Creating common data model for greenDao and retrofit

I have json reponse from a web service which is like this

"address": {

I am using Retrofit and greenDao for my project . For both we need a data model . For retrofit only , my data model look like this

public class Example {

private Integer id;
private String name;
private Address address;

public Example() {

public Example(Integer id, String name, Address address) { = id; = name;
this.address = address;

public Integer getId() {
return id;

public void setId(Integer id) { = id;

public String getName() {
return name;

public void setName(String name) { = name;

public Address getAddress() {
return address;

public void setAddress(Address address) {
this.address = address;


public class Address {

private String streetName;
private String city;

public Address() {

public Address(String streetName, String city) {
this.streetName = streetName; = city;

public String getStreetName() {
return streetName;

public void setStreetName(String streetName) {
this.streetName = streetName;

public String getCity() {
return city;

public void setCity(String city) { = city;


Which can be used for
, but
has a generator , which also make data model . How can I generate Datamodel from greenDao generator project , which can be used for both retrofit and greenDao

Thanks in advance


Here is how a generator should look like:

    Schema schema = new Schema(1, <>);

    Entity model = schema.addEntity("Model");

    Entity address = schema.addEntity("Address");
    Property addressIdProperty = address.addIdProperty().getProperty();

    model.addToOne(address, addressIdProperty).setName("address");

    DaoGenerator generator = new DaoGenerator();
    generator.generateAll(schema, "./app/src/main/java");

As you can see, the Model class contains a reference to address, by adding one-to-one relation and naming it "address".

This way any json parser like GSON can parse your objects and put them in database.
