Add a PersistenceExceptionTranslator to the chained delegate list.
Return all registered PersistenceExceptionTranslator delegates (as array).
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.

exception could not be translated, as in this case it may result from
