Core Concepts of Message Queues Message queues (MQ) facilitate asynchronous communication between disparate systems or components. By introducing an intermediary, producers and consumers operate independently, eliminating the need for direct synchronous connections. Fundamental Mechanics Production:...

To support multiple brokers, define separate ConnectionFactory, RabbitTemplate, RabbitAdmin, and listener container factory beans for each broker and mark one as primary. Conf...
RabbitMQ transports raw bytes. Too exchange domain objects as JSON, you can serialize manually or configure Spring AMQP to handle JSON automatically for both producers and consumers. Manual JSON serialization with ObjectMapper You can convert a POJO to JSON yourself and publish the resulting bytes....
