안녕하세요강의 잘 듣고 있습니다! 강의해주시는대로 소셜 로그인을 구현했을 때 운영 서버에서도 문제가 없을까요?시큐리티를 활용하는 방법이 너무 많아서, 강의의 내용만으로도 운영서버에 적합한지, 적합하지 않다면 어떤점을 보완해야 할지 궁금합니다!

학습하는 분들께 도움이 되고, 더 좋은 답변을 드릴 수 있도록 질문전에 다음을 꼭 확인해주세요.1. 강의 내용과 관련된 질문을 남겨주세요.2. 인프런의 질문 게시판과 자주 하는 질문(링크)을 먼저 확인해주세요.(자주 하는 질문 링크: https://bit.ly/3fX6ygx)3. 질문 잘하기 메뉴얼(링크)을 먼저 읽어주세요.(질문 잘하기 메뉴얼 링크: https://bit.ly/2UfeqCG)질문 시에는 위 내용은 삭제하고 다음 내용을 남겨주세요.=========================================[질문 템플릿]1. 강의 내용과 관련된 질문인가요?

Member의 @Data를 아래와 같이 바꿨습니다.//@Data @Getter @Setter @ToString public class Member { private String memberId; private int money; public Member() { } public Member(String memberId, int money) { this.memberId = memberId; this.money = money; } @Override public boolean equals(Object o) { if (this == o) return true; if (o == null || getClass() != o.getClass()) return false; Member member = (Member) o; return money == member.money && Objects.equals(memberId, member.memberId); } @Override public int hashCode() { return Objects.hash(memberId, money); } }그리고 MemberRepositoryV0Test에서 equals()에서 일어나는 일을 생각해보았습니다.//findById Member findMember = repository.findById(member.getMemberId()); log.info("findMember.equals(member) = {}",findMember.equals(member)); 1. 첫번째 질문제가 생각했을 때는 Member의 hashCode()에서findMember와 memer가 (memberId, money)가 같으면 같은 hash값을 줍니다.그다음 equals()에서 hash값이 같으면 True를 반환하고 hash값이 없어도 (memberId, money)를 비교하여 같으면 True를 반환해줍니다.제가 정리한게 맞는 지 궁금합니다. 2. 두번째 질문Member에서 equals()를 오버라이딩 안하고 MemberRepositoryV0Test에서 equals를 하면findMember.equals(member) = false가 나오는 이유는 Object.equals()는 내부적으로 ==연산을 취하기 때문이다라고 생각했는 데 이게 맞을까요?? 3. 세번째 질문 저는 isEqualTo()가 대상의 내용자체를 비교한다라고 알고 있었는데 수업시간에 isEqualTo() 내부에 equals()를 포함한다고 배웠습니다.그럼 만약 Object.equals()라면 객체의 주소를 비교 하나요?? 답변주시면 정말 감사하겠습니다.

안녕하세요. 스프링 빈 조회 - 동일한 타입이 둘 이상부분을 듣고있는데, 궁금한 점이 생겨서요 !  AnnotationConfigApplicationContext package hello.core.beanfind; import hello.core.discount.DiscountPolicy; import hello.core.discount.FixDiscountPolicy; import hello.core.discount.RateDiscountPolicy; import org.junit.jupiter.api.Assertions; import org.junit.jupiter.api.DisplayName; import org.junit.jupiter.api.Test; import org.springframework.beans.factory.NoUniqueBeanDefinitionException; import org.springframework.context.annotation.AnnotationConfigApplicationContext; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import static org.junit.jupiter.api.Assertions.*; public class ApplicationContextExtendsFindTest { AnnotationConfigApplicationContext ac = new AnnotationConfigApplicationContext(TestConfig.class); @Test @DisplayName("부모 타입으로 조회시 자식이 둘 이상 있으면, 중복 오류가 발생한다") void findBeanByParentTypeDuplicate() { DiscountPolicy bean = ac.getBean(DiscountPolicy.class); assertThrows(NoUniqueBeanDefinitionException.class, () -> ac.getBean(DiscountPolicy.class)); } @Configuration static class TestConfig { @Bean public DiscountPolicy rateDiscountPolicy() { return new RateDiscountPolicy(); } @Bean public DiscountPolicy fixDiscountPolicy() { return new FixDiscountPolicy(); } } }  위 코드의 findBeanByParentTypeDuplicate 테스트를 실행했을 때, 자식이 둘 이상이고, DiscountPolicy bean = ac.getBean(DiscountPolicy.class); 부분이 있어서 오류가 발생하는 것은 이해했습니다! 그런데, assertThrows(NoUniqueBeanDefinitionException.class, () -> ac.getBean(DiscountPolicy.class)); 이렇게예외를 처리하는 구문이 있는데도, 왜 테스트가 pass 되지 않는 것인지 궁금합니다 !! 에러를 왜 못잡아낼까요 ??

