如果d盘不是你web服务器的路径，你可以用FileInputStream

String basePath = request.getSession().getServletContext().getRealPath("d:/路径");  
        //System.out.println(basePath);  
        String filedisplay = "文件名.doc";  
        String filedownload = basePath + File.separator + "文件名.doc";  
        System.out.println("----------------------"+filedownload);  
        response.setContentType("applicaiton/x-download");  
        response.addHeader("Content-Disposition", "attachment;filename="+filedisplay);  

        InputStream is = null;  
        OutputStream os = null;  
        BufferedInputStream bis = null;  
        BufferedOutputStream bos = null;  

        is = new FileInputStream(new File(filedownload));  
        bis = new BufferedInputStream(is);  
        os = response.getOutputStream();  
        bos = new BufferedOutputStream(os);  

        byte[] b = new byte[1024];  
        int len = 0;  
        while((len = bis.read(b)) != -1){  
            bos.write(b,0,len);  
        }  

        bis.close();  
        is.close();  
        bos.close();  
        os.close();
