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

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
public class PdfToHtml {
/*
pdf转换html
*/
public void pdfToHtmlTest(String inPdfPath,String outputHtmlPath) {
// String outputPath = "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{
BufferedWriter out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(new File(outputHtmlPath)),"utf-8"));
//加载PDF文档
//PDDocument document = PDDocument.load(bytes);
PDDocument document = PDDocument.load(new File(inPdfPath));
PDFDomTree pdfDomTree = new PDFDomTree();
pdfDomTree.writeText(document,out);
} catch (Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) throws IOException {
PdfToHtml ph=new PdfToHtml();
String pdfPath="C:\\works\\files\\武研中心行政考勤制度.pdf";
String outputPath="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
*/
public static void txtToHtml(String filePath, String htmlPosition) {
try {
//String encoding = "GBK";
File file = new File(filePath);
if (file.isFile() && file.exists()) { // 判断文件是否存在
InputStreamReader read = new InputStreamReader(new FileInputStream(file), "GBK");
// 考虑到编码格式
BufferedReader bufferedReader = new BufferedReader(read);
// 写文件
FileOutputStream fos = new FileOutputStream(new File(htmlPosition));
OutputStreamWriter osw = new OutputStreamWriter(fos, "GBK");
BufferedWriter bw = new BufferedWriter(osw);
String lineTxt = 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 (Exception e) {
System.out.println("读取文件内容出错");
e.printStackTrace();
}
}
