Ignoring Json property if not present in constructor in java

Question

I have a class as show below:-

@Getter
@Setter
@NoArgsConstructor
public class Response extends ResponseMessage {

    @JsonProperty("ResponseDto")
    private myDTo myDto;

    @JsonProperty("revId")
    private Long revisionId;

    @JsonProperty("modelId")
    private Long model;

    public Response(HttpStatus status, String message) {
        super(status, message);
    }

    public Response(HttpStatus status, String message, Long revisionId) {
        super(status, message);
        this.revisionId = revisionId;
    }

    public Response(HttpStatus status, String message, Long revisionId, Long modelId) {
        super(status, message);
        this.revisionId = revisionId;
        this.model = modelId;
    }

    public Response(HttpStatus status, String message, myDTo myDto) {
        super(status, message);
        this.myDto = myDto;
    }
}

Now when i am return the Response class as response as shown below:-

return new Response(HttpStatus.OK,"done",123);

It return the response json as:-

{
"revId":123,
"status":"OK",
"modelId":null,
"message":"done"
}

but the want the response to be depend on the constructor which is being called. which in this case should be :-

{
"revId":123,
"status":"OK",
"message":"done"
}

Any help will be highly appreciated!

you should use @JsonInclude(Include.NON_NULL) for ignore null fields.
