如何使用 Apache POI 将超链接添加到 XWPFDocument 的页脚?
How to add a hyperlink to the footer of a XWPFDocument using Apache POI?
appendExternalHyperlink()
方法 (source) 在 XWPFDocument 的页脚中不起作用。在页脚中,结果未被识别为超链接。
我是 Apache POI 的新手,对底层的东西没有任何经验。有人可以解释一下这里的问题吗?
public class FooterProblem {
public static void main(final String[] args) throws Exception {
final XWPFDocument docx = new XWPFDocument();
final XWPFParagraph para = docx.createParagraph();
final XWPFRun paraRun = para.createRun();
paraRun.setText("Email: ");
appendExternalHyperlink("mailto:me@example.com", "me@example.com", para);
final XWPFParagraph footer = docx.createFooter(HeaderFooterType.DEFAULT).createParagraph();
final XWPFRun footerRun = footer.createRun();
footerRun.setText("Email: ");
appendExternalHyperlink("mailto:me@example.com", "me@example.com", footer);
final FileOutputStream out = new FileOutputStream("FooterProblem.docx");
docx.write(out);
out.close();
docx.close();
}
public static void appendExternalHyperlink(final String url, final String text, final XWPFParagraph paragraph) {
// Add the link as External relationship
final String id = paragraph.getDocument().getPackagePart()
.addExternalRelationship(url, XWPFRelation.HYPERLINK.getRelation()).getId();
// Append the link and bind it to the relationship
final CTHyperlink cLink = paragraph.getCTP().addNewHyperlink();
cLink.setId(id);
// Create the linked text
final CTText ctText = CTText.Factory.newInstance();
ctText.setStringValue(text);
final CTR ctr = CTR.Factory.newInstance();
ctr.setTArray(new CTText[] { ctText });
// Insert the linked text into the link
cLink.setRArray(new CTR[] { ctr });
}
}
footer[n].xml
是它自己的包部分,需要它自己的关系。但是您的代码总是为 document.xml
包部分创建外部超链接关系。它总是使用 paragraph.getDocument()
。这是错误的。
以下代码提供了一种在给定 XWPFParagraph
中创建 XWPFHyperlinkRun
并获取正确的包部分以放置关系的方法。它使用 paragraph.getPart()
来获得正确的部分。因此,此方法适用于文档正文中的段落以及页眉 and/or 页脚中的段落。
