Spring boot RabbitMQ Producer/Consumer Demo

Demo project for producer/consumer with spring boot and rabbitmq covering basic communication and also some common patterns like routing, TTL and dead letter queue.

RabbitMQ

this demo depends on a local or docker installation of rabbitmq available on localhost:5672 .
suggested: https://hub.docker.com/_/rabbitmq/

All rabbitmq configuration is done by the code once it is started.

Executing

you can simply run the projects rabbitmq-consumer and rabbitmq-producer on the IDE.

Or on command line with:

• mvn clean install on the root folder
• mvn spring-boot:start on each project folder

Once they are running you can use:

• http://localhost:8081/producer to create a new message
• http://localhost:8080/consumer to see the list of consumed messages.

Each produced message will be sent to a exchange that routes them towards two queues:

• topic.queue: a topic queue where the messages will be available for the consumer
• ttl.queue: a TTL queue, where the message are suppose to go to a Dead letter queue after 30s.

The message with ID 5 will fail and will also be sent to the Dead letter queue.
