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

토비의 스프링 부트 - 이해와 원리
강사님께서 application.properties는 스프링 프레임워크의 기본 동작 방식이 아니다 스프링 부트 초기화 과정에서 추가 해주는 거라고 말씀해주셨는습니다. @ContextConfiguration는 통합 테스트를 위해서 ApplicationContext를 로드하고, 구성요소 클래스를 넘겨주면 빈을 등록해주는거 같더라구요 SpringApplication.run을 할경우에는 Environment 구현체는 ApplicationServletEnvironment가 빈으로 등록이 되고, @ContextConfiguration로 테스트를 할경우에는 Environment 구현체는 StandardEnvironment 구현체가 빈으로 등록되는걸 확인했습니다. 그래서 Enviroment 구현체가 등록이 되면 application.properties를 가져올수있지 않나? 라는 생각에 해당 구현체를 찾아보니 StandardEnvironment 는 propertySource를 받지 않는걸 확인했습니다. 제가 궁금한건 1.같은 구성 정보 클래스를 넘겨주고 빈으로 등록을 했는데 구현체가 달라지는지 궁금합니다. 2.스프링부트에서 테스트를 하는데 @TestPropertySource를 따로 명시적으로 메타어노테이션으로 선언해서 사용하는 이유가 궁금합니다.

스프링 시큐리티 OAuth2
안녕하세요? 먼저 좋은 강의 감사드립니다. 실무에 많은 도움을 받고 있습니다. OAuth2.0 Roles(Resource Owner, Resource Server, Authorization Server, Client)의 개념에 대해 궁금한 점이 생겨서 아래 예시와 함께 질문드립니다. 카카오톡과 연동한 게임을 보면 게임내 순위 화면에 카카오톡의 프로필 사진이 사용되는 것을 알 수 있는데요. 이 경우 카카오톡의 OAuth2.0 인가 서버가 사용자 인증의 역할과 함께 리소스 서버(프로필 사진 제공)의 역할도 함께 수행하는 것으로 보이는데요 이게 맞을까요? 감사합니다.

스프링 배치
안녕하세요 JdbcCursorItemReader 와 JdbcBatchItemWriter를 이용해 기존 데이터를 변환해서 다른 테이블로 이관하는 테스트를 진행하고 있습니다. 근데 JdbcCursorItemReader 에서 select는 잘되는데 JdbcBatchItemWriter에서 insert쿼리를 날릴때 무한대기 현상이 발생하는거 같습니다. @Bean public Job transferDBJob(JobRepository jobRepository, Step transferBookStep){ return new JobBuilder("transferDBJob",jobRepository) .start(transferBookStep) .build(); } @Bean public Step transferBookStep(JobRepository jobRepository, PlatformTransactionManager tm, JdbcPagingItemReader<TransSpecies> pagingSpeciesReader, ItemProcessor<TransSpecies, Species> transItemProcessor, JdbcBatchItemWriter<Species> transItemWriter) { return new StepBuilder("transferBookStep",jobRepository) .<TransSpecies,Species>chunk(10,tm) .reader(pagingSpeciesReader) .processor(transItemProcessor) .writer(transItemWriter) .build(); } @Bean public JdbcPagingItemReader<TransSpecies> pagingSpeciesReader(DataSource dataSource,PagingQueryProvider createQueryProvider) { return new JdbcPagingItemReaderBuilder<TransSpecies>() .name("transSpeciesReader") .pageSize(10) .fetchSize(10) .dataSource(dataSource) .rowMapper(new BeanPropertyRowMapper<>(TransSpecies.class)) .queryProvider(createQueryProvider) .build(); } @Bean public PagingQueryProvider createQueryProvider(DataSource dataSource) throws Exception { SqlPagingQueryProviderFactoryBean queryProvider = new SqlPagingQueryProviderFactoryBean(); queryProvider.setDataSource(dataSource); queryProvider.setSelectClause("SPECIESKEY,AUTHOR,TITLE"); queryProvider.setFromClause("FROM TRANSSPECIES"); Map<String, Order> sortKeys = new HashMap<>(1); sortKeys.put("SPECIESKEY", Order.ASCENDING); queryProvider.setSortKeys(sortKeys); return queryProvider.getObject(); } @Bean public ItemProcessor<TransSpecies,Species> transItemProcessor(){ return transSpecies ->{ Species species = new Species(); species.setRecKey(transSpecies.getSpeciesKey()); species.setTitle(transSpecies.getTitle()); species.setAuthor(transSpecies.getAuthor()); return species; }; } @Bean public JdbcBatchItemWriter<Species> transItemWriter(DataSource dataSource){ return new JdbcBatchItemWriterBuilder<Species>() .sql("INSERT INTO SPECIES VALUES (:recKey, :author, :title)") .beanMapped() .dataSource(dataSource) .build(); } 현재 작성한 간단하 코드이며 로그에는 현재 이렇게 무한대기 상태에 놓이게 됩니다. 확인 부탁드립니다 ㅠㅠ

