LazyInitializationException: не удалось инициализировать прокси - нет сеанса в Spring и Hibernate

Я получаю эту ошибку: «org.hibernate.LazyInitializationException: не удалось инициализировать прокси - нет сеанса» в моем веб-приложении. Я использую Spring и Hibernate, и я выполняю запросы с помощью "sessionFactory.getCurrentSession()".LazyInitializationException: не удалось инициализировать прокси - нет сеанса в Spring и Hibernate

Я много читал об этой проблеме, поэтому я попытался найти ответы, которые я нашел, но это не сработает. В настоящее время я использую «OpenSessionInViewFilter» и «OpenSessionInViewInterceptor».

Прилагаю файлы конфигурации.

Заранее спасибо.

Приложить трассировку стека. –

ОК, я обновил вопрос – Juanjo

Ну, я хотел, чтобы трассировка стека могла определить, является ли источник потоком HTTP-запроса. Вам нужно вставить немного больше. –

Похоже, вы начинаете поток (StackTrace коротка , не имеет никакого кода обработки сервлета и начинается с метода run), а затем манипулирует объектами, загруженными спящим режимом. Поскольку hibernate связывает его сеансы с потоками выполнения, он не может найти сеанс, связанный с потоком, который вы начали.

Вы должны:

Не начать новую тему. Или
Загрузите объекты в поток, который ими управляет (только пропускайте идентификаторы из одного потока в другой, а не загруженные объекты). Или
Загрузите объекты полностью, прежде чем передавать объекты в поток, который ими управляет.

Спасибо! что, похоже, работает – Juanjo
