java - 如何使用 apache POI 读取和替换书签值

Question

我是 apache POI 的完全新手，我已经尝试了几件事。我的问题是我在 docx 文件中有一些书签，我想替换它们的值。

到目前为止，我已经将文本添加到书签，但之前的值仍然存在

我的代码:

InputStream fis = new FileInputStream(fileName);
XWPFDocument document = new XWPFDocument(fis);
List<XWPFParagraph> paragraphs = document.getParagraphs();
for (XWPFParagraph paragraph : paragraphs)
{
    //Here you have your paragraph; 
    CTP ctp = paragraph.getCTP(); 
    // Get all bookmarks and loop through them 
    List<CTBookmark> bookmarks = ctp.getBookmarkStartList(); 
    for(CTBookmark bookmark : bookmarks) 
    { 
         if(bookmark.getName().equals("Firma1234"))
         {
             System.out.println(bookmark.getName());
             XWPFRun run = paragraph.createRun();
             run.setText(lcFirma);
                      ctp.getDomNode().insertBefore(run.getCTR().getDomNode(), bookmark.getDomNode());
         }
    }   
}
OutputStream out = new FileOutputStream(output);
document.write(out);
document.close();
out.close();    

“lcFirma”的值为“Firma”书签的值(value)是“测试标记”我之前的 docx 文件:

Testmark -> name=Firma1234

我的 docx 文件之后:

FirmaTestmark

就像我说的那样，文本插入到书签值之前而不是替换它，我该如何替换文本呢？

问候，

我也有类似的要求来设置 .docx 书签的“默认文本”字段。我无法这样做，所以，我这样做是为了解决这个问题:用文本替换了包含书签的整个段落。因此，我没有用默认文本填充书签，而是有一个包含书签文本的段落。在我的例子中，.docx 最终必须转换为 .pdf 文件，因此没有书签并不重要，但存在正确的文本更为重要。

这就是我用 Apache POI 做的:
