Вопрос на который почти каждый кто работает с Hibernate знает ответ. А у меня ошибка лезет. Значитс - мне нужно сделать каскадное обновление данных. Сейчас получаю такую вот ошибочку... Что-то оч большой трейс.. забрасываю в конец. Вот так сохраняю или делаю апдейт. | Код |
public void saveGame(SaveParams saveParams) {
int res = 0;
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
Query query = session.createQuery("from SaveParams where serverName = :sName ");
query.setParameter("sName", saveParams.getServerName());
List listOfSaveParams = query.list();
if (listOfSaveParams.size()==0) {
session.save(saveParams);
} else {
SaveParams result = (SaveParams) listOfSaveParams.get(0);
Query q1 = session.createSQLQuery("update SaveParams set serverName = :sName ");
q1.setParameter("sName", saveParams.getServerName());
res = q1.executeUpdate();
}
session.getTransaction().commit();
}

Вот так выглядит класс. | Код |
