分析：

使用Hutool工具包的ExcelReader.read()方法报错，因为poi3.17版本的Cell.getCellType()返回int而不是org.apache.poi.ss.usermodel.CellType。

public List<List<Object>> readData(MultipartFile file) {
        List<List<Object>> resultList = new ArrayList<>();
        try {
            //读取数据
            ExcelReader reader = ExcelUtil.getReader(file.getInputStream());
            resultList = reader.read();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return resultList;
    }

package cn.hutool.poi.excel.cell;

解决方法：

加入Poi4.0.0依赖即可。
