실전! 스프링 데이터 JPA
setter를 지양하는 이유 중에 하나가 보안성이라고 생각했습니다. 그런데 builder를 사용하면 똑같이 보안에 문제가 생기지 않나 의문이 들었습니다. 값을 변경하거나 삽입할 때 함수를 따로 만드는 것이 가장 보안성이 좋지만 파라미터가 많을 때 가독성과 편리성을 위해 builder를 사용하는 건가요??

docker의 mysql url localhost:3306/coupon_example에 접속이 안 됩니다. 제 로컬 mysql에 접속이 되는 듯한데 어떻게 하면 docker의 3306 포트의 url에 연동을 할 수 있는지 모르겠네요.. application.yml 파일입니다. spring: jpa: hibernate: ddl-auto: create show-sql: true properties: hibernate: dialect: org.hibernate.dialect.MySQLDialect datasource: driver-class-name: com.mysql.cj.jdbc.Driver url: jdbc:mysql://localhost:3306/test username: root password: 1234

실전! 스프링 부트와 JPA 활용1 - 웹 애플리케이션 개발
'JPA와 DB설정, 동작확인' 수업 중 질문입니다. Test코드는 통과했다고 나오지만 콘솔에는 에러가 뜨고 있습니다. java.lang.ExceptionInInitializerError: null at java.base/jdk.internal.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at java.base/jdk.internal.reflect.NativeConstructorAccessorImpl.newInstance( NativeConstructorAccessorImpl.java:77 ) at java.base/jdk.internal.reflect.DelegatingConstructorAccessorImpl.newInstance( DelegatingConstructorAccessorImpl.java:45 ) 와 함께 Caused by는 Caused by: java.lang.IllegalStateException: MicrometerObservationRegistryTestExecutionListener requires micrometer-observation 1.10.8 or higher at org.springframework.test.context.observation.MicrometerObservationRegistryTestExecutionListener.<clinit>( MicrometerObservationRegistryTestExecutionListener.java:80 ) ... 78 common frames omitted Caused by: java.lang.NoClassDefFoundError: io/micrometer/context/ThreadLocalAccessor 이렇게 나오고 있습니다. 구글링 해보니 spring boot 버전3.0.8에서 간헐적으로 나오는 증상같은데 테스트가 진행됐으니 그대로 해도 괜찮을까요? 아니면 지금이라도 버전 변경을 해야하나요?

토비의 스프링 부트 - 이해와 원리
서버에서 session이 어떤식으로 관리되는지 궁금합니다. 궁금하게 된 이유는 저희가 흔히 인증방식을 jwt token을 쓸 경우 session less때문에 서버에 부하를 줄인다고 알려져 있는데 spring boot를 포함한 다른 서버들도 각 요청마다 HttpServletRequest.session이 담겨져서 오고있고 실제로 컨트롤단에서 사용할 수 있는데 단지 session객체를 참조하지않고 사용한다는 것 만으로 세션을 안쓰기 때문에 서버에 부하를 안준다고 말할 수 있는 걸까요? 제가 생각하는 서버에 부하를 안준다는건, session객체 자체가 생성되지 않아야 부하가 안생긴다는 말이 자연스러울거 같은데, 단지 session객체를 참조해서 쓰지 않는다는 이유만으로 서버의 부하가 없다고 볼 수 있는지 (체감이 될 정도) 궁금합니다. 아마 제가 session에 대한 이해도가 부족해서 드는 궁금함 같습니다. 좋은 강의 만들어주셔서 감사합니다.
