JavaFx音频在秒后停止

Question

我遇到问题。我这个代码：

  URL thing = getClass().getResource(Song); 
     Media audioFile = new Media(thing.toString()); 
     MediaPlayer m = new MediaPlayer(audioFile); 
     m.setAutoPlay(true); 

如果我运行这段代码，我的MP3 gegins玩，但STOPP AFER几秒钟！ 我不想，音频文件停止。

如果你希望它在整个声音文件播放，您必须使用MediaView。

这里有一个基本的例子所在的文件“请将test.mp3”是在相同的目录类：

import javafx.application.Application; 
import javafx.scene.Group; 
import javafx.scene.Scene; 
import javafx.scene.media.Media; 
import javafx.scene.media.MediaPlayer; 
import javafx.scene.media.MediaView; 
import javafx.stage.Stage; 
import java.net.URL; 

public class MusicPlayer extends Application { 

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

    @Override 
    public void start(Stage primaryStage) { 
     Group root = new Group(); 
     Scene scene = new Scene(root, 540, 210); 

     primaryStage.setTitle("Music Player"); 
     primaryStage.setScene(scene); 
     primaryStage.show(); 

     final URL resource = getClass().getResource("test.mp3"); 
     Media media = new Media(resource.toString()); 
     MediaPlayer mediaPlayer = new MediaPlayer(media); 
     mediaPlayer.setAutoPlay(true); 

     MediaView mediaView = new MediaView(mediaPlayer); 
     ((Group)scene.getRoot()).getChildren().add(mediaView); 
    } 
}
