안녕하세요 강의 재밌게 듣고 있습니다 :D 이번 강의 중 테스트에 있어 DI의 장점을 제 나름의 언어로 재정의 해보았습니다. 의존성을 고립시켜 테스트 목적 객체가 아닌 다른 객체의 영향으로 실패할 수 있는 상황을 차단한다. 따라서 DI는 단위 테스트에 대한 신뢰성을 보장한다 라고 이해했습니다. 그런데 이런 생각을 하던 도중 그렇다면 소스코드가 테스트를 의식한 코드를 작성해야 하는 것 아닌가? 하는 생각도 듭니다. 예전에는 이게 싫어서 해당 객체를 상속받은 페이크 객체를 만들어서 테스트 코드에서 의존성을 밀어 넣는 식으로 작성했는데요, 다른 의견들도 찾아보니 소스코드의 안정성을 보장하기 위해 테스트에 의존한 코드를 짜야 한다, 테스트는 소스코드를 위해 존재하는데 소스코드가 테스트에 의존하는 건 자연스럽지 않다, 테스트하기 좋은 간단한 코드를 짜면 이러한 걱정할 필요가 없다 등 여러 의견들이 있는 것 같습니다. 따라서 이에 토비님 의견도 궁금하고 듣고 싶습니다 ㅎㅎ 감사합니다.
안녕하세요 토비님 강의 재밌게 잘 듣고있습니다 :) 흔히들 스프링부트는 톰캣을 스프링 애플리케이션 내에 내장 시켰다는 것에서 가장 큰 차이점을 두고 있는 것 같습니다. 그렇다면 이번 강의 내용에서 서블릿 컨테이너 초기화 작업을 스프링 컨테이너 초기화 작업에 종속 시켰다는 점에서 위에서 언급한 톰캣을 스프링 컨테이너에 내장 시켰다고 볼 수 있을까요? 만약에 제가 질문한 내용이 맞다면 기존에 스프링 부트 없이도 안내해주신 방법대로 내장시킬 수 있었을텐데 보편적으로 내장시키지 않고 분리 시켰을 때의 단점을 가져갔던 이유는 무엇 일까요? 감사합니다.
안녕하세요 선생님 질문이 있습니다. 현재 제가보고있는 commit은 "@ConditionalOnMissingBean을 이용한 커스톰 빈 설정 적용" 입니다. META-INF/spring/tobyspring.config.MyAutoConfiguration.imports 여기에 적힌 TomcatWebServerConfig에서 @Configuration을 지워도 메소드에 @Bean만 있으면 tomcat이 잘 실행이되는것을 확인했습니다. 아예 @Bean까지 다 지우면 jetty dependency도 없으니 기동을 실패하는것을 확인했습니다. 이때 jetty dependency를 추가하면 jetty로 기동하는것도 확인하였습니다. Selector가 JettyWebServerConfig , TomcatWebServerConfig를 load 할때 jetty dependency가 없으면 알아서 메소드 호출을 안하고 있으면 호출해주는것인가요? imports에 적힌 클래스들을 load하게 되면 어떻게 되는지 잘이해가 가지를 않습니다...
안녕하세요 토비님, 정말 좋은 강의 잘 듣고 있습니다. 다만 제가 초보라 그런지 이해하는데 시간이 조금 걸려서 여쭙습니다. 14:00즈음 나오는 diagram에서 OnMyClassCondition이라고 나오는데 아무리 강의를 돌려봐도 OnMyClassCondition은 안보이고 MyOnClassCondition만 보여서 제가 착각을 하고 있는건지 아니면 강의에 오타가 있는건지 궁금합니다. Condition과 MyClass라는 단어가 너무 많이 나와서 혼란스러워서 질문 남긴 것이고, 만약 오타라고 하면 지적할 생각은 아니었음을 말씀드립니다.
BeanPostProcessor는 매개변수가 없는 no-arg 생성자를 필요로 하는데요, 자바의 경우 굳이 매개변수를 생성자에서 주입하지 않아도 되지만 코틀린의 경우 JPA 엔티티나 현재 강의의 ServerProperties처럼 프로퍼티값을 읽어들여 객체를 생성하는 경우 생성자 파라미터를 보통 사용하실 텐데요, 이 경우 따로. noarg 생성자가 만들어지지 않기 때문에 BeanPostProcessor가 디폴트 생성자를 만들어낼 수 있도록 kotlin("plugin.allOpen") kotlin("plugin.noArg")을 이용해서 @Component 어노테이션으로 빈에 대한 no-arg 기능을 활성화해야합니다. gradle에서 다음과 같이 plugin을 포함하시구요 plugins{ kotlin("plugin.noarg") version "1.7.22" //jpa를 사용하신다면 kotlin("plugin.jpa")에 포함되어 있습니다. } 아래에 Component 어노테이션에서 no-arg가 활성화될 수 있게 해당 부분을 적어주시면 됩니다. noArg { annotation("org.springframework.stereotype.Component") } all-open, no-arg 등의 플러그인에대한 더 자세한 설정에 대해서 궁금하시다면 아래 글을 참고하시면 좋습니다. https://techblog.woowahan.com/2675/
안녕하세요. 토비님 강의 너무 잘듣고 있습니다. 강의를 듣다가 궁금한점이 생겨서 질문남깁니다. 우선 저는 독립형 스프링 애플리케이션까지 들었습니다. 강의를 들으면서 스프링과 스프링 부트의 차이점과 이점은 이해가 쉽게 됐습니다. 하지만 서블릿 웹서버와 스프링 웹서버의 차이점에 대해서는 명확하게 이해하지 못했습니다. 독립 실행형 서블릿 애플리케이션으로 웹 서버를 띄우는 것보다 독립 실행형 스프링 애플리케이션으로 웹 서버를 구성하는 것이 어떤 장점이 있는지 궁금합니다. 제가 이해한 바로는 서블릿 웹서버는 HTTP요청이 들어오면 컨테이너가 서블릿을 Mapping하고 서블릿이 요청을 처리하는 것이고 스프링 웹서버는 서블릿에서 스프링 컨테이너를 이용해서 요청을 처리하는 것입니다. 혹여나 개념을 잘못 이해하고 있거나 뒷 내용에 이것에 대한 내용이 나온다면 알려주시면 감사하겠습니다.
