javax.servlet.ServletException: Konnte die Ansicht mit dem Namen 'hotels/booking/enterBookingDetails' im Servlet mit dem Namen 'travel' nicht auflösen

Question

Ich habe versucht, einige ähnliche Fragen zu StackOverflow zu lesen, konnte aber nicht wirklich verstehen! Dies ist meine erste Spring-Anwendung, daher entschuldige ich mich für eine möglicherweise doppelte Frage. Jede Hilfe würde wirklich geschätzt werden.

ich die folgende Fehlermeldung erhalten, wenn ich navigieren zu enterDetails Seite: -

Exception thrown by application class 'org.springframework.web.servlet.DispatcherServlet.render:1029'

Hier ist der Controller: -

@RequestMapping(value = "hotels/booking", method = RequestMethod.GET) 
public String bookingDetails(@RequestParam Long hotelId, Model model) {  
    Booking booking = bookingService.createBooking(hotelId,"keith"); 
    model.addAttribute(booking); 
    return "hotels/booking/enterBookingDetails"; 
}

Answer 1

Ich bin neu hier, aber ich habe an einigen Frühlings-MVC-Projekten gearbeitet. So hoffe ich, zur Lösung Ihres Problems beizutragen.

würde ich Ihren Controller ändern, um mit dem Modeland Objekt zu arbeiten, so dass Sie Folgendes tun:

@RequestMapping(value = "hotels/booking", method = RequestMethod.GET) 
    public ModelAndView bookingDetails(@RequestParameter Long hotelId) { 

    ModelAndView model = new ModelAndView("enterBookingDetails"); 
    Booking booking = bookingService.createBooking(hotelId,"keith"); 
    model.addObject("booking", booking); 
    return model; 
}
