Wie konfiguriert man Spring mvc 3, um kein "Null" -Objekt in der JSON-Antwort zurückzugeben?

einer Stichprobe von json-Antwort sieht wie folgt aus:

{"publicId":"123","status":null,"partner":null,"description":null}

Wäre es schön, abschneiden, alle null-Objekte in der Antwort. In diesem Fall, die Antwort würde {"publicId":"123"}.

Irgendwelche Ratschläge? Danke!

P. S: ich glaube, ich kann das in Jersey. Auch ich glaube, dass Sie sowohl Jackson als JSON-processer.
