解析json格式数据 获取自己需要的对象

获取指定对象的值

String result = "下面的json数据";
JSONObject jsonObject = JSONObject.fromObject(result);
        // 取指定对象 filters
        JSONArray filters = (JSONArray) jsonObject.get("filters");
        // 取对应filters对象中的值  key - value  通过key 获取对应的value值
        jsonObject1.get("key");
        // 获取filters数组中包含filter为 1,2 的对象
        String filterId = "1,2";
        String[] filterId = filterIds.split(",");
        JSONArray jsonArray = new JSONArray();
        filters.forEach(item -> {
            JSONObject jsonObject1 = JSONObject.fromObject(item);
            for (String s : filterId) {
                if (jsonObject1.get("filterId").toString().equals(s)) {
                    jsonArray.add(jsonObject1);
                }
            }
        });
        // 得到需要数据
        return jsonArray;
