This mode is more complex, simply put, is that each queue has its own topic of interest, all messages with a "title" (Routekey), Exchange will forward the message to all the topics of interest can match the Routekey fuzzy queue.2. This mode requires Routekey, perhaps to bind exchange and queue in advance.3. When binding, to provide a topic that the queue cares about,

本章我们重点学习一下Rabbit里面的exchange（交换器）的知识。交换器分类RabbitMQ的Exchange（交换器）分为四类：Direct (default)HeadersFanoutTopicThe headers switch allows you to match the header of the AMQP message instead of the routing key, in addition to the headers switch and the direct switch is exactly the same, but the performance is very poor, almost useless, so we do not explain this article.注意：f

From: http://melin.iteye.com/blog/691265RabbitMQ three types of exchange Blog type: Amqp Exchangeredhat job Direct Exchange-Process the route key. To bind a queue to a vswitch, the message must match a specific route key. This is a complete match. If a queue is bound to a vswitch and the routing key "dog" is required, only messages marked as "dog" are forwarded and dog messages are not forwarded. puppy

Fanout MulticastIn the previous use of direct direct-connect switches, the Routingkey was used to decide which queue to push messages to. Fanout, in turn, pushes the received message into all the queues it binds to. Analysis of the business, what scenarios need it? A user registered the site of the user, generally we need to send text messages and e-mail notification, is it necessary to in the same consumer to do both of these things? This is not a single responsibility, but the message sent is
