Сериализация сущности JPA требует менеджера сущностей, ленивая загрузка не должна быть проблемой

1 голос
/ 21 мая 2011

Я получаю исключение "Сессия закрыта".При сериализации сущности JPA2, поддерживаемой hibernate для JSON.

Я мог понять, была ли отложенная загрузка, но нет столбцов соединения.

Кроме того, инструмент, который сериализует объект в JSON, позволяетвключить и исключить параметры, просто вы можете явно указать, какие части объекта будут или не будут сериализованы.Если я вручную включу все свойства объекта, то сериализация будет работать.Однако это очень утомительно, и я должен быть в состоянии сказать «objectName. *» И рекурсивно сериализовать его.

Единственное, что имеет смысл, так это то, что каким-то образом объект обладает каким-то свойством, которое вызывает диспетчер сущностей гибернации, но не является одним из видимых свойств класса?

Следующая ошибкараспечатано Struts2:

Похоже, что сериализатор JSON обнаружил ленивый прокси и пытается сериализовать свой обработчик ленивой инициализации, полученный при вызове HibernateProxy.getHibernateLazyInitializer().Вы можете попытаться сконфигурировать ваш сериализатор JSON, чтобы игнорировать этот метод.
