안녕하세요 user-service 실행 시 feign client 관련 에러가 나는 것 같아 질문 드립니다.
먼저 강의에서 나온 대로 디펜던시 추가 시
WARNING: An illegal reflective access operation has occurred

***************************
Description:
An attempt was made to call a method that does not exist. The attempt was made from the following location:
org.springframework.cloud.sleuth.instrument.web.client.feign.TraceRetryableFeignBlockingLoadBalancerClient.<init>(TraceRetryableFeignBlockingLoadBalancerClient.java:60)
The following method did not exist:
org.springframework.cloud.openfeign.loadbalancer.RetryableFeignBlockingLoadBalancerClient.<init>(Lfeign/Client;Lorg/springframework/cloud/loadbalancer/blocking/client/BlockingLoadBalancerClient;Lorg/springframework/cloud/client/loadbalancer/LoadBalancedRetryFactory;)V
The method's class, org.springframework.cloud.openfeign.loadbalancer.RetryableFeignBlockingLoadBalancerClient, is available from the following locations:
jar:file:/C:/Users/SAMSUNG/.m2/repository/org/springframework/cloud/spring-cloud-openfeign-core/3.0.2/spring-cloud-openfeign-core-3.0.2.jar!/org/springframework/cloud/openfeign/loadbalancer/RetryableFeignBlockingLoadBalancerClient.class
The class hierarchy was loaded from the following locations:
org.springframework.cloud.openfeign.loadbalancer.RetryableFeignBlockingLoadBalancerClient: file:/C:/Users/SAMSUNG/.m2/repository/org/springframework/cloud/spring-cloud-openfeign-core/3.0.2/spring-cloud-openfeign-core-3.0.2.jar
Action:
Correct the classpath of your application so that it contains a single, compatible version of org.springframework.cloud.openfeign.loadbalancer.RetryableFeignBlockingLoadBalancerClient
Process finished with exit code 0
위와 같은 오류가 호출 됩니다. 그 후 feign client의 버전을 3.0 이하로 내려서 실행하였더니 feign client 가 빈으로 생성시 오류가 생기 며
No Feign Client for loadBalancing defined. Did you forget to include spring-cloud-starter-netflix-ribbon or spring-cloud-starter-loadbalancer?
해당 오류가 호출 됩니다
답변 부탁드립니다.

질문 드린 오류 관련해서 검색하여 보니 sleuth 와 함께 사용하여 발생 하는 오류라는 글을 보고
sleuth 디펜던시를 막고 실행 하였더니 정상적으로 실행이 되었습니다. 자세한 내용은 안나와 있어서 모르겠내요 ... 아래는 pom.xml 입니다.

안녕하세요, 이도원입니다.
작업하신 Feign Client의 버전이 3.0.2 라고 하셨는데, 추가하신 pom.xml 파일을 공유해 주실 수 있을까요? 다른쪽 라이브러리와의 문제일 수 있을 것 같습니다. 제가 사용하는 Fieng Client의 Dependency 부분은 다음과 같습니다.
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-openfeign</artifactId>
</dependency>
참고로, 3.0 이하 버전을 사용할 시 발생하는 오류는 버전 다른 Netflix OSS 라이브러리들을 사용하고 있어서 추천드리지 않습니다.
감사합니다.
