读取excel文件的内容：
public static void readExcel() throws InvalidFormatException, IOException { // Use a file Workbook wb1 = WorkbookFactory.create(new File("e:/test/userinfo.xls")); Sheet sheet = wb1.getSheetAt(0); // Decide which rows to process // int rowStart = Math.min(10, sheet.getFirstRowNum()); // int rowEnd = Math.max(40, sheet.getLastRowNum()); int rowStart = sheet.getLastRowNum(); int rowEnd = sheet.getLastRowNum() + 1; logger.info(sheet.getFirstRowNum()); logger.info(sheet.getLastRowNum()); for (int rowNum = rowStart; rowNum < rowEnd; rowNum++) { Row r = sheet.getRow(rowNum); int lastColumn = Math.max(r.getLastCellNum(), 10); logger.info(lastColumn); // To get the contents of a cell, you first need to know what kind // of cell it is (asking a string cell for its numeric contents will // get you a NumberFormatException for example). So, you will want // to switch on the cell's type, and then call the appropriate // getter for that cell. for (int cn = 0; cn < lastColumn; cn++) { // Cell cell = r.getCell(cn, Row.RETURN_BLANK_AS_NULL); Cell cell = r.getCell(cn); switch (cell.getCellType()) { case Cell.CELL_TYPE_STRING: logger.info(cell.getRichStringCellValue().getString()); break; case Cell.CELL_TYPE_NUMERIC: if (DateUtil.isCellDateFormatted(cell)) { logger.info(cell.getDateCellValue()); } else { logger.info(cell.getNumericCellValue()); } break; case Cell.CELL_TYPE_BOOLEAN: logger.info(cell.getBooleanCellValue()); break; case Cell.CELL_TYPE_FORMULA: logger.info(cell.getCellFormula()); break; default: logger.info("empty"); } } } } |
下面给出一个具体的例子，实例中的excel文件内容如下：
