안녕하세요 강사님. 참 좋은 강의 감사드립니다.예제 고도화 과정에 Request DTO nullable 필드 처리에 어떤 방식이 적절할 지 알수 없어 남기게 되었습니다.Kotlin 객체 필드타입을 크게 두 방식으로 선언 할 수 있습니다.nullablenon-null코프링 기반에서 Request DTO 의 경우,객체필드를non-null 타입으로 선언하면 WebMvc 와 spring-validation 을 함께 사용하면, 발생 가능한 가설을 세워보았습니다.문제:서버 요청에 '비 유효값'`[공백문자["", ' '], null 필드값, 공백 JSON( {} )]`이 넘어올 때, Kotlin 언어의 non-null 타입 속성은, sprint-validation 절차를 거치지 못함. 원인:1. 속성 타입을 non-null 타입 선언 후 컴파일 시 Intrinsics.checkNotNullParameter(field, "field"); 함수가 non-null 검증코드로 DTO 생성자 함수 본체에 추가.2. 앞선 checkNotNullParameter 함수는 DTO 생성을 원천 차단.3. 때문에 Kotlin non-null 검증이 spring-validation 검증 이전에 수행됨을 뜻함. 즉, 검증 대상이 생성이 되어야 spring-validation 절차를 거칠텐데, 검증 대상이 없는 상황이 된다.(이 부분은 저의 뇌피셜이 포함되었으므로 검증되지 못한 분석결과 입니다) 이 문제에 대해 다음의 해결 방법을 생각할 수 있습니다.field 타입을 nullable 하게 선언, 기본값 null 설정data class UserCreateRequest( @param:JsonProperty("email") @field:NotBlank @field:Email val email: String? = null, ⬅️`?`및 기본값 설정 ) { fun toCommand() = UserCreate( /* String ❌ String? 미스매치 */ email = email!!, ✅단언 해결 ) }이 방법은 단언 !! 을 사용하여 전적으로 spring-validation 의 검증에 전적으로 의지하는 코드입니다.의문점은 개인적으로 우아하지 못한 단언 !! 을 꼭 사용해야 할까? 인데요, 다른 방법으로는,Backing 필드 생성자 선언 ➡️ 커스텀 getter 로 Backing 필드값 반환이 떠오르는데요, 이것 또한 보일러-플레이트 코드량이 늘어나서 우아하지 않아 보입니다^^;강사님의 경우에는 어떠한 해결방법을 사용하지는지 궁금해서 질문 남겨보았습니다.읽어 주셔서 감사합니다.

제가 이해한바로 age 필드는 primitive type이기 때문에 default value가 0으로 설정되어 다소 모호한 결과값이 나올 수 있기 때문에 withIgnorePath를 통해 특정 필드를 제외하는 것으로 이해했습니다. primitive type의 default value가 0이기 때문에 모호한 결과값이 나올 수 있어서 제외하는거라면 아예 공식 문서상에서도 이 기술을 사용하는 경우 엔티티를 Integer 객체로 생성하도록 권장하고 기본값으로 not nullable한 필드는 기본값으로 exclude하는 방법도 좋았을 것 같은데 이렇게 설계가 된 이유가 있을지 궁금합니다! reflection을 이용하면 가능할 것 같은데 다른 경우의 수가 있어서 그런걸까요?

Transition - on() / to() / stop(), fail(), end(), stopAndRestart() 강의 질문입니다. 강의 31분 35초 강의교안 아래쪽에 Step1()의 ExitStatus에 따라서 메타 테이블의 상태를 비교하는 내용이 있는데요.왼쪽, Step1()에서 ExitStatus를 FAILED로 세팅하면, batch status는 ABANDONED가되는데요.오른쪽, Step4()에서 (코드는 없지만) ExitStatus를 FAILED로 세팅했을 때는 batch status가 FAILED로 나와있는데. 정확히 batch status가 ABANDONED과 FAILED로 세팅되는 차이점은 무엇인가요?(강의를 듣는 도중에 작성하는 질문이라서...다른 강의에서 나오는 주제면 알려주시면 계속 강의를 보도록 하곘습니다.)

