public interface HibernateOperations
HibernateTemplate
. Not often used, but a useful
option to enhance testability, as it can easily be mocked or stubbed.
Defines HibernateTemplate
's data access methods that
mirror various Session
methods. Users are
strongly encouraged to read the Hibernate Session
javadocs
for details on the semantics of those methods.

<T> T execute(HibernateCallback<T> action) throws DataAccessException
Session
.
Application exceptions thrown by the action object get propagated to the caller (can only be unchecked). Hibernate exceptions are transformed into appropriate DAO ones. Allows for returning a result object, that is a domain object or a collection of domain objects.
Note: Callback code is not supposed to handle transactions itself!
Use an appropriate transaction manager like
HibernateTransactionManager
. Generally, callback code must not
touch any Session
lifecycle methods, like close,
disconnect, or reconnect, to let the template do its work.
