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,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

二:Java实现将Pdf转换为html
1:引入依赖
net.sf.cssbox pdf2dom 1.7 org.apache.pdfbox pdfbox 2.0.12 org.apache.pdfbox pdfbox-tools 2.0.12
2:代码Demo
publicclassPdfToHtml{
/*
pdf转换html
*/
publicvoidpdfToHtmlTest(StringinPdfPath,StringoutputHtmlPath){
//StringoutputPath="C:\\works\\files\\ZSQ保密知识测试题库.html";
//try()写在()里面会自动关闭流
try{
BufferedWriterout=newBufferedWriter(newOutputStreamWriter(newFileOutputStream(newFile(outputHtmlPath)),"utf-8"));
//加载PDF文档
//PDDocumentdocument=PDDocument.load(bytes);
PDDocumentdocument=PDDocument.load(newFile(inPdfPath));
PDFDomTreepdfDomTree=newPDFDomTree();
pdfDomTree.writeText(document,out);
}catch(Exceptione){
e.printStackTrace();
}
}
publicstaticvoidmain(String[]args)throwsIOException{
PdfToHtmlph=newPdfToHtml();
StringpdfPath="C:\\works\\files\\武研中心行政考勤制度.pdf";
StringoutputPath="C:\\works\\files\\武研中心行政考勤制度.html";
ph.pdfToHtmlTest(pdfPath,outputPath);
}
}
三:Java实现将TXT转换为html
/*
*txt文档转html
filePath:txt原文件路径
htmlPosition:转化后生成的html路径
*/
publicstaticvoidtxtToHtml(StringfilePath,StringhtmlPosition){
try{
//Stringencoding="GBK";
Filefile=newFile(filePath);
if(file.isFile()&&file.exists()){//判断文件是否存在
InputStreamReaderread=newInputStreamReader(newFileInputStream(file),"GBK");
//考虑到编码格式
BufferedReaderbufferedReader=newBufferedReader(read);
//写文件
FileOutputStreamfos=newFileOutputStream(newFile(htmlPosition));
OutputStreamWriterosw=newOutputStreamWriter(fos,"GBK");
BufferedWriterbw=newBufferedWriter(osw);
StringlineTxt=null;
while((lineTxt=bufferedReader.readLine())!=null){
bw.write(""+lineTxt+"");
}
bw.close();
osw.close();
fos.close();
read.close();
}else{
System.out.println("找不到指定的文件");
}
}catch(Exceptione){
System.out.println("读取文件内容出错");
e.printStackTrace();
}
}
