Class JndiDestinationResolver

  org.springframework.jndi.JndiAccessor
      org.springframework.jndi.JndiLocatorSupport
          org.springframework.jms.support.destination.JndiDestinationResolver

All Implemented Interfaces:

DestinationResolver

public class JndiDestinationResolver
extends JndiLocatorSupport
implements DestinationResolver

DestinationResolver implementation which interprets destination names as JNDI locations (with a configurable fallback strategy).

Allows for customizing the JNDI environment if necessary, for example specifying appropriate JNDI environment properties.

Dynamic queues and topics get cached by destination name. As a consequence, you need to use unique destination names across both queues and topics. Caching can be turned off through the "cache" flag.

Note that the fallback to resolution of dynamic destinations is turned off by default. Switch the "fallbackToDynamicDestination" flag on to enable this functionality.

public JndiDestinationResolver()

Method Detail

setCache

public void setCache(boolean cache)

Set whether to cache resolved destinations. Default is "true".

This flag can be turned off to re-lookup a destination for each operation, which allows for hot restarting of destinations. This is mainly useful during development.

Note that dynamic queues and topics get cached by destination name. As a consequence, you need to use unique destination names across both queues and topics.

setFallbackToDynamicDestination

public void setFallbackToDynamicDestination(boolean fallbackToDynamicDestination)

Set whether this resolver is supposed to create dynamic destinations if the destination name is not found in JNDI. Default is "false".

Turn this flag on to enable transparent fallback to dynamic destinations.

See Also:

setDynamicDestinationResolver(org.springframework.jms.support.destination.DestinationResolver)

setDynamicDestinationResolver

public void setDynamicDestinationResolver(DestinationResolver dynamicDestinationResolver)

Set the DestinationResolver to use when falling back to dynamic destinations.

The default is Spring's standard DynamicDestinationResolver.

resolveDestinationName

public Destination resolveDestinationName(Session session,
                                          String destinationName,
                                          boolean pubSubDomain)
                                   throws JMSException

Description copied from interface: DestinationResolver

Resolve the given destination name, either as located resource or as dynamic destination.

Specified by:

resolveDestinationName in interface DestinationResolver

Parameters:

session - the current JMS Session

destinationName - the name of the destination

pubSubDomain - whether the domain is pub-sub, else P2P

Returns:

the JMS destination (either a topic or a queue)

Throws:

JMSException - if resolution failed
