当我提取使用 docx4j 实现生成的 excel 时，我可以在下面看到额外的命名空间:

我如何删除它？

Excel size decreases on resaving using docx4j library implementation
最佳答案
尝试使用 MOXy，或设置属性 docx4j.jaxb.marshal.canonicalize=true
来自 https://github.com/plutext/docx4j/blob/master/docx4j-samples-resources/src/main/resources/docx4j.properties#L160
# Whether to canonicalize during marshalling (defaults to false).
# This is mainly for aesthetic purposes: the Sun/Oracle JAXB reference implementation
# writes a lot of unnecessary namespaces (each one in the JAXB context?). MOXy is better.
# Set this to true to get rid of them via an extra step: canonicalization
# since docx4j 3.3.1
docx4j.jaxb.marshal.canonicalize=false
