Question

I want to implement relationship between Ticket and Flight relationship between the two entities.

A Flight has many tickets which is fine and can be achieved by

`Settickets = new HashSet(0);

@OneToMany
public Set<Ticket> getTickets() {
    return tickets;
}

public void setTickets(Set<Ticket> tickets) {
    this.tickets = tickets;
}`

But how should I implement Ticket has ONLY ONE Flight associated with it ?
I am not sure if Implementing like below would solve the problem. Inside Ticket,java

Flight flight;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name="ticket_id")
public Flight getFlight() {
return flight;
}

public void setFlight(Flight flight) {
    this.flight = flight;
}

`

Any ideas?

Answer 1

You should go this way:

In Flight:

@OneToMany(mappedBy = "flight")
Set<Ticket> tickets;

And in Ticket

@ManyToOne
@JoinColumn(name = "FLIGHT_ID")
Flight flight;
