rabbitmq详解(rabbitmq消息模型怎么选择)

RabbitMQ6种消息模型简单队列

在简单队列中有三种角色

①生产者 P（消息的产生方）②消息队列（queue用来存放生产者所发送的消息，容量大小依据服务器存储大小）③消费者 C（消息的使用方）不足之处：生成者发送的消息数量很大，大于消费者的接收数量，就容易将队列强制刷新，丢失消息。

工作队列

在工作队列中有三种角色

①生产者 P（消息的产生方）②消息队列（queue用来存放生产者所发送的消息，容量大小依据服务器存储大小）③消费者 C（有多个消息的使用方）

第一种循环调度(Round-robin dispatching)

特点：有两个消费者，当一个消费者接收消息后，才到另一个消费者接收消息，以此类推。

在路由队列中有四种角色

①生产者 P（消息的产生方）②消息队列（queue用来存放生产者所发送的消息，容量大小依据服务器存储大小）③消费者 C（多个消息的使用方）④交换机特点：可以根据不同的routerkey去向不同的消息队列发送消息，可以指定那些消费者可以接收到消息。

主题队列

在发布与订阅队列中有四种角色

①生产者 P（消息的产生方）②消息队列（queue用来存放生产者所发送的消息，容量大小依据服务器存储大小）③消费者 C（多个消息的使用方）④交换机特点：主题队列集合了所有的队列模型的特点，可以实现所有队列模型的功能，是最常用的队列模型。*与#的讲解：*只能匹配一个，而#可以匹配零个或多个。
