excel 分为两个版本，一个是xlsx一个是xls
xlsx为高版本，xls为低版本
xlsx高版本
@Overridepublic void uploadExcel(MultipartFile file) throws IOException {// Workbook workbook = new XSSFWorkbook(new FileInputStream("D:\\xxx\\xxx.xlsx"));Workbook workbook = new XSSFWorkbook(file.getInputStream());//获取excel中的指定表单，两种方法都可以// Sheet sheet = workbook.getSheetAt(4);Sheet sheet = workbook.getSheet("工程项目投标报价汇总表");int lastRowNum = sheet.getLastRowNum();//当前sheet的最后一行的索引值//读取工作表的内容Row row = null;for (int i = 3; i <= lastRowNum; i++) {row = sheet.getRow(i);Bidding bidding = new Bidding();String tableId = row.getCell(0).getStringCellValue(); //序号bidding.setTableId(tableId);String projectName = row.getCell(1).getStringCellValue(); //项目或费用名称bidding.setProjectName(projectName);String amountM = row.getCell(2).getStringCellValue(); //金额bidding.setAmountM(amountM);String comment = row.getCell(3).getStringCellValue(); //备注bidding.setComment(comment);elemapper.uploadExcel(bidding);}}xls低版本
//唯一不同为要使用HSSF创建Workbook workbook1 = new HSSFWorkbook(new FileInputStream(fullAddress));
word使用
