多层嵌套集合的json，如何获取多层集合中所需要的value

就很简单的一个问题折磨了整整一天，压抑的心情终于释放了，终于闲下来觉得是不是应该记录一下。

首先这个json串是从外网接口返回的数据，想要了解的朋友们可以复制到json解析器中看一下格式：https://www.json.cn/#

期间用了alibab的fastjson包想要一层一层剥开这个json，结果浪费了许多时间还是没有效果，估计是方法使用错了，这里就直接贴上成功的方法。

首先还是先建了实体类，这里比较简单，就是按照json的格式一层一层往下写，就直接贴代码了。

才想起来要不要折叠一下，这会不会太长了，但是我实在太懒了，对不起我就不去重新操作了。

实体类建完以后我就尝试了一下，也不再使用alibab的fastjson，使用如下这个包：

import net.sf.json.JSONObject;

maven依赖如下：

<dependency>
            <groupId>net.sf.json-lib</groupId>
            <artifactId>json-lib</artifactId>
            <version>2.4</version>
            <classifier>jdk15</classifier>
</dependency>

最终代码如下：

 1 public static void main(String[]args){
 2
 3         String json =
