Java word转为html 两种方式
废话不多说直接上代码！
·
滴滴滴上重点。。。
方式一：使用apache提供的工具包poi，poi使用的是4.1.2版本
缺点：对字体样式处理不精确；wmf公式图片部分转换不精确，本文档只支持doc格式
优点：转换速度相对很快，本地也方便调试
方式二：使用libreoffice，使用的是7.5版本
地址：下载 LibreOffice | LibreOffice 简体中文官方网站 - 自由免费的办公套件
Linux安装libreoffice案例：linux centos7工具安装之 libreOffice篇 libreOffice安装教程_centos7 安装libreoffice_the_bog的博客-CSDN博客
缺点：转换速度相对慢
优点：字体样式十分精确，本文档只支持doc，docx等等。转换pdf等相关命令百度获取
废话不多说直接上代码！！！
方式一代码实现：
