                    if (bookTagMap.containsKey(bookmark.getName())) {
    
                        XWPFRun run = xwpfParagraph.createRun();
                        run.setText(bookTagMap.get(bookmark.getName()).toString());
    
                        Node firstNode = bookmark.getDomNode();
                        Node nextNode = firstNode.getNextSibling();
                        while (nextNode != null) {
                            // 循环查找结束符
                            String nodeName = nextNode.getNodeName();
                            if (nodeName.equals("w:bookmarkEnd")) {
                                break;
                            }
    
                            // 删除中间的非结束节点，即删除原书签内容
                            Node delNode = nextNode;
                            nextNode = nextNode.getNextSibling();
    
                            ctp.getDomNode().removeChild(delNode);
                        }
    
                        if (nextNode == null) {
                            // 始终找不到结束标识的，就在书签前面添加
                            ctp.getDomNode().insertBefore(run.getCTR().getDomNode(), firstNode);
                        } else {
                            // 找到结束符，将新内容添加到结束符之前，即内容写入bookmark中间
                            ctp.getDomNode().insertBefore(run.getCTR().getDomNode(), nextNode);
                        }

                }

         * @param response
         */
        @GetMapping("/replaceBookTag")
        public void replaceBookTag(HttpServletResponse response) {
            try {
                //读文件
                ClassPathResource cpr = new ClassPathResource("/doc/模板.docx");
                XWPFDocument document = new XWPFDocument(cpr.getInputStream());
    
                //书签数据
                Map<String, Object> bookTagMap = new HashMap<>();
                bookTagMap.put("xudongmaster", "旭东怪");
                bookTagMap.put("xudongmaster2", "旭东怪2");
    
                replaceBookTag(document,bookTagMap);
    
                //返回流
                response.setHeader("content-type", "application/octet-stream");

                OutputStream outputStream = response.getOutputStream();
                document.write(outputStream);
                outputStream.flush();

### 注： ###

（1）出现书签替换失败的情况时，解决办法参考以下博客。

[POI XWPFParagraph.getRuns分段混乱问题解决][POI XWPFParagraph.getRuns]

（2）该书签替换功能有两个问题，第一个是样式会修改，第二个是不支持表格内的书签替换。想要实现完美的文字替换效果请参考以下这篇博客。
