포함 된 Tomcat을 시작할 수 없습니다. 봄 부팅

Question

저는 Spring Boot Gradle 응용 프로그램을 만들고 있습니다. booRun을 수행하여 전쟁으로 실행하려고하면 내 응용 프로그램에서 오류가 발생합니다. 오류 메시지 : 묻혀진 바람둥이를 시작할 수 없습니다. build.gradle 파일의 내용 :

아무도 말해 주시겠습니까 내 앱이 임베디드 바람둥이에서 시작되지 않는 이유는 무엇입니까?

감사합니다.

Answer 1

Im 덧글을 남길 수 없습니다. 따라서 임베디드 tomcat을 사용한다면 Tomcat 의존성 (spring-boot-starter-tomcat)이 필요하지 않습니다. 이미 "spring-boot-starter-web"으로 내장되어 있기 때문입니다. 이 종속성을 제거하십시오.

Answer 2

같은 문제가있어서 포트를 변경하여 해결했습니다.

응용 프로그램을 Spring 응용 프로그램으로 실행할 때 일반적으로 관리를 위해 9000 및 9001 포트를 사용했지만 Tomcat에서 실행하려고하면 게시 한 것과 동일한 예외가 발생하여 실패했습니다. application.properties의 두 포트를 모두 8080으로 변경하면 문제가 해결됩니다.
