内部平台的一个小功能点的实现过程，分享给大家：

递归解析Json，可以实现生成可视化Tree+快速获取JsonPath。

步骤：

1.利用JsonPath读取根，获取JsonObject

2.递归层次遍历JsonObjec，保存结点信息

3.利用zTree展示结点为可视化树，点击对应树的结点即可获取对应结点的JsonPath

1.利用JsonPath读取根，获取JsonObject

示例Json：

{"errorMessage": null,"errorCode": null,"dates": {"tradeAmt": null,"riskLevel": "LEVEL30","optSelected": {"77": [{"optionContent": "20-50万元","productCode": null,"created": null,"optionOrder": null,"modified": null,"id": 361,"optionScore": 8,"isInvalid": 1}],"78": [{"optionContent": "资产50-500万元，无债务或债务较轻","productCode": null,"created": null,"optionOrder": null,"modified": null,"id": 365,"optionScore": 6,"isInvalid": 1}]},"riskInfoResult": {"optLetter": "A","mqOrder": "1","residenceCountryCode": null,"taxReason": null,"residenceCountryName": null,"residenceCountryNameEn": null,"countryNameEn": null,"taxInfoCode": null,"taxInfoIsCompleted": true,"taxInfoIsRight": true,"countryCode": null,"taxId": null,"countryName": null,"taxReasonInt": null},"created": 1565654328000,"questions": [{"questionContent": "您的职业？","productCode": null,"created": 1498630051000,"options": null,"questionSource": "BUSINESS","modified": 1498630051000,"id": 75,"isInvalid": 1,"questionType": 1,"order": 1},{"questionContent": "您的主要收入来源是？","productCode": null,"created": 1498630051000,"options": null,"questionSource": "BUSINESS","modified": 1498630051000,"id": 76,"isInvalid": 1,"questionType": 1,"order": 2}],"serialCode": "123","isInvalid": 1,"expireTime": 1628783999000,"productCode": null,"modified": 1565654328000,"examScore": 56,"id": 4564568,"results": {"77": "361","78": "365"},"account": "test"},"status": "SUCCESS"
}

Java代码：

String jsonStr = "";
Object rootJson = JsonPath.read(jsonStr, "$");

2.递归层次遍历JsonObjec，保存结点信息

Java代码

ZTreeNode zTreeNode = new ZTreeNode();
zTreeNode.setId("$");
zTreeNode.setpId("root");
zTreeNode.setName("root");
zTreeNode.setDepth(0);
zTreeNode.setPath("$");
traverseTree(rootJson, zTreeNode, zTreeNodes);

    public static void traverseTree(Object rootJson, ZTreeNode zTreeNode, List<ZTreeNode> zTreeNodes) {if (rootJson instanceof Map) {for (Map.Entry<String, Object> stringObjectEntry : ((Map<String, Object>) rootJson).entrySet()) {ZTreeNode zTreeNodeTemp = new ZTreeNode();zTreeNodeTemp.setDepth(zTreeNode.getDepth() + 1);zTreeNodeTemp.setPath(zTreeNode.getPath() + "." + stringObjectEntry.getKey());zTreeNodeTemp.setId(zTreeNodeTemp.getPath());zTreeNodeTemp.setName(stringObjectEntry.getKey());zTreeNodeTemp.setpId(zTreeNode.getPath());zTreeNodes.add(zTreeNodeTemp);traverseTree(stringObjectEntry.getValue(), zTreeNodeTemp, zTreeNodes);}} else if (rootJson instanceof List) {List json = (List) rootJson;for (int i = 0; i < json.size(); i++) {Object obj = json.get(i);ZTreeNode zTreeNodeTemp = new ZTreeNode();zTreeNodeTemp.setDepth(zTreeNode.getDepth() + 1);zTreeNodeTemp.setPath(zTreeNode.getPath() + "[" + i + "]");zTreeNodeTemp.setId(zTreeNodeTemp.getPath());zTreeNodeTemp.setName(zTreeNode.getName() + "[" + i + "]");zTreeNodeTemp.setpId(zTreeNode.getPath());zTreeNodes.add(zTreeNodeTemp);traverseTree(obj, zTreeNodeTemp, zTreeNodes);}} else {// do nothing}}

3.利用zTree展示结点为可视化树，点击对应树的结点即可获取对应结点的JsonPath

前端代码：

let zTreeObj;
// zTree 的参数配置
let setting = {data: {simpleData: {enable: true}},callback: {onClick: zTreeOnClick}
};
zTreeObj = $.fn.zTree.init($("#using_json"), setting, zNodes);
zTreeObj.expandAll(true);

4.扩展：将结点信息反向解析

递归解析zNodes+利用nestable插件可视化展示，效果如下：

前端代码：

        let detailResult = JSON.parse(zNodes);let nestableContent = $('<ol class="dd-list"></ol>');let dataId = 0;// 遍历解析Jsonfunction parseJson(jsonObj, nestableContent, dataId) {for (let key in jsonObj) {let element = jsonObj[key];if (element === null) {element = "null";}if (element.length > 0 && typeof (element) == "object" || typeof (element) == "object") {var li = $('<li class="dd-item" data-id="' + dataId + '"></li>');$(li).append('                   <div class="dd-handle">' +'                       <span class="bg-muted p-xs b-r-sm">' + key + '</span>' +'                   </div>').append('<ol class="dd-list"></ol>').appendTo(nestableContent);parseJson(element, $(li).children().eq(1), dataId);} else {dataId++;$('<li class="dd-item" data-id="' + dataId + '"></li>').append('                   <div class="dd-handle">' +'                       <span class="bg-muted p-xs b-r-sm">' + key + '</span>' + element +'                   </div>').appendTo(nestableContent);}}}
