Gson ignores my fields while converting

Question

I created a model:

public class UserRequest extends DefaultRequest {
    public String username;
    public String password;
    public String id;

    public Us         


        

Answer 1

Not too familiar with Gson, but I don't think Gson would write null values to an json file. If you initialize the id like:

String id = "";

you may get an empty string in there. But you will not get a null value into a .xml file.
