REST url with mvc controller

Maybe I'm missing something but I can not pass a small issue

I'm building a simple Spring Boot app and I am using MVC Controller: @Controller annotation

In my controller I have 

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

to enter that method I need to prepare url like this: /trainne?id=1 and I would prefer /trainee/1

I know that the second option is possible with REST Controller but I can not use it cause it does not support templates. Can I make a nice REST type url with mvc controller?

I will also add

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

When I use mapping like @Ken Chan suggested I receive

Yes you need to make the REST type url with mvc controller. here is the bellow code to make the 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
       }

You need to use @PathVariable annotation on inputs to use the url patter matching

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

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

}

You can also add logging.level.org.springframework.web=DEBUG to your application.properties in order to check what mappings spring has set up for you
