RabbitMQ Tutorials
------------------
This project implements each of the [6 RabbitMQ Tutorials][1] using Spring AMQP.
Each is a pair of spring boot applications.
For tutorials 1-5, run the `ReceiverApplication` followed by the `SenderApplication`.
For tutorial 6, run the `ServerApplication` followed by the `ClientApplication`.
You can run these within an IDE or use the Spring Boot maven plugin which launches the `Main` class which decides which app to run based on the `runner` system property.
$ mvn spring-boot:run -Drunner=tut1.Receiver &
$ mvn spring-boot:run -Drunner=tut1.Sender &
...
$ mvn spring-boot:run -Drunner=tut6.Server &
$ mvn spring-boot:run -Drunner=tut6.Client &
