SpringMVC URL传参方式

1. ModalAndView

   @Controller
   public class HelloWorldController {
   
       @RequestMapping("/helloWorld")
       public ModelAndView helloWorld() {
           ModelAndView mav = new ModelAndView();
           mav.setViewName("helloWorld");//viewName 视图名称
           mav.addObject("message", "Hello World!");// 往视图传递对象
           return mav;
       }
   }

2. 在Class级别这是@RequestMapping

   @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";
       }
   }

3. @PathVirable

   @RequestMapping(value="/owners/{ownerId}", method=RequestMethod.GET)
   public String findOwner(@PathVariable String ownerId, Model model) {
     Owner owner = ownerService.findOwner(ownerId);  
     model.addAttribute("owner", owner);  
     return "displayOwner"; 
   }
   
   
   @RequestMapping(value="/owners/{ownerId}", method=RequestMethod.GET)
   public String findOwner(@PathVariable("ownerId") String ownerId, Model model) {
     // implementation omitted
   }
