|
||||||
|
* 简单说明:
|
||||||
|
* 1、之前工作模型中,我们虽然由多个消费者但是每个消息只能被一个消费者消费;在发布订阅模型中只要订阅了这个消息的消费者都可以接收到消息
|
||||||
|
* 2、正规的 RabbitMQ 使用方式,消息生产者先将消息发送到 Exchange 交换机中,在根据一定的策略将消息投递到队列中,消息生产者甚至不用知道队列的存在
|
||||||
|
* 3、Exchange 交换机需要做两件事:第一、接收来自生产者发送的消息;第二、将消息投递到队列中
|
||||||
|
* 4、Exchange 交换机必须知道如何正确的将消息投递到队列中(Direct exchange、Fanout exchange、Topic exchange、Headers exchange)

|
||||||
|
* RabbitMQ 工作队列模型,是创建多个消费者共同消费消息,每个消息只可以被一个消费者处理
|
||||||
|
* 默认是轮询策略
|
||||||
|
*
|
||||||
|
* 简单队列模型和工作队列模型对比:
|
||||||
|
* 区别:
|
||||||
|
* 1、简单队列模型:是一个消费者和一个生产者
|
||||||
|
* 2、工作队列模型:由一个生产者生产消息,多个消费者共同消费消息,但是每个消息只可以被一个消费者处理
|
||||||
|
*
|
||||||
|
* 共同点:两种队列模型:都是直接将消息发送到Queue队列中,并没有Exchange交换机参与
