좋은 강의 감사드립니다.덕분에 많은 걸 배워서 마음이 든든해 집니다.그런데, 하나 궁금한 점이 있어서 여쭤보고 싶습니다.우리 개발자들은 사실 귀찮은 걸 싫어하기 때문에 기술이 나날이 발전해 가는 것이라 생각이 되는데요, 강사님이 설명주신 부분처럼 Schema나 Payload를 계속해서 수동으로 만드는 것은 개발자 입장에서는 매우 비효율적일거라 생각이 됩니다.따라서, 이미 저 부분을 해결하기 위한 많은 부분들이 고려되었을 것으로 예상이 되는데요, 혹시 저 부분을 편하게 등록할 수 있는 다른 방법이 있을까요? 키워드라도 주시면 찾아서 공부해 나가는데 큰 도움이 될 것 같습니다. 감사합니다.

지금 제가 도커를 먼저 알고 싶어서 카프카까지 다 들은후 도커부터 듣는 중인데요. 근데 카프카할때부터인가 test를 다 안하고 넘기는 설정을 하시는거 같은데 왜 이렇게 하시나요?? 이게 실제 운영환경이라면 이렇게 못하잖아요?(테스트 코드가 있을 수도 있으니까요) 어떤걸 참고하면서 하면 이 상황을 타개해 나갈수 있을까요?

랜덤 포트를 지정하는게 좋다고 설명해주셨는데요Kakao login OAuth2 를 사용해서 로그인하는 경우 Redirect URI를 지정해야합니다. Gateway 주소(http://localhsot:8080/user-service/api/...)를 등록해도 결국 localhost:54241 이렇게 넘어 가기 때문에 에러가 발생하는데 이 경우에도 랜덤 포트 사용하는게 맞나요?

windows 10, eclipse에서 수업을 따라하고 있습니다.서버 동작도 안 되었는데.m2파일 중 configu와 관련된 내용 지우고 이클립스 다시 시작하니 config서버가 동작은 합니다.그런데git 레파지토리에 있는 ecommerce.yml파일을 읽지 못 하는지, 아니면 자신이 일반 서버로 착각하는지 404 에러가 납니다.이미지를 첨부했습니다.어떻게 해야 이 고통에서 벗어날 수 있을까요?동영상 강의 보면, 쉽게 배울 수 있을 거라 생각했는데동영상 강의 촬영일과 2년 정도 차이가 나니 이런 저런 걸로 계속 에러가 나네요.

안녕하세요. 강의에서 config-service의 yml 파일 내 uri와 jks 파일의 위치를 바꿔서 docker에서 실행해도 강의에서 나왔던 오류가 발생합니다. bootstrap.ymlencrypt: # key: abcdefghijkimnopqrstuvwxz0123456789 key-store: location: file:/apiEncryptionKey.jks password: test1234 alias: apiEncryptionKeyjks 파일의 위치를 Dockerfile과 동일한 경로에 복사했습니다. application.ymlserver: port: 8888 spring: application: name: config-server rabbitmq: host: 127.0.0.1 port: 5672 username: guest password: guest cloud: config: server: native: search-locations: file://C:\work\springcloud\git-local-repo git: uri: https://github.com/mjjunng/spring-cloud-config management: endpoints: web: exposure: include: health, busrefresh docker 실행 로그해당 에러를 확인해보면, 강의에서 파일의 위치를 변경하지 않았던 에러와 동일한 것으로 생각됩니다. 강의와 마찬가지로 파일 경로를 바꿔도 해당 에러가 발생하는데, 제가 놓친 부분이 있을까요?

강사님이 제공하기 파일로 진행하고 있었습니다..\bin\windows\connect-distributed.bat . \etc\kafka\connect-distributed.properties위의 명령어로 kafka connect을 실행하려하는데 아래와 같은 에러가 발생합니다.log4j:ERROR Could not read configuration file from URL [file:C:/Work/confluent-7.3.1/config/connect-log4j.properties].java.io.FileNotFoundException: C:\Work\confluent-7.3.1\config\connect-log4j.properties (지정된 경로를 찾을 수 없습니다)at java.base/java.io.FileInputStream.open0(Native Method)at java.base/java.io.FileInputStream.open(FileInputStream.java:219)at java.base/java.io.FileInputStream.<init>(FileInputStream.java:157)at java.base/java.io.FileInputStream.<init>(FileInputStream.java:112)at java.base/sun.net.www.protocol.file.FileURLConnection.connect(FileURLConnection.java:86)at java.base/sun.net.www.protocol.file.FileURLConnection.getInputStream(FileURLConnection.java:184)at org.apache.log4j.PropertyConfigurator.doConfigure(PropertyConfigurator.java:557)at org.apache.log4j.helpers.OptionConverter.selectAndConfigure(OptionConverter.java:504)at org.apache.log4j.LogManager.<clinit>(LogManager.java:119)at org.slf4j.impl.Reload4jLoggerFactory.<init>(Reload4jLoggerFactory.java:67)at org.slf4j.impl.StaticLoggerBinder.<init>(StaticLoggerBinder.java:72)at org.slf4j.impl.StaticLoggerBinder.<clinit>(StaticLoggerBinder.java:45)at org.slf4j.LoggerFactory.bind(LoggerFactory.java:150)at org.slf4j.LoggerFactory.performInitialization(LoggerFactory.java:124)at org.slf4j.LoggerFactory.getILoggerFactory(LoggerFactory.java:417)at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:362)at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:388)at org.apache.kafka.connect.cli.ConnectDistributed.<clinit>(ConnectDistributed.java:59)log4j:ERROR Ignoring configuration file [file:C:/Work/confluent-7.3.1/config/connect-log4j.properties].log4j:WARN No appenders could be found for logger (org.apache.kafka.connect.runtime.WorkerInfo).log4j:WARN Please initialize the log4j system properly.log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.log4j 가 없다는거 같은데 어떻게 해결할지 알려주시면 감사하겠습니다..

안녕하세요, 제 질문은 아래와 같습니다. '강의를 시작하며' 수업에서 본 강의는 'Spring Boot를 이용한 RESTful Web Services 개발' 강의의 후속 강의라고 말씀해주셨습니다. 기존에 Rest API를 알고 있음에도, 'Spring Boot를 이용한 RESTful Web Services 개발' 강의를 먼저 들어야만 할까요? 감사합니다.

DB 패스워드를 암호화하기 위해 key-store를 생성하게 되는데여기에서도 key-store의 패스워드가 yml 설정파일에 존재하게 되는 것으로 이해했습니다.key-store의 패스워드는 암호화 하지 않아도 되는건지 헷갈려서 질문드립니다.만약 암호화가 필요하다면 DB 패스워드를 암호화 하기 위한 key-store의 패스워드를 암호화 하기위한 key-store..... 이런식으로 무한루프가 돌 것 같은데 실무 환경에서는 어떻게 사용하고 있는지 궁금합니다.

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??

Users Microservice - JPA 수강중입니다.실습 따라서 작성하고 있는데 오류가 나는데 잘 모르겠습니다.UserServiceImpl 에서ModelMapper mapper = new ModelMapper();mapper.getConfiguration().setMatchingStrategy(MatchingStrategies.STRICT);UserEntity userEntity = mapper.map(userDto, UserEntity.class);userEntity.setEncryptedPwd("encrypted_password");여기까지 값이 잘 찍히다가 userRepository.save(userEntity); <-- 여기서 오류가 납니다. 2023-04-24T21:55:59.923+09:00 ERROR 3608 --- [o-auto-1-exec-6]

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'

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
