Verwenden von Composite-Schlüssel mit JPA

Question

Lernen mit Spring und all seinen Werkzeugen unterwegs. Nicht sicher, wie man den PK anstelle des Strings benutzt. tickets = repository.findOne (tk.getSerial()); Will Primärschlüssel aber nicht den richtigen Weg finden?

Answer 1

em.find nimmt in einer Instanz der IdClass. In diesem Fall müssen Sie eine Instanz von TicketsPK übergeben, keine Komponente davon.
