eureka.clinet.fetch-registry : true 의미가 클라이언트가 유레카 서버를 통해 다른 서비스 정보를 얻기을 수 있다고 알고있습니다. 여기서 궁금한 점이 있는데인스턴스가 다른 인스턴스의 정보가 필요한 이유가 자신이 받은 요청이 다른 인스턴스의 서비스가 필요할 떄가 있어서 그런 건가요??

안녕하세요. 저같은사람이 없기를 바라며 오류 해결법을 올립니다...환경은 23년 기준 스프링부트. 스프링클라우드 모두 최신버전입니다. (대신 강의처럼 maven이 아닌 gradle입니다)23년 4월중순부터 강의를 잘 따라하다가 빌드후 실행하면 user-service에서 에러가 나는겁니다.openfeign 관련 에러였습니다.  org.springframework.beans.factory.BeanCreationNotAllowedException: Error creating bean with

"코루틴이 JVM의 힙 ㅁ메로리를 공유해서 사용한다. 따라서 스레드의 경우 한 스레드에서 다른 스레드로 넘어갈 때 컨텍스트 스위칭이 일어나지만 코루틴은 일어나지 않아 오버헤드가 적다" -> 이 전제에서 틀린 것이 있을까요?

터미널에서 9003 포트 실행할 때, 9001 포트가 중복된다고 발생하는 경우는 명령어가 잘못되서 그렇습니다. 강의랑 조금 다르네요 ' ' 해당 부분을 확인해주세요. mvn spring-boot:run '-Dspring-boot.run.jvmArguments=-Dserver.port=9003'

안녕하세요 수강 생 입니다다름이 아니라 part 10을 수강하고 있는 단계에서앱 빌드가 안되어 구글을 검색 해봤으나 실용적인 답변을 얻지 못해 문의 드립니다오류 코드 맥락은 대략 이해가 되나 코드가 잘 못 쳐진 부분이 없어 어떻게 해결 점을 찾아야 하는지 여쭤 보고 싶습니다

K8S나 Docker Swarm 없이 2대 이상의 Host PC에 Multi Cluster를 구성할 수 있을까요?혹시 2대의 PC에 각각 Docker를 설치하고, 여기에 분산되서 올라간 Container들을 하나의 Network으로 묶는것이 가능한가 해서요.방법이 있으면 알고 싶습니다

안녕하세요!제가 강의를 다 듣고 난 뒤 추가로 공부를 해볼 생각으로catalog-service 에서 example-catalog-topic 를 받은 뒤상품의 개수를 파악 후 재고 유무의 따라 order-service 에주문 상태를 전달 해주는 example-order-topic 를 만들어 구독 중인 order-service 에서example-order-topic 에서 전달 받은 주문 상태를 업데이트 하는 로직을 구현하려고 했습니다.로컬에서 order-service 와 catalog-service 의 consumer groupId 를 consumerGroupId 로 통일해서 사용 했을 때는 괜찮았으나, docker 에 올리니 example-order-topic 이 생성은 됐으나 구독 및 전달이 되지 않더라구요.... 혹시나 해서 order-service 의 consumer groupId 를 consumerGroupId2 로 변경하여 docker 에 올리니 정상 작동이 됩니다. 혹시 각각의 service 는 groupId 를 다르게 해주어야 할까요??

안녕하세요. 교육 내용이 도움이 많이 되어 완강 했습니다.죄송하지만, 혹시 교육에서 사용한 PPT 문서 보내 줄 수 있을까요?협업 할 때 참고하면 많은 도움이 될 것 같습니다.이메일 주소는 mytechnic@gmail.com 입니다.감사합니다.

spring config를 적용하면 설정 값들에 암호화를 수행하여 "{cipher}..." 구문으로 적용할 수 있는데, bootstrap.yml 파일의 "encrypt.key-store.password", "encrypt.key-store.secret" 항목의 값은 암호화를 어떻게 할 수 있는지 방법 부탁드립니다.

