인프런 커뮤니티 질문&답변

안녕하세요 자동 구성 정보 분리쪽 강의를 따라 구현하던 도중 문제가 발생하여 질문을 남깁니다.

return new String[]{
        "tobyspring.config.autoconfig.TomcatWebServerConfig",
        "tobyspring.config.autoconfig.DispatcherServletConfig"
};

직접 경로를 작성해주는 경우에는 문제 없이 동작합니다.

Iterable<String> candidates = ImportCandidates.load(MyAutoConfiguration.class, classLoader);
return StreamSupport.stream(candidates.spliterator(), false).toArray(String[]::new);

클래스 로더를 이용해서 외부에서 파일 경로를 불러오는 방법을 사용하면 아래와 같은 문제가 발생합니다.

제가 생각하기로는 클래스 로더를 통해서 구성 정보를 불러와야 하는데 못 불러오고 있는 것 같습니다.

package tobyspring.config.autoconfig;

import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.boot.web.servlet.server.ServletWebServerFactory;
import org.springframework.context.annotation.Bean;
import tobyspring.config.MyAutoConfiguration;

@MyAutoConfiguration
public class TomcatWebServerConfig {

    @Bean
    public ServletWebServerFactory servletWebServerFactory() {
        return new TomcatServletWebServerFactory();
    }

}

이 문제를 해결하기 위해서

• java 버전 11, 17

• gradle 버전 7.6, 8.0

• Build and run 을 Geadle, IntelliJ

• 파일 경로 수정 등

로 변경하는 방법들을 시도해봤지만 해결하지 못했습니다.

현재 제 개발 환경은 아래와 같습니다.

• IntelliJ버전은 2022.2.3 Community버전

• spring boot 2.7.8

• gradle 7.6

어디서 문제가 발생하는지 감을 잡을 수 없어서 문의드립니다.
