Java播放音頻拋出IOException

Question

在互聯網上搜索了如何用Java播放音頻的方法，嘗試了多種方法，但都失敗之后，我決定發表一篇文章。 這是我播放音頻的方式：

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

這是一個例外：

Answer 1

您永遠不要直接在sun.*包中使用類，它們不是標准JDK的一部分...
嘗試

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();

兩個警告：

• 僅適用於WAV文件
• 音頻在另一個線程中運行，如果應用程序（例如SSCCE）在start()命令后立即終止，則音頻播放會在開始之前被終止，您將聽不到任何聲音...