 솔직히,, MVC나 MVP나 MVVM이나 머가 그렇게 다른지 잘 이해가 안가긴합니다..모델과 뷰를 분리하고 이를 컨트롤하는 영역을 어떻게 처리하면 좋을까 하는데서 조금씩 차이가 있어서 구분하려는게 목적인 걸까요. 뷰모델이라 한다해도 처리해야할 복잡성이 올라가면 결국 복잡해지는 건 똑같아 보입니다.. 그럼에도 불구하고 UIKit을 사용할 때 NVVM을 쓸라고 하는건 테스트가 용이하다는 이유랑, 그냥 옵저버 패턴 쓰고 싶어서인 것 같습니다. Combine이 나온 것도 뭔가 너네가 옵저버 방식 좋아하는 것 같으니까 만들었어 같은 느낌인 것 같고,, SwiftUI를 공부하면서 보니까 자연스럽게 Combine 쓰게되고 쓰다보니 자연스레 아래처럼 구조가 분리되는 것 같은데 이게 NVVM이 맞는 걸까요?뷰(들어오는 데이터 대로 그려지는 뷰 구조체 모음)모델(타입 or 인터페이스 모음)로직(뷰의 로직 처리 함수모음)스토어(상태 데이터모음) 

 sink도 잘 등록되었고, orders topic에 json 값도 잘 전달되지만 전달된 값이 디비에는 반영되지 않아 데이터 삽입이 되지 않습니다. ㅠㅠ무엇이 문제일까요?

response.getBody() 뭐 이런식의 메서드가 없어서요...getHeader()는 있는데.... body의 특정 문자열을 바꿔서 리턴하고자 해서 문의 해봅니다.

안녕하세요. 강의 정말 잘 들었습니다. 많은 도움이 되고 있습니다. 다름이 아니고,각 도메인모델을 도출하고 난 후, 경우에 따라 여러 모델을 일관성 있게 업데이트해야하는 경우 유스케이스(서비스)를 이용하게 되는데요. 유스케이스의 디자인은 어느 시점에 어떻게 해야하는지 궁금합니다. 강의내용에서는 모델(entity)만을 도출하고 난 후, 패턴을 언급하며 마무리하고 있어서,실질적으로 구현을 위한 유스케이스 디자인 단계가 빠져 있는거 같아서요. 감사합니다! 

강사님! 직렬화 라이브러리를 Moshi, kotlin serialization 두개를 사용하시던데 이유가 있으신가요?찾아보니까 코틀린의 serialization 만 이용해도 되지 않을까해서요retrofit 에서도 제이크와튼이 만든 컨버터 라이브러리도 있더라구요?https://github.com/JakeWharton/retrofit2-kotlinx-serialization-converter#download그런데 0.8 버전이긴하네요;;;혹시 어떤 이유가 있으셔서 room 에는 serialization, retrofit 에는 moshi 를 사용하신걸까요?!그리고 매번 답변해주셔서 정말 감사합니다 (__)

안녕하세요! 좋은 강의 제공해주셔서 감사합니다. 다름이 아니라, 수업에서 JWT 토큰 유효성 로직을 api gateway service에 구현했는데, user-service가 아닌 gateway service에 구현한 이유가 있을까요? api gateway에 토큰 유효성 로직을 구현하게 되면, 만료된 토큰으로 api gateway를 거치지 않고 바로 user-service에 요청하는 경우, 토큰 유효성 검사를 하지 않아서 문제가 발생할 수 있지 않나요?

EditText 는 saveState 가 활성화되어있어서id 만 지정하면 시스템언어변경하거나해도 잘 불러오더라구요그래서 강사님처럼 kill 명어로도 강제 종료를 시켜봤는데그래도 잘 복원이 되더라구요강의에서 kill 로 종료하면 복구가 안되기 때문에 직접 뷰모델에 SaveStateHandle 을 이용하신다고 했는데그럼 실제 개발할때는 EditText 뷰인경우 SaveStateHandle 을 사용하지 않아도 될까요?
