@GeneratedValue(strategy=GenerationType.IDENTITY)

}
As you can see, the
Seat
entity has the corresponding
@ManyToOne [1]
annotation,
which naturally complements the
@OneToMany
relationship. The
@JoinColumn [2]
notifies the JPA engine that the
seatType
field is mapped through the foreign key of the
database's seat ID.
