ressort 3 mvc Aucune correspondance trouvée pour la requête HTTP avec l'URI

Question

info d'erreur: Aucun mappage trouvé pour la requête HTTP avec l'URI [/TestSpringWebApp/hello.htm]

Toute aide serait grandement appréciée! J'utilise l'annotation pour mapper la demande au contrôleur. code du contrôleur:

@Controller 
@RequestMapping("/hello.htm") 
public class HelloController {  
    protected final Log logger = LogFactory.getLog(getClass()); 

    public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response)  
      throws ServletException, IOException { 
     String now = (new Date()).toString(); 

     logger.info("Returning hello view with " + now); 

     return new ModelAndView("hello", "now", now);  
    }  
} 

Dispatcher-servlet.xml comme suit:

<?xml version="1.0" encoding="UTF-8"?>

    <!--

    for the index controller we are using ParameterizableViewController, so we must 
    define an explicit mapping for it.

Answer 1

Vous devez ajouter @RequestMapping t o la méthode, pas à la classe. Si vous l'ajoutez à la classe, il sera appliqué en tant que préfixe à tous les mappages de méthodes de cette classe, mais vous devrez également mapper les méthodes de la classe.

Answer 2

Vous devez également ajouter

<mvc:annotation-driven />

à votre fichier Dispatcher-servlet.xml.

Answer 3

Vous pouvez avoir @RequestMapping pour la classe aussi, mais chaque méthode doit aussi avoir sa propre « @RequestMapping » S'il vous plaît voir exemple ci-dessous.

@Controller 
@RequestMapping("/appointments") 
public class AppointmentsController { 

    private final AppointmentBook appointmentBook; 

    @Autowired 
    public AppointmentsController(AppointmentBook appointmentBook) { 
     this.appointmentBook = appointmentBook; 
    } 

    @RequestMapping(method = RequestMethod.GET) 
    public Map<String, Appointment> get() { 
     return appointmentBook.getAppointmentsForToday(); 
    } 

    @RequestMapping(value="/{day}", method = RequestMethod.GET) 
    public Map<String, Appointment> getForDay(@PathVariable @DateTimeFormat(iso=ISO.DATE) Date day, Model model) { 
     return appointmentBook.getAppointmentsForDay(day); 
    } 

    @RequestMapping(value="/new", method = RequestMethod.GET) 
    public AppointmentForm getNewForm() { 
     return new AppointmentForm(); 
    } 

    @RequestMapping(method = RequestMethod.POST) 
    public String add(@Valid AppointmentForm appointment, BindingResult result) { 
     if (result.hasErrors()) { 
      return "appointments/new"; 
     } 
     appointmentBook.addAppointment(appointment); 
     return "redirect:/appointments"; 
    } 
}
