EasyExcel 读取xls 监听行数据问题

需求：导入xls 文件 需要判断是否空值，时间格式是否问题

监听器

 调用监听器

    @Transactional(rollbackFor = Exception.class)
    public void importUserDocAndUser(MultipartFile file, String bilitime) throws IOException {
        List<RevWaterUserDocAndUserPayImportExl> list = new ArrayList<>();

                new ExcelListener(list)).head(RevWaterUserDocAndUserPayImportExl.class).headRowNumber(1).sheet().doReadSync();
        if (revWaterUserDocImpExlList.size() >= 10000) {
            throw new RuntimeException("数据量大,单次批量导入超过10000条");
        }
        // 其他逻辑
    }
