用Java中的Apache POI生成文档间超链接 | 码农家园
我正在用Apache POI生成XWPFDocument(在此之前从未使用过)，并且我想将一个段落链接到同一.docx文档中的另一段落。是否可以使用POI的本机功能，还是我需要深入研究XML Bean包装器类(即CTP)来对此进行干扰？还是我不走运？我所看到的有关超链接和POI的每个问题实例都引用了创建外部类型的超链接或Excel工作簿工作表之间的链接的信息。到目前为止，我只能按ctrl键单击完成的文档中的段落来生成"超链接"，并且似乎只是从文档顶部开始进行文本搜索。这是我目前用于实现此目的的代码。在此先感谢您！

public static void addInternalHyperlink(XWPFParagraph origin, String text, XWPFParagraph target) {
if (target != null) {
// Create the hyperlink itself
CTHyperlink link = origin.getCTP().addNewHyperlink();
link.setAnchor(target.getText());
// Create hyperlink text
CTText linkText = CTText.Factory.newInstance();
linkText.setStringValue(text);
CTR ctr = CTR.Factory.newInstance();
ctr.setTArray(new CTText[] {linkText});
// Format hyperlink text
CTFonts fonts = CTFonts.Factory.newInstance();
fonts.setAscii("Times New Roman");
CTRPr rpr = ctr.addNewRPr();
CTColor color = CTColor.Factory.newInstance();
color.setVal("0000FF");
rpr.setColor(color);
CTRPr rpr1 = ctr.addNewRPr();
rpr1.addNewU().setVal(STUnderline.SINGLE);
// Insert formatted text into link
link.setRArray(new CTR[] {ctr});
}
}
请注意，我想使用" origin"自变量作为包含实际链接的段落，将" text"自变量作为链接文本，并使用" target"参数作为实际的链接目标。
更新：这是一个XML代码段，其中包含一个示例段落，我已通过Word GUI将其链接到节标题。

- 如何做取决于应使用哪种超链接。您将如何在Words GUI中执行此操作？请参阅support.microsoft.com/zh-cn/help/291182/-> "如何创建指向同一文档中位置的超链接？"。执行其中一项，然后查看*.docx ZIP存档中生成的XML。
- 我希望生成类似于"插入超链接->放置在此文档中"操作的超链接，通过该超链接，文本的任何部分都可以指向同一文档中的节标题(甚至更好的是，可以指向任何文档中的节标题)。段)。我可以访问生成的XML，但是我不确定如何在Java中访问和设置这些字段。
- 我更新了问题，以包含一个包含原始段落和目标段落的XML代码段。

解决方案分为两部分。
首先我们需要一个XWPFHyperlinkRun，其目标是文档中的锚点。
其次，我们需要该目标锚点，例如，它可以是文档中的书签。因此，我们需要在文档中创建这样的书签。不幸的是，到目前为止，仅使用apache poi的高级类才支持这两种书签。因此，我们也需要使用ooxml-schemas形式的低级类。
以下代码将apache poi 4.0.0与ooxml-schemas-1.4一起使用。
