Java实现Word/Pdf/TXT转html的实例代码

引言:

最近公司在做一个教育培训学习及在线考试的项目,本人主要从事网络课程模块,主要做课程分类,课程,课件的创建及在线学习和统计的功能,因为课件涉及到多种类型,像视频,音频,图文,外部链接及文档类型.其中就涉及到一个问题,就是文档型课件课程在网页上的展示和学习问题,因为要在线统计学习的课程,学习的人员cgHASaIji,学习的时长,所以不能像传统做法将文档下载到本地学习,那样就不受系统控制了,所以最终的方案是,在上传文档型课件的时候,将其文件对应的转换成HTML文件,以便在网页上能够浏览学习

下边主要针对word,pdf和txt文本文件进行转换

一:java实现将word转换为html

1:引入依赖

//加载PDF文档

//PDDocument document = PDDocument.load(bytes);

PDDocument document = PDDocument.load(new File(inPdfPath));
