at org.apache.poi.ss.usermodel.WorkbookFactory.create(WorkbookFactory.java:75)

在建立Workbook時使用HSSFWork讀取xls檔案字尾時出現過,切換為WorkbookFactory.creat(new FileInputStream("xx"));
異常資訊:
Unable to read entire header; 0 bytes read; expected 512 bytes
方法程式碼如下:
private static void resolveOnlyTextKlp(){ String localFilePath = "E:\\extractKlp\\bak\\onlyTextKlp.xlsx"; int circleNum = 10; int excelIndex = 1; FileInputStream input = null; FileOutputStream output = null; try { input = new FileInputStream(new File(localFilePath)); output = new FileOutputStream(new File(localFilePath)); Workbook workbook = WorkbookFactory.create(input); Sheet klpSheet = workbook.getSheetAt(0); for(int i=0;i<circleNum;i++){ //追加至excel文件中 Row writeRow = klpSheet.createRow(excelIndex++); Cell cell_1 = writeRow.createCell(0); Cell cell_2 = writeRow.createCell(1); Cell cell_3 = writeRow.createCell(2); //知識標題 cell_1.setCellValue("標題oo"+i); //知識型別 cell_2.setCellValue("型別oo"+i); //知識內容 cell_3.setCellValue("內容oo"+i); } // output = new FileOutputStream(new File(localFilePath)); workbook.write(output); output.flush(); }catch (Exception e) { e.printStackTrace(); }finally{ try { if(input!=null)input.close(); if(output!=null)output.close(); } catch (IOException e) { e.printStackTrace(); } } }
在上面我同時建立輸入輸入流就會出現該錯誤Your InputStream was neither an OLE2 stream, nor an OOXML stream
解決辦法:
將上面的output註釋開啟下面的output;即不在建立Workbook之前建立多個對同一個檔案處理的流物件。
有錯請指正,一同學習進步!
