本文详细介绍了如何使用Openfire作为即时通讯服务端的搭建过程，包括数据库配置、服务端启动及配置，并展示了如何使用Spark客户端进行用户注册与登录。

现决定使用Openfire作为服务端，Openfire采用Java开发，基于XMPP的实时开源协作服务器。单台可支持上万并发用户。

Openfire体系结构

Openfire体系由其提供的服务器端、客户端以及相应的开发库组成。

Openfire

通常我们所说的Openfire就是指Openfire服务端，现在已经更新到3.10.3版本，该服务器实现了绝大部分的XMPP协议。

除此之外，还有大量的Openfire插件可供使用。

Spark

Spark是一个使用java开发的实时协作客户端，通过简单的配置和注册即可使用。

Smack

Smack is a client library. You can use it to log into an XMPP domain and make use of the functionality it provides. Typically, Smack is used to implement an instant messaging client。

Tinder

Tinder is a low-level XMPP library. It provides Java implementations of basic XMPP entities, such as Stanzas (called 'Packet' in XMPP), JIDs and Components (which typically implement part of the functionality of an XMPP server). Although in theory, Tinder could be used to implement client functionality, it currently is primarily used on the server-side. Both Whack and Openfire (an XMPP server implementation) use Tinder-defined entities. Smack does not use Tinder at all.

Whack

Whack is Java library that is used to implement external components. Whack allows a Component (as defined in Tinder) to run as a stand-alone process. Whack allows you to connect this process to an XMPP domain. This way, you can extend the functionality provided by that domain without modifying the implementation of the server software.
