How to exclude a field from @JsonInclude(JsonInclude.Include.NON_NULL)

I have annotated a POJO with @JsonInclude(JsonInclude.Include.NON_NULL) to exclude all null fields while serialization/deserialization. But now I need to exclude one of the fields from this behaviour. ie - I want to send over the value of a field as null if it has a null value. There is some update in legacy code which has put me in this situation.

How can i achieve this?

Edit:

Would using a JSONSerialize(include=CustomSerializer.class) give higher precedence to the CustomSerializer?

Use @JsonInclude(Include.ALWAYS) annotation on your field. This will override @JsonInclude(Include.NON_NULL) on the class level.
