使用Java servlet从Tomcat服务器下载mp3文件

ServletOutputStream stream = null;
BufferedInputStream buf = null;
try {
stream = response.getOutputStream();
File mp3 = new File(“/myCollectionOfSongs” + “/” + fileName);

  //set response headers  response.setContentType("audio/mpeg");  response.addHeader("Content-Disposition", "attachment; filename=" + fileName);  response.setContentLength((int) mp3.length());  FileInputStream input = new FileInputStream(mp3);  buf = new BufferedInputStream(input);  int readBytes = 0;  //read from the file; write to the ServletOutputStream  while ((readBytes = buf.read()) != -1)    stream.write(readBytes);} catch (IOException ioe) {  throw new ServletException(ioe.getMessage());} finally {  if (stream != null)    stream.close();  if (buf != null)    buf.close();}
