通过Fegin远程调用 ，返回JPA Page 对象报错

大概意思是：不能构造实例org.springframework.data.domain.Page ：抽象类型要么需要映射到具体类型，要么有自定义反序列化器，要么用额外的类型信息进行实例化 。

换成PageImpl接受报如下错误：

Caused by: com.fasterxml.jackson.databind.JsonMappingException: Can not construct instance of org.springframework.data.domain.PageImpl: no suitable constructor found, can not deserialize from Object value (missing default constructor or creator, or perhaps need to add/enable type information?)
