java - 使用 java 将 jar 中的 .wav 文件作为资源播放

Question

我想使用 jar 文件中的 java 代码作为资源播放 .wav 文件。我的代码是这样的 -

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();
}

WindowsNavigationStart.wav 文件存在于我的一个 jar 文件中。但是得到以下异常 -

java.lang.IllegalArgumentException: URI is not hierarchical

请给我一个解决方案。谢谢大家。

你试过吗:

InputStream is= getClass().getResourceAsStream("/images/ads/WindowsNavigationStart.wav");
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(is);

基本上，我认为您不能从 jar 文件中的 URI 创建文件。但是你可以直接传递输入流。
