为什么它不起作用？我尝试更改文件名，路径仍然无法正常工作。我得到了很多的惊吓。我不知道这段代码有什么问题。文件路径/Users/Mariusz/Music/Audio.mp3
我改变了我的代码，但仍然无法正常工作。
if(e.getActionCommand().equals("Play")) {
bar.setString(file.getName().split(".mp3")[0]);
playSound(file);
}
public void playSound(File file){
String bip = file.toURI().toString();
Media hit = new Media(bip);
MediaPlayer mediaPlayer = new MediaPlayer(hit);
mediaPlayer.play();
}

Media constructor采用URI，而不是文件路径说明符。
构造函数在JavaFX 2.2中具有以下约束：
当前file.getPath()调用返回的空格字符在URI中是非法的。
要成为有效的URI，必须将' '编码为%20。
要为文件构造URI，请调用file.toURI()而不是当前对file.getPath()的调用。
