摘要随着计算机网络技术的快速发展，人们的交流方式越来越多，传统的通信方式在速度和可靠性方面已经很难满足人们的需要，即时通信系统已经越来越受欢迎。同时，即时通信系统对现代企业也有着重大意义，它为诸企业开拓了网络应用的新领域。自从它诞生以来，以实时交互、资费低廉等优点，受到广大个人用户的喜爱，已经成为网络生活中不可或缺的一部分。本着学以致用的原则，本人开发了这套多用户网络聊天室系统，以满足网络用户的通讯需求。该系统具有操作简单、界面友好、功能丰富等优点。它采用Eclipse为基本开发环境，用java语言进行编写，开发中充分使用了计算机网络编程的基本理论知识，如TCP/IP协议、客户端/服务器端模式（Client/Server模式）、网络编程、JDBC数据库编程技术等。本论文就系统的开发过程做了详细的介绍，并对系统的原理、总体设计等方面做了深入细致的讨论。关键词:聊天室SocketJavaJDBC网络编程AbstractAlongwiththerapiddevelopmentofcomputernetworktechnology,thewaysofpeople’scommunicationareincreasedrapidly.Thetraditionalmeansofcommunicationhasbecomeverydifficulttomeetpeople'sneedsinspeedandreliability.Instantcommunicationsystemhasbecomethenewdarlingsofthepeople.Meanwhile,Instantcommunicationsystemisalsoofgreatimportancetothemodernenterprises.Itexploitsanewdomainfortheenterprise.Ithasbeenenjoyedbythemajorityofindividualusersforitsreal-timeinteractionbetweentheadvantagesoflowratessinceitsbored.Ithasbeenanintegralpartofnetworklife.Inapplyoftheprincipleofpractice,Idevelopedthesetofmulti-pointchattingsystemtomeetthenetworkusers'needsofcommunication.Thissystemhassomecharacteristicasfollows:simplifyoperation,friendlyinterface,singlefunction.ThebasicdevelopmentenvironmentwithEclipse,writtenwithjavalanguage,developmentofcomputernetworkprogrammingusingthebasictheoryofknowledge,suchasTCP/IPprotocol,client/servermode(Client/Servermode),networkprogrammingdesignmethod.Thispaperintroducedtheprocessofthesystem'sdevelopmentindetail,anddeeplydiscussedtheprincipleofsystem、collectivitydesign.Keywords:ChattingroomSocketJavaJDBCNetworkprogramming目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc309915744"1.前言PAGEREF_Toc309915744\h6HYPERLINK\l"_Toc309915745"1.1开发背景和意义PAGEREF_Toc309915745\h6HYPERLINK\l"_Toc309915746"1.2可行性分析PAGEREF_Toc309915746\h6HYPERLINK\l"_Toc309915747"1.2.1技术可行性PAGEREF_Toc309915747\h6HYPERLINK\l"_Toc309915748"1.2.2经济可行性PAGEREF_Toc309915748\h8HYPERLINK\l"_Toc309915749"1.2.3操作可行性PAGEREF_Toc309915749\h8HYPERLIN
