二:Java实现将Pdf转换为html

  1: 引入依赖

 1 <dependency>   2             <groupId>net.sf.cssbox</groupId>   3             <artifactId>pdf2dom</artifactId>   4             <version>1.7</version>   5         </dependency>    6         <dependency>   7             <groupId>org.apache.pdfbox</groupId>   8             <artifactId>pdfbox</artifactId>   9             <version>2.0.12</version>  10         </dependency>  11         <dependency>  12             <groupId>org.apache.pdfbox</groupId>  13             <artifactId>pdfbox-tools</artifactId>  14             <version>2.0.12</version>  15  </dependency>  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";   8     9        //try() 写在()里面会自动关闭流  10         try{  11             BufferedWriter out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(new File(outputHtmlPath)),"utf-8"));  12             //加载PDF文档  13             //PDDocument document = PDDocument.load(bytes);  14             PDDocument document = PDDocument.load(new File(inPdfPath));  15             PDFDomTree pdfDomTree = new PDFDomTree();  16             pdfDomTree.writeText(document,out);  17         } catch (Exception e) {  18             e.printStackTrace();  19         }  20     }  21   22     public static void main(String[] args) throws IOException {  23         PdfToHtml ph=new PdfToHtml();  24         String pdfPath="C:\works\files\武研中心行政考勤制度.pdf";  25         String outputPath="C:\works\files\武研中心行政考勤制度.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("&nbsp&nbsp&nbsp"+lineTxt + "</br>");  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     }
