Method Details

setDestinationResolver

public void setDestinationResolver(DestinationResolver destinationResolver)

Set the DestinationResolver that is to be used to resolve Destination references for this accessor.

The default resolver is a DynamicDestinationResolver. Specify a JndiDestinationResolver for resolving destination names as JNDI locations.

• DynamicDestinationResolver
• JndiDestinationResolver

getDestinationResolver

public DestinationResolver getDestinationResolver()

Return the DestinationResolver for this accessor (never null).

setPubSubDomain

public void setPubSubDomain(boolean pubSubDomain)

Configure the destination accessor with knowledge of the JMS domain used. Default is Point-to-Point (Queues).

This setting primarily indicates what type of destination to resolve if dynamic destinations are enabled.

Parameters:

pubSubDomain - "true" for the Publish/Subscribe domain (Topics), "false" for the Point-to-Point domain (Queues)

See Also:

• setDestinationResolver(org.springframework.jms.support.destination.DestinationResolver)

isPubSubDomain

public boolean isPubSubDomain()

Return whether the Publish/Subscribe domain (Topics) is used. Otherwise, the Point-to-Point domain (Queues) is used.

resolveDestinationName

protected Destination resolveDestinationName(Session session,
 String destinationName)
                                      throws JMSException

Resolve the given destination name into a JMS Destination, via this accessor's DestinationResolver.

Parameters:

session - the current JMS Session

destinationName - the name of the destination

Returns:

the located Destination

Throws:

JMSException - if resolution failed

See Also:

• setDestinationResolver(org.springframework.jms.support.destination.DestinationResolver)

protected Message receiveFromConsumer(MessageConsumer consumer,
 long timeout)
                               throws JMSException
