GSON - Custom serializer in specific case

Question

I have this schema :

public class Student {
       public String name;
       public School school;
}

public class School {
       public int id;
       pub         


        

Answer 1

You can write a custom serializer something like this:

public class StudentAdapter implements JsonSerializer {

 @Override
 public JsonElement serialize(Student src, Type typeOfSrc,
            JsonSerializationContext context) {

        JsonObject obj = new JsonObject();
        obj.addProperty("name", src.name);
        obj.addProperty("school", src.school.id);

        return obj;
    }
}
