Ich versuche, die Partei der Klasse zu, aber es gibt mir Spalte ‚PARTY_PTY_ID‘ Fehler kann nicht null sein

Ich bin mit JPA mit Hibernate

partyRepository.save (Partei);

ich auf diese Weise

DeviceRegistration deviceRegistration = new DeviceRegistration(); 
deviceRegistration.setStatus("ENABLE"); 
deviceRegistration.setDeviceId(party.getDeviceRegistration().get(0).getDevic‌​eId()); 
deviceRegistration.setPNSDeviceId(""); 
Party userDetails = (Party) partyRepository.save(party); 

Answer 1

nach dem Fehler PARTY_PTY_ID ist null.and diese Spalte in der DeviceRegistration Klasse machte, da Sie deviceRegistration Eigenschaft mit CascadeType.ALL kommentierten haben. deviceRegistration Tabelle wird auch aktualisiert, wenn Sie versuchen, Party in der Datenbank zu speichern.

@OneToMany(cascade=CascadeType.ALL,mappedBy = "party") 
private List<DeviceRegistration> deviceRegistration; 

so müssen Sie mit diesem Ansatz gehen, um beide richtig zu speichern.

Party partyOb; 
DeviceRegistration deviceregistrationob; 

deviceregistrationob.setParty(partyOb); 
partyOb.setDeviceRegistration(deviceregistrationob); 

Sie haben die party Objekt zum DeviceRegistration Objekt hinzuzufügen. und fügen Sie dann DeviceRegistration Objekt zum partyObject

bearbeitet: -

DeviceRegistration deviceRegistration = new DeviceRegistration();  
deviceRegistration.setStatus("ENABLE"); 
deviceRegistration.setPNSDeviceId(""); 

//this part was missing in your code 
List<DeviceRegistration> deviceRegistrationList = new ArrayList(); //creating a list of DeviceRegistration 
deviceRegistration.setParty(party); //adding a party to the device 
deviceRegistrationList.add(deviceRegistration); //adding device to the list 
party.setDeviceRegistration(deviceRegistrationList); //adding device list to the party. 
//**end 
deviceRegistration.setDeviceId(party.getDeviceRegistration().get(0).getDevic‌eId());//this line should be called after adding device list to the party. otherwise you'll get null pointer exception. 
Party userDetails = (Party) partyRepository.save(party);
