Hibernate & Spring - org.hibernate.PropertyAccessException: не удалось установить значение поля [1] по отражению

0 голосов
/ 26 февраля 2020

Я новичок в Spring и попытался включить работающий проект Hibernate в среду Spring. Проекты работают соло отлично, но не в сочетании. Сначала я попытался выполнить свой тест Hibernate (последний фрагмент кода) в основном перед SpringApplikation.run (), но он был выполнен дважды. Затем я прочитал, что вы должны пометить класс как @Component, если я хочу получить его экземпляр при запуске приложения - без успеха. Любые предложения, как решить эту проблему? (:

это вывод моей консоли:

        session.getTransaction().commit();
        session.refresh(notification);

}

my попробуйте инициализировать hibernate: 

@Component
public class DatabaseStarter {

    @EventListener(ContextRefreshedEvent.class)
    public void contextRefreshedEvent() {
        init();
    }

    private void init() {
        HibernateConfigurator hibernateConfigurator = new HibernateConfigurator();
        Session session = hibernateConfigurator.getSession();

        NotificationDao notificationDao = new NotificationDao();
        notificationDao.create(session, "test_name", "test_trigger", "EMAIL", "test_message");
    }

}

Спасибо за помощь! (=

Редактировать: у меня есть решение. Это дико и жестоко, но оно работает. Я перешел из Hibernate на JPA и имею больше никаких проблем.

В PostgreSQL автоинкремент обрабатывается с использованием псевдотипа SERIAL, и этот псевдотип SERIAL создает последовательность. Последовательности аналогичны, но не идентичны концепции AUTO_INCREMENT в MySQL. изменить код, как показано ниже 

@Id @GeneratedValue(strategy = GenerationType.SEQUENCE)
    @Column(name = "ID")
    private Long id;
