我尝试通过将 .xlsx 作为资源流传递来使用 Apache-POI 创建 xlsx 工作簿对象:
Workbook workbook = WorkbookFactory.create(RFQGenerator.class.getResourceAsStream("/com/lumos/xlsx_manager/es/da/template.xlsx"));
通过 FileInputStream 和本地文件路径传递 template.xlsx 时，我可以成功实例化工作簿，但是当我传递资源流时，出现异常:

我传递的 .xlsx 不应被压缩，但也许这就是它与资源流一起工作的方式。关于如何通过资源访问将文件传递到 Apache-POI 有什么想法吗？
最佳答案
事实证明，使用 Maven 资源时必须取消过滤二进制文件。
Maven corrupting binary files in source/main/resources when building jar
关于java - 'ZipException : invalid code lengths set' when streaming input file to Apache-POI，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/47011240/
