@ResponseStatus(HttpStatus.OK) @ResponseBody @GetMapping("/response-body-json-v2") public HelloData responseBodyJsonV2() { HelloData helloData = new HelloData(); helloData.setUsername("userA"); helloData.setAge(20); return helloData; } 위에 코드에서는 객체를 리턴하는데 기본값, String이 아니라 뷰 리졸버가 작동하지 않을거 같습니다. 그런데 @ResponseBody를 붙여주는 이유가 궁금합니다.

@RequestBody의 동작과정이 궁금합니다..!HttpEntity를 통해 요청을 받아와서 거기서 .getBody()를 통해 갖고오는게 맞을까요?내부과정을 직접 확인하고 싶은데.. 어떻게 확인해야할지도 알려주시면 감사하겠습니다

 안녕하세요 토비 선생님!강의 너무 재밌게 잘 듣고 있습니다. 이제 몇개 남지 않아서 많이 아쉽네요. 다름이 아니라 테스트 코드 작성시 `@Transactional` 어노테이션의 사용에 대해 질문이 있습니다. 저는 롤백테스트 작성을 위해 @Transactional 을 애용해왔는데요,,얼마전 업무를 보다가 이상하게 테스트 코드는 잘만 통과를 하는데 같은 코드가 서버에 띄웠을때는 의도대로 동작을 안하더라고요. 한참을 씨름하다 알고보니 엔티티를 변경하고 JPA 변경감지로 변경하도록 의도한 코드인데 트랜잭션 경계 밖에서 변경을 하고 있었더라고요.이후로는 찾아보니 테스트 코드에서 @Transactional을 사용하지 말라는 이야기가 많아 안쓰려고 노력을 해보는데 테스트 후 전부 롤백시키는게 만만치가 않더라고요. @AfterEach로 리포지터리를 다 불러와서 하나씩 돌려놓는것도 일이고..개인적으로는 @Transactional 대신에 단순히 전체 테스트에 대해 DB 롤백을 해주는 어노테이션이 별개로 있었으면 더 좋지 않았을까 하는 아쉬움도 있더라고요.스프링에서 굳이 서로 다른 용도의 기능을 하나의 어노테이션으로 공유하는 이유가 있을까요? 트랜잭션 경계라는 점에서는 공통점이 있다지만 각각의 기능으로 분리되었어도 되지 않았을까요?AfterEach 넣어서 리포지터리 하나하나 불러와 일일히 초기화 해 주는 대신 @Transactional 만큼 코드가 깔끔해지면서 테스트코드에 @Transactional을 쓰면 생기게 되는 문제를 해결하는 방법이 있을까요? 혹은 사실 알고보면 테스트에 @Transactional을 쓰는게 좋은건데 제가 잘못 오해하고 있었을까요? 요즘 테스트 코드를 작성할때마다 고민이 많았는데 제가 한동안 검색한 결과로는 쉽게 결론을 내기가 힘들었습니다.더 나은 코드작성에 꼭 도움이 필요해서 실례를 무릅쓰고 질문글을 올려봅니다.감사합니다. 

안녕하세요강의에서는 페이징에 필요한 offset과 limit 값을 @RequestParam을 통해서 넘겨주는 것을 보았습니다. 그런데, 저는 현재 @RequestBody OrderSearchDto를 파라미터로 받아와 내부 필드인 멤버명이나 주문 상태를 검색조건으로 활용하고 있었습니다.이런 경우에는 그냥 @RequestParam을 사용하지 않고, DTO에 offset과 limit 필드를 추가해서 검색과 페이징에 필요한 데이터를 OrderSearchDto 안에 한번에 받는것은 어떤지 궁금합니다.보통 실무에서는 페이징에 필요한 값은 @RequestParam으로 받는 편인가요? 아니면 저의 발상처럼 OrderSearchDto 같은 DTO를 통해 @RequestBody로 받기도 하나요? 일반적인 관점에서 best practice가 따로 있는지 궁금합니다.

저는 testdb 라고 안뜨고url jdbc:h2:mem:a8d68834-99ee-4507-a769-b266691c8e37|이렇게 나오는데, 같은 맥락인가요? --전체 콘솔--/Library/Java/JavaVirtualMachines/jdk-17.0.5.jdk/Contents/Home/bin/java -ea

전반적으로 제가 이해한 내용이 맞는지 궁금해서 질문드립니다.서블릿이라는 것이 검은색 박스안에 있는 것을 다 해주니까 우리는 초록색 박스의 비즈니스 로직에 집중해서 개발을 하고 개발된 것을 war로 빌드해서 was(톰캣)에 배포를 하고 톰캣을 구동을 합니다.그 후 클라이언트가 서버로 요청을 보내면 was 안의 서블릿 컨테이너가 request, responce 객체를 만들어서 서블릿에 넘겨주고 이 객체들을 가지고 서블릿이 비즈니스 로직을 타서 클라이언트가 요청한 리소스를 반환해준다.제가 이해한 흐름이 맞을까요?

