使用hutool实现压缩zip到输出流(包括空zip)

//将文件直接压缩至输出流
String[] fileNames = fileNameList.toArray(new String[0]);
InputStream[] inputStreams = inputStreamList.toArray(new InputStream[0]);
if (ArrayUtil.isNotEmpty(fileNames)) {
    //输出压缩文件到指定的输出流
    ZipUtil.zip(outputStream, fileNames, inputStreams);
} else {
    //输出空zip到指定的输出流
    ZipOutputStream zipOutputStream = ZipUtil.getZipOutputStream(outputStream, CharsetUtil.defaultCharset());
    ZipWriter zipWriter = new ZipWriter(zipOutputStream);
    zipWriter.close();
}
