select 쿼리없이 dto 만들지 않은 이유

미해결

실전! 스프링 부트와 JPA 활용2 - API 개발과 성능 최적화

강의에서는 아래와 같이 select 쿼리를 이용해 업데이트 된 회원을 조회후 response로 전달해 주었는데 @PutMapping("/api/v2/members/{id}") public UpdateMemberResponse updateMemberV2(@PathVariable("id") Long id, @RequestBody @Valid UpdateMemberRequest request) { memberService.update(id,request.getName()); Member findMember = memberService.findOne(id); return new UpdateMemberResponse(findMember.getId(), findMember.getName()); } 아래와 같이 하지 않은 이유가 있을까요?? @PutMapping("/api/v2/members/{id}") public UpdateMemberResponse updateMemberV2(@PathVariable("id") Long id, @RequestBody @Valid UpdateMemberRequest request) { memberService.update(id, request.getName()); return new UpdateMemberResponse(id, request.getName()); }

콘솔에서 컨슈머 생성

미해결

카프카 완벽 가이드 - 코어편

토픽을 구독하는 컨슈머를 콘솔에서 생성하면, 생성하는 컨슈머마다 항상 새로운 그룹이 만들어지게 되는거고 해당 토픽에 내부 파티션인 __consumer_offset가 생성된 컨슈머의 수만큼 만들어지는게 맞나요? 자바의 KafkaConsumer 를 사용할때 이미 존재하는 컨슈머 그룹에 참여한다면, 토픽에는 해당 컨슈머 그룹에 대한 정보인 __consumer_offset이 이미 존재하고 컨슈머에서 이 값을 읽어오니 earlist로 설정해도 0번 인덱스 레코드부터 읽는게 아닌 __consumer_offset에서 offset 값을 그대로 읽어와 사용하는게 맞나요?

2023.08.10 기준 Spring Boot 3버전 대 Security Config 설정 파일 공유합니다.

미해결

Spring Cloud로 개발하는 마이크로서비스 애플리케이션(MSA)

@Configuration @EnableWebSecurity @RequiredArgsConstructor public class WebSecurity { private final UserService userService; private final BCryptPasswordEncoder bCryptPasswordEncoder; private final Environment environment; @Bean public SecurityFilterChain filterChain(HttpSecurity http) throws Exception { http.csrf(AbstractHttpConfigurer::disable) .authorizeHttpRequests(request ->{ request.requestMatchers(antMatcher("/actuator/**")).permitAll(); request.requestMatchers(antMatcher("/**")).permitAll();}) // .headers(header -> header.frameOptions( // frameOptionsConfig -> frameOptionsConfig.disable())) .apply(new MyCustomSecurity()); return http.build(); } public class MyCustomSecurity extends AbstractHttpConfigurer<MyCustomSecurity, HttpSecurity> { @Override public void configure(HttpSecurity http) throws Exception { AuthenticationManager authenticationManager = http.getSharedObject( AuthenticationManager.class); AuthenticationFilter authenticationFilter = new AuthenticationFilter(authenticationManager, userService, environment); http.addFilter(authenticationFilter); } protected void configure2(AuthenticationManagerBuilder auth) throws Exception { auth.userDetailsService(userService).passwordEncoder(bCryptPasswordEncoder); } } } 해당 코드는 앞 내용까지 포함하여 설정이 적용된 버전입니다. 저같은 경우는 처음부터 mysql로 진행하여서 h2 콘솔을 사용하지 않아 frameOptions를 주석처리 하였으나, 혹여나 h2 콘솔 사용하시는 분은 주석 해제 후 사용하시면 되고, 23.08.10 기준으로 hasIpAddress는 사용 불가능합니다.

구상클래스에서 인터페이스 변수를 선언한 이유가 혹시 다형성과 관련이 있나요?

해결됨

나도코딩의 자바 기본편 - 풀코스 (20시간)