 강의를 보면 controller에서 작업을 마무리하고, 이후에 코드를 정리하면서 controller, service, repository로 3단 분리를 하시는데,실제로 처음부터 3단 분리를 하면서 코드를 짜려니까 머리 속에 로직이 잘 정리가 안되더라고요.처음부터 역할에 맞게 분리를 하며 코딩을 하시는지, 아니면 처음에는 머리 속의 로직을 그대로 쭉 코딩하신 후에 나중에 정리를 하시는 편이신지 궁금합니다.

안녕하세요. @Controller, @RequestMapping의 로직에 대해 제가 이해한바가 맞는지 질문드립니다. 다른 분들이 올리신 질문도 다 참고해보고 구글링도 해봤는데 궁금증이 풀리지않아 비슷한 내용의 질문을 드려서 죄송합니다..@Controller, @RequestMapping을 사용해서 애플리케이션을 실행하는 과정에서,서버가 실행되면, @Controller에 의해 핸들러(컨트롤러)로 등록된다.요청이 들어오면, 핸들러 매핑이 핸들러를 찾고 핸들러 어댑터가 핸들러를 실행해야 하는데, 먼저 스프링 내부에 등록되어 있는 RequestMappingHandlerMapping이 핸들러를 조회한다. @RequestMapping을 사용했기때문에 애노테이션 기반 컨트롤러를 조회할수 있는 Requestmappinghandlermapping이 핸들러를 조회하는데, 이때 @Controller로 등록된 핸들러중에 @RequestMapping에 담긴 논리url을 통해 클라이언트가 전송한 url과 매핑을해서 해당되는 핸들러를 조회한다. 그리고 이 조회한 핸들러를 처리할수 있는 어댑터인RequestMappingHandlerAdapter가 핸들러를 호출(process()를 호출)한다. 이렇게 이해하면 될까요?

 시퀀스에서 Cycle을 사용하면 중복키 관리는 안하게 되는건가요?

강의 교재의 "스프링은 스프링 컨테이너에 스프링 빈을 등록할 때, 기본으로 싱글톤으로 등록한다(유일하게 하나만 등록해서 공유한다) 따라서 같은 스프링 빈이면 모두 같은 인스턴스다." 이 문장에서 같은 스프링 빈이면 모두 같은 인스턴스라는 말이 하나의 인스턴스로 자원을 공유한다는 의미 같은데 어떤 경우에 싱글톤을 사용해 자원을 공유하는지 궁금합니다.

강의에서 데이터 베이스를 아직 정하지 못해 인터페이스로 추상화 한다고 설명해 주셨는데 인터페이스 말고 추상 클래스를 사용하면 안되나요? 그리고 만약 데이터 베이스를 정했어도 추상화 할 때 인터페이스를 써야 하는지 궁금합니다.

안녕하세요! 고급편을 듣고 DB2 편을 듣고잇습니다. 여전히 뭔가 이해가 안가서요. 고급원리에도 질문을 하긴했지만 명확하지않았어요. 답변에 DB 2편을 보라고 하셨는데.. ㅠㅠ 이해잘안되네요. 죄송합니다. 궁금한게 뭐냐면,@Tansactional public void externalMethod() { this.internalMethod(); // logic } private void internalMethod() { // logic }여기서 internalMethod는 당연히 트랜잭션이 안탄다고 생각을 했어요. 이유는 우선 DI로 주입이 CGBLIB 프록시가 주입이 되는 것이고 이제 여기서 어노테이션을 보고 프록시 적용을 한다음.프록시 externalMethod 를 불러서 트랜잭션이 탔고internalMethod는 targetMethod 기에 프록시를 안탄다고 생각했거든요?근데 잘타네요.. 이해가 잘안갑니다.. ㅠㅠㅠ--[수정]아 이게.. 프록시 -> 타겟으로 가니까 어떻게보면 당연히 트랜잭션이 먹히는게 맞네요..반대가 안먹히는거고.. 맞죠? ㅠ
