Java加载异常命名空间方法处理程序

您好，我正在尝试使用场景生成器和fxml构建银行用户界面。但是，当我尝试加载第二个屏幕时，

#bro

函数会给我一个错误。当我取消该功能时，程序将打开第二个屏幕，没有任何错误

这是我得到的全部错误：

在第二个屏幕fxml中，我没有找到这个错误处理程序方法，下面是代码，bro用红色下划线：

 <Button fx:id="romana" layoutX="468.0" layoutY="128.0" mnemonicParsing="false" onAction="#bro" prefHeight="36.0" prefWidth="49.0" />

屏幕二控制器：

import java.net.URL;
import java.util.ResourceBundle;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.scene.image.ImageView;
import javafx.scene.shape.Rectangle;
import javafx.fxml.Initializable;
import javafx.scene.input.MouseEvent;

public class UnuController implements Initializable {
    private Baza baza;
    @FXML
    private ImageView im1;

    public void setBaza(Baza baza) {
        this.baza = baza;
    }



    @FXML
    private Rectangle welcome;

    void fff96f(ActionEvent event) {

    }



      @Override
    public void initialize(URL url, ResourceBundle rb) {
        // TODO
    }  

    @FXML
    private void intra(MouseEvent event) {
        baza.incarcDoi();
    }


}

可能在“fx:controller”中选择的java类不正确。检查您是否选择了正确的java类（在您的例子中是DoiController）。可能是操作#bro在您的fxml文件中，但不在DoiController中。

bro方法的代码在哪里？bro方法在第二屏控制器中
