[질문 내용] 현재 강의에서 하고있는 로직은 이미 HTTPservlet에 의해 쓰래드로 돌아가고 있는건가요.? josn클래스에서 username과 age를 사용하는 게 클래스 영역 변수이고, 서블릿은 싱글톤으로 돌아간다고도 기억하고 있어서, 만약 다른 클라이언트가 같은 동작을 요청할 경우 각각 다른 동작을 및 결과를 시행하나요? 항상 강의 잘 듣고 있습니다.

@ExceptionHandler(Exception.class) public final ResponseEntity<Object> handleAllExceptions(Exception ex, WebRequest request){ System.out.println("=====================aop1"); ExceptionResponse exceptionResponse =  new ExceptionResponse(new Date(), ex.getMessage(), request.getDescription(false)); return new ResponseEntity(exceptionResponse, HttpStatus.INTERNAL_SERVER_ERROR); } 강의해주신 내용과 그대로 적용하였는데 메서드가 실행되지 않습니다ㅠㅠ 계속해서 404사 에러만 뜨고 가져온 정보들을 반환해주지않네요ㅠ_ㅠ

현재 App.test.js에는 test()안에 실행중인 코드가 없는 것 같고 test도 react에서만 진행하는데 테스트가 되는게 있나요?테스트를 하여 성공을 하더라도 무엇을 기준으로 성공한건지 잘 모르겠습니다.. 그리고 백엔드 프론트 DB 등등 다양한 컨테이너가 존재하는데 테스트는 리액트만 진행하네요 이게 도커 환경에서 CI로 배포하는 과정까지 큰 틀에 집중하기 위해 test부분 내용은 의도적으로 생략하고 별다른 동작을 안해도 절차를 보여주기 위해 넣은걸로 보면 될까요?? 

안녕하세요! 조훈님께서 제작하신 "컨테이너 인프라 환경 구축을 위한 쿠버네티스/도커"를 구입하여 공부하고 있는 학생입니다. 조훈님과 연락할 방법이 없어서 불가피하게 커뮤니티에 글 남겨봅니다! 다름이 아니라 이 서적의 156p~159p 구간에 ingress yaml 파일들을 도식화가 되어 서적에 기재되어 있는데, 157p의 그림과 159p의 그림이 바꿔진게 아닌가 싶어 이렇게나마 연락드려봅니다. 앤서블 서적부터 항상 여러모로 도움 받고 있습니다! 좋은 하루 되세요!

Qualify나 Primary를 사용해서 주입을하게되면 객체를 바꿔야될때 config파일을 수정하는게 아닌 결국 클라이언트 쪽 코드를 바꿔서 객체를 정하는거니깐 OCP는 못지키는걸로 봐야되나요??

안녕하세요. 나도코딩님 덕분에 강의 따라하면서 파이썬 기초를 열심히 공부하고 있어요. 너무 감사드립니다. 공부하다 궁금한게 생겨 이렇게 질문드립니다. '스타벅스를 예시로 든 00고객님, 주문하신 커피 나왔습니다'를 00고객님, 주문하신 음료 00이 준비됐습니다로 만들어 보고싶어요. 리스트형으로 변수 선언하고 for문으로 반복시킨다는 개념은 이해했는데, 리스트 두개를 만들고 이를 for문으로 한 문장에 어떻게 적용해야할지는 감이 안오네요. '{0}님, 주문하신 음료 {1} 나왔습니다.'.format(customer, menu) 뭐 이런식으로 한다고 치면 앞에 for문을 어떻게 적용시켜야할까요? 질문하면서도 제가 이상하게 질문하고 있는 거 같긴한데... 답변 부탁드릴게요. 감사합니다 :)

Scene뷰 모드를 pivot으로 바꾸면 피벗 포인트는 이동을 할 수 있는데 스트라이프 이미지가 스트라이프 사이즈를 조정하는 핸들(?)을 벗어나 피벗 포인트를 따라 움직여버립니다.  그리고 원래 스트라이프의 rect만 빈 상태로 남아서 피벗 기준으로 돌아갑니다.  강의 보면 피벗 포인트를 움직이면 이미지는 그대로 있고 피벗 포인트만 움직이던데 뭐가 문제일까요?

첫번째 방법으로 푸시는 중에  반복문 시작 인덱스가 1인데, 0부터 시작해야 하는거 아닌가요?

작성 후 실행까지는 잘 되지만 데이터베이스 값을 조회하는 회원 목록버튼을 클릭 할 때와 회원 등록 버튼을 누를경우 오류가 발생합니다. 비슷한 경우가 있는거 같아서 동일하게 수정 해봤지만 오류는 그대로 나와서 질문 드립니다. 답변해주시면 감사합니다.

7강에서 설명해주신 __int__.py 애드온 따라서 작성하고 실행시켜봤는데 Debug Console에 'Debug client attached.' 만 뜨고 등록 해제가 안뜹니다. 블렌더 안 애드온 설정에서도 안뜹니다. 제가 중간에 설정을 잘못해서 생긴 문제일까요??
