Я занимаюсь службой REST с использованием Spring + Hibernate и пытается настроить транзакцию. Когда я сохраняю в аннотированной аннотации @Transactional Hibernate, не генерирует запрос с инструкцией INSERT. Только получает новый идентификатор. Это журнал:@Transactional не генерирует INSERT в базе данных
Hibernate: select next_val as id_val from hibernate_sequence for update
Hibernate: update hibernate_sequence set next_val= ? where next_val=?

Помогите, пожалуйста, найти то, что это неправильно. Когда я делаю операцию delete, он работает правильно и удаляет объект.
