Catch an SQL Exception with Spring Data JPA

Question

The following methods tries to write data to DB ( firmRepository.save() ) and to ElasticSearch ( firmSearchRepository.save() ).

The problem is that I do not want to write to ES repository if the DB save failed. I am trying to catch the exception with DataAccessException , but through my tests I see that such exceptions as unique constraint violation -> get through and persistence in ElasticSearch still executes.

@Override
public FirmDTO save (FirmDTO firmDTO) {
    log.info("Database Request to save Firm: {}", firmDTO.getFirmId());
    Firm firm = firmMapper.firmDTOtoFirm(firmDTO);
    try {
        firm = firmRepository.save(firm);
        firmSearchRepository.save(firm);
        return firmMapper.firmToFirmDTO(firm);
    } catch (DataAccessException ex) {
        log.error(ex.getLocalizedMessage());
        return null;
    }
}

Is there way to catch those specific exceptions related to SQL?

Answer 1

Using the saveAndFlush() JPA repository method made catching Spring Data exceptions possible.

@Override
    @Transactional
    public FirmDTO save (FirmDTO firmDTO) {
        log.info("Database Request to save Firm: {}", firmDTO.getFirmId());
        Firm firm = firmMapper.firmDTOtoFirm(firmDTO);
        try {
            firm = firmRepository.saveAndFlush(firm);
            firmSearchRepository.save(firm);
            return firmMapper.firmToFirmDTO(firm);
        } catch (DataAccessException ex) {
            log.error("my exception");
            log.error(ex.getLocalizedMessage());
            return null;
        }
    }
