I have Java bean:

public class User {
    private int id;
    private String name;
    private Address address;
    private List<String> favoriteBooks;
    private List<String> favoriteFilms;

    //getters and setter
}

I want convert instance of User class into JSON format, but selecting only three fields: id, name, favoriteBooks. I search some solution like 

String[] fieldNames = { "id", "name", "favoriteBooks" };
JsonObject jo = new JsonObject(user, fieldNames);

How can I do it?

EDIT I found the answer here https://stackoverflow.com/a/13792700 with using Jackson library

You can try GSON library that allows you to convert beans to json and vice versa.

That's possible in Jersey 2 (MOXy or Jackson 2). For queries like this,

people/1234?select=familyName,givenName

it would return this json:

{
    "familyName": "Dowd",
    "givenName": "Andrew"
}

Using jakson library you can mark properties with @JsonIgnore annotation to exclude it from converting.
