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

@Overridepublic void uploadWord(MultipartFile file) throws IOException {//读取文本XWPFDocument document = new XWPFDocument(file.getInputStream());List<XWPFTable> tables = document.getTables();List<XWPFTableRow> rows = null;List<XWPFTableCell> cells;List list = new ArrayList();//起始打印cell；int w = 17;//14一循环int l = 14;Construction construction = new Construction();for (XWPFTable table : tables) {rows = table.getRows();for (XWPFTableRow row : rows) {cells = row.getTableCells();for (XWPFTableCell cell : cells) {list.add(cell.getText());}}}String packageNum = null;for (int i = w; i < list.size(); i += 14) {//下标写死就是一直取第一个值String submarkNum = (String) list.get(16);construction.setSubmarkNum(submarkNum);//写逻辑判断，把空值填上上一个if (!((String) list.get(i)).isEmpty()) {packageNum = (String) list.get(i);construction.setPackageNum(packageNum);while (((String) list.get(i)).isEmpty()) {packageNum = (String) list.get(i - l);construction.setPackageNum(packageNum);}}String projectCom = (String) list.get(i + 1);construction.setProjectCom(projectCom);String projectName = (String) list.get(i + 2);construction.setProjectName(projectName);String projectAbs = (String) list.get(i + 3);construction.setProjectAbs(projectAbs);String eleLevel = (String) list.get(i + 4);construction.setEleLevel(eleLevel);String projectPlan = (String) list.get(i + 5);construction.setProjectPlan(projectPlan);String projectNature = (String) list.get(i + 6);construction.setProjectNature(projectNature);String projectScale = (String) list.get(i + 7);construction.setProjectScale(projectScale);String methods = (String) list.get(i + 8);construction.setMethods(methods);String limitPrice = (String) list.get(i + 9);construction.setLimitPrice(limitPrice);String technologyId = (String) list.get(i + 10);construction.setTechnologyId(technologyId);String biddingFee = (String) list.get(i + 11);construction.setBiddingFee(biddingFee);String requestId = (String) list.get(i + 12);construction.setRequestId(requestId);elemapper.uploadWord(construction);}}
