Question

经过几个小时的互联网搜索如何用Java播放音频，尝试了许多不同的方法，并且所有方法都失败了，我决定发帖。以下是我播放音频的方式：

InputStream in = new FileInputStream(
                        System.getProperty("user.dir") + "/assets/sounds/"
                                + this.firePath);
                AudioStream audioStream = new AudioStream(in);
                AudioPlayer.player.start(audioStream);

以下是例外：

你不应该直接在sun.*包中使用类，它们不是标准JDK的一部分......
尝试

File file = new File(System.getProperty("user.dir") + "/assets/sounds/" + this.firePath);
AudioInputStream audioStream = AudioSystem.getAudioInputStream(file);

AudioFormat format = audioStream.getFormat();
DataLine.Info info = new DataLine.Info(Clip.class, format);
Clip audioClip = (Clip) AudioSystem.getLine(info);

audioClip.open(audioStream);
audioClip.start();

两个警告：

仅适用于WAV文件
音频在不同的线程中运行，如果应用程序（例如SSCCE）在start()命令之后立即终止，则音频播放在开始之前被终止，您将听不到任何内容......
