json类型数据取出想要的部分

因为才疏学浅，只能用很笨的方法。

以下是我拿到的数据的json型数据。

{"result":{"ingredient":{"result":[{"score":0.9999989,"name":"香蕉"},{"score":7.754284E-7,"name":"小米蕉"},{"score":1.252173E-7,"name":"芭蕉"},{"score":5.0951E-8,"name":"蒲瓜"},{"score":2.0919343E-8,"name":"茄子"}],"log_id":1585606298733704458,"result_num":5},"red_wine":{"result":{"wineNameCn":"","hasdetail":0},"log_id":1585606299218276580},"plant":{"result":[{"score":0.8585518,"name":"香蕉"},{"score":0.013570859,"name":"芭蕉"},{"score":0.0024424153,"name":"大蕉"}],"log_id":1585606300248077894},"animal":{"result":[{"score":"0.999349","name":"非动物"}],"log_id":1585606298772283861},"currency":{"result":{"currencyName":"","hasdetail":0},"log_id":1585606300350185185},"dishs":{"result":[{"probability":"0.992685","has_calorie":false,"name":"非菜"}],"log_id":1585606299300899292,"result_num":1},"landmark":{"result":{"landmark":""},"log_id":1585606300247546709}},"log_id":16668729751268258}

我想拿到第一位的香蕉。

点击查看代码

JSONObject object= JSONObject.parseObject(result);//转化成JSONObject型，取出plant字段。

            JSONObject a =object.getJSONObject("result").getJSONObject("plant");

            System.out.println(a);//看看取出来的是不是想要的。

            JSONObject b=a.getJSONArray("result").getJSONObject(0);//因为它里面是一个数组，所以想要单独拿出来就得做一个array类型转换，并且取到第一个值。

            System.out.println(b.getString("name"));//查看你想要的字段。

注释即是思路！
