Log (record) unmatched routes

Add a default service and route (This example uses tracing to do the recording)

default_service(web::route().to(not_found)); // Added into config

#[tracing::instrument]
pub async fn not_found(req: HttpRequest) -> actix_web::Result<HttpResponse> {
    error!("Failed to match route");
    Ok(HttpResponse::NotFound().body("404 - Not found\n"))
}

Graceful shutdown

There are multiple references I found and the appropriate one depends on your use case. I’m collecting them here because I don’t want to have to search for them again. I recommend also checking out Tokio Cancellation Tokens as well as applicable to your use case.

Resources:

• Official example of shutdown - It shows how to shutdown from an endpoint
• Example Response to issue - Shows how to shutdown if there is another task running in parallel to actix_web. Both tasks get shutdown gracefully. To shutdown the second task I’d recommend using Tokio Cancellation Tokens instead.
• Official Documentation website - Explains the default behaviour
