RabbitConfiguration. In spring boot, default thread pool size is 200. 5. Sharing of the connection is possible since the “unit of work” for messaging with AMQP is actually a “channel” (in some ways, this is similar to the relationship between a connection and a session in JMS). Consume RabbitMQ message by all @RabbitListener-s in Spring Boot. The RabbitMQ Listener listens to RabbitMQ Queue for any incoming messages. Note that there is also a ConnectionFactory in the native Java Rabbit client. We setup our profiles for executing the topics as the choice of tut5 or topics. The spring doc says: "If the evaluation context has been configured with a bean resolver it is possible to lookup beans from an expression using the (@) symbol.
