Swagger (Springfox) only finding Models used in Controller @RequestBody (Spring Boot)

Well, what I mean is that I'm trying to use Springfox' implementation in my Spring Boot REST API for documentation and testing in java, and that the only Models autodetected by Swagger are the ones used as parameters in the Controller methods.

For example:

@PostMapping("/signin")
    @ApiOperation
    public String login(
            @ApiParam(value = "The login credentials DTO (username and password)", required = true) 
            @RequestBody
            @Valid LoginCredentialsDTO loginCredentialsDTO) {
        return userService.login(loginCredentialsDTO);
    

It detects the Model "LoginCredentialsDTO" because it was used here in the controller method.

Since I only use DTOs in my controller, it's not detecting my main model (User). I don't want to have to make a dummy method just for Swagger to be able to detect all my models.

It's possible that I should ask the Springfox community (if there is one) about this instead, my mistake if I asked the wrong people.
