我正在使用OdfToolkit读取 xls 文件和 odf 类型文件。以InputStream读取文件时出现异常。下面提供了我正在使用的阅读方法。
// store the file received in the server before processing
File file = new File("/path/to/stored-file-with-different-name");
multipartFile.transferTo(file);
FileInputStream fileInputStream = new FileInputStream(new File("stored-file-with-different-name");
SpreadsheetDocument.loadDocument(fileInputStream);
我得到的异常如下。

fileInputStream是由Spring引导中的MultipartFile文件构造而成的。
