[在此输入图像描述] [1]这是驱动程序，程序将运行没有错误，但gui根本不会显示。我是FX的菜鸟，我只是想让它发挥作用。
public class Vacation extends Application {
private Stage stage;
@Override
public void start(Stage stage) throws Exception {
this.stage = stage;
try{
FXMLLoader loader = new
FXMLLoader(getClass().getResource("Vacation.fxml"));
AnchorPane pane = loader.load();
MainControler mainController = loader.getController();
Scene scene = new Scene(pane, 640, 450);
stage.setScene(scene);
stage.show();
}catch(IOException e){
}
}
public static void main(String[] args) {
launch(args);
}
}
这是FXML。

这是控制器。

@FXML public void BCButtonpress(ActionEvent event) {

bc.setScene(new Scene(root1));
bc.show();
}catch (IOException e){

在此先感谢任何帮助，我终于崩溃并决定发布这个，我找不到任何人，我的问题可能是一些小问题，但我没有一个新鲜的眼睛真的看看。道歉。
放入e.printStackTrace（）;在catch块中我得到了一个例外列表。

这是拼写错误。
<Button fx:id="DC" layoutX="229.0" layoutY="53.0" mnemonicParsing="false"
onAction="#DCbuttonpress" text="Devils CourtHouse" textFill="#ee0707"
/>enter
这是修复后运行后的异常。

表示onAction文件的第17行指定的Vacation.fxml处理程序存在问题。那条线是：
<Button fx:id="DC" ... onAction="#DCbuttonPpess" ... />
onAction属性中有一个明显的拼写错误：控制器类中定义的方法是
@FXML public void DCbuttonpress(ActionEvent event) {
/* ... */
}
所以FXML应该是
<Button fx:id="DC" ... onAction="#DCbuttonpress" ... />
