Smack是作为开源可扩展消息传递和存在协议客户端库开发的，旨在帮助用户将 XMPP 功能嵌入到他们自己的应用程序中。通过其广泛的库和可选的 XEP 扩展，该应用程序将允许人们将其实施到他们的实用程序中并设计完整的 XMPP 客户端包或基本消息传递协议。
Smack协议客户端库开发应用程序通过与 XMPP 服务器实时通信来工作，以实现即时消息和群聊连接。使用提供的编程接口，可以通过编写相应的代码行来发送文本消息。
使用Java编程语言构建，它的库可以很容易地嵌入到与 Java 兼容的应用程序中。应用程序将其库部署为单独的 JAR 文件，旨在为应用程序所需的功能提供增强的控制和灵活性。
Smack协议客户端库开发为了启用该应用程序，必须运行一个两步初始化过程。第一个意味着初始化系统属性，这些属性可以通过 SmackConfiguration 类访问。第二个将调用并启用所有需要在启动时处于活动状态的类，使用 SmackInitializer 类。
通过运行相应的命令行来控制不同的工具，库的 JAR 文件提供核心 XMPP 功能、XMPPTCP 连接、多用户聊天、文件传输、用户搜索等。支持由 XMPP 标准基金会定义的遗留扩展提供，并且还提供了 BOSH (XEP-0124) 代码。
Smack协议客户端库开发系统要求
JAVA JRE
Smack was developed as an open source extensible messaging and presence protocol client library to help users embed XMPP functionality into their own applications. With its extensive library and optional xep extensions, the application will allow people to implement it into their utilities and design a complete XMPP client package or basic messaging protocol.
Smack protocol client library development application works through real-time communication with XMPP server to realize instant messaging and group chat connection. Using the provided programming interface, you can send text messages by writing corresponding lines of code.
Built using the Java programming language, its library can be easily embedded in Java compatible applications. The application deploys its library as a separate jar file to provide enhanced control and flexibility for the functions required by the application.
Smack protocol client library development in order to enable the application, a two-step initialization process must be run. The first means initializing system properties, which can be accessed through the smackconfiguration class. The second will call and enable all classes that need to be active at startup, using the smackinitializer class.
