프로젝트 실행이 안돼요

안녕하세요. hoon님, 공식 서포터즈 y2gcoder입니다.

스스로 잘 해결하셨습니다!

먼저 기존에 보여주신 캡처본을 보면 실행하고 바로 종료된 것입니다. == 정상적으로 실행과 종료를 한 것입니다.

왜냐하면 스프링 부트 애플리케이션에

implementation 'org.springframework.boot:spring-boot-starter-web'

위의 의존성을 추가해줘야 내장 톰캣(웹서버)이 해당 프로젝트에 추가되고, 이 내장 톰캣을 사용해서 웹 어플리케이션으로 띄울 수 있기 때문입니다. 위의 의존성 없이 실행하시면 단순 자바 애플리케이션과 같이 메인 메서드를 실행하고 나서 그대로 종료합니다.

감사합니다.

dependencies {
   implementation 'org.springframework.boot:spring-boot-starter-web'
 } 를 추가하였더니 정상작동합니다 이유가 뭔가요????
