在Jar

Question

我的程序在Netbeans中运行完美。当我尝试执行jar时，只加载主页面。当您尝试进行转换时，程序会挂起并提供classdefnotfoundexception。当我尝试加载新的fxml时，似乎会出现此问题。

这是我的主要课程。

主类 - 启动代码

public void start(Stage primaryStage) throws Exception 
{

    stage = primaryStage;


    splashScreen();

    stage.setFullScreenExitKeyCombination(NO_MATCH);
    stage.setFullScreen(true);
    primaryStage.show();
}

splashScreen方法

public void splashScreen()
{
    try {
        FXMLDocumentController splash = (FXMLDocumentController) replaceSceneContent("FXMLDocument.fxml");
        splash.setApp(this);
    } catch (Exception ex) {
        Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
    }
}

FXMLDocument方法，用于启动挂起发生的转换。

@FXML
private void handleButtonAction(KeyEvent event) throws IOException, Exception 
{

    if(event.getCode() == KeyCode.A)
  {

    Random randomGenerator = new Random();
    int randomInt = randomGenerator.nextInt(100);
    if(randomInt % 2 > 0)
    {
        application.playVid();
    }
    else
    {
        application.playVid1();
    }
  }

}

两种playvid方法都是一样的。他们只是播放不同的视频。但 这是playvid方法。

public void playVid() throws IOException 
{
    try {
        FXMLVideoController eatingVid = (FXMLVideoController) replaceSceneContent("FXMLVideo.fxml");
        eatingVid.setApp(this);
    } catch (Exception ex) {
        Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
    }
}

最后，切换fxml文件的replaceSceneContent方法。

private Initializable replaceSceneContent(String fxml) throws Exception              {
    FXMLLoader loader = new FXMLLoader();
    InputStream in = FeedingStationV5.class.getResourceAsStream(fxml);
    loader.setBuilderFactory(new JavaFXBuilderFactory());
    loader.setLocation(FeedingStationV5.class.getResource(fxml));
    AnchorPane page;
    try {
        page = (AnchorPane) loader.load(in);
    } finally {
        in.close();
    } 
    Scene scene = new Scene(page);
    stage.setScene(scene);
    stage.setFullScreenExitKeyCombination(NO_MATCH);
    stage.setFullScreen(true);
    stage.sizeToScene();
    return (Initializable) loader.getController();
}

值得注意的另一件事是我加载视频文件的方式。我不确定这是否是问题，但我使用这种方法。

File eatingVid = new File("src/feeding/station/v5/eating.mp4");
Media eatingV = new Media(eatingVid.toURI().toString());
MediaPlayer eating = new MediaPlayer(eatingV);

对于任何感兴趣的人，fxml文件

<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.media.*?>
<?import java.lang.*?>
<?import java.util.*?>
<?import javafx.scene.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>

<AnchorPane id="AnchorPane" prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1" fx:controller="feeding.station.v5.FXMLVideoController">
   <children>
      <MediaView fx:id="mediaView" />

   </children>
</AnchorPane>

这是出现的堆栈错误。
