控制器 RequestMapping

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

//your handlers here, for example:

@RequestMapping(path = "/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";
}

}

@RequestMapping 註釋是用於在 @Controller 類中標記 HTTP 處理程式（應用程式的 HTTP 訪問點）的註釋
