java io流读取多个文件写进zip文件(zip文件夹可自定义,满足特定的需求)

代码如下

public static void main(String[] args) throws Exception {
        FileOutputStream fos = new FileOutputStream("d:/opt/xbpm/upload/aa.zip");
        Map<String, byte[]> datas = new HashMap<>();
        datas.put("a/file1.pdf", FileUtil.readBytes("d:/opt/xbpm/upload/2021/1201/429476510253187073.pdf"));

        ZipOutputStream zipOut = new ZipOutputStream(new BufferedOutputStream(fos));

        for (Map.Entry<String, byte[]> date : datas.entrySet()) {
            zipOut.putNextEntry(new ZipEntry(date.getKey()));
            zipOut.write(date.getValue());
        }
        zipOut.close();

    }

需要实现一个对选择的工单附件进行导出(附件文件夹名按照“工单名称”或者“工单编号分类”),可是实际服务器存放的附件方式是:年月日+随机名称.pdf
