In the previous several articles, we introduced how to publish a simple message through RabbitMQ, then to work queue, multiple consumers to consume, and finally to work queue distribution and message response mechanism (ACK); These modes we shared before are all deleted from the queue after being consumed. Ideally, they will not be re consumed. ...