Spring Cloud로 개발하는 마이크로서비스 애플리케이션(MSA)
안녕하세요! 제가 강의를 다 듣고 난 뒤 추가로 공부를 해볼 생각으로 catalog-service 에서 example-catalog-topic 를 받은 뒤 상품의 개수를 파악 후 재고 유무의 따라 order-service 에 주문 상태를 전달 해주는 example-order-topic 를 만들어 구독 중인 order-service 에서 example-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??

public Long save(Member member) { em.persist(member); return member.getId(); } 리포지토리에 이 코드가 Member를 반환하지 않는 이유를 설명하면서 커멘드 메서드와 쿼리의 분리를 언급하셨습니다. 그래서 코드가 아무 값도 반환을 하지 않는 코드를 작성하실 줄 알았는데, 또 다음 설명에서 Id를 가져와 반환한 이유를 설명해주셨습니다. 그럼 Member 반환하는 코드는 CQS에 위배되지만, Id를 가져와 반환하는 것 까지는 CQS에 부합하는 코드라는 설명으로 이해해야하는 것인지 혼동됩니다. 제가 이해하기론 설명하고 반대되는 코드라고 생각되어 질문을 남깁니다. CQS에 대한 설명은 하셨지만, Id 정도는 의도가 있으니 Query해도 된다. 정도로 이해하면되는걸까요? 제가 이해못한 부분이 있다면 설명 부탁드리겠습니다. 감사합니다.

강사님께서 JdbcTemplate 과 JdbcTransactionManager는 따로 클래스를 만들고 적용하는 순서를 지정해야하는게 스프링 부트에는 있다고 하셨고 정석은 각각 다른 클래스로 만들고 적용하는 순서를 지정하는게 필요하다 이렇게 말씀해주셨는데 1.정석 방법을 찾아보고싶은데 어떻게 검색을 해야할까요? 그리고 편의 상 하나의 구성 정보에 넣으셨는데 2.하나의 구성정보하는게 더 간편한데 스프링은 정석인 방법 클래스를 나누어서 순서를 정해놓은 이유가 궁금합니다.

new UsernamePasswordAuthenticationToken(accountContext.getAccount(), null, accountContext.getAuthorities()); 아래처럼 토큰을 생성하신 이유가 궁금합니다. UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(accountContext.getAccount(),null, accountContext.getAuthorities()); 강사님께서 다른 질문에 답변해주신걸 보면 1. pricipal 객체는 UserDetails 타입의 Wrapper 객체가 아닌 실제 객체(?)를 참조하는게 더 낫다. 2. credentials는 이미 우리가 만든 CustomAuthenticationProvider에서 비밀번호를 검증했으므로 null로 세팅했다. 라고 이해햇습니다. 그렇다면 역으로 1. 다음 필터에서 principal 객체는 유저의 이름만 필요하다고하면 유저이름만 세팅해도 무방한가요? 즉, 어플리케이션에서 필요로하는 principal 객체가 무엇이냐에 따라 다르게 세팅하면 되는게 맞나요? 2. 다음 필터에서 credentials 항목을 필요로 한다면, 해당 항목도 null이아닌 account객체에 있는 패스워드로 채우는게 맞나요?

[질문 템플릿] 1. 강의 내용과 관련된 질문인가요? 예 2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? 예 3. 질문 잘하기 메뉴얼을 읽어보셨나요? 예 [질문 내용] 강의 후반부에 최악이 아닌 경우(한 명의 회원이 2개의 Order를 가질때) 영속성 컨텍스트에 멤버가 있기 때문에 멤버조회 쿼리가 1번 덜 나간다고 설명해주셨는데요. 같은 트랜잭션이어야 동일한 영속성 컨텍스트를 바라보기 때문에 강의에서 설명한 내용이 들어맞을 거라 생각하는데요. 강의에서는 트랜잭션을 설정해주는 부분이 안보여서요. 혹시 트랜잭션을 따로 설정하지 않으면 같은 리퀘스트 스코프 내에서는 동일 트랜잭션을 보장하는 기본설정??같은게 있는건가요? 아니면 혹시 제가 놓친 부분이 있을까요?
