Hibernate: java.lang.ClassCastException bei speichern

Question

Ich habe ein seltsames Problem mit HIBERNATE heute, gibt es java.lang.ClassCastException, wenn ich versuche, ein Objekt in der Datenbank zu speichern. Hier

ist der Stack-Trace des Fehlers:

Wir Frühling verwenden und hibernate, alles in Ordnung arbeitet ich verstehe nicht, was das Problem sein könnte.

Answer 1

Das Serializable-Objekt, das von der Methode save() der Hibernate-Sitzung zurückgegeben wird, ist die ID ("generated identifier") des Objekts, nicht das Objekt selbst. Es ist also die Umwandlung in (T) in der Speichermethode, die fehlschlägt. Ändern Sie entweder den Rückgabetyp oder geben Sie stattdessen das gespeicherte Objekt zurück.
