Class PooledChannelConnectionFactory

java.lang.Object

org.springframework.amqp.rabbit.connection.AbstractConnectionFactory

org.springframework.amqp.rabbit.connection.PooledChannelConnectionFactory

All Implemented Interfaces:

public class PooledChannelConnectionFactory
extends AbstractConnectionFactory
implements com.rabbitmq.client.ShutdownListener

A very simple connection factory that caches channels using Apache Pool2 GenericObjectPools (one for transactional and one for non-transactional channels). The pools have default configuration but they can be configured using a callback.

2.3

Constructor Details

PooledChannelConnectionFactory

public PooledChannelConnectionFactory(com.rabbitmq.client.ConnectionFactory rabbitConnectionFactory)

Construct an instance.

Parameters:

rabbitConnectionFactory - the rabbitmq connection factory.

Method Details

setPublisherConnectionFactory

public void setPublisherConnectionFactory(@Nullable
 AbstractConnectionFactory publisherConnectionFactory)

Description copied from class: AbstractConnectionFactory

Set a custom publisher connection factory; the type does not need to be the same as this factory.

Overrides:

setPublisherConnectionFactory in class AbstractConnectionFactory

Parameters:

publisherConnectionFactory - the factory.

setPoolConfigurer

public void setPoolConfigurer(BiConsumer<org.apache.commons.pool2.impl.GenericObjectPool<com.rabbitmq.client.Channel>,Boolean> poolConfigurer)

Add a consumer to configure the object pool. The second argument is true when called with the transactional pool.

Parameters:

poolConfigurer - the configurer.

isSimplePublisherConfirms

public boolean isSimplePublisherConfirms()

Description copied from interface: ConnectionFactory

Return true if simple publisher confirms are enabled.

Specified by:

isSimplePublisherConfirms in interface ConnectionFactory

Returns:

simplePublisherConfirms

setSimplePublisherConfirms

public void setSimplePublisherConfirms(boolean simplePublisherConfirms)

Enable simple publisher confirms.

Parameters:

simplePublisherConfirms - true to enable.

addConnectionListener

public void addConnectionListener(ConnectionListener listener)

Specified by:

addConnectionListener in interface ConnectionFactory

Overrides:

addConnectionListener in class AbstractConnectionFactory

createConnection

public Connection createConnection()
                            throws AmqpException

Specified by:

createConnection in interface ConnectionFactory

Throws:

AmqpException

resetConnection

public void resetConnection()

Close the connection(s). This will impact any in-process operations. New connection(s) will be created on demand after this method returns. This might be used to force a reconnect to the primary broker after failing over to a secondary broker.

Specified by:

resetConnection in interface ConnectionFactory

destroy

public void destroy()

Specified by:

destroy in interface DisposableBean

Overrides:

destroy in class AbstractConnectionFactory
