Class HibernateExceptionTranslator
- java.lang.Object
- org.springframework.orm.hibernate4.HibernateExceptionTranslator
- All Implemented Interfaces:
PersistenceExceptionTranslator
- Direct Known Subclasses:
LocalSessionFactoryBean
public class HibernateExceptionTranslator extends Object implements PersistenceExceptionTranslator
PersistenceExceptionTranslator
capable of translatingHibernateException
instances to Spring'sDataAccessException
hierarchy.Extended by
LocalSessionFactoryBean
, so there is no need to declare this translator in addition to aLocalSessionFactoryBean
.When configuring the container with
@Configuration
classes, a@Bean
of this type must be registered manually.- Since:

Method Detail
translateExceptionIfPossible
public DataAccessException translateExceptionIfPossible(RuntimeException ex)
Description copied from interface:PersistenceExceptionTranslator
Translate the given runtime exception thrown by a persistence framework to a corresponding exception from Spring's genericDataAccessException
hierarchy, if possible.Do not translate exceptions that are not understood by this translator: for example, if coming from another persistence framework, or resulting from user code or otherwise unrelated to persistence.
Of particular importance is the correct translation to DataIntegrityViolationException, for example on constraint violation. Implementations may use Spring JDBC's sophisticated exception translation to provide further information in the event of SQLException as a root cause.
- Specified by:
translateExceptionIfPossible
in interfacePersistenceExceptionTranslator
- Parameters:
ex
- a RuntimeException to translate- Returns:
- the corresponding DataAccessException (or
null
if the exception could not be translated, as in this case it may result from user code rather than from an actual persistence problem) - See Also:
