김영한 강사님 스프링 입문 View 환경설정 파트 7:58 부분 질문 드립니다.강사님 강의를 그대로 따라 했는데 아래 이미지와 같은 오류가 발생하여 진행이 막힌 상태 입니다. 해당 오류를 구글링으로 찾아보았으나 해결법을 얻지 못했습니다. 다음 수업으로 진행을 위해 해당 오류 해결법을 요청드립니다.

[질문 템플릿]1. 강의 내용과 관련된 질문인가요? 예2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? 예3. 질문 잘하기 메뉴얼을 읽어보셨나요? 예[질문 내용]최근 복습을 진행하며 자동 빈 등록, 수동 빈 등록에 관해 스스로 이것저것 해보다가 궁금한게 있어 질문 드립니다. 우선 AppConfig.class입니다.package com.example.asdfsadf.test; @Configuration public class AppConfig { private OrderService orderService; @Autowired public AppConfig(OrderService orderService) { this.orderService = orderService; } @Bean public OrderRepository orderRepository() { return new MemoryOrderRepository(); } }AppConfig.class에는 OrderService를 생성자 주입을 받고 있고, 수동으로 OrderRepository를 빈으로 등록하였습니다. 그리고 같은 패키지에 AppScanConfig.class를 두었습니다.package com.example.asdfsadf.test; @ComponentScan public class AppScanConfig { } 마지막으로 OrderService는 AppScanConfig에 의해 자동 빈 주입 받습니다.@Component public class OrderServiceImpl implements OrderService { private final OrderRepository orderRepository; public OrderServiceImpl(OrderRepository orderRepository) { this.orderRepository = orderRepository; } } 이때, 다음과 같이 단순히 AppScanConfig 정보를 바탕으로 컨테이너로 생성하도록 테스트 하였습니다.class appConfigTest { @Test public void test() { AnnotationConfigApplicationContext ac = new AnnotationConfigApplicationContext(AppScanConfig.class); } }결과는 다음과 같은 오류가 발생했습니다."C:\Program Files\Java\jdk-11.0.10\bin\java.exe" -ea -Didea.test.cyclic.buffer.size=1048576 "-javaagent:C:\Program Files\JetBrains\IntelliJ IDEA 2022.1.3\lib\idea_rt.jar=59805:C:\Program

(필드 주입으로 하더라도 AppConfig의 이름을 zAppConfig로 해서 패키지의 가장 아래에 놓이게 해도 에러가 발생합니다.) 제가 생각한 오류 원인은 이렇습니다.AppScanConfig를 설정 파일로 지정했기 때문에 가장 먼저 빈으로 등록패키지의 가장 위에 있는 @Component 클래스인 AppConfig를 빈으로 등록AppConfig를 빈으로 등록하는 과정에서 생성자 주입으로 OrderService를 빈으로 등록하려함OrderService를 빈으로 등록하려고 봤더니 OrderRepository를 의존하고 있어서 OrderRepository를 빈으로 등록하려함OrderRepository를 빈으로 등록하기 위해서 AppConfig에 접근AppConfig는 OrderService를 의존하고 있어서 OrderService를 빈으로 등록하기 위해 이동...-> 순환 참조 문제라고 생각했습니다.  하지만 OrderRepository만 빈으로 등록하면 될 문제 같은데 위 상황에서 왜 되지 않는건지 명확하게 이해가 가지 않아서 질문드립니다! 어떤 문제 때문에 에러가 발생하는 걸까요 ??

IP랑 Username 도 맞게 넣은 것 같고 인바운드 규칙도 편집했습니다. mysql vi 에서 bind-address도 주석처리했습니다. 무엇 때문에 걸리는 지 구글링해도 원인을 찾지 못하겠습니다. 한 가지 걸리는 게, 저 창에서 user?이름인 맨 앞에 이름이 root 가 아닌 ubuntu로 되어있어서 주석 처리 할 때 계속 오류가 떠서 명령어를 다르게 해서 했는 데 이게 문제가 될까요? workbench에 Username에 root가 아닌 ubuntu 해봤음에도 안됩니다.

