Спящий PropertyAccessException Во время OneToOne Mapping

У меня есть четыре сущности RoomNight, BookingCorporateDetails, BookingDiscountDetails и BookingDetails, в котором BookingCorporateDetails, BookingDiscountDetails и BookingDetails относится к RoomNight на колонке (room_night_booking_id).Спящий PropertyAccessException Во время OneToOne Mapping

Я пытаюсь создать соединение внешнего ключа на BookingCorporateDetails, BookingDiscountDetails и BookingDetails, чтобы сохранить/получить/удалить все данные вместе. Я могу сохранить данные в базе данных, но когда я пытаюсь получить, я получаю Hibernate PropertyAccessException. Структура сущность таблица -

Я думаю, причина в том, вы отображение вашего roomNightBookingId в поле Строки в AbstractBookingEntity.java. Вы в этом уверены? –

@ Дайв Да. RoomNightBookingId - это буквенно-цифровой идентификатор, поэтому это строка. –

Проверить room_night_booking_id тип столбца в таблице RoomNightEntity (room_night, если я вижу его правильно.). Это не должно быть числовым типом.

Похоже Java пытается разрешить класс Long, а затем пытается присвоить Long к String собственности.

Это строковый тип, а не число. Это буквенно-цифровой идентификатор, на котором я пытаюсь присоединиться. –

Вы упомянули, что вы «выполняете код получения/удаления RoomNightEntity». Предполагая, что вы ссылаетесь на объект, а не на идентификатор (например, getRoomNightEntity(), а не getRoomNightEntityId() - пытались ли вы удалить поле roomNightBookingId из AbstractBookingEntity? Похоже, вы делаете две ссылки на roomNightBooking один по id и один по объекту в то время как требуется только один. Сообщение об ошибке явно ссылается на поле roomNightBookingId (свойство [...] RoomNightEntity # roomNightBookingId), что странно, если вы вызываете код получателя/удаления. Если вы вызываете getRoomNightEntityId(), вы можете захотеть чтобы прокомментировать поле/методы сущности в подклассах, просто посмотрите, какое влияние будет.

Также может быть ошибка безопасности в соответствии с документом btw.

С наилучшими пожеланиями Марка

Я вызываю getRoomNightEntity(). И я не пробовал удалить поле из класса Abstract, но теперь попробую точно. –
