Я пытаюсь реализовать операции CRUD для этого объекта с использованием Hibernate, но я получаю LazyEvaluationException. НЕТ ссылок. Его единственная 1 таблица в базе данных ... Я могу запросить, но когда я пытаюсь выпустить обновление, возникает исключение. Теперь у меня есть действительно наивная реализация, выглядит следующим образом:

Когда обновление вызываются не BAMM Нет сессии. Почему это происходит? GetAll преуспевает хорошо и плавно, но это все к нему. Все остальное возвращается в отсутствие ошибок сеанса в моих журналах.

Почему вы отмечаете свой метод как @Transactional и открываете/закрываете сеанс в каждом методе? – Maksym

заменить статический блок методом ранее(), а также добавить создание сеанса в конце его:

@Before 
public void before() {  
    Configuration configuration = new Configuration(); 
    configuration = configuration.configure(); 

    StandardServiceRegistryBuilder registryBuilder = new StandardServiceRegistryBuilder(); 
    registryBuilder = registryBuilder.applySettings(configuration.getProperties()); 

    StandardServiceRegistry registry = registryBuilder.build(); 
    sessionFactory = configuration.buildSessionFactory(registry); 
    session = sessionFactory.openSession(); 
}

и метод после того, как():

@After 
public void after { 
    session.close(); 
    sessionFactory.close(); 
}

И, конечно, удалите все открытые/закрытые сеансы в каждом тесте.

Хотя у меня нет этих аннотаций, я добавил два метода: OpenSession и CloseSession, которые я вызываю в методах PostConstruct и PreDestroy в моем bean-компоненте, которые решают проблему. Спасибо! – Wrath
