Using Flying Saucer API with iText PDF you can convert HTML content to PDF.
Following examples help you in understanding, to some extent, conversion of XHTML to PDF.

使用带有iText PDF的飞碟API，您可以将HTML内容转换为PDF。以下示例在某种程度上帮助您理解XHTML到PDF的转换。

Examples Using Flying Saucer API:
You require following libraries:

使用飞碟API的示例:您需要以下库:

core-renderer.jar
core-renderer.jar
iText-2.0.8.jar
iText-2.0.8.jar

You can find these resources in flyingsaucer-R8.zip.

你可以在flyingsaucer-R8.zip中找到这些资源。

Example1: Using XML Resource:

例二:使用XML资源:

// if you have html source in hand, use it to generate document object
Document document = XMLResource.load( new ByteArrayInputStream( yourXhtmlContentAsString.getBytes() ) ).getDocument();

ITextRenderer renderer = new ITextRenderer();
renderer.setDocument( document, null );

renderer.layout();

String fileNameWithPath = outputFileFolder + "PDF-XhtmlRendered.pdf";
FileOutputStream fos = new FileOutputStream( fileNameWithPath );
renderer.createPDF( fos );
fos.close();
System.out.println( "File 1: '" + fileNameWithPath + "' created." );

Example2: Using XHTML direct input to Document:

示例2:使用XHTML直接输入文档:

ITextRenderer renderer = new ITextRenderer();

// if you have html source in hand, use it to generate document object
renderer.setDocumentFromString( yourXhtmlContentAsString );
renderer.layout();

String fileNameWithPath = outputFileFolder + "PDF-FromHtmlString.pdf";
FileOutputStream fos = new FileOutputStream( fileNameWithPath );
renderer.createPDF( fos );
fos.close();

System.out.println( "File 2: '" + fileNameWithPath + "' created." );

Examples Using iText API:
You require following libraries:

使用iText API的示例:您需要以下库:

core-renderer.jar
core-renderer.jar
itextpdf-5.2.1.jar
itextpdf-5.2.1.jar

You can find these resources at here.

你可以在这里找到这些资源。

Example3: Using HTML Worker:

青年们:使用HTML工作人员:

com.itextpdf.text.Document document =
        new com.itextpdf.text.Document( com.itextpdf.text.PageSize.A4 );
String fileNameWithPath = outputFileFolder + "PDF-HtmlWorkerParsed.pdf";
FileOutputStream fos = new FileOutputStream( fileNameWithPath );
com.itextpdf.text.pdf.PdfWriter pdfWriter =
        com.itextpdf.text.pdf.PdfWriter.getInstance( document, fos );

document.open();

//**********************************************************
// if required, you can add document meta data
document.addAuthor( "Ravinder" );
//document.addCreator( creator );
document.addSubject( "HtmlWoker Parsed Pdf from iText" );
document.addCreationDate();
document.addTitle( "HtmlWoker Parsed Pdf from iText" );
//**********************************************************/

com.itextpdf.text.html.simpleparser.HTMLWorker htmlWorker =
        new com.itextpdf.text.html.simpleparser.HTMLWorker( document );
htmlWorker.parse( new StringReader( sb.toString() ) );

document.close();
fos.close();

System.out.println( "File 3: '" + fileNameWithPath + "' created." );

You can use JTidy framework for this. This will convert HTML to XHTML and translate again to XSL-FO. This object can be used for generating PDF.

您可以为此使用JTidy框架。这将把HTML转换为XHTML并再次转换为XSL-FO。此对象可用于生成PDF。
