}前言自我国正式进入互联网时代以来，短短的几年时光互联网在我国得到了飞速的发展。目前它已经成为全球性信息传输的重要途径之一，并被喻为信息高速公路。这不仅表现在互联网的基础设施方面，也表现在互联网的用户人数、互联网在各行各业的广泛应用等各个方面。现实生活中的交流存在时间和空间上的局限性，交流人群范围狭小以及间断的交流不能保证信息的准确性和可取性。因此伴随着网络的普及，论坛逐渐融入人们的生活。人们只需通过网上论坛的交流扩大交流面，同时可以从多方面获得自己所需要的最及时的信息。快速及时的进行交流现已成为人们生活中的一部分。五彩缤纷的网上信息，使网络与人们的生活息息相关，于是出现了专题论坛。它打破了地域限制，真正使信息得以全部共享，改变了人们的工作和生活方式。专题论坛是区域内个人和个人的宣传自己的重要手段，同时人们了解当代社会的一种现状，也是了解信息的重要手段。专题论坛系统是基于B/S模式上的一种交互性极强的电子信息服务系统。它为网民提供一块公共的交流平台，每个用户都可以在上面发布自己的观点和不同的意见，以便与其他用户进行交流和讨论。第1章 专题论坛系统开发背景及意义1.1 系统开发背景论坛又名网络论坛BBS，全称为Bulletin Board System（电子公告板）或者Bulletin Board Service（公告板服务）。是Internet上的一种电子信息服务系统。它提供一块公共电子白板，每个用户都可以在上面书写，可发布信息或提出看法。它是一种交互性强，内容丰富而即使的Internet电子信息服务系统。用户在专题论坛上可以获得各种信息服务，发布信息，进行讨论，聊天等等。论坛的发展也如同网络，雨后春笋般的出现，并迅速的发展壮大。现在的论坛几乎涵盖了我们生活的各个方面，几乎每一个人都可以找到自己感兴趣或者需要了解的专题性论坛，而各类网站，综合性门户网站或者功能性专题网站也都青睐于开设自己的论坛，以促进网友之间的交流，增加互动性和丰富网站的内容。 而专题论坛只是其中的一类。.rtcscls-3-p_0 { }.rtcscls-3-p_1 { line-height: 183.33333333333%;

}此类论坛是相对于综合类论坛而言，专题类的论坛，能够吸引真正志同道合的人一起来交流探讨，有利于信息的分类整合和搜集，专题性论坛对学术科研教学都起到重要的作用，例如军事类论坛，情感倾诉类论坛，电脑爱好者论坛，动漫论坛，这样的专题性论坛能够在单独的一个领域里进行版块的划分设置。在本文中，主要介绍使用JSP和Servlet技术来实现论坛建设。通过基于Internet互联网的动态WEB数据库技术，可以解决远程的数据传输与读取，远程的客户终端（Client）可以通过WEB页面提交请求，查询远端的数据服务器上的信息，同时还可以向远端数据服务器的数据库中存储信息,以实现信息的共享，同时利用Internet技术可以降低软件的开发和部署成本，只要在服务器端安装WEB应用就可以使每个客户端都能浏览使用。目前，通过专题论坛系统可随时取得各种自己需要最新的信息；也可以通过专题论坛系统来和别人讨论计算机软件、硬件、Internet、多媒体、程序设计以及人文、地理等等各种有趣的话题；还可以利用本系统来发布一些“问题”、“廉价转让”、“招聘人才”及“求职应聘”等启事；更可以召集亲朋好友到聊天室 内高谈阔论……这个精彩的天地就在你我的身旁，只要您拥有一台可以访问互联网的计算机，就可以通过这个交流平台，来享用它的种种服务。1.2 系统开发意义当今网络技术逐渐渗入社会生活各个层面，以前网站上的专题论坛管理系统要用户登陆以后才能进行相关访问及互动。而随着网络互联技术的进步，现在网站投票只需打开网页就可进行论坛留言。专题论坛对象是很多的，各个层次都可进行论坛访问，大至国家领导，小至一个普通干部，访问和留言从到指定用户进行表格到现在通过网络直接点击相应就可进行。专题论坛管理系统可解决游客访问及留言，致使现在几乎各个网站都有各种类型的专题论坛管理系统，用户可选择自己的看法。同时为分散于五湖四海的人们提供一个共同交流、学习、倾吐心声的平台，实现来自不同地方的用户极强的信息互动性，用户在获得自己所需要的信息的同时也可以广交朋友，拓宽自己的视野和社交面。.rtcscls-4-p_0 { text-align: left;

}通过网友的发帖中，能得到有益的教诲和启发。网友通过发出关于国家，社会的有益的观点，能被有关部门采纳，而不是网友空自评论，自艾自叹，自喜自悲。一些论点能做到各方观点正确公平的显示，具有参考价值。专题论坛应具有知识性，趣味性，公平性，和谐性等优点。专题论坛给天下的网民都提供了交流的平台，为网络的互动性作出了巨大的贡献，通过专题论坛，网民们得以更方便的交流，更便捷的发表自己的观点，而且发布信息都是通过有记录的文字来进行，所以这样也避免了精华内容的流失。通过专题论坛来征得自己想要的信息，有更高的效率和时效性。也最节约成本和资源，在专题论坛的交流过程中，无论喜怒哀乐都是在虚拟的环境中进行，也避免的正面的尴尬和冲突等，在专题论坛中，可以演变成任何角色，变换多种身份，因为网络的特征，使得人民更加依赖于论坛中的交流。第2章 专题论坛系统需求分析2.1现状分析随着全球英特网用户逐年增多,在中国，据中国互联网信息中心（CNNIC）最新的调查报告显示，截止2003年6月底，上网用户已达到6800万，比去年同期增长48.5％，而1997年10月首次调查结果只有62万，几年间增长了109.7倍。上面数据可以看出当今社会网络迅速普及，人们交流的方式也层出不穷，随着新时代的进入。人们对信息的需求也不断加大，对不同领域的讨论也越来越多了，因此开发一个专题论坛对人们的交流是非常有必要的。2.2可行性分析可行性分析也称为可行性研究，即是在系统调查的基础上，针对新系统的开发是否具备必要性和可能性，对新系统的开发从技术、经济、管理的方面进行分析和研究，以避免投资失误，保证新系统的开发成功。可行性研究的目的就是用最小的代价在尽可能短的时间内确定问题是否能够解决。该系统的可行性分析包括以下几个方面的内容。2.2.1经济可行性主要是对项目的经济效益进行评价，利用计算机来实现网上交流信息。开发一套能满足网上信息交流的软件是十分必要的，实现用户发帖，回帖等功能，能发表自己的观点。本系统在经济上是完全可以接受的，只需要用户在本地安装Web浏览器，登录论坛就可以浏览帖子并发表自己的意见。所以本系统在经济上是可行的。.rtcscls-5-p_0 { }.rtcscls-5-p_1 { }.rtcscls-5-p_3 { text-align: center;
