RabbitMQ工作模式详解，以及Java实现

RabbitMQ共有六种工作模式：简单模式（Simple）、工作队列模式（Work Queue）、发布订阅模式（Publish/Subscribe）、路由模式（Routing）、通配符模式（Topics）、远程调用模式（RPC，不常用，不做讲解说明）

一、简单模式（Simple）

特点：①一个生产者对应一个消费者，通过队列进行消息传递。

       ②该模式使用direct交换机，direct交换机是RabbitMQ默认交换机。

图解：

二、工作队列模式（Work Queue）

与简单模式相比，工作队列模式(Work Queue)多了一些消费者，该模式也使用direct交换机，应用于处理消息较多的情况。特点如下：

①一个队列对应多个消费者。

②一条消息只会被一个消费者消费。

③消息队列默认采用轮询的方式将消息平均发送给消费者。

图解：

三、发布订阅模式（Publish/Subscribe）

在开发过程中，有一些消息需要不同消费者进行不同的处理

特点：

①生产者将消息发送给交换机，交换机将消息转发到绑定此交换机的每个队列中。

②工作队列模式的交换机只能将消息发送给一个队列，发布订阅模式的交换机能将消息发送给多个队列。发布订阅模式使用fanout交换机。

图解

四、路由模式（Routing）

使用发布订阅模式时，所有消息都会发送到绑定的队列中，但很多时候，不是所有消息都无差别的发布到所有队列中。特点：

①每个队列绑定路由关键字RoutingKey

②生产者将带有RoutingKey的消息发送给交换机，交换机根据RoutingKey转发到指定队列。路由模式使用direct交换机。

图解：

五、 通配符模式（Topics）

通配符模式(Topic)是在路由模式的基础上，给队列绑定带通配符的路由关键字，只要消息的RoutingKey能实现通配符匹配，就会将消息转发到该队列。通配符模式比路由模式更灵活，使用topic交换机。

通配符规则：

①消息设置RoutingKey时，RoutingKey由多个单词构成，中间以

.

分割。

②队列设置RoutingKey时，

#

可以匹配任意多个单词，

*

可以匹配任意一个单词。

六、Java实现五种模式
