Spring Boot 2.3.0 이후버전에는 AnnotationException이 발생하지 않습니다.

Question

2.2.8 버전으로 낮췄을 때는 이렇게 오류가 나면서 스프링이 종료가 되는데, 2.3.0 버전 이후에는 오류가 발생하지 않습니다. Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled. 2020-06-18 21:08:41.809 ERROR 22277 --- [ main] o.s.boot.SpringApplication : Application run failed

찾기가 쉽지 않네요. https://mvnrepository.com/artifact/org.springframework.data/spring-data-jpa/2.2.8.RELEASE https://mvnrepository.com/artifact/org.springframework.data/spring-data-jpa/2.3.0.RELEASE 문제점을 버전을 내려서 확인하고 소스는 정상동작 하는 상태입니다. 졸면서 하다가 ㅠㅠ 엉뚱한데에 소스를 넣었었네요.

김영한 · Answer

우선 해결은 하셨군요^^ 혹시 제 도움이 더 필요하시면, 동작하는 버전과, 동작하지 않는 버전을 각각 전체 프로젝트를 압축해서 올려주세요. 감사합니다.

김영한 · Answer

버전문제가 아니라 엉뚱한데 소스를 넣어서 문제가 발생했다는 것이고, 지금은 잘 해결되신거지요^^?

김선동 · Answer

앗 버전문제는 맞아요! 에러가 발생했는데 스프링이 종료되지 않는 문제입니다 ㅠㅠ 정확히는 2.2.8버전에서는 위에 작성한 에러가 출력되면서 종료가 되지만, 2.3.0 버전 이후부터는 에러가 출력되지않고 종료되지도 않습니다. 문제 해결은 버전을 낮춰서 해결했습니다... 감사합니다!!
