WebFlux.fn вообще не маршрутизирует

Я пытаюсь использовать WebFlux.fn.

Я написал веб-контроллер, и он работает. 

@RestController
@RequestMapping(path = "/api/v1/employees")
public class EmployeesController {

    @RequestMapping(method = GET, path = "/{id:.+}", produces = APPLICATION_JSON_VALUE)
    public ResponseEntity<Employee> read(
            @PathVariable(name = "id) String id) {
    }

    @ResponseStatus(NO_CONTENT)
    @RequestMapping(method = PUT, path = "/{id:.+}", consumes = APPLICATION_JSON_VALUE)
    public void updated(@PathVariable(name = "id") String id,
                        @RequestBody Employee entity) {
    }

    @ResponseStatus(NO_CONTENT)
    @RequestMapping(method = DELETE, path = "/{id:.+}")
    public void delete(@PathVariable(name = "id") String id) {
    }
}

И я также написал Reactive Web controller, и он тоже работает. 

@RestController
@RequestMapping(path = "/api/v1/employees/reactive")
public class EmployeesReactiveController {

    @RequestMapping(method = GET, path = "/{id:.+"}, produces = APPLICATION_JSON_VALUE)
    public Mono<Employee> read(
            @PathVariable(name = "id") String id) {
    }

    @ResponseStatus(NO_CONTENT)
    @RequestMapping(method = PUT, path = "/{id:.+}", consumes = APPLICATION_JSON_VALUE)
    public Mono<Boolean> updated(
            @PathVariable(name = PATH_NAME_EMPLOYEE_ID) String id,
            @RequestBody Employee entity) {
    }

    @ResponseStatus(NO_CONTENT)
    @RequestMapping(method = DELETE, path = "/{id:.+}")
    public Mono<Long> delete(@PathVariable(name = "id") String id) {
    }
}

И я застрял с версией WebFlux.fn. 

@Configuration
public class EmployeesReactiveFnConfig {

    @Bean
    public RouterFunction<ServerResponse> employeesRouterFunction(
            EmployeesReactiveFnHandler handler) {
        return route(GET("/api/v1/employees/reactive/fn/{id:.+}"), handler::read);
    }
}

@Component
public class EmployeesReactiveFnHandler {

    public Mono<ServerResponse> read(@NotBlank String id) {
    }

    public Mono<ServerResponse> read(ServerRequest request) {
        return read(request.pathVariable("id"));
    }
}

Кажется, что эти два класса признаны Spring. 

...DefaultListableBeanFactory - Creating shared instance of singleton bean 'employeesReactiveFnConfig'
...DefaultListableBeanFactory - Creating shared instance of singleton bean 'employeesReactiveFnHandler'

Всякий раз, когда я пытался, я получал это.

Ваше приложение не является приложением WebFlux - зависимость HATEOAS переносит Spring MVC транзитивно.

Вы можете удалить эту зависимость, если она не используется (Spring HATOAS также поддерживает WebFlux в последней версии, но автоконфигурация еще не завершена ). Вы также можете принудительно настроить тип веб-приложения в Spring Boot с помощью свойства конфигурации spring.main.web-application-type.
