    We can use the primary key generation strategy of type

    GenerationType.AUTO to auto-generate primary key while

    persisting an object in Hibernate.

    Egg.

    @Id

    @GeneratedValue(strategy=GenerationType.AUTO)

    private int id;

    We can leave it null/0 while persisting and Hibernate automatically

    generates a primary key for us.

    Sometimes, AUTO strategy refers to a SEQUENCE instead of an

    IDENTITY
