当前使用版本(必须填写清楚，否则不予处理)
3.1.1
该问题是怎么引起的？(最新版上已修复的会直接close掉)
因为IPage是接口无法反序列化，改用Page，但是反序列化失败
重现步骤
通过Feign访问返回Page数据的接口
R

别人能用page直接接收,你用R再包了page,自己排查
Comment From: wxdfun
重写setPages 加上JsonIgnore
Comment From: johnxiaohe
不用R用page直接返回也报错 会提示说期望是个类返回的是个接口 为啥呀
Comment From: LiYeLin
解决了吗？怎么被关闭了 我也碰见了一样的问题
Comment From: LiYeLin
也是因为Ipage的问题换成了Page 然后就出现这个问题 最后只能使用List了

使用包装类，最后使用wraper转回来

我的意思你搞个转换类，自定义一个类存放这些分页和结果信息的类。用转换类转换一下传输回去。再转回到IPage

懂了，我现在用了Map来传递那些分页信息和结果信息，其实和你说的转换类一个道理，但我想了一下好像还是你说的新写个类比较方便以后维护。
