并不是每一場導出excel都報錯，只是偶爾。然后導出的excel表無法打開，也無法修復。
/**生成報表*/ String filename = "報表"+TimeUtil.getCurrentTime()+".xls";
try { filename = new String(filename.getBytes("GBK"), "ISO-8859-1"); } catch (UnsupportedEncodingException e) { logger.error("下載報表無效字符集"); } response.addHeader("Content-Disposition", "attachment;filename="+filename); response.setContentType("application/octet-stream"); OutputStream outputStream = null; try { outputStream = response.getOutputStream(); wb.write(outputStream);//------報錯行-- outputStream.flush(); outputStream.close(); } catch (IOException e) { logger.error("下載報表異常：",e); }finally{ try { if(outputStream!=null){ outputStream.close(); } } catch (IOException e) { logger.error("下載報表流關閉異常"); } }
?
下面是報錯信息：
