591论文网的互联网拍卖系统的设计摘要网上拍卖是新兴起的一种网上交易方式。它具有成本低廉，方式灵活，运行快捷等特点，通过Internet将拍卖活动变成每一位网民都可以加入其中的交易方式。但它在给人们带来便利的同时也带来了很多的问题。它的公平、公正、公开性受到大家的关注。其可靠性和安全性更是大家关心的问题。这就要求不仅要在系统的设计上做到公平合理，也要在信息的传输上做到安全可靠，以构建一个公平又安全的交易平台。本文构建了一个基于B/S模式的网上拍卖系统，为买卖双方搭建了一个灵活自由并且安全可靠的交易平台。本文着重论述了系统的模块设计、数据流程和功能实现。其功能包括用户注册、登陆、网上拍卖、网上竞价、商品搜索、购买者对商品的评价、购买者留言、后台数据库管理、拍卖者信用度的统计等功能。包括如何运用JAVA、JavaScript、JSP等关键技术建立网上购物系统,并在web服务器上配置SSL以保证敏感信息的安全传输。关键词：网上拍卖；JSP；SSL；竞价591论文网’snotonlyrequiredafairnessandrationalityonthedesignofsystem,butalsokeepstheinformationsecurityandreliabilitywhentransferringtoconstructaplatformoffairnessandsecurity.ThesystemdesignsanauctionsystembasedonthemodeofB/S,andproposesaflexibleandreliableenvironmentfortradeservice.Thethesisputmostwordsondesignofmodule,dataflowandrealizationoffunction,includingclientregister,login,auction,competition,commodityresearching,commentandcrediblestatforpersononauction.ThethesisalsodiscusseshowtobuildupanonlineauctionsystemwithJava,JavaScript,JsptechniquesandconfiguretheSSLtoensurethesecuretransmissionofsensitiveinformationonthewebserver.Keywords:OnlineAuction;JSP;SSL;Competitive591论文网目录论文总页数：28页1引言..............................................................................................................................................12绪论..............................................................................................................................................12.1本系统设计的意义..........................................................................................................12.2网上拍卖的起源..............................................................................................................12.3我国网上拍卖的现状......................................................................................................22.4网上拍卖的营销方式......................................................................................................23系统总体设计..............................................................................................................................23.1系统运行环境要求...........................................................................................................23.2需求分析..........................................................................................................................33.2.1需要实现的功能及功能模块...............................................................................33.2.2数据流程图...........................................................................................................43.2.3功能模块设计.......................................................................................................53.3系统E-R图......................................................................................................................73.4系统数据逻辑结构...........................................................................................................84系统具体实现...............................................................................................................................94.1开发系统的语言与工具...................................................................................................94.2拍卖商品功能................................................................................................................104.3竞购商品功能.................................................................................................................124.4查询拍卖情况功能.........................................................................................................154.5商品搜索功能.................................................................................................................164.6信用度统计功能.............................................................................................................184.7对商品评价功能.............................................................................................................204.8购物车功能.....................................................................................................................215系统的数据传输安全保证........................................................................................................215.1数据传输的安全性要求................................................................................................215.2SSL协议提供的服务.....................................................................................................215.3ssl的工作原理.............................................................................................................215.4Tomcat配置SSL（Windows环境）...........................................................
