Class ConsumerChannelRegistry

java.lang.Object

org.springframework.amqp.rabbit.connection.ConsumerChannelRegistry

public final class ConsumerChannelRegistry
extends Object

Consumers register their primary channels with this class. This is used to ensure that, when using transactions, the resource holder doesn't close the primary channel being used by the Consumer. This was previously in ConnectionFactoryUtils, but it caused a class tangle with RabbitResourceHolder.

Since:

1.2

Method Details

registerConsumerChannel

public static void registerConsumerChannel(com.rabbitmq.client.Channel channel,
 ConnectionFactory connectionFactory)

If a listener container is configured to use a RabbitTransactionManager, the consumer's channel is registered here so that it is used as the bound resource when the transaction actually starts. It is normally not necessary to use an external transaction manager because local transactions work the same in that the channel is bound to the thread. This is for the case when a user happens to wire in a RabbitTransactionManager.

Parameters:

channel - The channel to register.

connectionFactory - The connection factory.

unRegisterConsumerChannel

public static void unRegisterConsumerChannel()

See registerConsumerChannel. This method is called to unregister the channel when the consumer exits.

getConsumerChannel

@Nullable
public static com.rabbitmq.client.Channel getConsumerChannel()

See registerConsumerChannel. This method is called to retrieve the channel for this consumer.

Returns:

The channel.

getConsumerChannel

@Nullable
public static com.rabbitmq.client.Channel getConsumerChannel(ConnectionFactory connectionFactory)

See registerConsumerChannel. This method is called to retrieve the channel for this consumer if the connection factory matches.

Parameters:

connectionFactory - The connection factory.

Returns:

The channel.
