How to make an app factory with logger middleware?

[vadim-su]

Before I used to something like this:

fn app_factory() -> App<
    impl ServiceFactory<
        ServiceRequest,
        Config = (),
        Response = ServiceResponse,
        Error = actix_web::Error,
        InitError = (),
    >,
> {
    App::new()
        .configure(users::config)
        .configure(webfinger::config)
}

but when I add .wrap(Logger::new("%a %{User-Agent}i")) compiler ask me to define the next signature

expected struct `ServiceResponse<middleware::logger::StreamLog<BoxBody>>`
found struct `ServiceResponse<BoxBody>`

But middleware::logger::StreamLog in a private mod. How can I bypass this?
