"Distachiertes Unternehmen, das an Bestehen gebracht wurde", unmittelbar nach dem Sparen ⇐ Java

[Guest]

Ich habe die folgende Methode, die eine org.springframework.dao.invaliddataAccessapiusageException: abgenommene Entität an persist: com.domain.Pasger auf dem vehicleRepository.Saveall Call werfen. Ich verstehe nicht, warum dies geschieht, da der Passagier noch ein paar Zeilen bestehen wird, und sollte es daher nicht noch eine beigefügte Einheit sein? Ich bin besonders verwirrt, weil die Eigenschaft speichern und in Passagier in Ordnung funktioniert. ist:

Code: Select all

@OneToOne(cascade = CascadeType.PERSIST)
@JoinColumn(name = "passenger_id", updatable = false)
@JsonManagedReference(value = "vehicle-passenger")
private Passenger passenger;
< /code>
Und hier ist die Methode zur Einrichtung der Unit -Test: < /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
));
}
