Java 如何用ApachePOI读取和替换书签值

我是ApachePOI的完全新手，我已经尝试过几种方法。我的问题是docx文件中有几个书签，我想替换它们的值

我已经将文本添加到书签中，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();    

我的docx文件在以下时间之后：

FirmaTestmark

就像我说的，文本插入到书签值之前，而不是替换它，我如何替换文本

您好

试试下面的代码

private List<XWPFParagraph> collectParagraphs()
    {
        List<XWPFParagraph> paragraphs = new ArrayList<>();
        paragraphs.addAll(this.document.getParagraphs());

        for (XWPFTable table : this.document.getTables())
        {
            for (XWPFTableRow row : table.getRows())
            {
                for (XWPFTableCell cell : row.getTableCells())
                    paragraphs.addAll(cell.getParagraphs());
            }
        }
        return paragraphs;
    }

    public List<String> getBookmarkNames()
    {
        List<String> bookmarkNames = new ArrayList<>();
        Iterator<XWPFParagraph> paraIter = null;
        XWPFParagraph para = null;
        List<CTBookmark> bookmarkList = null;
        Iterator<CTBookmark> bookmarkIter = null;
        CTBookmark bookmark = null;
        XWPFRun run = null;

        // Get an Iterator for the XWPFParagraph object and step through them
        // one at a time.
        paraIter = collectParagraphs().iterator();
        while (paraIter.hasNext())
        {
            para = paraIter.next();

            // Get a List of the CTBookmark object sthat the paragraph
            // 'contains' and step through these one at a time.
            bookmarkList = para.getCTP().getBookmarkStartList();
            bookmarkIter = bookmarkList.iterator();
            while (bookmarkIter.hasNext())
            {
                bookmark = bookmarkIter.next();
                bookmarkNames.add(bookmark.getName());
            }
        }
        return bookmarkNames;
    }

我还需要设置.docx书签的默认文本字段。我不能这样做，所以，我这样做是为了解决问题：用文本替换包含书签的整个段落。因此，我没有用默认文本填充书签，而是用一个段落来保存书签文本。在我的例子中，.docx最终必须转换成一个.pdf文件，因此没有书签并不重要，但正确文本的存在更重要

我是误读了什么，还是你的代码只是得到了所有的书签名？替换书签值的部分在哪里？
