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 generic DataAccessException hierarchy, if possible.

Do not translate exceptions that are not understand by this translator: for example, if coming from another persistence framework, or resulting from user code and 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 interface PersistenceExceptionTranslator

Parameters:

ex - a RuntimeException thrown

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 an actual persistence problem)

convertHibernateAccessException

protected DataAccessException convertHibernateAccessException(HibernateException ex)

Convert the given HibernateException to an appropriate exception from the org.springframework.dao hierarchy.

Parameters:

ex - HibernateException that occured

Returns:

a corresponding DataAccessException
