java 替换docx文件中的字符串方法实现

public class Main {
  public static void main(String[] args) throws Exception {
    String template = "C:\\Users\\lzh\\Desktop\\模板.docx";

      Pattern p = Pattern.compile("(\\$\\{)([\\w]+)(\\})");
      Matcher m = p.matcher(xml);
      StringBuffer sb = new StringBuffer();
      while (m.find()) {
        String group = m.group();
        m.appendReplacement(sb, map.get(group));
      }
      m.appendTail(sb);
      xml = sb.toString();

      return xml;
