Spring AMQP 1.3 Released

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
