编程实验
即时通讯(Instant Messaging)是目前Internet上最为流行的通讯方式,各种各样的即时通讯软件也层出不穷;服务提供商也提供了越来越丰富的通讯服务功能。不容置疑,Internet已经成为真正的信息高速公路。从实际工程应用角度出发,以计算机网络原理为指导,结合当前网络中的一些常用技术,编程实现基于C/S架构的网络聊天工具是切实可行的。
目前,中国市场上的企业级即时通信工具主要包括:信鸽、视高科技的视高可视协同办公平台、263EM、群英CC2010、通软联合的GoCom、腾讯公司的RTX、IBM的Lotus Sametime、点击科技的GKE、中国互联网办公室的imo、中国移动的企业飞信、华夏易联的e-Link、擎旗的UcStar等。相对于个人即时通信工具而言,企业级即时通信工具更加强调安全性、实用性、稳定性和扩展性。
本文为大家介绍java Smack整合Openfire服务器实现IM即时通讯聊天功能代码。
