直接把这个OutputStream写到response中去?

  String strContent = "234242423424234";
  int iLength = strContent.length();
  response.setContentType("application/x-msdownload"); //application/doc -> *.doc
  response.setHeader("Content-Disposition", "attachment; filename=".concat("normal.bin"));
  response.setContentLength(iLength);  response.getOutputStream().write(strContent.getBytes());
  response.getOutputStream().flush();
  response.getOutputStream().close();
