如何使用Apache POI将超链接添加到XWPFDocument的页脚？

import org.apache.poi.xwpf.usermodel.*;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.*;
import org.apache.xmlbeans.XmlCursor;

XWPFDocument document = new XWPFDocument();

CTSectPr sectPr = document.getDocument().getBody().addNewSectPr();
XWPFHeaderFooterPolicy policy = new XWPFHeaderFooterPolicy(document, sectPr);
XWPFFooter footer = policy.createFooter(XWPFHeaderFooterPolicy.DEFAULT);
XWPFParagraph paragraph = footer.createParagraph();

CTHyperlink link = paragraph.getCTP().addNewHyperlink();
link.setAnchor("http://www.example.com"); // 设置超链接的目标URL

CTR ctr = link.addNewR();
CTRPr rPr = ctr.addNewRPr();
CTUnderline underline = rPr.addNewU();
underline.setVal(STUnderline.SINGLE); // 设置超链接下划线样式

CTRPr ctrPr = paragraph.getCTP().addNewR().addNewRPr();
ctrPr.setRStyle(rStyle); // 设置超链接样式

CTR run = paragraph.getCTP().addNewR();
run.setTArray(new CTText[]{CTText.Factory.newInstance()});
run.getTArray(0).setStringValue("Link Text"); // 设置超链接文本

FileOutputStream out = new FileOutputStream("output.docx");
document.write(out);
out.close();
