试试这个。它对我有用。 setLocalGoto（）和 setLocalDestination（）将起到魔力。

Try this. It worked for me. setLocalGoto() and setLocalDestination() will do the magic.

Chunk chunk = new Chunk("Contact information");
    chunk.setLocalGoto("contact");  
    document.add(new Paragraph(chunk));
    document.newPage();

    chunk chunk1 = new Chunk("Contact information");
    chunk1.setLocalDestination("contact");
    Chapter chapter = new Chapter(new Paragraph(chunk1),1);    
    chapter.setNumberDepth(0);
    document.add(chapter);