클래스의 상속과 관련된 다형성은 부모객체로 인스턴스를 생성하여 부모클래스의 메소드와 자식클래스 메소드 2가지를 업/다운캐스팅하여 자유롭게 호출할 수 있지만, 단일상속이라는 한계 때문에 다른 부모클래스의 메소드는 호출할 수가 없잖아요? 그래서 인터페이스가 존재하는 이유구요. 마찬가지로, 인스턴스를 생성할 때 다형성을 활용하여 인터페이스 객체(부모 객체)로 생성할 수는 있지만, 이것은 ISP(Interface Segregation Principle)원칙에 따라 detect(), report() 2개의 메소드를 호출하려면 Detectable, Reportable 객체 2개를 생성해야 하기 때문에 메모리가 효율적으로 관리되지 못하는거구요. 따라서 구상클래스인 FactoryCam에서 인터페이스 변수를 직접 생성하고 setter함수로 필요한 인터페이스 변수를 주입한 다음(Dependency Injection) , 주입당한 객체는 인터페이스에 의존하기 때문에(Reportable, Detectable) 동시에 기능이 다른 2가지 메소드를 호출할 수 있는거구요.(Dependency Inversion Principle) ... 과정을 이해하였지만 말로 풀어내니까 굉장히 장황하군요 사실 이 부분은 인터페이스 문법이라기보다는 디자인 패턴과 관련이 있지 않나싶습니다.

안녕하세요 질문있습니다.

미해결

Do it! 알고리즘 코딩테스트 with JAVA

방향 그래프 무방향 그래프에 따라서 자료구조에 자료를 저장하는 방법이 다르다고 하셨습니다. 그런데 지금 이 문제에서는 방향그래프 아닌가요?? 간선,엣지들을 보면 모두 방향이 있는 거 같은데, 왜 무방향그래프를 저장할 때처럼 arraylist에 값을 저장하는지 모르겠습니다.

window11 / 23.08.09 기준으로 kafka connect 버전을 7.1 버전으로 사용하시길 바랍니다. 해당 강의의 6.1 버전에서 properties 경로를 못찾아서 버전업을 했더니 해결 했습니다.

docker mysql or mariadb 실행 에러 참고하세요

해결됨

Spring Cloud로 개발하는 마이크로서비스 애플리케이션(MSA)

mariadb 최신버전 사용시 Dockerfile 그대로 작성시 실행 에러가 발생합니다. 저는 sql 을 백업해서 스키마랑 테이블 새로 만들도록 수정해서 해결했습니다. 추가로 실행후 mysql 접속도 mysql 명령어가 아닌 mariadb 로 작성하셔야 됩니다. mariadb -h127.0.0.1 -uroot -p mysqldump -u root -p mydb > mydb.sql FROM mariadb ENV MYSQL_ROOT_PASSWORD test1357 ENV MYSQL_DATABASE mydb COPY ./mydb.sql /docker-entrypoint-initdb.d/ EXPOSE 3306

The request was rejected because the URL contained a potentially malicious String "%0A"

미해결

Spring Cloud로 개발하는 마이크로서비스 애플리케이션(MSA)

UserServiceImpl String orderUrl = String.format(env.getProperty("order_service.url"), userId); user-service.yml order_service: url: http://127.0.0.1:8000/order-service/%s/orders The request was rejected because the URL contained a potentially malicious String "%0A" 실행 중에 해당 에러가 발생했습니다. springSecurity가 버전업 되어 %s같은 것들을 사용하지 못하게 막은 것 같은데 해결 방안을 알고 싶습니다. 정확한 에러는 아래와 같습니다. org.springframework.security.web.firewall.RequestRejectedException: The request was rejected because the URL contained a potentially malicious String "%0A" *spring Security 2.7.12

현업에서 환경변수 같은 건 어떻게 관리하시나요?

해결됨

실리콘밸리 엔지니어가 가르치는 파이썬 장고 웹프로그래밍

민감한 URL 이라든지 환경변수를 통해 사용하고 싶은게 있을 때 강사님께서는 어떻게 관리하시는지 궁금합니다. 그냥 UNIX 환경에서 export url = http://example.com 이런식으로 하고 os 모듈을 통해 쓰고있는데, 더 보안상 좋은 방법이 있을까요?

안녕하세요 강사님 강의 잘 듣고 있습니다. 강의중간에 잠깐 언급하고 넘어가신 부분중에 궁금한게 있어서 질문드립니다. 현업에서 실제로 하루에 10기가 혹은 20기가로 엄청난 양의 데이터가 나올때 이 데이터를 실제로 어떻게 처리하는지 궁금합니다. 감사합니다.

안녕하세요 강사님 Redis Template에 관한 질문입니다.

미해결

실습으로 배우는 선착순 이벤트 시스템

사놓고 안 듣다가 이제 제대로 Redis를 학습해보려고 합니다. Redis Template를 사용하는 방식과 그냥 Repository를 사용하는 방식이 있다고 들었습니다. Redis Template 말고 interface RedisRepository extends CrudRepository<> 쿠폰 발급을 이렇게 정의해서 사용할 수 있나요?
