Introduction
RabbitMQ是一个消息代理:它接受并转发消息.你可以把它当成一个邮局:当你想邮寄信件的时候,你会把信件放在投递箱中,并确信邮递员最终会将信件送到收件人的手里.在这个例子中,RabbitMQ就相当与投递箱,邮局和邮递员.
AMQP协议中的核心思想就是生产者和消费者隔离,生产者从不直接将消息发送给队列.生产者通常不知道是否一个消息会被发送到队列中,只是将消息发送到一个交换机.先由Exchange来接收,然后Exchange按照特定的策略转发到Queue进行存储.同理,消费者也是如此.Exchange 就类似于一个交换机,转发各个消息分发到相应的队列中.
RabbitMQ Work Mode
Direct – 路由模式
直连型交换机，根据消息携带的路由键将消息投递给对应队列
大致流程,有一个队列绑定到一个直连交换机上,同时赋予一个路由键 routing key.
然后当一个消息携带着路由值为X,这个消息通过生产者发送给交换机时,交换机就会根据这个路由值X去寻找绑定值也是X的队列.

扇型交换机,这个交换机没有路由键概念,就算你绑了路由键也是无视的. 这个交换机在接收到消息后,会直接转发到绑定到它上面的所有队列.

Topic – 匹配订阅模式
主题交换机,这个交换机其实跟直连交换机流程差不多,但是它的特点就是在它的路由键和绑定键之间是有规则的.
简单地介绍下规则:
- (星号) 用来表示一个单词 (必须出现的)
(#) 用来表示任意数量（零个或多个）单词
通配的绑定键是跟队列进行绑定的,举个小例子
队列Q1 绑定键为 .TT. 队列Q2绑定键为 TT.#
如果一条消息携带的路由键为 A.TT.B，那么队列Q1将会收到;
如果一条消息携带的路由键为TT.AA.BB，那么队列Q2将会收到;
