Since we are developing a spring application integrated with activemq, we also need to add spring-boot-starter-activemq dependency. Our opinionated auto-configuration of the Camel context auto-detects Camel routes available in the Spring context and registers the key Camel utilities (like producer template, consumer template and the type converter) as beans. After the Spring Boot application is started, the Queue and Exchange will be created automatically and bound to each other. At the end of it, you will learn how to send messages from a generic Spring Boot application and from a Spring Boot REST Controller. Home » org.springframework.boot » spring-boot-starter-amqp » 2.3.5.RELEASE Spring Boot Starter AMQP » 2.3.5.RELEASE Starter for using Spring AMQP and Rabbit MQ In order to start, we will create a project which uses artemis dependencies. The only thing you need to do to make use of AMQP with RabbitMQ in Spring Boot is to include the corresponding starter dependency (AMQP) and the Jackson libraries (to work with JSON): Because the Receiver class is a POJO, it needs to be wrapped in the MessageListenerAdapter, where you specify that it invokes receiveMessage.
