All Implemented Interfaces:

org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.InitializingBean, org.springframework.context.Lifecycle, org.springframework.context.Phased, org.springframework.context.SmartLifecycle

public class ExtendedMessageListenerContainer
extends org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer

Specialization of the SimpleMessageListenerContainer that allows consumer to be registered as exclusive on a channel. This allows for active-passive setups, as a second consumer will fallback to retry-mode when a connection is failed. When the first connection is released, a retry will automatically succeed.

Method Detail

setConnectionFactory

public void setConnectionFactory(org.springframework.amqp.rabbit.connection.ConnectionFactory connectionFactory)

Overrides:

setConnectionFactory in class org.springframework.amqp.rabbit.connection.RabbitAccessor

setExclusive

public void setExclusive(boolean exclusive)

Sets whether the listener container created by this factory should be exclusive. That means it will not allow other listeners to connect to the same queue. If a non-exclusive listener is already connected to the queue, this listener is rejected.

Note that setting exclusive mode will force the use of a single concurrent consumer. Therefore, setting the concurrent consumers to a value larger than 1, will disable exclusive mode.

By default, listeners are exclusive.

Parameters:

exclusive - Whether the created container should be an exclusive listener

setConcurrentConsumers

public void setConcurrentConsumers(int concurrentConsumers)

Sets the number of concurrent consumers in this container. When larger than 1, this container will not operate in exclusive mode.

Overrides:

setConcurrentConsumers in class org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer

Parameters:

concurrentConsumers - The number of consumers to register on the queue
