一，名词介绍
Server:又称 Broker,接受客户端的连接,实现AMQP实体服务。Connection:连接,应用程序与 Broker的网络连接。Channel:网络信道,几乎所有的操作都在 Channel中进行, Channel是进行消息读写的通道。客户端可建立多个 hannel,每个 Channel代表一个会话任务。Message:消息,服务器和应用程序之间传送的数据,由 Properties和Body组成。 Properties可以对消息进行修饰,比如消息的优先级、延迟等高级特性;Body则就是消息体内容。Virtual host:虚拟地址,用于进行逻辑隔离,最上层的消息路由。个 /irtual Host里面可以有若千个 Exchange和 Queue,同一个 VirtualHost里面不能有相同名称的 Exchange或 Queue。Exchange:交换机,接收消息,根据路由键转发消息到绑定的队列。Binding: Exchange和 Queue?之间的虚拟连接, binding中可以包含 routing keyRouting key:一个路由规则,虚拟机可用它来确定如何路由一个特定消息Queue:也称为 Message Queue,消息队列,保存消息并将它们转发给消费二，hello world，简单队列