안녕하세요. 현재 저는 jpa를 공부하면서 회원 -> 게시글 -> 댓글을 구현하고 있습니다. 강의를 보고 대략적으로 게시글@many to one (lazy)Member member@one to manyList<Comment> comments = new array 로 구현하였는데 em.find(게시글, id)을 하면member는 다 모든 필드가 다 null인 객체가 들어오고comments는 PersistentBag 객체로 되어 있고 내부에 comment들이 다 들어옵니다. (디버거로 확인하였습니다.)  쿼리를 보니select * from 게시글 where id = idselect * from 댓글 where 게시글id = 게시글id이렇게 두개가 나가더라구요.... 왜 하나는 자동쿼리가 나가고 하나는 안나갈까요?

(예)[질문 내용]안녕하세요. 김영한님의 스프링, 스프링부트 강의를 정말 재밌게 듣고 있는 한 대학생입니다. 강의를 듣던 중에 공부방향에 대해서 궁금한 것이 생겼는데요.이번 웹 계층 개발 파트에서는 특히 js나 css에 대한 내용들이 thymleaf와 함께 많이 다루어지는 것 같습니다.물론 기본적인 html태그들은 그냥 자주 보다보면 외워지겠지만 이런 부분들을 본격적으로 따로 공부할 필요가 있는지 궁금합니다. 나중에 실무에서 제가 DB설계를 하고 도메인, 서비스 계층을 짜는 것은 상상이 되고 지금 공부하고 있는 방향과도 맞는 것 같아서 재밌을 것 같은데,이런 프론트적인 부분? 은 그냥 복붙하고 넘기면 되는지, 아니면 실무에서 제가 실제로 다루게 될 부분일지 경계가 모호한 것 같습니다.정리하자면, 1. 실무에서 백엔드 개발자는 어떤 일을 주로 맡게 되는지, 2. 그래서 이번 웹 계층 파트에서 다루어지는 thymleaf나 js,css, html 내용을 본격적으로 공부해야 하는지 궁금합니다.

18:00 정도에 basicScan() 테스트를 실행하면서 AppConfig 클래스의 OrderServiceImpl의 생성자 관련 오류가 발생한 이유가 궁금합니다. basicScan()에서 ac 를 만드는 과정에 인자로 들어간 것은 AutoAppConfig.class인데 왜 AppConfig 클래스에서 오류가 발생하나요?

[질문 내용]회원서비스개발에서 2:18에1. 무슨 단축키를 누르면 Optional<Member> byName = 이 뜨나요? 저는 그냥 타이핑했는데 어떻게 하면 그렇게 생기죠?2.그리고 단축키 command option v 로 byName을 result로 변경했는데 그것도 단축키를 하면 왜 단축키를 했을 때 수업처럼 옵션이 안뜰까요 3.Optional<Member> byName = 부분 지우고result부분 지우고 코드 정리했을 때 저는.ifPresent부분이 에러가 납니다.4.강의에 4:56 부분 control + t 로 method입력해서 Extract Method 가 뜨는데 저는 안뜹니다.command option m 단축키로 Extract Method를 시도했는데 사용할수없다는데..어떻게해야되나요확인부탁드릴게요...

[질문 내용]안녕하세요 ModelView 의 model 에서 질문이 있습니다.지금 ModelView에서 model인 Map 의 value 값을 Object 형태로 저장하고있습니다. 이를 통해 MemberSaveControllerV3 에서 ModelView 의 model에 데이터를 저장할 때 Member 객체 형태로 저장할 수 있는 것 같은데,이 모델은 MyView 를 통해서 JSP 로 넘어가게될텐데, Object 객체에서 username, age 데이터를 꺼내는게 어떻게 가능한걸까요..? JSP 의 기능중에 이를 가능하게하는 기술이 있는걸까요?

안녕하세요여러개의 변수를 사용 할때는 @RequestParam으로 강의에서 알려 주신 것처럼 Map으로 List 형식으로 밖에 안되나요?감사합니다.
