关于JavaFx的问题——捣鼓了一下午都还没好

Question

我真的快FENG了 ，就是单纯想写个gui的小工具，我不熟悉.net，c#之类的，于是只能拿java来写，本来也不是啥大事，awt和swing都有点老了而且很难看，我就打算用javafx写，ui还好看一下而且界面与代码分类非常不辍，但是没想到偏偏就导个fxml愣是导不进去，捣鼓了一下午愣是没发现问题在哪。所以想问问如何解决

源码：

package me.ctimet.BektTranslationTools;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class Main extends Application
{
    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage stage) throws Exception {
        FXMLLoader loader = new FXMLLoader(getClass().getResource("me/ctimet/BektTranslationTools/fxml/fxmlOne.fxml"));
        Scene scene = new Scene(loader.load(),900,600);
        stage.setScene(scene);
        stage.show();
    }
}

报错：

可以试试这样写

Parent root = FXMLLoader.load(getClass().getResource("fxml/fxmlOne.fxml"));
primaryStage.setTitle("Hello World");
Scene scene = new Scene(root, 300, 275);
primaryStage.setScene(scene);
primaryStage.show();
