二:Java实现将Pdf转换为html
1: 引入依赖
12 6net.sf.cssbox 3pdf2dom 41.7 57 11org.apache.pdfbox 8pdfbox 92.0.12 1012 16org.apache.pdfbox 13pdfbox-tools 142.0.12 15
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 }
