      public final void addDelegate(PersistenceExceptionTranslator pet)
      Add a PersistenceExceptionTranslator to the chained delegate list.

      Return all registered PersistenceExceptionTranslator delegates (as array).

    • translateExceptionIfPossible

      public @Nullable 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 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 interface PersistenceExceptionTranslator
      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)
