public Class CachingDestinationResolverProxy<D>

extends Object
implements DestinationResolver<D>, InitializingBean
Class Inheritance
All Implemented Interfaces
org.springframework.beans.factory.InitializingBean, org.springframework.messaging.core.DestinationResolver
Type Parameters
<D>
the destination type
Imports
java.util.Map, java.util.concurrent.ConcurrentHashMap, org.springframework.beans.factory.InitializingBean, org.springframework.lang.Nullable, org.springframework.util.Assert
DestinationResolver implementation that proxies a target DestinationResolver, caching its resolveDestination results. Such caching is particularly useful if the destination resolving process is expensive (e.g. the destination has to be resolved through an external system) and the resolution results are stable anyway.
