如何在 2021 年使用 Java 将 docx 文件转换为 PDF？

Question

I'm trying to convert docx files into PDF with Java in Windows OS. All the alternatives that I found seems to be deprecated or there are not compatibilities between libraries. For example I found that apache poi can convert docx into PDF but the solutions I found are from 10 years ago.

Also I found documents4j , but the same problem: I get a lot of exceptions.

is there some simple way to do the conversion?.

Or what libraries are currently working to perform the conversion?
