Hibernate One to One relationship

Question

suppose we have a class called LatLng:

public class LatLng {

    private long id;
    private double latitude;
    private double longitude;

    //setters & getters

}

as you can see in the picture below:

we have a one-to-one relationship between PoliceStation and LatLng

and one-to-one relationship between Hotel and LatLng

and so on...

how can we create such a relationship in hibernate? (both annotation and xml-mapping)

Answer 1

What you need is a bidirectional one-to-one association between your entities.

Check these links:

Hibernate - bidirectional @OneToOne

Hibernate bidirectional using mapping files.

Follow the links and try to create your entities.
