JavaFX如何使用Image和ImageView从我的系统打开和映像

Question

我正在尝试使用JavaFX的Image和ImageView类显示图像，但它不起作用。

try {
  String workingDir = System.getProperty("user.dir");
  final File f = new File(workingDir, "src/chk.hrn.nye.movieplayer/img.png");
  // System.out.println(workingDir);
  // File file = new File(loadImage.class.getResource("img1.jpg").toString());
  Image img = new Image(f.toURI().toString());
  ImageView imv = new ImageView(img);
  Group root = new Group();
  root.getChildren().add(imv);
  Scene scene = new Scene(root);
  primaryStage.setScene(scene);
  primaryStage.show();
} catch (Exception e) {
  System.out.println(e);
}
