How to get current host and port in micronaut?

Question

I'm trying to get current host and port in micronaut application. how do i get it in dynamic manner?

I've tried @Value("{micronaut.server.host}") and @Value("{micronaut.server.port}") but doesn't work.

@Controller("/some/endpoint")
class SomeController {
    @Value("{micronaut.server.host}")
    protected String host;

    @Value("{micronaut.server.port}")
    protected Long port;
}

There are a number of ways to do it. One is to retrieve them from the EmbeddedServer.

import io.micronaut.http.HttpStatus;
import io.micronaut.http.annotation.Controller;
import io.micronaut.http.annotation.Get;
import io.micronaut.runtime.server.EmbeddedServer;

@Controller("/demo")
public class DemoController {

    protected final String host;

    protected final int port;

    public DemoController(EmbeddedServer embeddedServer) {
        host = embeddedServer.getHost();
        port = embeddedServer.getPort();
    }

    @Get("/")
    public HttpStatus index() {
        return HttpStatus.OK;
    }
}
