使用fxml

Question

所以我用Fxml制作了非常简单的应用程序，只有标签和文本字段，还有两个按钮，但是我得到了这个错误..

应用程序启动方法中的异常

这是代码

<?xml version="1.0" encoding="UTF-8*?>

<?import javafx.scene.layout.GridPane?>
<?import javafx.geometry.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.text.*?>
<?import java.lang.*?>
<?import javafx.scene.layout.*?> 

<GridPane alignment="CENTER" hgap="5.0" vgap="5.0">
    <children>
        <Text text="Dodavanje Kupca" GridPane.columnIndex="0" GridPane.rowIndex="0" GridPane.columnSpan="2">
        <font>
          <Font size= "30.0"/> 
        </font>
    </Text>
    <Label text="Ime Kupca" GridPane.columnIndex="0" GridPane.rowIndex="2"/>
    <Label text="Prezime Kupca" GridPane.columnIndex="0" GridPane.rowIndex="3"/>
    <Label text="Adresa Kupca" GridPane.columnIndex="0" GridPane.rowIndex="4"/>
    <Label text="Email Kupca" GridPane.columnIndex="0" GridPane.rowIndex="5"/>
    <Label text="Telefon Kupca" GridPane.columnIndex="0" GridPane.rowIndex="6"/>
    <TextField GridPane.columnIndex="1" GridPane.rowIndex="2"/>
    <TextField GridPane.columnIndex="1" GridPane.rowIndex="3"/>
    <TextField GridPane.columnIndex="1" GridPane.rowIndex="4"/>
    <TextField GridPane.columnIndex="1" GridPane.rowIndex="5"/>
    <TextField GridPane.columnIndex="1" GridPane.rowIndex="6"/>
<HBox alignment="TOP_RIGHT" GridPane.columnIndex="1" GridPane.rowIndex="7">
    <children>
        <Button mnemonicParsing="true" text="Save"/>
        <Button mnemonicParsing="true" text="Clear"/>
    </children>
</HBox>
    </children>

    <padding>
        <Insets bottom="16.0" left="15.0" right="15.0" top="15.0"/>
    </padding>
</GridPane>

以下是主要课程：

package main;
import java.net.URL;
import javafx.application.Application;
import static javafx.application.Application.launch;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.GridPane;
import javafx.stage.Stage;

public class test extends Application {

    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage stage) throws Exception {
    URL fxmlUrl= getClass().getClassLoader().getResource("view.fxml");
    GridPane root= FXMLLoader.<GridPane>load(fxmlUrl);

    Scene scena = new Scene(root);
    stage.setScene(scena);
    stage.show();

    }
}

对不起。 这是堆栈跟踪的另一个编辑。 堆栈跟踪有点太大所以再次生病类型有些无意义
