Feature request: Skip only objects which are null during serialization #288
Description
I've got a Java object containing many nested objects. When I serialize this object the response get large. There currently is a "omitDefaults" parameter, but this also removes booleans which are false and ints which are 0. In my scenario I can't remove these.
As far as I can see from the documentation, I'm using version 2.0.2, the way to remove only null objects is currently to write a serializer manually. For nested object graphs this would be very tedious and potentially error prone.
It would therefore be nice to have a way to configure whether you want null objects included during serialization, or not.
E.g: @CompiledJson(skipNulls = true) and also maybe @JsonAttribute(skipNull = true) for finer control.
