V2AS问路
SpringBoot RabbitMQ 实战解决项目中实践
阅读原文时间：2023年08月16日阅读：1

  • 1.1 环境准备

    Springboot 1.5.6.RELEAS
    Springcloud Dalston.SR2

  • 1.2 交换机类型

交换机是用来发送消息的AMQP实体。交换机拿到一个消息之后将它路由给一个或零个队列。它使用哪种路由算法是由交换机类型和被称作绑定（bindings）的规则所决定的。AMQP 0-9-1的代理提供了四种交换机

Name（交换机类型） Default pre-declared names（预声明的默认名称） 
Direct exchange（直连交换机） (Empty string) and amq.direct 
Fanout exchange（扇型交换机） amq.fanout 
Topic exchange（主题交换机） amq.topic 
Headers exchange（头交换机） amq.match (and amq.headers in RabbitMQ)

  • 1.3 绑定

绑定（Binding）是交换机（exchange）将消息（message）路由给队列（queue）所需遵循的规则。如果要指示交换机“E”将消息路由给队列“Q”，那么“Q”就需要与“E”进行绑定。绑定操作需要定义一个可选的路由键（routing key）属性给某些类型的交换机。路由键的意义在于从发送给交换机的众多消息中选择出某些消息，将其路由给绑定的队列。

打个比方：

队列（queue）是我们想要去的位于纽约的目的地 
交换机（exchange）是JFK机场 
绑定（binding）就是JFK机场到目的地的路线。能够到达目的地的路线可以是一条或者多条 
拥有了交换机这个中间层，很多由发布者直接到队列难以实现的路由方案能够得以实现，并且避免了应用开发者的许多重复劳动。

如果AMQP的消息无法路由到队列（例如，发送到的交换机没有绑定队列），消息会被就地销毁或者返还给发布者。如何处理取决于发布者设置的消息属性。

  • 1.4 ack机制

RabbitMq默认是ack机制：no-ack的方式

执行一个任务可能需要花费几秒钟，你可能会担心如果一个消费者在执行任务过程中挂掉了。一旦RabbitMQ将消息分发给了消费者，就会从内存中删除。在这种情况下，如果正在执行任务的消费者宕机，会丢失正在处理的消息和分发给这个消费者但尚未处理的消息。

实际项目需要手动ack机制 - 见下问实战代码

  • 1.5 消息重复消费

用户在停止查询时，会导致消费者进程被杀死，因此ACK状态码未反馈至MQ，从而消息一直存留在MQ中，当新的消费者启动时会重新消费；

接受消息后-消费消息前，db或者redis nosql检查消息消费状态 - 见下问实战代码
