在对peopleJson反序列化时候报错：

Exception in thread "main" java.lang.ClassCastException: com.alibaba.fastjson.JSONObject cannot be cast to com.exa.demo2.PO.PeopleInfoPO

问题是因为：在使用String peopleJson = JSON.toJSONString(peopleInfoPO)没有加入类型信息SerializerFeature.WriteClassName

如果

把String peopleJson = JSON.toJSONString(peopleInfoPO)

改为

String peopleJson =JSON.toJSONString(peopleInfoPO，SerializerFeature.WriteClassName)

问题就解决了！
