XMLStreamException:打开新阶段(新窗口)时，[row，col]处出现ParseError

Question

我正试图从一个窗口切换到另一个窗口。

这是我的代码：

public class SelectTypeController implements Initializable {
@FXML
private Button buttonVai;
@FXML
private ComboBox<String> comboBox;
@FXML
private AnchorPane rootPane;
@Override
public void initialize(URL location, ResourceBundle resources) {
ObservableList<String> observableListOfAccomodations = FXCollections.observableArrayList("1", "2", "3");
comboBox.setItems(observableListOfAccomodations);
buttonVai.setDisable(true);
}
@FXML
public void comboChanged() {
buttonVai.setDisable(false);
}
@FXML
public void showCrudPage() {
switch (comboBox.getValue()) {
case "3":
showCrudPageRestaurantScene();
break;
}
}
// this is giving problem
public void showCrudPageRestaurantScene() {
try {
Parent parent = FXMLLoader.load(SelectTypeController.class.getResource("/crud_restaurant.fxml"));
Stage stage = new Stage();
Scene scene = new Scene(parent);
stage.setScene(scene);
stage.show();
} catch (IOException e) {
e.printStackTrace();
}
}
}

管理以下fxml视图select_type.fxml

<AnchorPane
fx:id="rootPane"
xmlns:fx="http://javafx.com/fxml/1" fx:controller="controllers.SelectTypeController" maxHeight="-Infinity"
maxWidth="-Infinity"
minHeight="-Infinity" minWidth="-Infinity" prefHeight="800.0" prefWidth="1280.0"
xmlns="http://javafx.com/javafx/11.0.1">
<ImageView fitHeight="800.0" fitWidth="1280.0" pickOnBounds="true">
<Image url="images/3156482.jpg"/>
</ImageView>
<Pane layoutX="440.0" layoutY="307.0" opacity="0.8" prefHeight="200.0" prefWidth="400.0"
style="-fx-background-color: #06BCAD; -fx-background-radius: 20;"/>
<Pane layoutX="336.0" layoutY="206.0" prefHeight="336.0" prefWidth="608.0">
<Label layoutX="200.0" layoutY="29.0" text="Seleziona una tipologia">
<font>
<Font size="20.0"/>
</font>
</Label>
<Button fx:id="buttonVai" layoutX="260.0" layoutY="250.0" mnemonicParsing="false"
onMouseClicked="#showCrudPage"
style="-fx-background-color: #0078D7;" text="Vai" textFill="white"/>
</Pane>
<ComboBox fx:id="comboBox" layoutX="512.0" layoutY="371.0" prefHeight="30.0" prefWidth="292.0"
promptText="Seleziona una tipologia"
onAction="#comboChanged"/>
</AnchorPane>

我想点击Vai按钮，我会被重定向到：

public class CrudRestaurant {
@FXML
private Label labelDescription;
}

管理

crud_restaurant.fxml

<AnchorPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="1080.0"
fx:controller="controllers.CrudRestaurant"
prefWidth="1920.0" xmlns="http://javafx.com/javafx/11.0.1" xmlns:fx="http://javafx.com/fxml/1">
<Label layoutX="828.0" layoutY="415.0" text="Placeholder"/>
</AnchorPane>

不幸的是，我遇到了一个例外：

javax.xml.stream.XMLStreamException：[行，列]处的ParseError：[3,6]

已解决

我在crud_restaurant.fxml文件中复制了<?xml version="1.0" encoding="UTF-8"?>。我的错。

只需删除一个多余的声明。
