Spring components for AMQP-based messaging.

The Spring AMQP project applies core Spring concepts to the development of AMQP-based messaging solutions. It provides a "template" as a high-level abstraction for sending and receiving messages. It also provides support for Message-driven POJOs. Its libraries facilitate management of AMQP resources while promoting the use of dependency injection and declarative configuration. In all of these cases, you will see similarities to the JMS support in the Spring Framework.

The spring-amqp sub-project is a general abstraction, with spring-rabbit being the implementation for RabbitMQ.
