主要用到的依賴：（劃重點：這個依賴需要加jdk版本號，不加的話用不了，且目前最高是jdk15）

（ps: 用於json與其他型別格式轉換，JSONObject, JSONArray等來自這個包）

import java.util.ArrayList;

        if (json instanceof JSONArray) {

            jsonArray.forEach(j -> analysisRequestJson(j));
        }

            Iterator iterator = jsonObject.keys();
            while (iterator.hasNext()) {
                String key = iterator.next().toString();
                Object o = ((JSONObject) json).get(key);
                if (o instanceof JSONArray) {
                    JSONArray jsonArray = (JSONArray) o;
                    analysisRequestJson(jsonArray);
                } else if (o instanceof JSONObject) {
                    List<BaseNode> list = analysisRequestJson((JSONObject) o);
                    nodeContainer = new NodeContainer(key, null, list);
                } else {
                    baseNodeList.add(new NodeLeafConstant(key, o.toString(), o.getClass().getTypeName().replace("java.lang.", "")));
                }
            }
            if (CollectionUtils.isNotEmpty(nodeContainer.nodeList)) {
                baseNodeList.add(nodeContainer);
            }
        }
