二:Java实现将Pdf转换为html

  1: 引入依赖

 1 
 2             net.sf.cssbox
 3             pdf2dom
 4             1.7
 5          
 6         
 7             org.apache.pdfbox
 8             pdfbox
 9             2.0.12
10         
11         
12             org.apache.pdfbox
13             pdfbox-tools
14             2.0.12
15  
16

2:代码Demo

 1 public class PdfToHtml {
 2 
 3   /*
 4     pdf转换html
 5      */
 6     public void pdfToHtmlTest(String inPdfPath,String outputHtmlPath)  {
 7        // String outputPath = "C:\\works\\files\\ZSQ保密知识测试题库.html";

26         ph.pdfToHtmlTest(pdfPath,outputPath);
27   }
28 
29 }

三:Java实现将TXT转换为html

 1  /*
 2      * txt文档转html
 3        filePath:txt原文件路径
 4        htmlPosition:转化后生成的html路径
 5     */
 6     public static void txtToHtml(String filePath, String htmlPosition) {
 7         try {
 8             //String encoding = "GBK";
 9             File file = new File(filePath);
10             if (file.isFile() && file.exists()) { // 判断文件是否存在
11                 InputStreamReader read = new InputStreamReader(new FileInputStream(file), "GBK");
12                 // 考虑到编码格式
13                 BufferedReader bufferedReader = new BufferedReader(read);
14                 // 写文件
15                 FileOutputStream fos = new FileOutputStream(new File(htmlPosition));
16                 OutputStreamWriter osw = new OutputStreamWriter(fos, "GBK");
17                 BufferedWriter bw = new BufferedWriter(osw);
18                 String lineTxt = null;
19                 while ((lineTxt = bufferedReader.readLine()) != null) {
20                     bw.write("   "+lineTxt + "
");
21                 }
22                 bw.close();
23                 osw.close();
24                 fos.close();
25                 read.close();
26             } else {
27                 System.out.println("找不到指定的文件");
28             }
29         } catch (Exception e) {
30             System.out.println("读取文件内容出错");
31             e.printStackTrace();
32         }
33     }
