Cause Analysis

It may be caused by the SpringBoot version being too high and incompatible with the transitively dependent spring-cloud-starter-feign.

spring-cloud-starter-openfeign is an open source version based on spring-cloud-starter-feign. The implementation is basically the same. spring-cloud-starter-openfeign introduces some functions and features that spring-cloud-starter-feign does not have. It is spring - An extended and enhanced version of cloud-starter-feign.

spring-cloud-starter-feign only supports Spring boot 1.4.7 or lower SpringBoot version

solution

If the current project SpringBoot version is higher than 1.4.7, or directly or indirectly introduces spring-cloud-starter-openfeign, spring-cloud-starter-feign may need to be excluded, otherwise dependency conflicts will occur.
