Today, I found that there is a problem with the previous import, which only supports 2003, and does not support 2007 and above. poi is all the current excel support
version. It's just that the reading method names used by different versions are different.
I also found that many blog posts on the Internet are unjudged versions, including the articles I borrowed from before.
