针对urlencode和decode
URLDecoder.decode(url);
URLEncoder.encode(url);
浏览器urlencode后的解析
StringEscapeUtils.unescapeHtml(info)
类似array_column
JSONArray data = new JSONArray();
List<String> pkIndexList = data.stream().map(o -> JSON.parseObject(o.toString()).get("pkIndex").toString()).collect(Collectors.toList());
类似于crc32
CRC32 c = new CRC32();
c.update(this.getUUID(request, response).getBytes());
uid = c.getValue() % 1000000;
