Changes in 1.5 Since 1.4

spring-erlang Is No Longer Supported

The spring-erlang jar is no longer included in the distribution. Use the RabbitMQ REST API instead.

CachingConnectionFactory Changes

Empty Addresses Property in CachingConnectionFactory

Previously, if the connection factory was configured with a host and port but an empty String was also supplied for addresses, the host and port were ignored. Now, an empty addresses String is treated the same as a null, and the host and port are used.

URI Constructor

The CachingConnectionFactory has an additional constructor, with a URI parameter, to configure the broker connection.

Connection Reset

A new method called resetConnection() has been added to let users reset the connection (or connections). You might use this, for example, to reconnect to the primary broker after failing over to the secondary broker. This does impact in-process operations. The existing destroy() method does exactly the same, but the new method has a less daunting name.

Properties to Control Container Queue Declaration Behavior

When the listener container consumers start, they attempt to passively declare the queues to ensure they are available on the broker. Previously, if these declarations failed (for example, because the queues didn’t exist) or when an HA queue was being moved, the retry logic was fixed at three retry attempts at five-second intervals. If the queues still do not exist, the behavior is controlled by the missingQueuesFatal property (default: true). Also, for containers configured to listen from multiple queues, if only a subset of queues are available, the consumer retried the missing queues on a fixed interval of 60 seconds.

The declarationRetries, failedDeclarationRetryInterval, and retryDeclarationInterval properties are now configurable. See Message Listener Container Configuration for more information.

Class Package Change

The RabbitGatewaySupport class has been moved from o.s.amqp.rabbit.core.support to o.s.amqp.rabbit.core.

DefaultMessagePropertiesConverter Changes

You can now configure the DefaultMessagePropertiesConverter to determine the maximum length of a LongString that is converted to a String rather than to a DataInputStream. The converter has an alternative constructor that takes the value as a limit. Previously, this limit was hard-coded at 1024 bytes. (Also available in 1.4.4).

@RabbitListener Improvements

@QueueBinding for @RabbitListener

The bindings attribute has been added to the @RabbitListener annotation as mutually exclusive with the queues attribute to allow the specification of the queue, its exchange, and binding for declaration by a RabbitAdmin on the Broker.

SpEL in @SendTo

The default reply address (@SendTo) for a @RabbitListener can now be a SpEL expression.

Multiple Queue Names through Properties

You can now use a combination of SpEL and property placeholders to specify multiple queues for a listener.

See Annotation-driven Listener Endpoints for more information.

Automatic Exchange, Queue, and Binding Declaration

You can now declare beans that define a collection of these entities, and the RabbitAdmin adds the contents to the list of entities that it declares when a connection is established. See Declaring Collections of Exchanges, Queues, and Bindings for more information.

RabbitTemplate Changes

reply-address Added

The reply-address attribute has been added to the <rabbit-template> component as an alternative reply-queue. See Request/Reply Messaging for more information. (Also available in 1.4.4 as a setter on the RabbitTemplate).

Blocking receive Methods

The RabbitTemplate now supports blocking in receive and convertAndReceive methods. See Polling Consumer for more information.

Mandatory with sendAndReceive Methods

When the mandatory flag is set when using the sendAndReceive and convertSendAndReceive methods, the calling thread throws an AmqpMessageReturnedException if the request message cannot be delivered. See Reply Timeout for more information.

Improper Reply Listener Configuration

The framework tries to verify proper configuration of a reply listener container when using a named reply queue.

See Reply Listener Container for more information.

RabbitManagementTemplate Added

The RabbitManagementTemplate has been introduced to monitor and configure the RabbitMQ Broker by using the REST API provided by its management plugin. See [management-rest-api] for more information.

Listener Container Bean Names (XML)

The id attribute on the <listener-container/> element has been removed. Starting with this release, the id on the <listener/> child element is used alone to name the listener container bean created for each listener element.

Normal Spring bean name overrides are applied. If a later <listener/> is parsed with the same id as an existing bean, the new definition overrides the existing one. Previously, bean names were composed from the id attributes of the <listener-container/> and <listener/> elements.

When migrating to this release, if you have id attributes on your <listener-container/> elements, remove them and set the id on the child <listener/> element instead.

However, to support starting and stopping containers as a group, a new group attribute has been added. When this attribute is defined, the containers created by this element are added to a bean with this name, of type Collection<SimpleMessageListenerContainer>. You can iterate over this group to start and stop containers.

Class-Level @RabbitListener

The @RabbitListener annotation can now be applied at the class level. Together with the new @RabbitHandler method annotation, this lets you select the handler method based on payload type. See Multi-method Listeners for more information.

SimpleMessageListenerContainer: BackOff Support

The SimpleMessageListenerContainer can now be supplied with a BackOff instance for consumer startup recovery. See Message Listener Container Configuration for more information.

Channel Close Logging

A mechanism to control the log levels of channel closure has been introduced. See Channel Close Logging.

Application Events

The SimpleMessageListenerContainer now emits application events when consumers fail. See Consumer Events for more information.

Consumer Tag Configuration

Previously, the consumer tags for asynchronous consumers were generated by the broker. With this release, it is now possible to supply a naming strategy to the listener container. See Consumer Tags.

Using MessageListenerAdapter

The MessageListenerAdapter now supports a map of queue names (or consumer tags) to method names, to determine which delegate method to call based on the queue from which the message was received.

LocalizedQueueConnectionFactory Added

LocalizedQueueConnectionFactory is a new connection factory that connects to the node in a cluster where a mirrored queue actually resides.

See Queue Affinity and the LocalizedQueueConnectionFactory.

Anonymous Queue Naming

Starting with version 1.5.3, you can now control how AnonymousQueue names are generated. See AnonymousQueue for more information.
