已经能导出了，只是路径是写死的，怎么修改才能 出现可以选择保存路径的框？ 望指导！

以下是部分代码::

String fileName = "硬件查询信息.xls";  
            fileName = new String(fileName.getBytes("GBK"), "iso8859-1");  
            response.reset();  
            response.setHeader("Content-Disposition", "attachment;filename=" + fileName);// 指定下载的文件名  
            response.setContentType("application/vnd.ms-excel");  
            response.setHeader("Pragma", "no-cache");  
            response.setHeader("Cache-Control", "no-cache");  
            response.setDateHeader("Expires", 0);  
          //  OutputStream output = response.getOutputStream();  
            FileOutputStream  bufferedOutPut = new FileOutputStream ("C:/硬件查询信息.xls");  
            

最后关闭的代码::

try{
            bufferedOutPut.flush();  
            wb.write(response.getOutputStream());
            bufferedOutPut.close(); 
        }catch (IOException e) {  
            e.printStackTrace();  
        } finally {  
            Exportlist.clear();  
        }
