消息代理作为企业应用集成中的核心组件，承担着消息验证、转换及路由的重要职责。它使得应用程序无需直接了解其他应用的存在即可进行交互，从而实现非侵入式的集成方式。

The notion of a Message Router is central to the concept of a Message Broker, implemented in virtually all commercial EAI tools. These tools accept incoming messages, validate them, transform them, and route them to the correct destination. This architecture alleviates the participating applications from having to be aware of other applications altogether because the Message Broker brokers between the applications. This is a key function in enterprise integration because most applications to be connected are packaged or legacy applications and the integration has to happen nonintrusively—that is, without changing the application code. Therefore, the middleware has to incorporate all routing logic so the applications do not have to. The Message Broker is the integration equivalent of a Mediator presented in [GoF].
