@RestController

            List<DataObject> dataList = parseExcel(tempFilePath);
            saveDataToDatabase(dataList);

            return "File uploaded successfully!";

        return dataList;
    }

    private void saveDataToDatabase(List<DataObject> dataList) {
        // 将数据插入到MySQL数据库中
        // 使用Spring Data JPA或者MyBatis等持久化框架进行操作
    }
