Force Hibernate to read database and not return cached entity

Do the read within a new transaction.

For example:

...
MyDTO myDTO = fetchMyDTOById(daoId);
...
@Transactional(readOnly = true, propagation = Propagation.REQUIRES_NEW)
private MyDTO fetchMyDTOById(Long dtoId) {
    return repository.findById(dtoId);
}

session.refresh(entity) or entityManager.refresh(entity) (if you use JPA) will give you fresh data from DB.
