안녕하세요

Question

강의를 들으면서 생긴 질문입니다. 간단한 테스트 코드를 작성해보려 하는데 다음과 같은 에러가 발생하였습니다. java.lang.IllegalStateException: Failed to load ApplicationContext at

네 이 오류는 @Autiwired 로 선언된 객체, 위에서는 UrlFilterInvocationSecurityMetadataSource 가 되겠네요 그런데 이 빈 객체를 @Autowired 할려고 하는데 UrlFilterInvocationSecurityMetadataSource 타입의 빈으로 생성된 객체가 하나도 존재하지 않는다는 의미입니다 그래서 @Bean, @Component, @Service 과 같은 어노테이션을 선언해서 해당객체가 빈으로 생성되도록 하거나 스프링에서 지원하는 빈생성 클래스인 FactoryBean 을 사용해서 빈으로 생성하는 로직을 구현해야 합니다 즉 @Autowired 된 빈을 찾고 있는데 해당 객체가 빈으로 생성되도록 선언된 구문이 없기 때문에 발생하는 오류이기 때문에 빈으로 생성하는 구문이 존재하는지 살펴 보시기 바랍니다 이 부분은 스프링시큐리티에 관련된 영역이 아니라서 자세한 설명을 드리기는 어려운 점 양해 부탁드립니다
