基于J2EE的新沙港网上客户服务系统分析与设计

1基于J2EE的新沙港网上客户服务系统分析与设计2摘要本文是针对一个实际的项目——基于J2EE的新沙港网上客户服务系统的研究。首先简要介绍了电子商务及电子商务系统的相关理论，并且通过理论分析得出了网上客户服务系统是新沙港电子商务解决方案中的重要部分的结论。企业应用系统的开发一直面临着重大挑战，J2EE的出现使问题迎刃而解，本文在分析J2EE优势的基础之上，进一步介绍了J2EE的体系结构和核心技术。本文在充分的理论研究之后，利用结构化方法对新沙港的现有客户服务流程进行了分析，并提出了新系统的逻辑模型。根据系统的需求分析，对系统进行了设计。在设计的基础上进一步叙述了系统实现的主要内容及系统开发过程中的关键技术，包括远程IC卡读卡及货物情况查询模块的实现方案。该系统现已基本完成，正在新沙港进行使用，使用期间反映良好，一定程度的提高了客户的满意程度。关键字:港口客户服务J2EE电子商务EJB3AbstractThisdissertationemphasizesonarealproject,thedevelopmentofXinShaPortInternetCustomerService.Firstly,thisdissertationintroducese-commerceande-commercesystemandrelevanttheorybriefly.Inaconclusion,InternetCustomerServiceSystemisanimportantandvividpartofe-commerceSystem.Therearemanychallengesintheprocedureofdevelopingenterpriseapplication.WhenJava2PlatformEnterpriseEditionestablished,J2EEhasresolvedmanydifficulties.OnthebasisofadvantageofJ2EE,thisdissertationalsointroducesJ2EEstructureandcoretechnologies.Afterdeeplytheorystudying,thisdissertationanalyzesexistingoperationprocedureintheformofstructuredmethod.Andbuildupanewsystemoperationprocedure.Throughrequirementanalysis,thedissertationalsodesignsnewsystem.Onthebasisofdesign,thisdissertationstatessystemmainachievementsandkeytechnologies,includingremoteICcardbeingreadandthemethodofcargoinformationqueryingpart.Thissystemisalmostfinished.WhenitisbeingtestedinXinSha,whichimprovescustomersatisfactionandwell-thought-of.KeyWords：PortCustomerServiceJ2EEe-commerceEJB4目录第一章绪论........................................................................................................................11.1课题研究的背景.......................................................................................................11.2课题的现实意义.......................................................................................................21.3论文的体系结构.......................................................................................................2第二章电子商务系统及J2EE概述..................................................................................32.1电子商务系统概述...................................................................................................32.1.1电子商务....................................................32.1.2电子商务系统................................................42.1.3网上客户服务系统是港口电子商务系统的重要组成部分............42.2J2EE概述..................................................................................................................52.2.1企业级应用..................................................52.2.2J2EE的优势..................................................72.2.2J2EE体系结构................................................92.2.3J2EE技术核心..............................................11第三章新沙港网上客户服务系统的需求分析..............................................................133.1新沙港网上客户服务系统的需求背景.................................................................133.1.1新沙港务公司信息化建设方案简介.............................133.1.2新沙港电子商务系统实施的“四步走”战略.....................183.2新沙港现有客户服务的业务流程分析..................................................................183.3新系统逻辑方案的建立..........................................................................................203.3.1新系统的业务流程分析.......................................203.3.2新系统的数据流程分析.......................................23第四章新沙港网上客户服务系统的设计......................................................................274.1系统功能概述.........................................................................................................274.2系统功能的设计.....................................................................................................284.2.1系统总体结构设计...........................................284.2.2系统模块设计...............................................294.3数据库的设计.........................................................................................................314.3.1数据库表的设计.............................................3154.3.2数据库自动编号功能的实现...................................34第五章系统实现的主要内容及关键技术......................................................................365.1利用远程IC卡读卡完成客户登录的实现............................................................365.2货物信息查询的实现.............................................................................................41第六章结束语..................................................................................................................446.1全文总结.................................................................................................................446.1.1系统的特色.................................................446.1.2论文的主要工作.............................................446.2进一步研究的问题.................................................................................................446.2.1系统安全...................................................456.2.2利用XML和数字签名实现网上合同签约.........................47致谢......................................................................................................................................54参考文献....................................................................................................................
