/**
* Implementation of Hibernate 3.1's CurrentSessionContext interface
* that delegates to Spring's SessionFactoryUtils for providing a
* Spring-managed current Session.
*
* Used by Spring's LocalSessionFactoryBean if told to not expose a
* transaction-aware SessionFactory proxy. LocalSessionFactoryBean's default
* is still SessionFactory proxying, though, mainly to remain compatible with
* Hibernate 3.0 as well. Turn the "exposeTransactionAwareSessionFactory" flag
* to "false" to expose the raw Hibernate 3.1 CurrentSessionContext mechanism.
*
*
This CurrentSessionContext implementation can be specified in custom
* SessionFactory setup through the "hibernate.current_session_context_class"
* property, with the fully qualified name of this class as value.
