RabbitMQ Message distribution round robin and Message AcknowledgmentI. Message Distribution
Messages in RabbitMQ can only be stored in the Queue. The producer (P) produces messages and finally delivers them to the Queue. The consumer (C) can obtain and consume messages from the Queue.
Multiple consumers can subscribe to the same Queue. In this case, messages in the Queue will be evenly distributed to mul
A Preliminary Study on RabbitMQ
1. What is MQ?MQ is called Message Queue. MQ is a communication method for applications. Applications write and retrieve data (messages) for applications in the inbound and outbound queues to communicate with each other without dedicated connections. Message transmission refers to the communication between programs by sending data in messages, rather than by directly calling each other. Direct calls are usually used for

In the previous article we introduced the method of using RABBITMQ Java client to access RABBITMQ. However, in this way access to RABBITMQ, developers need to manage their own Connection,channel objects in the program, consumer object creation, destruction, this will be very inconvenient. Here we introduce the use of spring AMQP to connect
