注：这里只能转换docx文件，doc不行，源码在文末。 可以在windows，linux上运行，增加了内容替换功能，因为有些文档内容需要我们用代码来动态生成。 下面是具体操作步骤： maven依赖 org.apache.poi poi-scratchpad 3.11 org.apache.poi ooxml-schemas 1.1 com.itextpdf itextpdf 5.4.3 fr.opensagres.xdocreport org.apache.poi.xwpf.converter.pdf 1.0.6 fr.opensagres.xdocreport org.apache.poi.xwpf.converter.xhtml 1.0.6 org.docx4j docx4j-ImportXHTML 3.2.0 java代码 package com.gitee.docx2pdf;
