static 메서드를 사용하는 이유->객체 생성없이 해당 함수(메서드)를 호출해서 사용가능원래는 클래스를 사용하려면 객체를 생성해서 객체로 하여금 공장(class) 내의 기능(함수)를 사용하는 것이 내용이 맞을까요??

안녕하세요 캡틴판교님라우터 네비게이션 가드 강의를 듣다가 next()는 to에서 지정한 url로 이동하기 위한 함수라고 이해했고 위의 next('/login')은 이해가 되는데아래 next()는 to를 어디로 인식하고 이동하게되나요??

안녕하세요 캡틴판교님 제가 저번에도 질문드린 적이 있는데 이해가 잘안되서 다시 질문드려요강의에서는 import store해서 가져온다음 && store.getters.isLogin으로 사용하는데위와 같이 사용하면 작동이 안되나요??this.$store 도 store안에있는 무언가를 가져오는 코드구문이 아닌가요??store와 $store의 차이를 잘 모르겠어요 너무 궁금합니다.

서버쪽 bearer-token.guard.ts 쪽에서 토큰으로 유저정보 만드는 부분에 아래처럼 sub으로 유저정보를 검색하는데 sub이 user id이더라구요.. 그래서 user 값이 제대로 조회가 안되서 에러가 발생했었습니다.request.user = await this.userService.findByUsername(payload.sub);일단 payload.username으로 검색하게 하니 잘되는것 같습니다~

강의대로 인스타그램 클론까지 작성후앱을 실행해서 테스트를 진행하려고하는데앱[Flutter]아이콘이 안보입니다..혹시몰라서 강의목차중 '안드로이드 에뮬레이터 설치 및 데모 앱 실행' 강의를 듣고 따라해보니화면이 다르게 보입니다. 강의 화면은 데모앱이 실행되는데제화면은 안드로이드가 실행되어버리며 강의에 나오는 앱[Flutter]아이콘이 안보입니다.*환경 : Windows프로그램 : 안드로이드 스튜디오*에뮬레이터 실행후 상단에서 선택후 실행시 아래와 같은 오류가 발생하네요..

 안녕하세요.위 파일은 product.entity.ts 파일입니다.product.entity.ts 파일에서 @JoinColumn() 을 productSaleslocation 테이블에만 해주시는 이유가 무엇인지 알 수 있을까요?product테이블과 서로 관계를 맺고 있는 productSaleslocation 테이블과 users 테이블에도 @JoinColumn()을 해줘야 하는 것 아닌가요?상품테이블은productCategory테이블과(상품카테고리_id)ManyToOne 관계를 맺고 있으며, User 테이블과 (유저_id) ManyToOne 관계를 맺고 있어서 각각 JoinColumn을 해줘야 하는 것으로 생각했는데,  제 생각이 틀린 것일까요?좋은 강의 해주셔서 진심으로 감사합니다!

처음에는 태그 자동완성도 되고 리로드도 정상적으로 실행됐습니다.그런데 수강 중 실습하면서 코딩 작성하다가 알림창이 떠서 확인도 안하고 클릭했더니다음부턴 태그 자동완성도 안되고, 웹브라우저로 리로드하면 원본 코드 그대로 나타납니다...visual studio code 삭제 이후 재설치해봤는데도 똑같은 상태라서 어떻게 해야할지 모르겠습니다.

안녕하세요...아래 강의를 듣고 있는데요..현재 강의내용을 대략적으로 반영한 교재가 있는지 궁금합니다.제가 검색해 본 교재들은 모두 기본 이론(블렌더 기본조작방법)을 간단히만 소개하고,예제만들어보는 데 지면을 많이 활용해서 실제 전체적인 블렌더 기본조작방법을 배우기 어렵습니다.그래서 현재 강의 내용을 요약식이라도 반영한 교재나 자료가 있으면 구하고 싶습니다.Blender(블렌더) 3.0 3D 그래픽의 입문 Part. 2

data task가 정확히 무엇인가요?강의를 여러 번 돌려보는데 정확한 설명이 안 나오는 것 같아서요..

안녕하세요 김영한 강사님의 강의를 듣고 개인 프로젝트에 JPA를 정말 잘 사용하고 있습니다.JPA를 사용해서 개발을 하다 보니 JPA를 사용하기 전과 다르게 확실히 객체의 역할을 분리해서 만들 수 있었고 동일 트랜잭션 내에서 영속성 엔티티 객체를 활용하여 DB 통신을 최소화할 수 있었습니다.그러나 동일한 트랜잭션 내에서 모든 비즈니스 로직을 끝내도록 설계를 하다 보니 서비스 클래스 내에서 다른 서비스 클래스를 사용해야 하는 상황이 빈번히 생겼습니다.그렇게 무턱대고 서비스 클래스에서 DI를 남용하다 하여 서비스 클래스 간 순환 참조 상황이 벌어지게 되었습니다.문제를 해결하기 위해 spirng DI 대해서 공부를 하였고 설계가 잘못되었다는 걸 알게 되어 2가지 해결 방법을 생각해 봤습니다.첫번째 해결방법:컨트롤러를 거쳐서 순차적으로 서비스 로직을 수행하는 방식이었지만JPA를 사용하기 때문에 동일한 트랜잭션 내에서 처리하지 않으면 영속성이 해제되어 다시 DB를 참조해야 하는 상황일뿐더러컨트롤러는 http 파라미터를 검증하고 사용자에게 원하는 정보만 전달한다는 컨트롤러 객체 역할의 기준이 모호해질 것 같았습니다.컨트롤러에서 트랜잭션을 걸 수 있도록 설정하는 방법을 알아봤지만 위험성이 존재한다고 들었습니다.두번째 해결방법:조회만 하는 Service 클래스,현재 데이터를 검증하여 저장, 변경하는 객체를 실행하는 클래스 등입출력을 동시에 하는 서비스 객체를 분리하거나검증하는 과정의 로직을 따로 분리하여 단 방향으로 흐르게 재설계 했습니다.분리하게 되면서 검증 클래스 같은 경우 추후에 여러 서비스에서 다양한 검증 로직이 필요하게 되면 인터페이스화하여 공통 검증 기능으로 사용할 수 있는 다형성까지 생각해 볼 수 있게 될 것 같아서 현재 이 방법으로 리팩토링하였습니다.아직 실무를 겪어 보지 못한 취준생이라 제가 해결 한 두번째 방법이 맞는 건지 불안합니다.아니면 에초에 설계가 잘못되어 다시 구성을 해야 하는 상황일까요??
