Hibernate: нет конструктора по умолчанию для внутреннего класса сущности
Я понимаю, что есть много подобных вопросов, но ни один не помог мне в этом.
Я использую инфраструктуру CRUD под названием Tynamo, которая, в свою очередь, опирается на Apache Tapestry и Hibernate. Все это прекрасно работает, за исключением случая, когда я пытаюсь использовать его для CRUD на таблице с составным / составным первичным ключом.
Я решил не идти @EmbeddedId маршрут, так как он, кажется, не работает вообще с рамками. Это, как говорится, я использовал @IdClass метод, который в основном работает; Я думаю, что я один или два кода кода от успеха.
Проблема в том, что когда он начинает использовать отражение для построения объектов, он взрывается и говорит: org.hibernate.InstantiationException: No default constructor for entity: ...хотя для этого внутреннего класса действительно есть открытый пустой конструктор.
При ответе, пожалуйста, избегайте фрагментов кода, используйте полные классы и т. Д., Чтобы другие, посещающие эту ветку, могли получить более полное представление о том, что происходит.
Вы можете увидеть мой класс ниже:

Решение
Под одеялом, TransferExtensionPK на самом деле не имеет конструктора по умолчанию, потому что это внутренний класс. Внутренние классы требуют, чтобы экземпляр их внешнего класса был создан, поэтому компилятор преобразовал ваш конструктор без параметров в конструктор с одним параметром, который принимает экземпляр TransferExtension,
Чтобы решить проблему, сделайте TransferExtensionPK просто вложенный класс (статический), а не внутренний класс:
public static class TransferExtensionPK // etc
