Wie zu vermeiden TransientPropertyValueException

Ich habe Klasse Anagrafica (Konto, in Englisch) und ich muss, aus einem Formular, ID_Tipo_Anagrafica (Account-Typ, in Englisch). Ich habe ein Formular erstellt, das eine Liste von ID_Tipo_Anagrafica bekommen kann, aber ich kann kein endgültiges Objekt erstellen, um es in die Datenbank zu bringen.Wie zu vermeiden TransientPropertyValueException

Es sieht aus wie es eine Entität vom Typ Ruolo zu Ihrer Anagrafica Instanz zugewiesen, aber die Ruolo noch im Übergangszustand (neu). Das heißt, die - wo immer sie herkommt - ist in Ihrem aktuellen Persistenzkontext noch nicht "bekannt". Die Ruolo Eigenschaft auf Anagrafica scheint auch obligatorisch (nicht NULL), so bei Spülzeit Sie unbedingt folgende Ausnahme erhalten:

[...] TransientPropertyValueException: Nicht-Null-Eigenschaft verweist auf einen vorübergehenden Wert [...]

um dies zu lösen, würden Sie entweder die Ruolo speichern, bevor die Anagrafica speichern oder eine Strategie für die transitive Persistenz definieren, auch bekannt als CascadeType. Sie müssen entscheiden, was zu Ihren Anwendungsfällen passt.

Erfahren Sie mehr über Entity states und transitive persistence in der Dokumentation oder besuchen Sie Vlads Anfänger Beratungen über Entity state transitions with JPA and Hibernate und Hibernate Cascade Types.

gelöst von mir selbst. Ich sollte 'anagrafica.ruolo.id' in Wertfeld setzen. Tschüss – Manlio
