REST url with mvc controller

Question

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

What 's wrong with this : @GetMapping(value = " /trainee/{id}" and public String trainee(@ PathVariable("id") long id, Model model) ? — Ken Chan

@KenChan I've updated my post. I don't want to say that something is wrong with your solution but it just doesn not work. I've already tried it (I'm sorry I've shoudl mention that) — Fixus

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

I've aready tried this and it is not working. I've posted the debug in the update of my post. As for me it can not find the pattern

Fixus Over a year ago

hmm suddenly it started to work o.O I don't get it. I'll run few more tests

Ben Over a year ago

@Fixus perhaps you haven't cleaned or rebuilt your project, and just ran it with the old endpoint mapping?

Ben Over a year ago

@Fixus It's also worth noting that with the debug flag all the registered endpoints should be outputted during the initialization of spring application

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
       }