[질문 템플릿]1. 강의 내용과 관련된 질문인가요? 예2. 인프런의 질문 게시판과 자주 하는 질문에 없는 내용인가요? 예3. 질문 잘하기 메뉴얼을 읽어보셨나요? 예[질문 내용]수업 잘 듣는 중입니다. 다름이 아니라, 강의에 나온 jdbc 코드를 얼마나 알아야 하는지 궁금합니다. 저는 Mysql로 연동홰서 사용중인데, 순수 JDBC 강의에서 나온 데이터 CRUD 코드를 얼마나 알아야할까요? 대표적으로 알아야하는 코드가 있다면 알려주시면 감사하겠습니다.

안녕하세요 ! 강의 너무 재밌습니다 감사합니다.. (2:29)Notifications 앞에 @Valid 을주셨는데 막상 Notifications 객체에는 벨리데이션 조건도없고 @InitBinder도 따로 없는데@Valid 붙이는게 의미가 있는건가요 !?! 제가 궁금한건 @Valid 이 어노테이션이 유효한지가 궁금합니다. 

FlowJob - 개념 및 API 소개 강의 질문드립니다.Step1이 실패했을 경우 Step2를 실행하도록 한 것은 이해했습니다.Step1을 실패시키더라도 Step2까지 실행이되며 Job도 COMPLETED 상태인 것 도 이해했습니다.근데 여기서, 똑같은 JOB을 실행하면 Job Instance가 이미 존재한다는 예외가 아닌 Step already complete or not restartable, so no action to execute: 이라는 메시지가 나오는데요. 이제까지 알기론 Job Execution이 실패한 경우에만 같은 job 파라미터로 실행할 수 있는 걸로 알고 있는데요.FlowJob의 경우는, Job Execution이 COMPLETED 상태여도 StepExecution까지 확인하는건가요?

강의와 같이 ApiModel어노테이션을 달아보려해도 아래와 같이 어노테이션이 뜨지도 않고 다 입력을 해보아도 오류만 뜰 뿐입니다 ㅠㅠ 저 같은 분 있으신가요?

 안녕하세요!강의 잘 듣고 있습니다! steps 클래스를 따로 만드는 이유는 뭐라고 할 수 있을까요?? 감사합니다.

질문이 하나있습니다.8:48인데요  @PostMapping(SETTINGS_PASSWORD_URL)public String passUpdate(@CurrentUser Account account, @Valid PasswordForm passwordForm, Errors errors,Model model, RedirectAttributes attributes){System.out.println("errors : " + errors);if(errors.hasErrors()){ model.addAttribute(account);return SETTINGS_PASSWORD_URL;} 이부분인데 에러가 났을때 왜 model.addAttribute(account); (66라인)모델이 다시 담아주는건가요 ??  ==================================== 다시 생각해보니 account 객체가 nav-bar 에서 필요해서(account 객체에 따른 이미지 보여주기) 다시 담아주는거 같네요 

왼쪽이 spring-boot-starter, 오른쪽 spring-boot-getting-started입니다.둘다 패키지 이름은 me.gang으로 똑같고 수업과 똑같이 따라하면 started 프로젝트에서 holoman클래스를 찾을수 없다고 나옵니다. 어떻게 해야 해당 에러를 해결할 수 있나요?

요청을 한번 보냈는데, 다시 한번 요청이 와서, filterchainproxy에 요청 위임하는 과정이다시 나오는데 어떤 이유에서 그런건지 궁금합니다

