在Linux服务器上运行Java代码时，如果涉及到音频处理，可能会遇到一些在Windows上不存在的问题。尤其是在处理音频文件时，javax.sound.sampled.Clip接口在Linux上的兼容性可能会有问题。这是因为Clip依赖于底层的音频系统，而这些系统在不同的操作系统之间实现不同。
该方法在windows上正常
private String getWavDuration(MultipartFile file) {try (BufferedInputStream bis = new BufferedInputStream(file.getInputStream())) {Clip clip = AudioSystem.getClip();clip.open(AudioSystem.getAudioInputStream(bis));long durationInMillis = (long) (clip.getMicrosecondLength() / 1000);long seconds = TimeUnit.MILLISECONDS.toSeconds(durationInMillis);return seconds + "s";} catch (Exception e) {e.printStackTrace();throw new RuntimeException("无法获取 WAV 文件时长", e);}}错误信息
