如何使用IText中的链接从一个页面导航到同一个PDF文件中的另一个页面？

Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("output.pdf"));
document.open();

// 添加需要导航的页面
document.add(new Paragraph("Page 1"));
document.newPage();
document.add(new Paragraph("Page 2"));

document.close();

PdfAction action = PdfAction.createGoTo("page2");

Anchor anchor = new Anchor("Go to Page 2", FontFactory.getFont(FontFactory.COURIER, 12, Font.UNDERLINE));
anchor.setAction(action);

Chunk chunk = new Chunk(anchor);

Paragraph paragraph = new Paragraph();
paragraph.add(chunk);

document.add(paragraph);

import com.itextpdf.text.*;
import com.itextpdf.text.pdf.*;

import java.io.FileOutputStream;

public class PdfLinkExample {
    public static void main(String[] args) {
        try {
            Document document = new Document();
            PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("output.pdf"));
            document.open();

            // 添加需要导航的页面
            document.add(new Paragraph("Page 1"));
            document.newPage();
            document.add(new Paragraph("Page 2"));

            // 创建导航链接
            PdfAction action = PdfAction.createGoTo("page2");
            Anchor anchor = new Anchor("Go to Page 2", FontFactory.getFont(FontFactory.COURIER, 12, Font.UNDERLINE));
            anchor.setAction(action);
            Chunk chunk = new Chunk(anchor);
            Paragraph paragraph = new Paragraph();
            paragraph.add(chunk);

            // 添加链接到PDF文档
            document.add(paragraph);

            document.close();
            writer.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