해당오류가 뜨며 열리지 않습니다 ㅠㅠsever1 전원을 끄고 실행해도 마찬가지인 상황을 확인했습니다. 어떻게 해결하면될까요 ..??

지금현재 맥을 사용하고있고 에로부분을 확인한결과 JDK11버젼을 설치하라나오는거 같은데 main에서 run실행이안되고 코끼리 버튼도 눌러봤는데 에러가 나옵니다 ㅜㅜ머땜에 그러는지 도저히 알수가없네요 ㅜA problem occurred configuring root project 'hello-spring1'.이런식으로 에러가 납니다

안녕하세요. virtual box에서 ubuntu-20.04 버전 설치 후 터미널 실행을 해도 터미널이 열리지 않습니다.open in terminal이나 직접 터미널을 실행해도 열리지 않습니다. 서칭을 했는데 잘 해결되지 않아 질문드립니다.혹시 관련 이슈에 관해 해결할 수 있는 방법이 있다면 공유해 주시면 감사 드리겠습니다. 

안녕하세요, 맛비님!다름이 아니라 vivado를 이용하여 led 점등하는 코드를 따라서 입력하고 RTL Schematic을 확인하려고 RTL ANALYSIS의 Schematic을 누르니 로딩이 되다가 vivado창이 닫혀버립니다...혹시 원인을 알 수 있을까요? Vivado는 버전22.1을 사용 중이고, 관리자 권한 실행도 해본 상태입니다.

강의 대로 따라했는데 강의에서도 보면 플레이어 피가 0이하가 되어도 몬스터가 계속 때리더라구요 근데 몬스터 컨트롤러 OnHitEvent를 보면 targetStat.Hp > 0 때의 else는 targetStat.Hp <=0 이니깐 플레이어가 체력이 0이하가 되면 몬스터는 Idle 상태가 돼야하는거 아닌가요? 왜 계속 때리는건가요?

node js 깔고, 터미널에 'npx create-next-app@latest' 설치한 다음에 pasge 폴더에 있는 거 다 지우고 index.js 파일 새로 생성해서 코드 짜넣어도 npm run dev가 동작하는데 상관 없나요?

안녕하세요 선생님, 마구간 문제 관련하여 잘 이해가 되지 않는 부분이 있어 이렇게 글 남겨드립니다. count 함수를 통하여 말의 개수를 셀 때, 좌표의 가장 왼쪽, 즉 좌표 배열을 arr이라고 하면,선생님께서는 count 함수에서 말의 개수를 세실 때, arr[0]을 ep로 두어 for문으로 문제를 해결하셨는데요, 이 부분이 직관적으로 확 와닿지 않습니다 ㅠㅠ.. 마땅한 반례를 찾지는 못하였으나, arr[0] 이외의 부분에서 답이 있을 수 있으니, ep를 이중 for문으로 돌려 찾아야 하는 것이 아닌가 생각이 드는데, 그렇게 하지 않으신 이유에 대하여 질문 남겨드립니다 감사합니다 선생님!

cors({ origin: true }) 했을시에는Access-Control-Allow-Origin 이 '*' 이 아닌 http://localhost:3001 이렇게 요청보낸 곳의 url 로 나오는데, 특별한 이점이 있나요? 단순히 사용자에게 cors({ origin: '*' })이 아니다 라고 알려주는게 목적인가요?

sql injection이 성공한다면 매우 위협적이라는 것은 알고 있으나 강의 내용을 수강하고 나서 든 생각은 매우 간단한 조치(prepared statement + 길이제한 + white List)만으로도 취약점 분석 단계에서 막혀버리는 공격인데 왜 owasp top 10에 들어갈 정도로 위협적인 공격으로 평가되고 있는지 궁금합니다.

count(*)의 의미는 아는데 >1을 하는게 어떻게 유니크한 값을 볼 수 있는건지 이해가 안됩니다
