pom.xml을 편집 한 후 스프링 부트 응용 프로그램을 시작할 수 없습니다.

SVN 저장소에서 프로젝트를 다운로드하고 프로젝트를 시작하면 제대로 작동하며 모든 것이 작동합니다. 하지만 pom.xml에 의존성을 추가하고 프로젝트를 시작하면이 예외가 생깁니다.pom.xml을 편집 한 후 스프링 부트 응용 프로그램을 시작할 수 없습니다.

편집 : 내가 서블릿 API를 종속성을 추가하려고하면 가 :

버전을 추가하지 마십시오. 상위 버전이 적절한 버전을 추가하도록하십시오. – helospark

버전을 추가하지 않았지만 문제가 해결되지 않았습니다. – paxie

는 바람둥이 스타터에서 <scope>provided</scope>를 제거합니다.

실행 가능한 jar를 작성하므로 포함 된 Tomcat은 서블릿 컨테이너가 아닌 서블릿 관련 클래스를 제공합니다.
따라서 컴파일 범위가 필요하므로 Tomcat이 빌드 된 jar 파일의 일부가됩니다.

감사합니다. 내 문제를 해결 한 이유에 대해 자세히 설명해 주시겠습니까? – paxie

@ paxie에서 제공하는 범위는 컴파일하는 동안 표시되지만 빌드 된 jar 파일의 일부가 아니며 다른 사람이 제공한다는 의미입니다. 예를 들어 평범한 Spring 애플리케이션에서는 servlet-api가 제공된 스코프에 포함되었습니다.이 경우 독립형 Tomcat이이를 구현했기 때문입니다. 그러나 Spring Boot 애플리케이션에서 임베디드 Tomcat은 구현을 포함하고 있으므로 jar 파일의 일부 여야합니다 (따라서 컴파일 범위가 필요합니다). 'ClassNotFoundException'은 런타임에 클래스를 찾지 못했음을 의미합니다 (jar 파일에 포함되지 않았기 때문입니다). – helospark
