What is the best way to pass a single parameter to a JSON Post?

Question

Java

Should I create a POJO with a single field and get it via @RequestBody or is it better to directly specify @RequestBody with Integer?

Like this for example

@PostMapping
    @ResponseStatus(HttpStatus.CREATED)
    public void create(@AuthenticationPrincipal AuthenticatedUser authenticatedUser,
                       @RequestBody Integer clientId) {
        clientService.add(authenticatedUser.getUser(), clientId);

}

Answer 1

If in the future it may be necessary to expand the set of transmitted fields, then using now POJO with one field, then you will have to rewrite less.

Answer 2

The real practice in production is to have dto-classes under web controllers that are passed in the request parameter.
