Spring Boot 응용 프로그램을 실행하려고합니다. 처음에는 Application Java에 패키지를 scanBasePackages로 표시하지 않았습니다. 그래서 내 응용 프로그램을 실행하지만 난 그런 문제가 있습니다 Issue With Spring: There was an unexpected error (type=Not Found, status=404) 내가 Application 클래스에서 scanBasePackages를 추가 할 때 내가 얻을 : Autowired가 작동하지 않습니다. 오류 'type of bean'이 필요합니다. '
필드 userService이 fr.umlv.orthopro.controller.UserController 에서 유형의 콩을 요구
' fr.umlv.orthopro.service.UserService '해당 찾을 수 없습니다.작업 :
이 구성 유형 'fr.umlv.orthopro.service.UserService'의 빈을 정의하는 것이 좋습니다.
그래서 답변을 찾았습니다. 패키지의 배열로 보입니다. 하지만 내가 전에 말했듯이 succes없이 scanBasePackages 주석을 추가하고 수동으로 패키지를 재구성하려고 할 때도 수동으로 작동하지 않습니다. 그래서 많은 시간이 지나면 문제가 어디서 왔는지 파악할 수 없습니다.
