合并两个嵌套的org.json.JSONObject [英] merge two nested org.json.JSONObject

问题描述

我有两个来自org.json的JSON对象:第一个是

I have two JSON object from org.json: the first one is

json1 = {a: {b : {c: val1} } }

第二个是

json2= {a {b: {c2: val2 } } }

是否可以将这两个对象合并为一个对象，如下所示:

is there any way to merge this two object to have one object like this:

result = {a: { b: {c: val1, c2: val2 } } }

我对两个对象的键一无所知，所以我需要动态地循环遍历这些对象并进行合并.有没有内置的方法可以做到这一点.谢谢.

I don't have any idea about the keys of the two objects, so i need to loop dynamically over these objects and do the merge. Is there any built in method to do this trick. Thanks.

推荐答案

static JSONObject merge(JSONObject obj1, JSONObject obj2) {
    obj2.forEach((k2, v2) -> obj1.merge(k2, v2, (v1, _v2) ->
            v1 instanceof JSONObject && _v2 instanceof JSONObject
                    ? merge((JSONObject)v1, (JSONObject)_v2) : "conflict!!"));
    return obj1;
}
