/**
* Obtain a Hibernate Session, either from the current transaction or a new one. The latter is

* <p><b>Note that this is not meant to be invoked from HibernateTemplate code but rather just in
* plain Hibernate code.</b> Either rely on a thread-bound Session or use it in combination with
* {@link #releaseSession}.
*
* <p>In general, it is recommended to use {@link #getHibernateTemplate() HibernateTemplate},
* either with the provided convenience operations or with a custom {@link
* org.springframework.orm.hibernate3.HibernateCallback} that provides you with a Session to work
* on. HibernateTemplate will care for all resource management and for proper exception
* conversion.
*
* @param allowCreate if a non-transactional Session should be created when no transactional
* Session can be found for the current thread
* @return the Hibernate Session
* @throws DataAccessResourceFailureException if the Session couldn't be created
* @throws IllegalStateException if no thread-bound Session found and allowCreate=false
