我覺得主要是紅色部分那裏需要解決

stage.setScene(scene);
stage.show();

launch(args);

[花谢尊前不敢香]

应该是没有参数引起的

改为
public static void main(String[] args) {  
        launch(new String[]{"a","b"});  
    }  

看下

謝謝fangmingshijie剛剛嘗試了 但是結果還是一樣 我原本有另一個.FXML也是同樣的問題，我讓event類別extends AnchorPane類別後就可以正常執行了，但這個用這招好像也沒辦法，還是不知道哪裡出問題。
