Весной mvc приложение по умолчанию, которое работает, но в приложении webflux есть нет параметров запроса из формы ввода, когда

Я делаю пост-запрос

registration.ftl:

<form action="/registration" method="post">
    <div class="form-group">
        <label class="col-sm-2 col-form-label"> User Name : </label>
        <div class="col-sm-6">
            <input type="text" id="username" name="username" class="form-control" placeholder="User Name"/>
        </div>
    </div>

    <div class="form-group">
        <label class="col-sm-2 col-form-label"> Password : </label>
        <div class="col-sm-6">
            <input  type="password" id="password" name="password" class="form-control" placeholder="Password"/>
        </div>
    </div>

    <input type="hidden" name="_csrf" value="${_csrf.getToken()}"/>

    <div class="form-group">
        <div class="col-sm-20">
            <button class="btn btn-primary" type="submit">Sign In</button>
        </div>
    </div>
</form>

Обработчики:

public Mono<ServerResponse> registrationPost(ServerRequest serverRequest){
    Set<String> stringSet = serverRequest.queryParams().keySet();
    for(String s:stringSet){
        logger.info(s+": "+serverRequest.queryParams().get(s));
    }
    String username = (String) serverRequest.queryParam("username").get();
    String password = (String) serverRequest.queryParam("password").get();
    User user = new User();
    user.setUser_avatar("default.jpg");
    user.setUsername(username);
    user.setPassword(passwordEncoder.encode(password));
    Mono<User> userFromDb = userService.findByUserName(user.getUsername());
    AtomicBoolean atomicBoolean = new AtomicBoolean(false);
    userFromDb.subscribe(u->{
        if(u!=null) atomicBoolean.set(true);
    });
    if(atomicBoolean.get()){
        logger.info("user from db exists");
        return ServerResponse.badRequest().build();
    } else {
        Mono<User> save = userService.save(user);
        save.subscribe(u->{
            logger.info("user successfully created");
        });
        return ServerResponse.temporaryRedirect(URI.create("/login")).build();
    }
