基于J2EE的大型视频影音系统的设计与实现
摘 要
在众多的Web2.0应用和服务中，视频分享脱颖而出成为最新的爆发点。视频分享网站为用户提供视频上传、播放和分享服务，操作简单，传播方便，加上视频本身能带来丰富的用户体验，视频分享网站受到广泛欢迎。我们对系统体系结构进行分析，对C/S、B/S两种结构进行了比较，根据系统目标的设计需求，从适用性、移植性等因素出发，选用B/S作为本系统的开发平台，服务器采用tomcat 6.0，数据库采用MySQL，使用Jsp开发。
本文讨论了数据库创建；数据的增加、删除、修改、查询；数据的统计、归类等问题。在系统中设计了网络通信功能，为用户观看视频、视频留言，管理员管理视频留言提供了保障；系统还设计了文件上传、下载功能，为用户上传视频、上传头像提供了方便；系统为用户设计了相关查询，用户可以查询自己感兴趣的视频。
对于视频分享网站来说，与网民规模的持续增长相比，宽带用户的增长具有更加重要的意义，因为宽带上网显然更加利于用户在线欣赏视频内容。宽带用户数量的增长速度高于同期网民数量的增长速度，因此网民中宽带用户比例不断增加，最新的统计数据显示这个比例已经超过75%。宽带日益普及对于视频分享网站的发展无疑具有至关重要的意义。
在2005年及之前，中国视频分享市场处于初始期，网站数量少、用户规模小、访问量低，视频分享服务尚未获得网民的广泛了解和接受，网站影响范围有限，商业模式模糊不清。
进入2006年后，视频分享市场进入成长期。这一阶段经过前一时期的营销宣传、服务提升和用户积累，视频分享网站开始快速发展。尤其是千万美元级风险投资先后注入主要的视频分享网站，整个视频分享网站市场获得的极大的推动，开始爆发式增长，无论是网站数量，还是用户规模都急剧增加。而YouTube被Google以16.5亿美元天价收购的事件，则将视频分享网站快速发展的热潮推升至前所未有的高度。

Large Video Audio System Based on J2EE Design And Implementation
Abstract
In many applications and services, Web2.0 video sharing emerged as the latest outbreak. Video sharing website to provide users with video broadcast and upload, sharing service, simple operation, convenient communication, add video itself can bring rich user experience, video sharing website is widely welcomed. We analyzed the structure of system of C/S and B/S structure of two kinds of comparison, according to the demand of the target system design, from the applicability, such as selection of B/S as this system developing platform, server, database by using MySQL tomcat 6.0, use the Jsp development.
Create a database is discussed in this paper, Data of add, delete, modify, query, Data statistic and classification problems. In system design, network communication function for users to watch video, the video message video message administrator management, provides the security, System design for file upload, download for users to upload video functions, provides the convenience, upload head, System was designed for the user, users can query relevant interested in video.
For video sharing website, and sustained growth of the Internet, the scale of the growth of broadband users compared with the more important, because the broadband users online appreciate more clearly for video content. The number of broadband users is growing even faster than the same number of Internet users in the growth of broadband users, thus increasing ratio, the latest statistics show that more than 75 percent rate. Increasingly popular video sharing broadband for website development has vital significance.
In 2005, China's video sharing before and at the initial stage, the market web quantity, small size, low traffic users, video sharing service of Internet users has won extensive understanding and accepting, website, commercial mode, affect blurred.
From 2006, video sharing entering into the market growth. This stage before after a period of marketing and service enhancement and users, video sharing website begin accumulating rapidly. Especially the million dollar level of risk investment has injected video sharing website, mainly the video sharing website of the market, and began to BaoFaShi growth, or the number of web users are increased dramatically. But by Google on YouTube 16.5 billion takeover of the day, will share the rapid development of web video push to unprecedented upsurge of height.
