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：

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