如何用Java播放声音？

Question

我希望能够在我的程序中播放声音文件。我应该去哪里？

Answer 1

我不想有那么多行代码只是为了播放一个简单的该死的声音。如果您有 JavaFX 包（已经包含在我的 jdk 8 中），这可以工作。

private static void playSound(String sound){
    // cl is the ClassLoader for the current class, ie. CurrentClass.class.getClassLoader();
    URL file = cl.getResource(sound);
    final Media media = new Media(file.toString());
    final MediaPlayer mediaPlayer = new MediaPlayer(media);
    mediaPlayer.play();
}

注意：您需要初始化JavaFX。一种快速的方法是在您的应用程序中调用一次JFX面板（）的构造函数：

static{
    JFXPanel fxPanel = new JFXPanel();
}

一个不好的例子:

import  sun.audio.*;    //import the sun.audio package
import  java.io.*;

//** add this into your application code as appropriate
// Open an input stream  to the audio file.
InputStream in = new FileInputStream(Filename);

// Create an AudioStream object from the input stream.
AudioStream as = new AudioStream(in);         

// Use the static class member "player" from class AudioPlayer to play
// clip.
AudioPlayer.player.start(as);            

// Similarly, to stop the audio.
AudioPlayer.player.stop(as);

我写了以下运行良好的代码。但我认为它只适用于< code >。wav格式。

public static synchronized void playSound(final String url) {
  new Thread(new Runnable() {
  // The wrapper thread is unnecessary, unless it blocks on the
  // Clip finishing; see comments.
    public void run() {
      try {
        Clip clip = AudioSystem.getClip();
        AudioInputStream inputStream = AudioSystem.getAudioInputStream(
          Main.class.getResourceAsStream("/path/to/sounds/" + url));
        clip.open(inputStream);
        clip.start(); 
      } catch (Exception e) {
        System.err.println(e.getMessage());
      }
    }
  }).start();
}
