Following the tutorial on Jersey's user guide, I created a small jax-rs based REST web application. This is the main class that starts the server.
public class Main {
// Base URI the Grizzly HTTP server will listen on
public static final String BASE_URI = "http://localhost:8080/myapp/";
/**
* Starts Grizzly HTTP server exposing JAX-RS resources defined in this application.
*
* @return Grizzly HTTP server.
*/
public static HttpServer startServer() {
// create a resource config that scans for JAX-RS resources and providers
// in com.example package
final ResourceConfig rc = new ResourceConfig().packages("com.example");
// create and start a new instance of grizzly http server
// exposing the Jersey application at BASE_URI
return GrizzlyHttpServerFactory.createHttpServer(URI.create(BASE_URI), rc);
}
/**
* Main method.
*
* @param args
* @throws IOException
*/
public static void main(String[] args) throws IOException {
final HttpServer server = startServer();
System.out.println(String.format("Jersey app started with WADL available at "
+ "%sapplication.wadl\nHit enter to stop it...", BASE_URI));
System.in.read();
server.shutdownNow();
}
}
Resource method handler for GET request:
@Path("myresource")
public class MyResource {
/**
* Method handling HTTP GET requests. The returned object will be sent
* to the client as "text/plain" media type.
*
* @return String that will be returned as a text/plain response.
*/
@GET
@Produces(MediaType.TEXT_PLAIN)
public String getIt() {
return "Got it!";
}
}
when I run the server, I get this on the console:
"C:\Program Files\Java\jdk1.8.0_171\bin\java.exe" ...

INFO: Started listener bound to [localhost:8080]
Jersey app started with WADL available at
http://localhost:8080/myapp/application.wadl
Hit enter to stop it...
Sep 10, 2018 11:51:55 AM org.glassfish.grizzly.http.server.HttpServer start
INFO: [HttpServer] Started.
When I send a GET request via Postman to http://localhost:8080/myapp/myresource, it gives me a status 200 OK with "Got it!" as a response body, but nothing gets logged in the server console.
It might be a very basic question, but how can I implement it so that every time I send an HTTP request to the grizzly server, the requests and responses get logged on the console? I'd really appreciate any sort of help.
