JAVA按顺序播放多个wav音频

用Java按顺序播放多个音频部件，不是同时播放。代码如下：

            List<String> files = new ArrayList<String>();            files.add("barcode_prefix.wav");            for (char letter : barcode.toCharArray())            {                files.add(letter + ".wav");            }            files.add("barcode_suffix.wav");                        byte[] buffer = new byte[4096];            for (String file : files)            {                try                {                    AudioInputStream is = AudioSystem.getAudioInputStream(this.getClass().getResourceAsStream(file));                    AudioFormat format = is.getFormat();                    SourceDataLine line = AudioSystem.getSourceDataLine(format);                    line.open(format);                    line.start();                    while (is.available() > 0)                    {                        int len = is.read(buffer);                        line.write(buffer, 0, len);                    }                    line.drain(); // **[DEIT]** wait for the buffer to empty before closing the line                    line.close();                }                catch (Exception e)                {                    e.printStackTrace();                }            }

这个我在本地播放没有问题，放到服务器上会报错：

java.io.IOException: mark/reset not supported	at java.util.zip.InflaterInputStream.reset(Unknown Source)	at com.sun.media.sound.SoftMidiAudioFileReader.getAudioInputStream(Unknown Source)	at javax.sound.sampled.AudioSystem.getAudioInputStream(Unknown Source)	at com.yulong.mes.winapp.form.quality.ForBatchOperationForm$PlayAudioRunnable.run(ForBatchOperationForm.java:4317)	at java.lang.Thread.run(Unknown Source)


网上说要用BufferedInputStream封装一下。修改下代码确实如此：

 List<String> files = new ArrayList<String>();            files.add("barcode_prefix.wav");            for (char letter : barcode.toCharArray())            {                files.add(letter + ".wav");            }            files.add("barcode_suffix.wav");                        byte[] buffer = new byte[4096];            for (String file : files)            {                try                {                    InputStream stream = this.getClass().getResourceAsStream(file);                    InputStream bufferedIn = new BufferedInputStream(stream);                                        AudioInputStream is = AudioSystem.getAudioInputStream(bufferedIn);                    AudioFormat format = is.getFormat();                    SourceDataLine line = AudioSystem.getSourceDataLine(format);                    line.open(format);                    line.start();                    while (is.available() > 0)                    {                        int len = is.read(buffer);                        line.write(buffer, 0, len);                    }                    line.drain(); // **[DEIT]** wait for the buffer to empty before closing the line                    line.close();                }                catch (Exception e)                {                    e.printStackTrace();                }            }
