когда я пытаюсь записать в базу нового работника:
| Код |
public void save(Employee empl) {
logger.info("Saving Employee: " + empl.toString());
try {
getJpaTemplate().persist(empl);
getJpaTemplate().flush();
} catch (RuntimeException e) {
logger.error("Failed to save entity: " + empl.toString(), e);
throw e;
}
}

получаю такую ошибку:
