Process finished with exit code 1 when stopping Embedded Undertow

Question

In my application I start embedded Undertow in program main method. In all tutorials stop method is not used. If I run appliction from terminal or from IntelliJ and stop it (CTRL+C or stop icon) I see

Process finished with exit code 1

I tried adding

Runtime.getRuntime().addShutdownHook(new Thread(undertow::stop));

but result is the same.

Where should I call stop method?

Answer 1

Here is a sample builder api which can be altered(just a sample) to stop after performing a console logging as:

public class HelloWorldServer {

    public static void main(final String[] args) {
        Undertow server = Undertow.builder()                                                    //Undertow builder
                .addListener(8080, "localhost")                                                 //Listener binding
                .setHandler(new HttpHandler() {                                                 //Default Handler
                    @Override
                    public void handleRequest(final HttpServerExchange exchange) throws Exception {
                        exchange.getResponseHeaders().put(Headers.CONTENT_TYPE, "text/plain");  //Response Headers
                        exchange.getResponseSender().send("Hello World");                       //Response Sender
                    }
                }).build();
        server.start();
        System.out.println("I did some work for you..Rest is to dig deeper!");
        server.stop();
    }

}
