我正在使用 Apache poi Maven，版本 3.9

注1:为了正确释放资源，Workbook 使用后应关闭.

Note 1: that in order to properly release resources the Workbook should be closed after use.

注意 2:从 InputStream 加载比从文件加载需要更多内存

您需要关闭工作簿，而不是它的工厂.

You need to close the Workbook, not its factory.

注意 1:为了正确释放资源，Workbook 使用后应关闭.

Note 1: that in order to properly release resources the Workbook should be closed after use.

正确.

注意 2:从 InputStream 加载比从 File

Note 2: also that loading from an InputStream requires more memory than loading from a File

不真实，除非 InputStream 是 ByteArrayInputStream.

Untrue, unless the InputStream is a ByteArrayInputStream.
