Spring Data + Mongo list nested complex type using id as attribute in mongo

How can I work with complex types in Spring Data + Mongo?

Like:

class Person {

    @Id
    String id;
    String name;
    //What can I do?
    Address address
    //OR
    String adressId;
}

How can I build this object for server side use?

I want to use adressId, but I don't know how to proceed when I need to use the address within some method.

For example:

void doWithPerson(Person person){

    System.out.println(person.getAdress());//this doesn't exist with adressId
}

Edit:

I want the mongo object as:

{
  id: 1
  name: 'Test'
  addressId: 1//not the complext object
}

and in addressCollection:

{
  id: 1
  address: 'Some info'
}

You can use @DBRef annotation to store reference of another object into your class object, e.g.:

@DBRef(lazy = true)
Address address;

This way, you can find the Person with particular address id. You can also retrieve Address objects independently by using mongo repository for Address class.

Here is the documentation.
