POI将word转化为html

参考资料

1.POI包依赖：https://poi.apache.org/components/index.html
2.包版本问题：https://bbs.csdn.net/topics/392208805 并没有使用其中的3.9的版本，使用的为3.13
最开始使用的为3.17的版本，但在转为成html中出现错误：java.lang.NoSuchMethodError，使用3.9版本也出现了类似的问题：
java.lang.NoSuchMethodError：org.apache.poi.POIXMLDocumentPart.getPackageRelationship()
3.整体的参考：http://www.cnblogs.com/always-online/p/4800131.html
4.在发布到服务器上时，图片路径问题标签的src：

相关说明：3.17版本在excel设置样式是API发生了变化
