Hallo all Is it possible to persist a generic field?

I have this property on an Entity class ... private T payload; ...

T extends EventMessagePayload

and public interface StringPayload extends EventMessagePayload{ String getPayload(); }

In my application i persist the field only when is of String type and during the save operation all works great.

When I read the object instead JPA try to create a String object but instead is a StringPaylod. Is there a way to intercept the creation and handle the object marshalling?

Kind regards Massimo
