Interface HibernateOperations

All Known Implementing Classes:
HibernateTemplate
public interface HibernateOperations

Interface that specifies a basic set of Hibernate operations, implemented by 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.

Note that operations that return an Iterator (i.e. iterate(..)) are supposed to be used within Spring-driven or JTA-driven transactions (with HibernateTransactionManager, JtaTransactionManager, or EJB CMT). Else, the Iterator won't be able to read results from its ResultSet anymore, as the underlying Hibernate Session will already have been closed.

Note that lazy loading will just work with an open Hibernate Session, either within a transaction or within OpenSessionInViewFilter/ OpenSessionInViewInterceptor. Furthermore, some operations just make sense within transactions, for example: contains, evict, lock, flush, clear.

Method Detail

execute

Object execute(HibernateCallback action)
               throws DataAccessException
Execute the action specified by the given action object within a 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, i.e. 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.

Parameters:
action - callback object that specifies the Hibernate action
Returns:
a result object returned by the action, or null
Throws:
DataAccessException - in case of Hibernate errors
