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 {

      }
    } catch (ioexception e) {
      e.printstacktrace();
    } finally {
      try {
        zos.close();
        zin.closeentry();
        zin.close();
      } catch (ioexception e) {

      }
    }
  }
