We are pleased to announce the availability of the Spring AMQP (for Java) 1.3.0.RC1 release candidate. It is expected to be the final candidate before GA.

The release includes some significant new features, including:

• Listener Container

• The listener container concurrency can be changed without first stopping the container and the listeners will be adjusted accordingly

• The listener container can dynamically adjust the concurrent consumers, based on workload

• The listener container now supports consumer priority (with RabbitMQ 3.2.x or greater)

• The listener container now supports the configuration of an exclusive consumer

• Rabbit Template

• The RabbitTemplate now has several convenient receiveAndReply methods

• The RabbitTemplate can now be configured with a RetryTemplate, enabling clients to not have to deal directly with broker connectivity issues.

• Connection Factory

• The Connection Factory can now cache connections rather than all users sharing the same connection (and, since M2, channels can be cached within cached connections)

• There is now a SimpleRoutingConnectionFactory to determine which connection factory to use at runtime

• Other Key Features

• A fluent Java API is now provided to build a Message (and MessageProperties)

• A fluent Java API is now provided for building a listener container retry interceptor

• When using a retry interceptor, a new RepublishMessageRecoverer is available to republish failed messages (with stack trace) to another exchange
