 throws IOException {
 FileInputStream fis = null;
 OutputStream os = null;
 try {
 fis = new FileInputStream("d:/log.png");
 os = response.getOutputStream();
 int count = 0;
 byte[] buffer = new byte[1024 * 8];
 while ((count = fis.read(buffer)) != -1) {
 os.write(buffer, 0, count);
 os.flush();
 }
 } catch (Exception e) {
 e.printStackTrace();
 } finally {
 try {
 fis.close();
 os.close();
 } catch (IOException e) {
