Answer 1

Your mapping is created correctly. The problem is more likely to come from the Jackson JSON serializer. You should try adding this annotation to your date fields: @JsonFormat (shape = JsonFormat.Shape.STRING, pattern ="yyyy-MM-dd'T'HH:mm:ss.SSSZZ").

There are also some alternative solutions that might better suit your case (i.e. creating a CustomDateSerializer, etc).
