public class JndiDestinationResolver
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 void setCache(boolean cache)
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.
public void setFallbackToDynamicDestination(boolean fallbackToDynamicDestination)
Turn this flag on to enable transparent fallback to dynamic destinations.
public void setDynamicDestinationResolver(DestinationResolver dynamicDestinationResolver)
DestinationResolver
to use when falling back to dynamic
destinations.
The default is Spring's standard DynamicDestinationResolver
.
