java - 加载 FXML 文件期间未找到文件异常

Question

FXMLe1.java:

package fxmle1; 
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.GridPane;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class FXMLe1 extends Application {

@Override
public void start(Stage primaryStage) throws Exception{


   Parent panel = FXMLLoader.load(getClass().getResource("FXMLe1.fxml"));        
   Scene scene = new Scene(panel, 300, 250);

    primaryStage.setTitle("Hello World!");
    primaryStage.setScene(scene);
    primaryStage.show();
}

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

}

FXMLe1.fxml:

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

<?import javafx.geometry.Insets?>
<?import javafx.scene.layout.GridPane?>

<?import javafx.scene.control.Button?>
<?import javafx.scene.control.Label?>
<?import javafx.scene.layout.BorderPane?>

<GridPane fx:id="root" prefHeight="400.0" prefWidth="600.0"  xmlns:fx="http://javafx.com/fxml/1" fx:controller="fxmle1.FXMLe1Controller">
    <BorderPane>
        <top>
            <Label text = "Test Javafx"/>    
        </top>
        <center>
            <Button text = "test"/>
        </center> 
    </BorderPane>    
    <stylesheets>
       
    </stylesheets>
</GridPane>

FXMLe1Controller.java:

package fxmle1;

import java.net.URL;
import java.util.ResourceBundle;
import javafx.fxml.Initializable;


public class FXMLe1Controller implements Initializable {

/**
 * Initializes the controller class.
 */
@Override
public void initialize(URL url, ResourceBundle rb) {
    // TODO
}    

}

大家好! 所以我尝试使用 FXML 制作一个 JavaFX 项目，但不幸的是，我遇到了这个问题:

Exception running application fxmle1.FXMLe1
Java Result: 1

我尝试在互联网上寻找解决方案，但这对我没有多大帮助。 我还寻找了使我的项目崩溃的代码，那就是:

 Parent panel = FXMLLoader.load(getClass().getResource("FXMLe1.fxml"));

那么，有人对此有答案吗？)如果有的话，我会很高兴你告诉我。

Answer 1

将您的FXMLe1.fxml放入resources文件夹中，然后尝试

Parent panel = FXMLLoader.load(getClass().getResource("/FXMLe1.fxml"));

这应该可以作为您的解决方案
