Java中通过POI读取Excel 2003 - 2007的xls,xlsx格式

@Testpublic void testRead() throws IOException, InvalidFormatException {// String fileName = "e:/workbook.xls";String fileName = "e:/workbook.xlsx";Workbook wb = WorkbookFactory.create(new FileInputStream(fileName));int sheetNum = wb.getNumberOfSheets();for (int i = 0; i < sheetNum; i++) {Sheet childSheet = wb.getSheetAt(i);int rowNum = childSheet.getLastRowNum();for (int j = 0; j < rowNum; j++) {Row row = childSheet.getRow(j);int cellNum = row.getLastCellNum();for (int k = 0; k < cellNum; k++) {System.out.print(row.getCell(k).toString() + " ");}System.out.println();}}}
