基于Servlet的网上报名系统的设计与实现近年来,尤其是随着信息化的迅速传播,各类网上报名接踵而至,网上报名的当务之急就是引入现代化的信息技术,这既是机遇也是挑战。本文主要研究背景是某外语考试的网上报名系统项目。所构设的网上报名系统是集考务管理为一体的网上报名系统,其除了包括网上信息采集、数据库操作安排准考证外,还有考试管理、数据下载上传、下载准考证等,它在考生与教育部门之间搭建了一座相互交流的平台。该设计系统主张采用JSP/JavaServlet技术和B/S模式,利用JavaJDBC与数据库连接,使用连接池提升Servlet访问数据库的效率。本文对该系统的市场分析、设计原则、系统开发模式和系统运行平台进行了阐述,且对系统数据库结构和访问原理进行了详规介绍,同时,详细地描述了各功能模块的结构和实现过程,其中除了有系统考生网上报名模块、考生模块、现场报名点管理模块外,还有系统登陆模块、主管部门管理模块以及系统管理员模块等。与此同时,本文除了对系统的用户认证技能、用户角色及数据库安全策略进行阐释外,还详实的阐释了数据库连接池、系统开发与运行中的一些错误的预防与处理机制等。除此之外,给出了一种全新的映射随机算法,既缩减了系统运行时间又提高了其运行效率。采用这些技术和方法,除了能有效地提高系统的安全性外,还能提高系统的并发性,以满足大量用户的需求。关键词:网上报名;随机算法;数据库连接AbstractSincetheeducationreform,especiallywiththerapidspreadofinformationtechnologyineducation,reformofthevarioustypesofexaminationsfollowed,teachingmanagementinpriorityistheintroductionofmoderneducationaltechnology,whichisbothanopportunityandachallenge.Thispaperstudiesthebackgroundofforeignlanguageexaminationstheonlineregistrationsystemproject.Theinstitutionssetuponlineregistrationsystemisasetoftestmanagementasoneoftheonlineregistrationsystem,Inadditiontoincludingtheonlineinformationcollection,databaseoperations,arrangingticketoutside,aswellasexaminationmanagement,datadownload,upload,downloadticket,itbuiltaplatformofmutualexchangebetweenthecandidateswiththeeducationsector.ThedesignadvocatetheuseofJSP/JavaServletandB/Smode,touseJavaJDBCforthedatabaseconnectionandusingtheconnectionpooltoenhancetheefficiencyoftheServlettoaccessthedatabase.Tothesystemmakethemarketanalysis,describethedesignprinciples,systemdevelopmentmodelandoperatingsystemplatform,andthedatabasestructureandaccesstotheprincipleoftheintroductionofdetailedregulations,atthesametime,introduceadetaileddescriptionofthestructureofeachfunctionalmoduleandtheimplementationprocess,inadditionintroducetheonlineregistrationmoduleofthesystem,candidates,candidatemodule,on-siteregistrationpointmanagementmodule,thesystemloginmodule,thedepartmentinchargeofthemanagementmoduleandthesystemadministratormodule,etc.Atthesametime,inaddition,discribetheskillsoftheuserauthenticationsystem,userroles,anddatabasesecuritypoliciestointerpretation,butalsodetailedexplanationofthedatabaseconnectionpool,someerrorsinthesystemdevelopmentandoperationofthepreventionandhandlingmechanism.Otherwise,giventhemappingofanewrandomizedalgorithms,bothtoreducethesystemoperationtimeandimproveitsoperatingefficiency.Usingthesetechniquesandmethodsofadditioncaneffectivelyimprovethesecurityofthesystem,butalsoimprovetheconcurrencyofthesystemtomeettheneedsofthelargenumberofusers.Keywords:Onlineregistration,Randomizedalgorithms,Databaseconnectionpool目录1绪论1.1网上报名系统的研究背景......................................11.2网上报名系统的重要性及意义....................................................................11.3国内外考...
