java - Javafx：添加图像：java.lang.reflect.InvocationTargetException

Question

在这里，我试图创建一个井字游戏板，但代码抛出异常当我使用绝对路径时显示无效的 url，所以我更改了它，但它仍然显示无效的 url 或在图像确实存在时找不到资源。

包装样品；

import javafx.application.Application;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.GridPane;
import javafx.stage.Stage;


public class Main extends Application {

    @Override
    public void start(Stage primaryStage) {

        GridPane pane = new GridPane();
        pane.setAlignment(Pos.CENTER);
        for (int i = 0; i < 3; i++) {
            for (int j = 0; j < 3; j++) {
                int random = (int) (Math.random() * 3);
                if (random != 2) {
                    String image = "file:///C:/Anime/A.pics/a1.jpg";
                    if(random>0){
                        image = "file:///C:/Anime/A.pics/a1.jpg";
                    }
                    else{
                        image = " file:///C:/Anime/A.pics/a2.jpg";
                    }
                    pane.add(new ImageView(new Image(image)), j, i);
                }
            }
        }
        Scene scene = new Scene(pane, 150, 150);
        primaryStage.setTitle("Tic Tac Toe");
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    public static void main(String[] args) {

        Application.launch(args);

    }

}

终端：
