«Отличное сущность принята на стойкость» сразу после спасения ⇐ JAVA

[Anonymous]

У меня есть следующий метод, который бросает org.springframework.dao.invaliddataaccessapiusageexception: отдельная сущность, передаваемая в течение постоянного: com.domain.passenger на eforciclerepository.saveall call. Я не понимаю, почему это происходит, так как пассажир сохраняется всего за несколько строк, и, следовательно, разве это не должно быть прикрепленным сущностью? Я особенно сбит с толку, потому что свойство Сохранить и передавать это в пассажир работает очень хорошо. :
@OneToOne(cascade = CascadeType.PERSIST)
@JoinColumn(name = "passenger_id", updatable = false)
@JsonManagedReference(value = "vehicle-passenger")
private Passenger passenger;
< /code>
А вот метод настроек модульного теста: < /p>
@DataJpaTest
@Transactional(propagation = NOT_SUPPORTED)
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
class Tests {

@BeforeAll
void setup() {

Vehicle veh1 = build.fromFile(Vehicle.class, "json/Vehicle");
Vehicle veh2 = build.fromFile(Vehicle.class, "json/Vehicle");
Vehicle veh3 = build.fromFile(Vehicle.class, "json/Vehicle");
Vehicle veh4 = build.fromFile(Vehicle.class, "json/Vehicle");

// persist a property to use
Property property = build.fromFile(Property.class, "json/Property");
property.setPropertyId(1L);
propertyRepository.save(property);

Passenger passenger1 = build.fromFile(Passenger.class, "json/Passenger");
Passenger passenger2 = build.fromFile(Passenger.class, "json/Passenger");

// add test properties to passengers
passenger1.setProperty(property);
passenger2.setProperty(property);
passenger1 = passengerRepository.save(passenger1);
passenger2 = passengerRepository.save(passenger2);

// add test passengers to vehicles
veh1.setPassenger(passenger1);
veh2.setPassenger(passenger2);

vehicleRepository.saveAll(List.of(
veh1,
veh2,
veh3,
veh4
));
}
