您好我正在尝试使用场景构建器和fxml构建银行UI。但是，当我尝试加载第二个屏幕时，#bro函数给出了一个错误。当我取消该功能时，程序会打开第二个屏幕，没有任何错误。
这是我得到的完整错误：

在第二个屏幕fxml中，我收到此错误处理程序方法未找到，这里是代码，而下划线用红色加下划线：
<Button fx:id="romana" layoutX="468.0" layoutY="128.0" mnemonicParsing="false" onAction="#bro" prefHeight="36.0" prefWidth="49.0" />
屏幕一个控制器：
package atm4;
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

baza.incarcDoi();

答案 0 :(得分：0)
在“fx：controller”中选择的java类可能不正确。检查你是否选择了正确的java类，在你的情况下是DoiController。可能是#bro的行为在你的fxml文件中，但不在DoiController中。
