Struts2 Hibernate (возвращает список, в результате чего Hibernate извлекает данные из всех отношений)

1 голос
/ 31 июля 2010

Я создаю зависимые выпадающие списки, используя Struts2 jquery. Проблема в том, что метод getLobList () внутри класса действия вызывает hibernate для получения всех данных для объекта. Если я удаляю этот метод получения, эти журналы не создаются. Почему это происходит, чтобы это исправить?

Я столкнулся с той же проблемой.

Это происходит потому, что плагин JSON, отвечающий за создание вашего результата JSON, пытается сериализовать весь объект со всеми его связями.

Чтобы предотвратить это, я предлагаю вам создать оболочку для ваших данных (то есть вы создаете класс LobJSONWrapper, содержащий ТОЛЬКО ключ и значение, которое вы хотите использовать), и возвращаете список экземпляров оболочки вместо Lob экземпляров.

Вы также можете запретить плагину JSON сериализовать поле: см. «Исключение свойств» здесь

вам просто нужно удалить ваш сервисный объект из результирующего объекта, для этого вам нужно написать код для отображения действий.