토비님. 안녕하세요! 다름이 아니라 '스프링부트의 @Conditional' 항목을 공부하던 중에 conditional() 테스트 코드가 어떻게 동작할지 생각해보았습니다. 저는 true과 false가 1번씩 호출될 것이라고 추측을 했었는데, true가 3번이 호출되어서 생각과는 다른 결과를 확인하였습니다. 제가 무언가를 잘못 알고 있는 것 같아서 확인해보고 싶습니다. 어떠한 키워드로 알아보면 이것에 대해서 알 수 있을까요? 잘려서 보이지 않는 윗부분의 소스 코드는 강의 내용과 다른 점이 없이 작성되어있습니다.

13:48 ~ 13:53 강의 중에 @EnableMyConfigurationProperties( ServerProperties.class ) @EnableMyConfigurationProperties 에 엘리먼트 정의를 안해주셨다고 설명해 주신 뒤 Class<?> 만 치고 강의가 넘어가는 현상이 있습니다.
안녕하세요. 강의를 잘 듣고 있습니다! 다름이 아니라, Bean의 생명주기 메소드 강의에서 마지막 부분이 HelloController의 applicationContext를 생성자 주입하는 코드로 변경하면서 끝이 납니다. 그런데 DI와 단위 테스트 강의에서 HelloController의 테스트 코드를 작성할 때 보여주시는 HelloController.java의 코드를 보면 applicationContext를 생성자에서 파라미터로 받는 부분이 없어져 있습니다. 2개의 강의 사이에서 applicationContext를 파라미터로 받는 코드를 리팩토링하는 부분을 설명해주시는 부분이 제가 찾기에는 보이지 않아서... 혹시 보충 설명을 해주시면 감사하겠습니다.
안녕하세요. 강의 너무 재미있게 잘 듣고 있습니다. 강의 듣다가 클래스 로더를 가져오는 부분에서 의문점이 있는데요(사실 이전부터 개념이 명확하지 않아 어려움이 있었습니다) MyOnClassCondition 만들면서 context.getClassLoader() 이렇게 클래스 로더를 가져왔는데 이렇게 가져오는 것과 this.getClass().getClassLoader() 이렇게 가져오는 것이 어떠한 차이가 있는지 궁금합니다. 둘다 동작은 잘 되거든요. 스프링 부트와 크게 관련된건 아니라고 생각들지만 인터넷 글을 봐도 명확하게 이해가 잘 안되서 초고수 토비님께 문의드립니다. 명강의 감사합니다.!!
cannot acess 에러가 발생하는데, 실제, 코드를 돌리면 컴파일 및 런타임 에러 없이 동작합니다. Access 에러 길래, 접근 제어자 문제로 판단하였으나, 전부 Public 이라 딱히 문제도 없는것 같은데, 저만 그런건지 궁금합니다. registerBean 에서도 해당 클래스를 불러오기 때문에, 여기서도 에러가 뜬다면 이해하겠으나.. 해당 부분은 문제없고.. 밑에서만 떠서... 궁금합니다 [참고로, 실행하면 컴파일 에러 없이 실행 되고... IDE 상에서는 에러로 계속 남아 있습니다. ] package com.example.helloboot; import org.apache.catalina.startup.Tomcat; import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory; import org.springframework.boot.web.server.WebServer; import org.springframework.boot.web.servlet.ServletContextInitializer; import org.springframework.context.support.GenericApplicationContext; import org.springframework.http.HttpHeaders; import org.springframework.http.HttpMethod; import org.springframework.http.HttpStatus; import org.springframework.http.MediaType; import javax.servlet.ServletContext; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.io.IOException; public class HellobootApplication { public static void main(String[] args) { // Spring Container 생성 Context 가 Container 임 // 컨테이너 생성 GenericApplicationContext applicationContext = new GenericApplicationContext(); // 오브젝트 (빈) 등록 applicationContext.registerBean(HelloController.class); // 오브젝트 생성 요청 applicationContext.refresh(); // [Step 1] Servlet 컨테이너 생성 // Factory 생성과 설정 작업등을 대신 해주는 대상 TomcatServletWebServerFactory serverFactory = new TomcatServletWebServerFactory(); WebServer webServer = serverFactory.getWebServer(servletContext -> { servletContext.addServlet("frontcontroller", new HttpServlet() { @Override protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { // 인증, 보안 , 다국어, 공통 기능 등 처리 if (req.getRequestURI().equals("/hello") && req.getMethod().equals(HttpMethod.GET.name())) { String name = req.getParameter("name"); // binding 데이터를 처리하는 오브젝트에 데이터를 넘기는 것 HelloController helloController = applicationContext.getBean(HelloController.class); String ret = helloController.hello(name); resp.setContentType(MediaType.TEXT_PLAIN_VALUE); resp.getWriter().println(ret); } else { resp.setStatus(HttpStatus.NOT_FOUND.value()); } } }).addMapping("/*"); }); webServer.start(); } }
