读取的问价格式如下：

直接上代码：
controller层

 @ApiOperation(value = "全自动导入资源和编目")@PostMapping("/autoExcelToSql")public Response readExcelToList(@RequestPart("file") MultipartFile file) throws IOException, BizException {String filename = file.getOriginalFilename();Assert.isNull(filename, "无法获取文件信息");Assert.isTrue(!filename.contains(".xls"), "上传文件类型错误");// 获取文件输入流InputStream inputStream = file.getInputStream();// 获取excel工作簿对象List<AutoExcelToSqlDTO> tableInfos = new ArrayList<>();String substring = filename.substring(filename.lastIndexOf("."), filename.length());if (".xls".equals(substring)) {HSSFWorkbook workbook = new HSSFWorkbook(file.getInputStream());tableInfos = rdResourceDirService.excelToList(workbook);} else if (".xlsx".equals(substring)) {XSSFWorkbook workbook = new XSSFWorkbook(file.getInputStream());//tableInfos = excelxToList(workbook);}// 关闭输入流log.info("tableInfos=" + tableInfos);inputStream.close();return Response.success(tableInfos);}
