안녕하세요!먼저 강의 너무너무 잘 보고 있습니다!공부를 하다가 갑자기 궁금한게 생겼는데,여러 개발자와 협업해야하는 환경이 될 때같은 서비스를 개발 할 시 개발 환경이 어찌 되는지 알고 싶습니다.Q1. 같은 서비스 개발 할 때에 디스커버리 서버와 APIGateway를 각자 개발자가 켜놓고 연관 된 서비스들도 다 실행 한 뒤에 개발을 하는지..Q2. 아니라면 APIGateway를 공용으로 사용시 따로 환경세팅이 있을까요?APIGateway를 공유하고 같은 서비스를 켜놓고 개발을 진행시 프론트에서 서비스 API등 호출 할 때에 제가 아닌 다른분의 서비스에 들어가면 어쩌지? 하는의문에서 시작되었습니다.너무너무 궁금합니다..강의는 너무 잘 보고 있고 다음강의도 기대하겠습니다!감사합니다.

- 학습 관련 질문을 남겨주세요. 상세히 작성하면 더 좋아요! - 먼저 유사한 질문이 있었는지 검색해보세요. - 서로 예의를 지키며 존중하는 문화를 만들어가요. - 잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요.

강의에서 안내하는 bootstrap.yml을 똑같이 만들어주고 application.yml에서 아래 코드를 추가하면 됩니다. 아래서 경로 자체를 연결하는 방법도 댓글로 알려주셨는데 저는 저게 잘 안 되서 이렇게 해결했습니다. spring: config: import: - classpath:/bootstrap.yml

안녕하세요. 강의 수강중 intellij 버전이 달라서인지, jdk 버전이 달라서인지 몰라도 아래 run/debug config 화면에서 Enviroment 옵션이 보이지 않습니다. 유레카 실습 중이고 한개의 프로젝트에서 여러 서비스를 실행시킬 때 VM option을 사용해서 포트를 변경 하려 하는데 해당 옵션이 보이지 않아 문의 드립니다. Intellij 버전은IntelliJ IDEA 2022.2 (Ultimate Edition) /  Build #IU-222.3345.118, built on July 26, 2022 입니다. 구글링을 해도 못찾겠어서 질문 드려요~!   이것 저것 누르다 보니 찾았습니다. Modify options 에서 VM options 라는 항목이 따로 있네요...   혹시 run/debug configuration 창의 형태(?)를 강의 하시는 화면과 동일하게 변경하는 옵션이 따로 있을까요..?

modelmapper의 경우 자주 사용될 것 같은데bean으로 등록 해두고 사용하는게 좀 더 유리할까요?? userEntity -> userDto로 변환하여 리턴할때 기존에 파라미터로 받았던 dto값을 그대로 넘겨줘도 될 것 같은데요! 굳이 변환해서 넘겨주는 의도가 어떤것인지 궁금합니다!

안녕하세요. 윈도우 환경에서 강의를 듣던 중에 막히는 부분이 있어서요.  PS C:\Users\hoirias\confluent-6.1.0> .\bin\windows\connect-distributed.bat .\etc\kafka\connect-distributed.properties Error: Could not find or load main class org.apache.kafka.connect.cli.ConnectDistributedCaused by: java.lang.ClassNotFoundException: org.apache.kafka.connect.cli.ConnectDistributed   아직 properties 파일 등을 수정하진 않은 상태인데요, 강의를 보면 수정 전에도 돌아는 가야 하는걸로 보여서요. 자바 버전은 현재 18.0.1.1을 사용하고 있으며, 컨플루언트 doc 참조하여 11.0.4까지 낮췄는데도 동일한 현상 입니다.   

api gate way 서버에서 refresh를 해도 모든 서버에 다 적용이 되는건가요 ? 가령 ecommerce.yml파일에서 토큰 정보를 바꿨는데 api gate way 서버 api로 refresh를 해도 유저 서비스에 token도 바뀌는 건가요? 강의에서는 그렇게 나오긴했는데 맞는지 확시히 잘 몰라서 질문드립니다

  안녕햐세요. 윈도우에서 강의 실습을 하고 있습니다. sh 실행이 안되어 관련 내용을 찾다보니 윈도우는 개발환경을 설정해야 하는데 관련 설정방법을 알수가 없어서요.    WSL 개발 환경 설정(링크) 라고 되어 있는데, 어디서 확인이 가능할까요?

안녕하세요. 강의를 통해서 Kafka에 대한 개념을 다 잡을 수 있었습니다.Flink와 Kafka Streams 비교를 위하여 질문 드리고자 해요.현재 업무 중 CDC를 이용하여 받아온 데이터를 Kafka에 인입하고 있고, 해당 데이터를 Flink로 가공하여 다시 Kafka Topic에 넣고 있어요.여기서 든 생각이 이럴거면 Kafka Streams를 쓰는 것이 어떨까라는 생각이 들더라구요.Kafka Streams를 Flink 대신 사용하여 얻을 수 있는 이점에 대해서 궁금합니다.   감사합니다.

min.insync.replicas=2의 경우 복제가 완료된 개수를 말하는 것이라고 이해했습니다. 다만 강의의 그림에서 브로커#0(리더 파티션) 1개와 브로커#1(팔로워 파티션) 1개를 합쳐 2개가 됐다는 것으로 이해하면 될까요? 브로커#0(리더 파티션) + 브로커#1(팔로워 파티션) = 2 replicas 이 경우 1개가 복제 완료되었다고 말할 수 도 있을 것 같아서 헷갈리네요. 복사본의 갯수로 이해하는 것보단 실제 데이터 세트의 개수로 이해하는 것이 더 맞을까요?  

