How to add hyperlink in pdf using pdfbox

问题

I want to add a hyperlink in PDF created using PDFBOX, such that i click on some text example 'Click here' will redirect to URL. I tried using PDAnnotationLink and PDActionURI, but how to add it in contentstream?

PDBorderStyleDictionary borderULine = new PDBorderStyleDictionary();
borderULine.setStyle(PDBorderStyleDictionary.STYLE_UNDERLINE);
PDAnnotationLink txtLink = new PDAnnotationLink();
txtLink.setBorderStyle(borderULine);
txtLink.setColour(colourBlue);

// add an action
PDActionURI action = new PDActionURI();
action.setURI("www.google.com");
txtLink.setAction(action);

contentStream.beginText();
contentStream.moveTextPositionByAmount(400, y-30);
contentStream.drawString(txtLink);----error
contentStream.endText();

回答1:

To add to contentStream use the following code

    PDRectangle position = new PDRectangle();
    position.setLowerLeftX(10);
    position.setLowerLeftY(20); 
    position.setUpperRightX(100); 
    position.setUpperRightY(10); 
    txtLink.setRectangle(position);
    page.getAnnotations().add(txtLink);

There is a library called PDFBox-Layout which makes it easier to add hyperlinks:

Document document = new Document();

Paragraph paragraph = new Paragraph();
paragraph.addMarkup(
   "This is a link to {link[https://github.com/ralfstuckert/pdfbox-layout]}PDFBox-Layout{link}",
 18f, BaseFont.Helvetica);
document.add(paragraph);

final OutputStream outputStream = new FileOutputStream("link.pdf");
document.save(outputStream);
