Constructor Detail

ThreadChannelConnectionFactory

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

Construct an instance.

Parameters:

rabbitConnectionFactory - the rabbitmq connection factory.

Method Detail

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.

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

closeThreadChannel

public void closeThreadChannel()

Close the channel associated with this thread, if any.

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.

destroy

public void destroy()

Specified by:

destroy in interface DisposableBean

Overrides:

destroy in class AbstractConnectionFactory

prepareSwitchContext

@Nullable
public java.lang.Object prepareSwitchContext()

Call to prepare to switch the channel(s) owned by this thread to another thread.

Returns:

an opaque object representing the context to switch. If there are no channels or no open channels assigned to this thread, null is returned.

Since:
