java 替换docx文件中的字符串方法实现

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);
}
