Posted by: newsletter Posted on: 2006-05-24 10:51 我写了一个下载的程序,在本地机器上测试的时候是可以下载到文件的,但是在其他机器上打开IE登陆我的系统后,下载功能可以实现,可是下载文件的内容却为空!请各位高手指导一下. String root = Coder.convertISO2UTF8(servlet.getServletContext().getRealPath("/")); String path = Coder.convertISO2UTF8(request.getParameter("path")); String name = request.getParameter("name"); name=Coder.convertISO2UTF8(name); response.setContentType("unknown"); response.addHeader("Content-Disposition", "filename=\"" + name + "\""); try { java.io.OutputStream os = response.getOutputStream(); java.io.FileInputStream fis = new java.io.FileInputStream(root + path + name); byte[] b = new byte[1024]; int i = 0; while ( (i = fis.read(b)) > 0 ) { os.write(b, 0, i); } fis.close(); os.flush(); os.close(); } catch ( Exception e ) { e.printStackTrace(); } |

Posted by: shgshg Posted on: 2006-06-08 10:45 你应该设置成xls类型啊: response.setContentType(".xls");,我是用的是专门写了一个配置文件作为路径的就可以了,保存在硬盘上就是*.xls |
