spring Boot上传excel文件报错。 1、http请求 2、上传类MultipartConfigFactory 设置? 400 报错

spring boot上传excel文件时报错（本地可以，线上报错），请大神解决...谢谢

问题见下描述

1、http请求

@RequestMapping("/batchAddPermissionVehicle")
@ResponseBody
public ResponseBase<Object> batchAddPermissionVehicle(MultipartFile file, @Param("userid") Integer userid) {
    ResponseBase<Object> res = new ResponseBase<>();
    HashMap<String, Object> data = new HashMap<>();
    int count = 0;
    try {
        String excelFileName = file.getOriginalFilename();
        boolean is03Excel = excelFileName.matches("^.+\\.(?i)(xls)$");
        //1、读取工作簿
        Workbook workbook = is03Excel ? new HSSFWorkbook(file.getInputStream()) : new XSSFWorkbook(file.getInputStream());
        //2、读取工作表
        Sheet sheet = workbook.getSheetAt(0);
        //3、读取行
        data.put("count", count);
        res.setResult("true");
        res.setData(data);
        res.setMessage("数据导入成功，本次导入" + count + "条数据");
        // workbook.close();
        file.getInputStream().close();
    } catch (Exception e) {
        data.put("count", count);
        res.setResult("false");
        res.setData(data);
        res.setMessage("数据导入失败，本次导入" + count + "条数据");
        e.printStackTrace();
    }
    return res;
}

2、上传类MultipartConfigFactory 设置

@Bean
    public MultipartConfigElement multipartConfigElement(){
        MultipartConfigFactory factory = new MultipartConfigFactory();
        //文件最大KB,MB
        factory.setMaxFileSize("10MB");
        //设置总上传数据总大小
        factory.setMaxRequestSize("15MB");
        return factory.createMultipartConfig();
    }

3、线上服务器报错：
