springbatch excel第二次不起作用

Question

我正在使用api来调用springbatch作业。当我第一次打电话它工作正常。第二次给出以下错误。

Caused by: java.lang.IllegalArgumentException: Sheet index (3) is out of range (0..2).

以下是我的代码.------------------------------------------ -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------

        //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()

        return "something";
    }
}

batch.properties：
