We will soon be releasing the first milestone of our Spring AMQP project. That includes support at the same basic level as Spring's JMS support (AmqpTemplate, SimpleMessageListenerContainers for Message-driven POJOs, MessageConverter strategies, and more). We will be providing Spring Integration Channel Adapters, Gateways, etc. that will build on top of that functionality.

We're going to be collaborating with OpenCredo on the project I mentioned above, and that project is actually quite active already. However, as I mentioned, we're just now approaching the first milestone release. We'll be moving to Git any moment now, but until it's moved, you can browse the current codebase here: https://src.springsource.org/svn/se-amqp/trunk/ (after the move it will be at git.springsource.org/spring-amqp)

As the lead of Spring Integration, I'm a bit biased. That said, if your main concern is having a solid (and "mature" I might add) Spring foundation with implementations that are absolutely consistent with Spring, then Spring Integration is probably the best choice (and 2.0 GA is only a couple months away).

Hopefully this question has been answered above. Let me know if there is anything that I missed.
