public class HibernateExceptionTranslator extends Object implements PersistenceExceptionTranslator
PersistenceExceptionTranslator
capable of translating HibernateException
instances to Spring's DataAccessException
hierarchy. As of Spring 4.3.2 and
Hibernate 5.2, it also converts standard JPA PersistenceException
instances.
Extended by LocalSessionFactoryBean
, so there is no need to declare this
translator in addition to a LocalSessionFactoryBean
.
When configuring the container with @Configuration
classes, a @Bean
of this type must be registered manually.

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.
