java 代码：

1. publicclass TestOpenExcel extends HttpServlet {  

3. privatestaticfinal String url = "D:/test.xls";  

5. protectedvoid doGet(HttpServletRequest request,  

6.   HttpServletResponse response) throws ServletException, IOException {  

8.  /**

9.   * setContentType设置MIME类型，Acrobat

10.   * PDF文件为"application/pdf"，WORD文件为："application/msword"，

11.   * EXCEL文件为："application/vnd.ms-excel"。

12.   */  

13.  response.setContentType("application/vnd.ms-excel");  

14.  /**

16.   */  

17. response.setHeader("Content-disposition", "inline;filename="" + "test.xls"+ "";");  

19.  ServletOutputStream sos = response.getOutputStream();  

20.  FileInputStream fis = new FileInputStream(url);    

21.    

22.  BufferedOutputStream bos = new BufferedOutputStream(sos);    

23.  byte[] bytes = newbyte[8192];    

24.  bos.write(bytes, 0, fis.read(bytes));  

25.  fis.close();    

26.  sos.close();    

27.  bos.close();  

30. }  

33. protectedvoid doPost(HttpServletRequest request,  

34.   HttpServletResponse response) throws ServletException, IOException {  

35.  doGet(request, response);  

36. }
