Caused by: com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of `com.baomidou.mybatisplus.core.metadata.IPage` (no Creators, like default construct, exist): abstract types either need to be mapped to concrete types, have custom deserializer, or contain additional type information
at [Source: (PushbackInputStream); line: 1, column: 1]

Mybatis-plus的 IPage，沒有默認的構造器，通過feign調用時報錯

解決方法就是用另一個類包裝IPage對象，添加需要的IPage里的數據就行
