替换docx文件里面的 ${} 字符串

public class Main {
  public static void main(String[] args) throws Exception {
  String template = "C:\\Users\\lzh\\Desktop\\模板.docx";
  String outSrc = "C:\\Users\\lzh\\Desktop\\简历.docx";
 
  var is = new FileInputStream(template);
  var os = new FileOutputStream(outSrc);
 
  editDocx(os, is, xml -> {
    Map<String,String> map = new HashMap<>();
    map.put("${name}", "李**");
    map.put("${sex}", "男");
    map.put("${age}", "21");
 
    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;
  });
  }
 
  public static void editDocx(OutputStream bos,InputStream is, Process process){
  ZipInputStream zin = new ZipInputStream(is);
  ZipOutputStream zos = new ZipOutputStream(bos);
  try {
    ZipEntry entry;
    while((entry = zin.getNextEntry()) != null) {
    //把输入流的文件传到输出流中 如果是word/document.xml由我们输入
    zos.putNextEntry(new ZipEntry(entry.getName()));
    if("word/document.xml".equals(entry.getName())){
      String xml = new BufferedReader(new InputStreamReader(zin)).lines().collect(Collectors.joining(System.lineSeparator()));
      xml = process.process(xml);
 
      ByteArrayInputStream byteIn = new ByteArrayInputStream(xml.getBytes());
      int c;
      while ((c = byteIn.read()) != -1) {
      zos.write(c);
      }
      byteIn.close();
    }else {
      int c;
      while ((c = zin.read()) != -1) {
      zos.write(c);
      }
    }
    }
  } catch (IOException e) {
    e.printStackTrace();
  } finally {
    try {
    zos.close();
    zin.closeEntry();
    zin.close();
    } catch (IOException e) {
    e.printStackTrace();
    }
  }
  }
}
 
interface Process {
  String process(String xml);
}
