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? (예/아니오)2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? (예/아니오)3. 질문 잘하기 메뉴얼을 읽어보셨나요? (예/아니오)[질문 내용]프로젝트를 같은 이름으로 새로 생성해서 열려고 하는데 이전에 사용하던 프로젝트가 완전히 삭제가 안 된 거 같아요 .새 프로젝트를 여니까 build 에서 오류가 뜨는데 어떻게 해결해야 할까요

[질문 템플릿]1. 강의 내용과 관련된 질문인가요? (예/아니오) 예2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? (예/아니오) 예3. 질문 잘하기 메뉴얼을 읽어보셨나요? (예/아니오)예[질문 내용]영한님 강의 중 회원 서비스 테스트까지 일단 습득을 하고 있는 중 @AfterEach 이과정에서 MemoryMemberRepository repository = new MemoryMemberRepository();이렇게 하셨지만 원래 인터페이스에서 가져와야한다고 하셔서 MemberRepository repository = new MemoryMemberRepository();인터페이스에서 가져와서 사용 하고 있습니다.돌아가기는 잘 돌아 가는데, 여기서 질문이 노란전구가 뜨면서 alt + enter 했더니 MemoryMemberRepository repository = new MemoryMemberRepository();이렇게 바꾸라고 권장? 하는데요.뭐가 맞는 것일까요??

사용자 정의 ExitStatus를 StepExecutionListener.afterStep에서 정의하는 이유가 궁금합니다.Tasklet 안에서 조건에 따라 contribution.setExitStatus(new ExitStatus("PASS"));를 사용해도 되는게 아닌가 싶은데, 그냥 afterStep에서도 할 수 있다는걸 보여준걸까요? 또, 다음 강의인 JobExecutionDecider 는 사용자 정의 StepExecutionListener.afterStep에서 사용자 종료 코드를 정의하는 것을 대체한다고 생각하면 되는걸까요?

(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.
