使用忠告
使用该方式进行xhtml到word的转换, 简单转换是可以, 但是可能并没有想象中那么满意, 转换出来的word格式并不完美, 比如目录和标题都会丢失, 标题显示看起来一样, 但是是用正文加粗和加大字号来显示的. 毕竟word是一种文档格式, 而html是一种标记性语言, 要想实现完美兼容和转换很难
加上word与html互转(1) -- word转html, 虽然word与html互转都有实现手段, 但是考虑到转换的格式复杂度和后期的维护成本, 我们最后放弃去实现这个成本高但是对项目影响不大的功能
实现
实现方式
使用poi+xdocreport来实现
poi:都熟悉, 这边不作介绍
Docx4j:是github上的一个开源项目, 使用起来很简单, 可以很轻松的将xhtml转为docx, 他的具体介绍可以去他的项目地址查看--项目地址
