Map multiiple Java pojo fields to one json field with Jackson annotations

Question

I'm trying to map two fields from Java POJO to one json field;

public class Person {
    private String firstName;

    //this two fields should be in separate json property (object)
    private String street;
    private String streetNo;
...
    //getters and setters
}

And I want to get response something like this:

{
    firstName: "Peter",
    address: {
        street: "Square nine",
        streetNumber: "12"
    }
}

You should implement then another POJO Address and add address field to your Person POJO

public class Person {
    private String firstName;

    private Address address = new Address();

...
    //getters and setters
}

// another POJO
public class Address {
    private String street;
    private String streetNo;

    //getters and setters
}
