Spring Boot: Is it possible to consume @RequestParam's as json?

Question

I have following rest endpoint in spring boot application:

    @RequestMapping(method = RequestMethod.POST, value = "/sign-in")
    public Client signIn(@RequestParam String username, @RequestParam String password, HttpServletRequest request) {
        Client client = authService.signIn(username, password);
        return client;
    }

I want accept data as application/json.

Is it possible to do this WITHOUT creating class for this like this?:

public class LoginModel {
   private String username;
   private String password;
   ...
}

Also, without argument of type Map in signIn method

I need to accept application/json with this signature:

public Client signIn(@RequestParam String username, @RequestParam String password)

Is it possible?

Answer 1

No. I don't think it's possible.

You need to create the intermediary Login object.

@RequestParam mandates you have a request param.
