We are pleased to announce the availability of the Spring AMQP (for Java) 1.3.1.RELEASE.

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

• The listener container now supports auto-delete queues; redeclaring them if necessary when starting

• 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
