如何使用springbatch从xls导入mysql数据库？

Question

我正在尝试创建一个接收.xlsx文件作为输入的api。文件中的数据导入mysql数据库。已经完成了一些教程。能够在硬编码文件路径时使其完美运行，并且一旦服务器启动，它就会成功执行。但是，当我尝试从用户和进程接收文件时，我收到错误。此外，我没有找到相同的资源。

以下是我的代码和错误。

@Controller
public class FileController1 {

    @Autowired 
    private JobLauncher jobLauncher;

    @Autowired 
    private Job importUserJob;

    @Autowired 
    public JobBuilderFactory jobBuilderFactory;

    @Autowired
    public StepBuilderFactory stepBuilderFactory;

    ExcelFileToDatabaseJobConfig excelFileToDatabaseJobConfig;


    @Bean
    ItemReader<StudentDTO> excelStudentReader(@Value("#{jobParameters[fullPathFileName]}") String pathToFile) throws Exception{
        System.out.println("inside excelStudentReader");
        PoiItemReader<StudentDTO> reader = new PoiItemReader<>();
        reader.setLinesToSkip(1);
        reader.setResource(new ClassPathResource(pathToFile));
        //reader.setResource(new UrlResource("file:///D:/joannes/ee.xlsx"));
        reader.setRowMapper(excelRowMapper());
        return reader;
    }
    private RowMapper<StudentDTO> excelRowMapper() {
        System.out.println("inside excelRowMapper");
        BeanWrapperRowMapper<StudentDTO> rowMapper = new BeanWrapperRowMapper<>();
        rowMapper.setTargetType(StudentDTO.class);
        return rowMapper;
    }

        */

        String path = new ClassPathResource("/").getURL().getPath();//it's assumed you have a folder called tmpuploads in the resources folder
        File fileToImport = new File(path + multipartFile.getOriginalFilename());
        //filePath = fileToImport.getAbsolutePath();
        OutputStream outputStream = new FileOutputStream(fileToImport);
        IOUtils.copy(multipartFile.getInputStream(), outputStream);
        outputStream.flush();
        outputStream.close();
        //Launch the Batch Job
        JobExecution jobExecution = jobLauncher.run(importUserJob,new JobParametersBuilder()
                .addString("fullPathFileName", fileToImport.getAbsolutePath()).toJobParameters());
        //return map;
        return "something";
    }
}

错误：
