Retrofit 2 come ottenere la risposta da oggetti JSON nidificati (Android)

Question

questa è la mia prima risposta JSON e ho ottenuto il token

{ 
"token": "I0ZmEifQ.CdbGWjkIYnuO29uJokCIGn8kXFbLbVp3gnlsEszagno" 
} 

classe POJO

public class TokenReceiver { 
    private String token; 

    public String getToken() { 
     return token; 
    } 
} 

quanto sopra ha funzionato bene, ma come per ottenere la risposta per il seguito

{ 
    "user": { 
    "id": 1, 
    "first_name": "Super", 
    "last_name": "Admin", 
    "email": "abc@sad.sdf", 
    "mobile_no": 2147483647, 
    "created_at": "2016-01-21 00:00:00", 
    "updated_at": "2016-01-21 00:00:00", 
    "user_role_id": 1 
    } 
} 

il codice di stato 200 (OK) , ma il dato non è g reparativi attaccato al POJO

public class User { 

    @SerializedName("id") 
    @Expose 
    private int id; 

    @SerializedName("first_name") 
    @Expose 
    private String first_name; 

    @SerializedName("last_name") 
    @Expose 
    private String last_name; 

    @SerializedName("email") 
    @Expose 
    private String email; 

    @SerializedName("mobile_no") 
    @Expose 
    private String mobile_no; 

    @SerializedName("created_at") 
    @Expose 
    private String created_at; 

    @SerializedName("updated_at") 
    @Expose 
    private String updated_at; 

    @SerializedName("user_role_id") 
    @Expose 
    private int user_role_id; 
} 

grazie in anticipo
