There are multiple patterns to achieve event-driven Publish Subscribe Pattern. consumer. multiple consumers in a single queue in ActiveMQ. A message can have multiple consumers and consumers will get the messages only after it gets subscribed and consumers need to remain active in order to get new messages. Because the broker is going to loadbalance messages to the available consumers, we have no guarantee that the sequences of messages will be processed on the same thread. Enough talking about Reactive Programming… Now let’s move on to the Spring Boot Functional Reactive programming example. false. camel. The big difference between your code and the example is in the XML config example that myTargetConnectionFactory is actually a bean managed by Spring. Once you have been through the tutorials (or if you want to skip ahead), you may wish to read an Introduction to RabbitMQ Concepts and browse our AMQP 0-9-1 Quick Reference Guide. .
