html转pdf pd4ml

本文介绍了一种将HTML代码直接转换为PDF文件的方法,无需使用浏览器插件。通过Java程序实现,利用pd4ml等库完成转换过程。

    直接把html代码转化成pdf文件,不需要调用插件

    直接上代码

    

public void Conversion(File file , String outputPath ) throws Exception{
    int topValue = 10;  
    int leftValue = 10;  
    int rightValue = 10;  
    int bottomValue = 10;  
    int userSpaceWidth = 800; 
    PD4ML pd4ml = new PD4ML();
    
    pd4ml.setHtmlWidth(userSpaceWidth);
  
    pd4ml.setPageSize(PD4Constants.A4);//pd4ml.changePageOrientation()
  
    pd4ml.setPageInsetsMM(new Insets(topValue, leftValue, bottomValue, rightValue));
  
    //pd4ml.addStyle("BODY {margin: 500}", true);
  
    pd4ml.useTTF("java:fonts", true);
    pd4ml.setDefaultTTFs("SimHei", "SimHei", "SimHei"); 
    pd4ml.enableDebugInfo();
    FileInputStream in = new FileInputStream(file);
    InputStreamReader is = new InputStreamReader(in);
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    pd4ml.render(is, baos);
    baos.close();  
  
    System.out.println( "resulting PDF size: " + baos.size() + " bytes" );  
  
    File output = new File(outputPath);
    FileOutputStream fos = new FileOutputStream(output);  
      fos.write( baos.toByteArray() );
      fos.close();  
  
      System.out.println( outputPath + "\ndone." );
  }

    只需要传入源文件,以后输出路径即可,需要的jar:pd4ml.jar; font.jar; ss_css2.jar; 点击下载

    (font.jar一般不支持中文字体,需要自己修改jar包里面的配置文件)

1、解决中文问题 2、附字体 3、动态html拼接pdf public static void htmlCodeComeString(String linkcss,String htmlCode, String outputFile,String title) throws Exception { OutputStream os = new FileOutputStream(outputFile); ITextRenderer renderer = new ITextRenderer(); renderer.setDocumentFromString(getConversionHtmlCode(linkcss,htmlCode,title)); ITextFontResolver fontResolver = renderer.getFontResolver(); URL fontPath = ItextUtil.class.getResource("simsun.ttc"); fontResolver.addFont(fontPath.toString(), BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); // 解决图片的相对路径问题 // renderer.getSharedContext().setBaseURL("file:/F:/teste/html/"); renderer.layout(); renderer.createPDF(os); System.out.println("======换成功!"); os.close(); os.flush(); } public static void main(String[] args) { ItextUtil itextUtil = new ItextUtil(); String html = ""; html += ""; html += "企业信息"; html += " "; html += " "; html += " 登记日期"; html += " 2006-04-28"; html += " "; html += " "; html += " 纳税人编号"; html += " HSJIHKS002"; html += " "; html += " "; html += " 有效标志"; html += " Y"; html += " "; html += " "; html += " 社会信用代码"; html += " 916101317H"; html += " "; html += " "; html += " 评估机关代码"; html += " 盛世"; html += " "; html += " "; html += " 工商注销日期"; html += " 2006-04-28"; html += " "; html += " "; html += ""; String outputFile = "D:\\pdf\\aa.pdf"; try { itextUtil.htmlCodeComeString("",html,outputFile,""); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } System.out.println("生成结束!!!"); }
