Generate OpenAPI spec for vertx project

I want to generate an OpenAPI spec for my vertx project. So I have a simple vertx server as follows which just returns me a json object:

package server;

import io.vertx.core.AbstractVerticle;
import io.vertx.core.http.HttpServer;
import io.vertx.core.http.HttpServerRequest;
import io.vertx.core.http.HttpServerResponse;
import io.vertx.core.json.JsonArray;
import io.vertx.core.json.JsonObject;
import io.vertx.ext.web.Router;
import io.vertx.ext.web.RoutingContext;
import io.vertx.ext.web.handler.BodyHandler;

public class Server extends AbstractVerticle {

  @Override
  public void start() throws Exception {
    HttpServer server = vertx.createHttpServer();
    Router router = Router.router(vertx);
    router.route("/v0.2.2/*").handler(this::responseSetUp);
    router.get("/v0.2.2/location").handler(this::getLocation);
    server.requestHandler(router::accept).listen(8004);
  }

  public void responseSetUp(RoutingContext context) {
    HttpServerResponse response = context.response();
    response.putHeader("Access-Control-Allow-Origin", "*")
        .putHeader("Access-Control-Allow-Methods", "GET, POST, PUT , DELETE, OPTIONS")
        .putHeader("Access-Control-Allow-Headers", "Content-Type,cache-control, x-requested-with")
        .putHeader("Access-Control-Max-Age", "86400");
    context.next();
  }

  public void getLocation(RoutingContext context) {
    JsonObject location = new JsonObject();
    location.put("city", "Bangalore");
    location.put("country", "India");
    location.put("pin", 560095);
    HttpServerResponse response = context.response();
    response.putHeader("content-type", "application/json");
    response.setChunked(true);
    response.write(location.toString());
    response.end();
  }
}

I just want to generate an OpenAPI spec for this route. I am new to Swagger and so far while googling, I could see tutorials for RestEasy, Mule, Jersey1,Jersey2, Spring but not for vertx.

Can anyone please help me out or any pointers?

Sorry, if the question is naive.

With Vert.x 3.5.0 there's a new package called Vert.x Web API Contract that helps you generate the Router and the Validation handlers for your request. You can also generate a skeleton of your project with slush-vertx, a command line tool that helps you scaffolding your project
