今天使用feign時 遇到一個問題  消費者啟動一直報bean找不到

網上找了一下，大部分都說啟動類@SpringBootApplication沒有掃描到接口類所在包，但是我按照上面說的依舊沒成功。

直到后來發現我的問題錯在哪里

錯誤展示：

接口：

回調：

錯誤原因：

fallback類型時 對應回調應該是實現BizOrderAccpetAPI接口 ，重寫方法

fallbackFactory類型時 對應回調應該是實現FallbackFactory<BizOrderAccpetAPI>接口,重寫方法

 

正確配置：

第一種方式：fallback

 接口：

回調：

 

第二種方式：fallbackFactory

接口：

回調：

 

特此記錄

feign重試設置1

 feign重試設置2
