Spring Boot @onetomany und @Manytoone retten keinen ausländischen Schlüssel ⇐ Java

[Anonymous]

Ich verwende @onetomany und @Manytoone im Spring -Boot und wenn ich versuche, in der Datenbank ( postgressql ) zu speichern, die Fremdschlüssel ist nicht gerettet. Ich habe versucht, alle beschriebenen Anweisungen und Einstellungen zu befolgen, aber wenn ich die DB überprüfe, haben alle gespeicherten Elemente immer den fremden Schlüssel null < /p>

Code: Select all
