  - - org.springframework.jms.support.destination.JndiDestinationResolver

All Implemented Interfaces:
CachingDestinationResolver, DestinationResolver
```
public class JndiDestinationResolver
extends JndiLocatorSupport
implements CachingDestinationResolver
```
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.

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`clearCache()`	Clear the entire destination cache.
`void`	`removeFromCache(String destinationName)`	Remove the destination with the given name from the cache (if cached by this resolver in the first place).
`Destination`	`resolveDestinationName(Session session, String destinationName, boolean pubSubDomain)`	Resolve the given destination name, either as located resource or as dynamic destination.
`void`	`setCache(boolean cache)`	Set whether to cache resolved destinations.
`void`	`setDynamicDestinationResolver(DestinationResolver dynamicDestinationResolver)`	Set the `DestinationResolver` to use when falling back to dynamic destinations.
`void`	`setFallbackToDynamicDestination(boolean fallbackToDynamicDestination)`	Set whether this resolver is supposed to create dynamic destinations if the destination name is not found in JNDI.
`protected void`	`validateDestination(Destination destination, String destinationName, boolean pubSubDomain)`	Validate the given Destination object, checking whether it matches the expected type.

```
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(@Nullable
                                          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 (may be null if the resolver implementation is able to work without it)
    destinationName - the name of the destination
    pubSubDomain - true if the domain is pub-sub, false if P2P
    Returns:
    the JMS destination (either a topic or a queue)
    Throws:
    JMSException - if the JMS Session failed to resolve the destination
  - validateDestination
```
protected void validateDestination(Destination destination,
                                   String destinationName,
                                   boolean pubSubDomain)
```
    Validate the given Destination object, checking whether it matches the expected type.
    Parameters:
    destination - the Destination object to validate
    destinationName - the name of the destination
    pubSubDomain - true if a Topic is expected, false in case of a Queue
  - removeFromCache
```
public void removeFromCache(String destinationName)
```
    Description copied from interface: CachingDestinationResolver
    Remove the destination with the given name from the cache (if cached by this resolver in the first place).
    To be called if access to the specified destination failed, assuming that the JMS Destination object might have become invalid.
    Specified by:
    removeFromCache in interface CachingDestinationResolver
    Parameters:
    destinationName - the name of the destination
  - clearCache
```
public void clearCache()
```
    Description copied from interface: CachingDestinationResolver
    Clear the entire destination cache.
    To be called in case of general JMS provider failure.
    Specified by:
    clearCache in interface CachingDestinationResolver
