For example, if you use SimpleMessageListner, one consumer corresponds to one thread. I would like to modify the message and publish it to a new exchange/queue. Some converters, such as the SimpleMessageConverter use the payload type and set the content type header appropriately. Here's how you can effectively test such methods using the Spring Test framework and the Mockito library. In this tutorial of the HOW TO series, I am going to give you a practical example of using RabbitMQ messaging configuration inside a Spring Boot application. 174k 14 14 gold Consume RabbitMQ message by all @RabbitListener-s in Spring Boot. 9. stream. Those methods are quite useful for request-reply scenarios, since they handle the configuration of the necessary reply-to property before sending and can listen for I’ve implemented RabbitMQ into my Spring Boot application to set up a messaging queue system and I believed it would be an excellent idea to promptly transform this into a blog post 🙂 Let’s explain how to create a simple Spring Boot RabbitMQ Producer and Consumer Workflow. auto-startup seems straightforward, there can be some unexpected behavior.
