现与SQLServer2000数据库连接的方法。系统采用界面与业务逻辑分离的三层结构设计，将页面显示交由JSP控制，把业务逻辑封装在JavaBean中，提高了系统的安全性、可维护性、重用性和可扩展性。系统的注册模块应用了AJAX技术，不但实现了无刷新提交数据而且减轻了服务器的负担;通过缓存系统配置信息减轻数据库服务器的压力;对系统后台模块使用双重密码校验和验证码技术，进一步提升了系统的完全系数，使它能即使在复杂的网络环境也能以最小的系统开销正常运行。关键词：电子商务，C2C，JavaBean，AJAX基于JSP的网上拍卖系统的分析与设计ABSTRACTWiththeincreasingpopularizationofInternetandthedevelopmentofelectroniccommerce,thenetauctionquicklybecomesonekindofactiveC2Celectroniccommerce.ThearticledetailedlyintroducesaJSPtechniqueandanalyzesthetechniquemeansofbuildinganetauctionsystembasedonJSP,thendeeplydiscusseshowtouseJavaBeantechniquetobuildconnectionwithSQLServer2000databases.Thesystemusesthreestructuraldesignswhichthecontactsurfaceandtheservicelogicseparates,thepagedemonstratedhandsoverbytheJSPcontrol,theservicelogicsealinJavaBean,enhancedthesystemsecurity,themaintainability,hasentrustedwithheavyresponsibilitythenatureandmaytheextension.ThesystemregistrationmodulehasappliedtheAJAXtechnology,notonlyrealizedtonotrenovatessubmitsthedatamoreoverbutlightentheserverburden;Ithasreducedthedatabaseserverthroughthebuffersystemdispositioninformationthepressure;Thesystermusesdualpasswordverificationandtheconfirmationcodetechnologyinthesystembackstagemodule,hasfurtherpromotedthesystemcompletecoefficient,andenablesitworkbythesmallestsystemexpensesnormaloperationinthecomplexnetworkenvironment.Keywords:ElectronicCommerce，C2C，JavaBean，AJAX基于JSP的网上拍卖系统的分析与设计目录第一章绪论..............................................................................................................................11.1系统应用背景与功能......................................................................................................................11.2系统预览.........................................................................................................................................21.3系统特点.........................................................................................................................................3第二章系统要解决的技术问题..............................................................................................42.1连接SQLServer2000...................................................................................................................42.2安装jspSmartUpload文件上传组件............................................................................................42.3JSP中文乱码问题的处理.............................................................................................................52.4页面无刷新地提交数据................................................................................................................6第三章系统设计......................................................................................................................83.1系统设计思想..................................................................................................................................83.1.1功能的独立化、模块化。.................................................................................................83.1.2三层架构设计思想.............................................................................................................83.1.3系统实现的功能.................................................................................................................93.2系统层次概框图............................................................................................................................103.3系统模块详细介绍.........................................................................................................................113.3.1前台模块..............................................................................................................................113.3.2后台模块..............................................................................................................................11第四章数据库设计................................................................................................................134.1数据库需求分析............................................................................................................................134.2数据库逻辑设计............................................................................................................................13第五章详细设计....................................................................................................................195.1系统JavaBean的实现..................................................................................................................195.1.1用户出价、商品、短信Bean的功能分析.......................................................................205.1.2数据库连接类的功能分析.................................................................................................20基于JSP的网上拍卖系统的分析与设计5.1.3管理员登录类的功能分析.................................................................................................215.1.4商品搜索类的功能分析.....................................................................................................215.1.5
