Vertx-js事件总线未从发送方接收数据

Question

我在核心示例下使用了官方github存储库中的vertx-js事件总线示例。

即使它没有从发送者向接收者发送数据。

Sender.js

private LocationManager locationManager;

private Handler handler = new Handler();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps_page);

locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);

 locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 0, new LocationListener() {
        @Override
        public void onLocationChanged(Location location) {

        }

        @Override
        public void onStatusChanged(String provider, int status, Bundle extras) {

        }

        @Override
        public void onProviderEnabled(String provider) {
              handler.postDelayed(runnable,3000);
        }

        @Override
        public void onProviderDisabled(String provider) {

            handler.removeCallbacks(runnable);
        }
    });

      private Runnable runnable = new Runnable() {
    @Override
    public void run() {

      getCurrentLocation();

        Toast.makeText(mapsPage.this, "GETTING LOCATION", Toast.LENGTH_SHORT).show();

        handler.postDelayed(this, 3000);
    }
};

   private void getCurrentLocation() {
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        return;
    }
    Location location = LocationServices.FusedLocationApi.getLastLocation(googleApiClient);
    if (location != null) {
        longitude = location.getLongitude();
        latitude = location.getLatitude();

        moveMap();

        Integer loc = Math.round(location.getAccuracy());
        textings.setText(Integer.toString(loc));

        if(loc <= 100)
    {
        handler.removeCallbacks(runnable);

        Toast.makeText(mapsPage.this, "HANDLER STOPPED", Toast.LENGTH_SHORT).show();
    }

    }
}

//Function to move the map
private void moveMap() {

    LatLng latLng = new LatLng(latitude, longitude);

    mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
    mMap.animateCamera(CameraUpdateFactory.zoomTo(17));
    mMap.addMarker(new MarkerOptions().position(latLng).draggable(false));

}

Reciever.js

var eb = vertx.eventBus();

// Send a message every second

vertx.setPeriodic(1000, function (v) {

  eb.send("ping-address", "ping!", function (reply, reply_err) {
    if (reply_err == null) {
      console.log("Received reply " + reply.body());
    } else {
      console.log("No reply");
    }
  });

});

我使用以下方法运行程序。

vertx run reciever.js -cluster
vertx run sender.js -cluster
