我想使用 jar 文件中的 java 代码作为资源播放 .wav 文件.我的代码看起来像这样 -

I want to play a .wav file using java code which is in a jar file as resource. My code is look like this -

try {
     URL defaultSound = getClass().getResource("/images/ads/WindowsNavigationStart.wav");
     // getClass().getSy.getResource("/images/ads/WindowsNavigationStart.wav");
     File soundFile = new File(defaultSound.toURI());
     AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(soundFile);
     Clip clip = AudioSystem.getClip();
     clip.open(audioInputStream);
     clip.start( );
} catch (Exception ex) {
     ex.printStackTrace();
}

请给我一个解决方案.谢谢大家.

Please give me a solution. Thank you all.

推荐答案

更改:

AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(soundFile);

致:

System.out.println("defaultSound " + defaultSound);  // check the URL!
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(defaultSound);
