Doc from org.springframework.dao.support.PersistenceExceptionTranslator.translateExceptionIfPossible.

Translate the given runtime exception thrown by a persistence framework to a corresponding exception from Spring's generic org.springframework.dao.DataAccessException 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.

Parameters
ex:RuntimeException

a RuntimeException to translate

Returns:DataAccessException

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)
