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

java 复制代码

 @Override
    public 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

java 复制代码

//唯一不同为要使用HSSF创建
 Workbook workbook1 = new HSSFWorkbook(new FileInputStream(fullAddress));

word使用

java 复制代码
