От одного из многих и многих, используя проблему с картстрактом ⇐ JAVA

[Anonymous]

Я пытаюсь использовать Mapstruct для картирования объекта с объектом Buisness.
У меня есть структура слоя в проекте. (DTO, Buisness, Entity)
В этой настройке отображения я игнорирую пользователя /бронирования, чтобы они были «нулевыми». Если я установите его в разные значения, он попадает в бесконечный цикл (Stackoverflow)
мне нужно получить бронирование с информацией о пользователе (пользователь и т. Д.)

Reservations mapFromEntity(ReservationsEntity entity);

}

Example of reservation:
reservation: Reservations(reservationId=29, origin=EWR, destination=LIS, departureDate=2025-02-27T17:40, returnDate=2025-03-01T12:50, airline=TP, price=805.37, currency=EUR, numberOfPassengers=1, createdAt=2025-02-27T04:28:35.877725, user=null)

Как реализовать, может быть, @aftermapping или другое решение для этого?>
