REST URL с контроллером MVC

0 голосов
/ 28 декабря 2018

Может быть, я что-то упускаю, но не могу пропустить небольшую проблему

Я создаю простое приложение Spring Boot и использую контроллер MVC: @Controller аннотация

Вмой контроллер У меня есть 

@GetMapping("/trainee")
public String trainee(@RequestParam("id") long id, Model model) {

, чтобы ввести этот метод, мне нужно подготовить URL следующим образом: /trainne?id=1, и я бы предпочел /trainee/1

Я знаю, что второй вариант возможен сКонтроллер REST, но я не могу его использовать, потому что он не поддерживает шаблоны.Могу ли я сделать хороший URL-адрес типа REST с контроллером mvc?

Я также добавлю 

@Controller
@RequestMapping("/trainees")
public class TraineeController {

Когда я использую отображение, как @Ken Chan предложил я получаю

Да, вам нужно сделать URL типа REST с контроллером MVC.Вот нижеприведенный код, чтобы сделать REST URL. 

     @Controller
     @RequestMapping("/trainees)
     @ResponseBody
     @RequestMapping(value="/update/{id}", method=RequestMethod.PUT)
      public @ResponseBody  MehodName(@PathVariable ("id") Integer id)
      {
       //write the logic of the method
       }

Вам необходимо использовать @PathVariable аннотацию на входах, чтобы использовать сопоставление URL-адреса 

@Controller
@RequestMapping("/trainees")
public class TraineeController {

    @GetMapping("/trainee/{id}")
    public String trainee(@PathVariable("id") String id, Model model) {
         // Your code here
    }

}

Вы также можете добавить logging.level.org.springframework.web=DEBUG к application.properties, чтобы проверить, какая пружина сопоставления настроенадля вас
