(제가 react-router-dom에 아직 이해를 못한거 같습니다.) 검색페이지에서 검색을 하고 뒤로가기버튼을 누르면 타이핑한 글자 하나 하나씩 뒤로가기가 되는데 이걸 뒤로가기 했을때 바로 그 뒤에 페이지인(현재는 메인페이지로) 이동을 하려면 어떻게 해야 할까요?

main 혹은 controller 등에서 Appconfig를 사용하는 것

해결됨

스프링 핵심 원리 - 기본편

[질문 내용] 질문 게시판에 글을 읽다 보니 public class AppConfig { public MemberService memberService() { return new MemberServiceImpl(); } public MemeberRepository memberRepository() { return new MemoryMemberRepository(); } } public class MemberServiceImpl implements MemberService { AppConfig appConfig = new AppConfig(); MemberRepository memberRepository = appConfig.memberRepository(); @Override public void join(Member member) { memberRepository.save(member); } @Override public Member findMember(Long memberId) { return memberRepository.findById(memberId); } } 위와 같은 코드형식은 MemberServiceImpl이 AppConfig를 의존하는 형식이 되기 때문에 생성자를 사용하여 불필요한 의존관계를 줄인다고 보았습니다. 그렇다면 강의에서 Main 메서드나 Test 코드에서 service를 사용하기 위해 Appconfig를 사용하는 것은 Main 메서드가 AppConfig를 의존한다고 볼 수 있지 않나요? 위에서 얘기한 이유로 MemberServiceImpl에서 AppConfig를 사용하지 않는다면 Main 메서드에서는 왜 AppConfig를 사용하는지 의문입니다.

setFirstResult 와 setMaxResults 적용 안되는 문제

실전! 스프링 부트와 JPA 활용2 - API 개발과 성능 최적화

[질문 템플릿] 1. 강의 내용과 관련된 질문인가요? (예/아니오) 2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? (예/아니오) 3. 질문 잘하기 메뉴얼을 읽어보셨나요? (예/아니오) [질문 내용] orderRepository 파일의 findAllWithItem 함수를 통해 데이터를 불러 올때 setFirstResult 과 setMaxResults 를 통해 페이징을 하기로 코드에 설정하였습니다. 하지만 실제로 api(/api/v3.1/orders?offset=1&limit=10)를 호출해보면 jpa를 통해 만들어지는 쿼리에 offset 및 limit 이 적용되지 않고 날라갑니다. 어떤 문제가 있는지 찾아보았으나 찾지 못하여 질문 올립니다.

프록시 서버 연결 문제

미해결

Node.js로 웹 크롤링하기

이전 질문에도 있었는데 프록시 서버 연결이 안되는데 혹시 이유가 무엇일까요? 코드를 그대로 작성해서 하여도 접속이 안되네요. ip를 1~2개가 아니라 10개 이상을 다른 것들로 해봤는데도 안되서 프록시 서버의 문제보다도 다른 문제가 있는 게 아닐까 싶어서요. (이전 문제들에 답변에는 다른 프록시 서버를 써보라고 하셔서 10개 이상 시도를 해본 뒤 질문드립니다( 다른 사이트의 프록시 서버도 사용해보았습니다) . 포트번호를 넣어서도 해보고 빼보고도 해보고 http도 붙여보고 별 난리를 다 해봤네요) 감사합니다. +) 결과 화면 감사합니다.

Destroy/Active(false,true) 관련 코루틴 질문

미해결

[실전 게임 코드 리뷰] 유니티 클리커 게임

안녕하세요. 코루틴 관련되서 질문이 있어 질문 드리게 되었습니다. 코루틴을 사용할때 GameObject를 SetActive 할 경우 actvie(false)한 뒤 다시 active(true)상태가 되면 코루틴이 작동을 하지 않는 것으로 알고 있습니다. 만약 코루틴을 사용하려고 하는데 active 해야할 GameObject가 있다면 어떤식으로 사용하는 것이 가장 좋은 방법인가요?

강의에서 cross join이 full outer join이라는 설명을 들었는데요 실제로 해보니 cross join은 inner join과 같은 결과를 출력하고 full outer join과는 결과가 다르더라구요. 혹시 뭐가 맞는걸까요?

안녕하세요! 애니메이션 파라미터로 speed를 지정해주고, 코드상에서 setFloat을 사용해서 speed의 값을 이동할 때 10(_speed)으로 변경해줘도 유니티 화면에서는 강사님이 보여주신 것처럼 파라미터 값이 변하지가 않습니다. 왜 그럴까요?

[개정판] 파이썬 머신러닝 완벽 가이드

안녕하세요. 강의 잘 듣고 있습니다. 회귀 실습 1: 자전거 대여(공유) 수요 예측 - 01 10분 49초 시각화 부분에서 질문이 있는데요. Q1 for 문 아래에서 저는 estimator 파라미터에 아래와 같이 mean 을 명시해주고 실행해 봤는데 sns.barplot(data = bike_df, x = feature, y = 'count', estimator='mean' , ax = axe[row][col]) => TypeError: 'str' object is not callable 가 발생합니다. 이유가 뭔가요..? seaborn.barplot 공식 문서에도 estimator 파라미터에 'mean' 으로 적혀있는 부분이 있는데 왜 오류가 나는 걸까요? 답변 부탁드립니다. 감사합니다.

함수 정의할때 질문있습니다.

미해결

프로그래밍 시작하기 : 파이썬 입문 (Inflearn Original)

예제1에서 함수 정의 -> 프린트() -> w1을 word 로 바꾼뒤에 - 그값이 위의 first_func()으로 올라가서 print의 w1값이 goodboy로 출력되는거 같은데.. 그러면 hello ,w1 출력하고 hello goodboy 를 다시 출력하는게 아닌가요? 프로그래밍이 위에서 아래로 내려가는건줄 알았는데 전부 그런건 아닌가보네요 아 쓰다보니 생각이 나는데 혹시 처음 함수 정의때는 w1을 정의 안해줘서 출력이 안되었다가 밑에 정의를 해줘서 hello good boy로 출력되는건가요???

인터셉터 호출

미해결

스프링 MVC 2편 - 백엔드 웹 개발 활용 기술

인터셉터-요청 로그 진행하다 궁금한 점이 있어서요. LogInterceptor 클래스 세팅하고 WebConfig에 WebMvcConfigurer 인터페이스 상속받고 addInterceptors 구현을 하는데요. excludePathPatterns에 /error를 안 넣으면 필터에서는 정상적으로 해당 url이 나오는데 인터셉터에서는 모조리 /error로 url이 나오더라구요 이유가 무엇인지 알 수 있을까요? .excludePathPatterns("/css/**", "/*.ico", "/error");
