摘要I摘要近年来随着计算机的日益普及和网络（特别是因特网）的迅速发展，在全球范围内形成了一种新的企业经营方式,他们把所有的商业活动和贸易往来电子化,利用发达的网络环境进行快速有效的商业活动。这就是最近成为世界上最热门的话题：电子商务。凡是利用国际互联网进行商务活动的一种方式就是电子商务。电子商务以其高效率、低廉、高收益、全球化等传统经营方式所无法比拟的优点受到全球的关注。其中通过网上书店，人们可以足不出户就选购自己所需的图书。网上书店是根据公司的实际需求、应用动态网页技术开发而成。该系统主要是对图书商品进行的一系列操作；并具有占用系统资源少、信息量大的特点，并且可以克服传统图书销售中地域、广告宣传、人力资源不足等限制，能很好地适应网上销售需求。本设计中主要功能模块包括：交易系统采用4层结构，主要包括：表现层、控制层、业务层、持久层。表现层：主要是负责用户交互和结果显示。控制层：主要是负责系统的访问控制、数据加载和注销，它是系统的核心控制单元。控制层通过系统的描述来组织工作。业务层：实现了交易系统的主要业务逻辑，是系统的主要运算单元。持久层：实现静态数据和数据库数据的持久化管理，为业务层提供数据服务，是系统进行数据操作的统一界面。设计中使用的主要开发技术有Html，Javascript，JavaSE，JSP，Servlet，JDBC，MVC，Struts。使用的数据库技术是Mysql。本文介绍了网上书店系统的开发模式和环境，并具体阐述了系统分析、总体设计、系统设计系统的实现及性能测试与分析等过程。关键词：网上书店；MySql数据库；JAVA；Struts技术；JDBC技术AbstractIIAbstractInrecentyears,withthepopularizationofcomputerandnetwork(especiallyontheInternet)therapiddevelopment,theformationofanewmodeofenterprisemanagementintheglobalscope,theyputallofthecommercialactivitiesandtradeelectronic,fastandeffectivebusinessactivitiesbyusingadvancednetworkenvironment.Thisistherecentlybecamethehottopicintheworld:electroniccommerce.UsuallyawaytocarryoutbusinessactivitiesbyusingtheInternetistheelectroniccommerce.Theadvantagesofelectroniccommercewithitshighefficiency,low,highyield,globalization,thetraditionalmanagementofunmatchedglobalattention.Theonlinebookstore,peoplecanremainwithindoorswillchoosethebooks.Onlinebookstoreisbasedontheactualdemand,dynamicwebpagetechnologydevelopmentandapplication.Thesystemismainlyaseriesofoperationofcommodity;andhastheadvantagesofoccupyinglesssystemresources,alargeamountofinformation,anditcanovercomethetraditionalbooksalesintheregion,advertising,humanresourceslackofrestrictions,canbewelladaptedtotheneedsofonlinesales.Themainfunctionmodulesofthedesigninclude:tradingsystembyusing4layerstructure,mainlyincluding:thepresentationlayer,controllayer,businesslayer,persistencelayer.Presentationlayer:mainlyresponsibleforuserinteractionandresultdisplay.Themainaccesscontrollayer:responsibleforsystemcontrol,dataloadingandcancellation,isthecoreofthesystemcontrolunit.Controllayertoorganizeworkthroughthesystemdescription.Businesslayer:toachievethemainbusinesslogictransactionsystemandmanagementsystem,isthemainoperationalunitsystem.Thepersistencelayer:realizingthepersistencemanagerstaticdataanddatabasedata,providingdataservicesforthebusinesslayer,isaunifieddatainterfaceoftheoperatingsystem.ThemaindevelopmenttechnologyusedinthedesignofHtml,Javascript,JavaSE,JSP,Servlet,JDBC,MVC,Struts.UsingthedatabaseisMysql.Thispaperintroducesthedevelopmentofonlinebookstoresystemmodelandenvironment,andspecificallyonthesystemanalysis,systemdesign,systemdesign,systemimplementationandperformancetestingandanalysisprocess.Key:onlinebookstore；MySqlDatabase；JAVA；StrutsTechnology；JDBCTechnology目录III目录摘要………………………………………………………………………………………….IAbstract…………………………………………………………………………………..II第1章绪论………………………………………………………………………………1第2章系统分析………………………………………………………………………….22.1需求分析..............................................................................................................22.2可行性分析.............................................................................................................2第3章总体设计………………………………………………………………………….33.1项目规划..............................................................................................................33.2访问控制流程图.................................................................................................33.3功能结构..............................................................................................................43.4用例描述..............................................................................................................5第4章系统设计…………………………………………………………………………134.1设计目标..................................................................................................................134.2开发及运行环境.....................................................................................................134.3系统概要设计.........................................................................................................134.4数据库设计.............................................................................................................14第5章系统的实现………………………………………………………………………175.1登录的实现.............................................................................................................175.2会员注册界面.........................................................................................................185.3菜单显示功能的实现.............................................................................................195.4商品浏览功能的实现.............................................................................................215.5热销图书等功能的实现........................................................................................215.6购物车功能的实现.................................................................................................215.7订单的实现.............................................................................................................24第6章性能测试与分析…………………………………………………………………
