以下只是草稿,较粗糙,详细的用法请参考:

一.result格式:

{

    "success":"true",

    "returnAddress":"123"

}

JSONObject jsonObject=JSON.parseObject(result);      //转换成object

   jsonObject.getString("returnAddress")    //获取object中returnAddress字段;

二.result格式:

{

    "success":"true",

    "data":{

        "shop_uid":"123"
    }

}

JSONObject shop_user =JSON.parseObject(result);

JSON.parseObject(shop_user.getString("data")).getString("shop_uid")

多级嵌套json取值(踩坑):

result格式:

{
	"success": "true",
	"data": {
		"shop_uid": "123",
		"dataChild": {
			"uidChild": "456"      //多层json嵌套
		}
	}
}

获取uidChild:

JSONObject shop_user =JSON.parseObject(result);

//注意:多层嵌套这里data不能先用getString("data"), 再parseObject来获取dataChild对象
JSONObject dataObject = shop_user.getJSONObject("data");

dataObject.getJSONObject("dataChild").getString("uidChild");

三.result格式:

{

    "success":"true",

    "data":[{

        "shop_uid":"123"

    },

    {

        "shop_name":"张三"

    }]
}

Map<String,String> ship = new HashMap<>();
JSONArray detail = JSON.parseArray(result);
for (int i=0; i<detail.size();i++){
    JSONArray detailChild =detail.getJSONArray(i);
    ship.put("shiptime",detailChild.getInteger(1));
    ship.put("desc",detailChild.getString(0));
}

JSON转javaBean

1.1 JSONobject=>javaBean

JSONObject contentChild = contentsArray.getJSONObject(i);
QCCustomerScore.CustomerCore customerCore = JSON
        .toJavaObject(contentChild, QCCustomerScore.CustomerCore.class);

1.2 String转javaBean
