how to convert static variables in class to json

Question

Hi I have a class Constants that contain only static variables.public class Constants

public class Constant
{
    public static class A
    {
        public static class B
        {
            public static final int  COLUMN = 0;
            public static final String  TYPE =  ColumnType.INPUT;
        }
    }
}

Is there a way to convert this class to JSON ?

I was using gson, but apparently it ignores static variables. So how can I do it ?
Thanks.

Answer 1

The accepted answer is correct. For clarity here is a working example. You can use the GsonBuilder class with the method excludeFieldsWithModifiers.

    GsonBuilder gsonBuilder  = new GsonBuilder();
    // Allowing the serialization of static fields
    gsonBuilder.excludeFieldsWithModifiers(java.lang.reflect.Modifier.TRANSIENT);
    // Creates a Gson instance based on the current configuration
    Gson gson = gsonBuilder.create();
    String json = gson.toJson(objectToSerialize);
    System.out.println(json);

Answer 2

You can configure which field modifiers GSON ignores with this method on the GsonBuilder class.
