Adding a controller to drive user requests
The link between the persistence layer and the user's view falls on the
TheatreSetupService bean, which will drive requests to the actual services exposed
by our application. Since this bean will be bound to RequestScope and we need to ex-
pose it to our views as well (using @Named ), we can use the convenient @Model annota-
tion for it, which is a sum of the following two attributes:
@Model
public class TheatreSetupService {
@Inject
private FacesContext facesContext;
@Inject
private TicketService ticketService;
@Inject
private List<SeatType> seatTypes;
@Produces [1]
@Named
private SeatType newSeatType;
@PostConstruct
public void initNewSeatType() {
newSeatType = new SeatType();
}
public String createTheatre() {
ticketService.createTheatre(seatTypes);
return "book";
}
public String restart() {
ticketService.doCleanUp();
return "/index"; [4]
}
