    Exchanges概念 RabbitMQ消息传递模型的核心思想是: 生产者生产的消息从不会直接发送到队列。实际上,通常生产者甚至都不知道这些消息传递传递到了哪些队列中。 Exchanges的类型 总共有以下类型: 直接(direct), 主题(topic) ,标题(headers) , 扇出(fanout) 无名exchange 前面部分我们对exchange一无所知,

    survive broker restart whereas transient exchanges do not (they have to be redeclared when broker comes Headers exchanges ignore the routing key attribute. Headers exchanges can be looked upon as "direct exchanges on steroids". Because they route based on header values, they can be used as direct exchanges where the routing key Bindings are rules that exchanges use (among other things) to route messages to queues.

    Listing exchanges 对于列出服务器上的exchanges , 你可以使用rabbitmqctl sudo rabbitmqctl list_exchanges The default exchange 在前面的教程中,我们不知道exchanges,但是我们仍然可以发送messages 到queues. 这种fanout exchanges ,在发送时,会忽视routingKey的值。

    交换器(Exchanges) 在前面的教程部分中,我们发送、接收消息都是来自一个队列中的。现在是时候介绍一下RabbitMQ中完整的消息模型了。 并指定名称为logs,类型为广播型(fanout) channel.exchangeDeclare("logs", "fanout"); 列出交换器 你可以通过 rabbitmqctl list_exchanges 命令查看交换器列表: $ sudo rabbitmqctl list_exchanges Listing exchanges ... 在这个结果集列表中有一些 amq.*.exchanges 和默认未命名的交换器。这些都是RabbitMQ默认创建的,但是你未必能用到它们。