안녕하세요. 강사님의 강의를 듣고 개인 프로젝트에 적용하고 있습니다.LocalDateTime이 없을 때는 잘 수행되었는데 제 개인 프로젝트 엔티티에는 LocalDateTime이 있습니다. 이 부분에서 자꾸 에러가 나와서 어떻게 처리해야 하는지 알려주시면 감사하겠습니다. 다음은 제가 LocalDateTime을 처리하기 위해 따로 만든 엔티티 입니다.package com.dotd.product.kafkaConnectTest; import jdk.jfr.Name; import lombok.AllArgsConstructor; import lombok.Builder; import lombok.Data; import lombok.NoArgsConstructor; import org.springframework.data.annotation.CreatedDate; import org.springframework.data.jpa.domain.support.AuditingEntityListener; import javax.persistence.*; import java.time.LocalDateTime; @Entity @Data @NoArgsConstructor @AllArgsConstructor @Builder @Table(name = "nametest") @EntityListeners(AuditingEntityListener.class) public class NameTest { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Integer id; private String name; @CreatedDate @Column(name = "created_at") private LocalDateTime createdAt; }   또한, Kafka Connect Sink가 한 번 에러가 발생하면 state : FAILED로 바뀌면서 작동을 안 하는 거 같은데 어떻게 정상화 하나요..?? 127.0.0.1:8083/connectors/nametest-sink-connect/status이 요청을 보냈을 때 이렇게 나옵니다.  { "name": "nametest-sink-connect", "connector": { "state": "RUNNING", "worker_id": "192.168.0.14:8083" }, "tasks": [ { "id": 0, "state": "FAILED", "worker_id": "192.168.0.14:8083", "trace": "org.apache.kafka.connect.errors.ConnectException: Exiting WorkerSinkTask due to unrecoverable exception.\r\n\tat org.apache.kafka.connect.runtime.WorkerSinkTask.deliverMessages(WorkerSinkTask.java:611)\r\n\tat org.apache.kafka.connect.runtime.WorkerSinkTask.poll(WorkerSinkTask.java:333)\r\n\tat org.apache.kafka.connect.runtime.WorkerSinkTask.iteration(WorkerSinkTask.java:234)\r\n\tat org.apache.kafka.connect.runtime.WorkerSinkTask.execute(WorkerSinkTask.java:203)\r\n\tat org.apache.kafka.connect.runtime.WorkerTask.doRun(WorkerTask.java:189)\r\n\tat org.apache.kafka.connect.runtime.WorkerTask.run(WorkerTask.java:244)\r\n\tat java.base/java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:515)\r\n\tat java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264)\r\n\tat java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128)\r\n\tat java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628)\r\n\tat java.base/java.lang.Thread.run(Thread.java:834)\r\nCaused by: org.apache.kafka.connect.errors.ConnectException: java.sql.SQLException: Exception chain:\r\njava.sql.BatchUpdateException: Column 'created_at' cannot be null\r\n\r\n\tat io.confluent.connect.jdbc.sink.JdbcSinkTask.put(JdbcSinkTask.java:124)\r\n\tat org.apache.kafka.connect.runtime.WorkerSinkTask.deliverMessages(WorkerSinkTask.java:581)\r\n\t... 10 more\r\nCaused by: java.sql.SQLException: Exception chain:\r\njava.sql.BatchUpdateException: Column 'created_at' cannot be null\r\n\r\n\tat io.confluent.connect.jdbc.sink.JdbcSinkTask.getAllMessagesException(JdbcSinkTask.java:154)\r\n\tat io.confluent.connect.jdbc.sink.JdbcSinkTask.put(JdbcSinkTask.java:104)\r\n\t... 11 more\r\n" } ], "type": "sink" }

(예)[질문 내용]여기에 질문 내용을 남겨주세요.해당 강의를 따라하던 중 오류가 도무지 해결되지 않아 질문글 남깁니다. 우선 저의 소스코드를 남기겠습니다.build.gradleMemberMemberRepositoryMemberRepositoryTest에서 A component required a bean of type 'jakarta.persistence.EntityManagerFactory' that could not be found. 오류가 발생합니다. SpringBoot에 일단 부딪혀보고자 시작한 강의라 아무리 구글링해봐도 어떻게 해결해야할지 막막합니다. build.gradle에서 MVCC=TRUE를 제거해봐도,build.gradle에 아래 코드를 추가해봐도,testImplementation 'com.querydsl:querydsl-jpa:5.0.0:jakarta'jakarta.persistence.EntityManagerFactory를 import해봐도,MemberRepositoryTest에 @ContextConfiguration(classes = MemberRepository.class)를 추가해봐도 해결할 수가 없었습니다. 버전이 맞지 않아서 생기는 부분이라면 처음부터 다시 진행하도록 하겠습니다. 도와주십쇼. 이하 오류 내용 전문입니다.C:\Users\User\.jdks\corretto-17.0.8.1\bin\java.exe -ea -Didea.test.cyclic.buffer.size=1048576 "-javaagent:C:\Program

