消息中间件(Message—OrientedMiddleware，简称MOM)提供客户和服务器的同步和异步连接，并且在任意的时刻对消息进行传送和存储转发。消息的传输一般都支持Point—to—Point模式和Publish／Subscribe模式。消息中间件为大规模分布式环境下应用程序的集成提供了一种有力的集成工具。越来越多的分布式应用采用消息中间件，通过消息中间件把应用扩展到不同的操作系统和不同的网络环境。-Message-Oriented Middleware (Message-OrientedMiddleware, referred to as MOM) to provide clients and servers to connect synchronous and asynchronous, and at any time of messages send and store-and-forward. Message transmission is generally in support of Point-to-Point mode and Publish/Subscribe model. Message-Oriented Middleware for large-scale distributed environment application integration provides a powerful integration tools. A growing number of distributed applications using Message-Oriented Middleware, Message Oriented Middleware, through the application be extended to different operating systems and different network environments.
