我正在尝试实现我使用 Scene Builder 开发的相同界面。但是由于某种原因，CSS 没有加载。 这才是我该得到的! 这就是我得到的!
Parent root;
try {
root = FXMLLoader.load(getClass().getResource("/path../path../TutorControlPanel.fxml"));
Stage stage = new Stage();
stage.setTitle("Tutor Control Panel");
stage.setScene(new Scene(root, 950, 750));
stage.show();
} catch (IOException ex) {
Logger.getLogger(LoginController.class.getName()).log(Level.SEVERE, null, ex);
}
} else {
System.out.println("user not found");
}
}
} catch (SQLException ex) {
Logger.getLogger(LoginController.class.getName()).log(Level.SEVERE, null, ex); }
XML 从这里开始!

请您参考如下方法:
我必须进行 2 处更改才能获得预期结果
1.首先将所有图片放入Style.css所在文件夹
2.其次，添加这几行代码:
String css = this.getClass().getResource("Style.css").toExternalForm(); scene.getStylesheets().add(css);
try {
Parent root=FXMLLoader.load(getClass().getResource("/eLearning/UserInterface/TutorControlPanel.fxml"));
Scene scene = new Scene(root);
String css = this.getClass().getResource("Style.css").toExternalForm();
scene.getStylesheets().add(css);
Stage stage = new Stage();
stage.setTitle("Tutor Control Panel");
stage.setScene(scene);
stage.show();
} catch (IOException ex) {
Logger.getLogger(LoginController.class.getName()).log(Level.SEVERE, null, ex);
}
} else {
System.out.println("user not found");
}
}
} catch (SQLException ex) {
Logger.getLogger(LoginController.class.getName()).log(Level.SEVERE, null, ex);
}