spring boot 3, java 17 버전사용하고 있습니다

먼저 저번에 스프링 시큐리티 1편 강의를 듣고 전체적인 인증흐름 등 소개가 만족스러워서 이번에 oauth2 도 샀습니다. 단도직입적으로 얘기하면(OAuth2의 인증흐름+RESTAPI 식으로 OAuth2)를 어떤 식으로 코드를 짜는지 보고 싶습니다. 이에 대해 도움이 되는 강의 chapter를 먼저 수강하고 싶습니다. 학기 중이라 44시간을 듣기 좀 부담스럽기도 하고 한번 oauth2의 인증흐름+restAPI 식 oauth2를 먼저 구현하고 난 후에 다시 강의를 들을때 꼼꼼히 들을 예정입니다그래서 질문은1)(OAuth2의 인증흐름+RESTAPI 식으로 OAuth2)에 관련된 chapter를 소개해 주실수 있을까요??(예를 들면 MAC 등 이런 것은 제외하고요..)2)이거 쓰다가 궁금해지는게 소셜로그인-Form Login 을 수강하면 RESTAPI 식으로 바꾸는 것은 별차이가 없을까요?  

aws 로 서비스 배포하였는데 버튼눌러서 controller에 접근하는 url이 바뀔떄마다 엄청 느려서 기능접속이 잘안되네요 swap설정은 되어있는데 혹시 이유알수 있을까요 ??url을 직접쳐서 검색하는건 빨라요간단히 controller에서 template으로 정보 맞교환하는건데 이유 알수 있을까요? <!DOCTYPE HTML> <html xmlns:th="http://www.thymeleaf.org"> <head> <title>Hello</title> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <link rel="stylesheet" href="../css/main.css"/> </head> <body> <div class="cd-switch"> <div class="switchUp"> <h1> <p th:text="${userName}+'님의 선택은 !?

계속하여 아래와 같이 getNo()을 인식하지 못하는 오류가 발생하고 있습니다.Method getNo() cannot be found on type com.example.demo.v2_VO.VO.Order_list 그래서 한참을 해맨 후에 vo의 @Data가 Getter의 기능을 하지 못하고 있는 것을 알게되었습니다.일일이 getter를 만들어주니까 돌아가더라구요... 그래서 lombok의 문제로 생각하고 롬복을 설치하고 외부 라이브러리를 추가해주는 식으로 해결하려고 하였습니다. 이렇게 조치를 해도 계속 오류가 나더라구요.. 혹시 김부장님께서는 이런 경우 다른 방법으로 문제를 해결하신 적 있으신가요?

윈도우 환경에서 gardle을 빌드 시키려고 하면org.gradle.api.UncheckedIOException: Could not load properties for module 'gradle-cli' 이 오류가 뜹니다 인텔리제이 재설치,스프링 재설치,vscode로 실행등을 다 해봐도계속 저 오류가 뜹니다인텔리제이 재설치 이후에는 Unable to load class 'org.slf4j.LoggerFactory'.This is an unexpected error. Please file a bug containing the idea.log file.가 뜹니다

안녕하세요.아직 앞부분이지만 강의 최고입니다. 질문1테스트코드 인증 메일 확인 - 입력값 오류에 대해서 지금 로직은 이메일 자체가 없으니까 이메일이 없는 오류고 이메일은 존재하나 토큰이 일치 하지않는경우 이렇게 2가지로 테스트 코드를 진행할 필요까진 없는건가요 ? =================================질문25:45 초에는 @Transactional 을 달아주셨는데 이 이유가58 라인에 있는 newAccount.generateEmailCheckToken(); 코드를 영속객체로 관리 해주기 위함 이라고 생각하면 될까요?