트랜잭션 컨슈머를 만들고, 일반적인 트랜잭션을 사용하지 않는 프로듀서로 데이터를 생성하였을 때, 트랜잭션 컨슈머가 이를 읽는것을 확인하였습니다.   명시적으로 트랜잭션을 커밋하지 않는 프로듀서도 레코드를 커밋한다고 생각하면 되는걸까요?

        안녕하세요 강사님 강의 진짜 잘 듣고 있습니다! 설명 너무나 잘 해주시는데, 제가 이해 한걸 확인 좀 하고 싶어서 질문 합니다. spring MSA가 유레카서버(eureak server)에서 각 모듈(eureka client)들의 API 주소를 등록 하고, 클라이언트에서 gateway(eureka client)를 통해 들어오면 gateway에서 각 API를 호출 하는 형식인가요?

spring: application: name: user-service cloud: config: name: ecommerce config: import: optional:configserver:http://localhost:8888 application.yml   버전업이 되면서 boostrap.yml을 작성하는게 레거시가 되버렸네요... 그냥 application.yml에서 작업해도 될 것 같습니다

- 학습 관련 질문을 남겨주세요. 상세히 작성하면 더 좋아요! - 먼저 유사한 질문이 있었는지 검색해보세요. - 서로 예의를 지키며 존중하는 문화를 만들어가요. - 잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요.   안녕하세요. rabbitMQ 도커 기동 관련해서 질문드립니다.   도커로 rabbitMQ를 기동하면서 기존에 사용하던 포트번호를 그대로 사용하는거 같은데, 현재 로컬 PC에선 기존에 설치했던 rabbitMQ가 돌아가면서 해당 포트를 사용하고 있는거 같습니다. (컴퓨터 부팅 후 따로 설정하지 않아도 15672 포트로 웹 관리 콘솔에 접근이 되더라구요)   이러한 부분에 관해 설정을 따로 하거나 로컬의 rabbitMQ를 삭제하지 않아도 문제가 없을까요? (추가적으로 MQ를 설치하면서 함께 설치했던 erlang을 로컬에서 삭제해도 도커에선 문제없이 작동하는지도 궁금합니다)

안녕하세요. 강의 내용중에 Event Driven Architecture 파트 설명중에 Commit Trancation에서는 상태값을 두어 하나의 트랜잭션에 여러 Row가 기록되지 않는데, 다음에 설명하는 Event Sourcing 파트에서는 데이터의 마지막 상태만 저장하는 것이 아닌, 해당 데이터에 수행된 전체 이력을 기록한다고 설명하고 있습니다. 이 부분이 헷갈리는데, 데이터를 관리하는 방식이 서로 다른데 (그 외 Saga pattern 등) 상황에 맞게 쓰면 된다는것인가요?   Event Driven Architecture라는 큰 개념이 있고 그 하위?에는 Event Sourcing, Saga pattern 등 다양항 방법이 있다고 생각하고 있는데 잘못 이해한것일까요?   감사합니다.  

이렇게 설정 하였지만, UserController requestMapping부분에서 user-service 부분을 빼고 요청 보내면 자꾸 404 에러가 뜹니다.. 그래서 다시 userController requestMapping에 user-service를 추가하니깐 404 에러 없이 데이터를 가져 오더라구요.. 그래서 지금 login 부분을 계속 실패하고 있는데, 뭐가 잘못되었는지 알 수 있을까요??   아 참고로 - RewritePath=/user-service/(?<segment>.*),/$\{segment} 이 모양과 - RewritePath=/user-service/(?<segment>.*), /$\{segment} 이 모양 둘다 해봤지만 결과는 계속 404 에러를 리턴합니다..

실습 따라서 하다가 문득 궁금해서 질문남깁니다. 이전 강의에서 말씀하셨는지 찾기어려워서 ..   Cloud Gateway 애플리케이션을 Eureka Server에  등록하는 이유가 뭔가요? 인스턴스로 등록할 각 서비스들만  구독 시켜둬도 운영은 가능한게 아닌가요..? 직접 해보니fetch-registry, register-with-eureka 를 false 로 해도 되기는 하더라구요.   따로 적어둔거를 봤는데  fetch-registry, register-with-eureka 를 true로 하는 것이 유레카 서버로 부터 갱신된 인스턴스 정보들을 받기 위함이라고 적어두긴했는데 맞는건가요?

안녕하세요! 좋은 강의 잘 보고 있습니다~   제플린 파트에서 다음과 같은 오류를 만나게되었는데 혹시 제가 놓친 부분이 있을까요?? 오류 메세지만으로는 알기가 좀 어렵네요 ㅠ   작성 내용은 예제 소스에서 biz_date 부분만 바꾸었습니다.
