所需jar包和字体包链接：https://download.csdn.net/download/weixin_39530695/11390581
注意：压缩字体包（这个字体包包含常用字体，需要放到WEB-INF目录下）
这篇文章需要有一定基础：如果刚开始接触，请阅读详细的介绍：参考：https://blog.csdn.net/weixin_39530695/article/details/80432050

对于如何把word转换成html请参考这篇文章：
https://blog.csdn.net/weixin_39530695/article/details/96643166
如果必须得保证转换前后格式一致，建议采用这种方式：
