 6 
 7         /** 獲取文件的名稱 . */

13 
14         /** 將文件名稱進行編碼 */
15         response.setHeader("content-disposition","attachment;filename=" + URLEncoder.encode(fileName,"UTF-8"));
 
16         response.setContentType("content-type:octet-stream");
17         BufferedInputStream inputStream = new BufferedInputStream(new FileInputStream(file));
18         OutputStream outputStream = response.getOutputStream();
19         byte[] buffer = new byte[1024];
20         int len;
21         while
 
 ((len = inputStream.read(buffer)) != -1){ /** 將流中內容寫出去 .*/
22             outputStream.write(buffer ,0 , len);
23         }
