spring boot 啓動錯誤 Caused by: org.springframework.beans.factory.BeanCreationException

spring boot啓動報以下錯誤，

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.xx.feign.xxFeign': FactoryBean threw exception on object creation; nested exception is java.lang.IllegalStateException: No fallback instance of type class com.xx.feign.xxHystrix found for feign client xx-services

截圖以下

 

緣由是由於Hystrix 沒有加註解@Component

加完註解就啓動起來了
