/** |
||||||
|
* A simple {@link DestinationResolver} implementation for {@link Session}-based |
||||||
|
* destination resolution, caching {@link Queue} and {@link Topic} instances per |
||||||
|
* queue/topic name. In that sense, the destinations themselves also need to be |
||||||
|
* "simple": not Session-specific and therefore stable across an entire JMS setup. |
||||||
|
* |
||||||
|
* <p>This is the default resolver used by {@link org.springframework.jms.core.JmsClient} |
||||||
|
* and also {@link org.springframework.jms.core.JmsTemplate} and listener containers, |
||||||
|
* as of 7.0. For enforcing fresh resolution on every call, you may explicitly set a |
||||||
|
* {@link DynamicDestinationResolver} instead. |
