* Interface to be implemented by transparent resource proxies that need to be
* considered as equal to the underlying resource, for example for consistent
* lookup key comparisons. Note that this interface does imply such special
* semantics and does not constitute a general-purpose mixin!
*
* <p>Such wrappers will automatically be unwrapped for key comparisons in
* {@link org.springframework.transaction.support.TransactionSynchronizationManager}.
*
* <p>Only fully transparent proxies, e.g. for redirection or service lookups,
* are supposed to implement this interface. Proxies that decorate the target
* object with new behavior, such as AOP proxies, do <i>not</i> qualify here!
