基于javaEE的网上书城系统的实现及研究

1摘要随着网络的发展，基于计算机对信息管理的高效性，各种信息管理平台跃入人们的视野。其中，网上书城就是典型的信息管理系统（MIS）。本系统是基于JavaEE三层结构的B/S(Browser/Server)模型软件，包含以下三个部分：表示层、业务逻辑层和数据访问层。结合MVC框架模式的分层结构，将应用分成Model（模型）、View（视图）、Control（控制）3个部分。3个部分以最少的耦合协同工作，从而提高了应用的可扩展性和可维护性。它使用了目前最为流行的Java语言，结合JSP技术，在MyEclipse集成开发环境下编写，用户界面友好。其中B/S结构得以让数据在IE浏览器上显示，数据处理在服务器上进行，用户不必安装客户端，而且数据通过服务器端的统一管理，保证其一致性。另外系统使用小型关系型数据库MySQL作为网站的后台数据库系统。本系统总体可分成两大基本功能：前台管理和后台管理。前台管理主要包括用户注册、登录、注销、密码找回、修改用户信息、浏览图书、订购图书、提交订单、查看特价图书信息等功能。后台管理主要包括登录、图书维护、订单处理、确认订单、发送订单等功能。通过对各个模块的实现、集成，最后完成的系统可以为用户提供基本的服务，并且可以根据管理员的需要，对用户的信息以及图书信息实施管理。【关键词】网上书店；Java；MyEclipse；JavaEE；B/S；MySQL；MVC2AbstractWiththedevelopmentofthenetwork,basedoncomputerinformationmanagementefficiency,allkindsofinformationmanagementplatformintopeople'shorizons.Amongthem,theonlinebookstoreisatypicalapplicationofmanaginginformationsystem(MIS).ThissystemisbasedonJavaEEthree-layerstructureofB/S(Browser/Server)modelsoftware,includethefollowingthreeparts:thepresentationlayer,businesslogiclayeranddataaccesslayer.CombiningwiththeMVCframeworkModelofhierarchicalstructure,willbeappliedintotheModel,theView,theControlthreeparts.Threepartstoworktogetherwiththeleastamountofcoupling,soastoimprovethescalabilityandmaintainabilityoftheapplication.ItUSESatpresentthemostpopularJavalanguage,combinedwithJSPtechnology,writeinMyEclipseintegrationdevelopmentenvironment,userfriendlyinterface.WithB/SstructuretomakedataonInternetexplorer,accordingtothedataprocessingontheserver,theuserdoesnothavetoinstalltheclient,andthedatathroughaserver-sideunifiedmanagement,ensuretheconsistency.ThesystemusingasmallrelationaldatabaseMySQLasthewebsitebackstagedatabasesystem.Thissystemingeneralcanbedividedintotwobasicfunctions:thefrontdeskandbackgroundmanagement.Frontdeskmanagementmainlyincludestheuserregister,login,logout,password,retrieve,modifyuserinformation,browsethebooks,orderbooks,submitorders,viewthespecialbookinformation,andotherfunctions.Backgroundmanagementmainlyincludesthelogin,bookmaintenance,orderprocessing,confirmationoforderandsendtheorder,andotherfunctions.Throughtheimplementationofeachmodule,integration,andfinallycompletedsystemcanprovidebasicservicesforusers,andcanaccordingtotheneedsoftheadministrator,theuserinformationandbookinformationmanagement.【Keywords】OnlineBookstore,Java,MyEclipse,JavaEE,B/S,MySQL,MVC3目录第1章绪论.....................................................................................................................................11.1论题提出的背景和意义...............................................................................................11.2国内外现状的研究.......................................................................................................21.3研究内容.......................................................................................................................3第2章系统研究的相关知识.........................................................................................................42.1JavaEE简介..................................................................................................................42.1.1什么是JavaEE..................................................................................................42.1.2JavaEE常用技术..............................................................................................52.1.3分层架构模式...................................................................................................62.2MVC框架技术Struts2................................................................................................72.3JavaScript脚本语言.....................................................................................................72.4MySQL简介.................................................................................................................82.5B/S体系结构................................................................................................................92.6MyEclipse和Tomcat7.0的简要介绍........................................................................10第3章项目的系统分析...............................................................................................................113.1可行性分析.................................................................................................................113.2需求分析.....................................................................................................................133.3用例分析.....................................................................................................................133.4数据流图.....................................................................................................................153.5实体关系图.................................................................................................................16第4章项目的系统设计...............................................................................................................174.1功能设计.....................................................................................................................174.2数据库设计.................................................
