Java 如何使用ApachePOI向XWPFDocument的页脚添加超链接?
Java 如何使用ApachePOI向XWPFDocument的页脚添加超链接?,java,hyperlink,apache-poi,footer,xwpf,Java,Hyperlink,Apache Poi,Footer,Xwpf,appendExternalHyperlink()方法在XWPFDocument的页脚中不起作用。在页脚中,结果不会被识别为超链接 我是ApachePOI新手,对低级的东西没有经验。有人能解释一下这里有什么问题吗 public class FooterProblem { public static void main(final String[] args) throws Exception { final XWPFDocument docx = new XWPFDocument
appendExternalHyperlink()

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。它总是使用段落.getDocument()
。这是错误的
以下代码提供了一种方法,用于在给定的XWPFParagraph
中创建XWPFHyperlinkRun
,并获取正确的包部分以将关系置于其上。它使用段落.getPart()
获取正确的部分。因此,此方法适用于文档正文以及页眉和/或页脚中的段落

非常感谢您立即回复。如果我想了解更多关于ApachePOI-XWPF的信息,尤其是了解底层代码的好起点是什么?@Martin:下载源代码并从中执行
javadoc
。ooxml模式
是从officeopenxml
规范生成的类。因此,如果您解压缩*.docx
文件并查看/word/document.XML
或/word/footer1.XML
,这些类对应于您得到的XML
元素。这些提示对我非常有用!谢谢。
