二:Java实现将Pdf转换为html

1: 引入依赖

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("   "+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     }
