비고 근본 원인(root cause)의 풀 스택 트레이스를, 서버 로그들에서 확인할 수 있습니다.

위와 같은 오류가 발생했었다.

일단 오류 내용은 loginUserBean을 주입할 수 없다는 메시지이다. 주입 받은 변수에 @Lazy가 있는지 없는지 확인해보는 오류였다.

참고로, Java로 세팅한 Spring Framework는 @Lazy 어노테이션을 안 붙여도 상관없지만,

Xml로 세팅한 Spring Framework는 Bean을 주입할 때, @Lazy를 붙여야 한다.

Xml 같은 경우 서버가 가동될 때 무조건 주입하려고 시도하기 때문이다.

또한, Bean의 scope가 session일 경우 주입에 실패하고 오류를 발생시키는 것을 방지하기 위해 @Lazy를 작성해준다.

여하튼 나의 오류는 import를 같은 이름의 또 다른 @Lazy를 import해서 그랬었다.

import org.hibernate.validator.internal.util.stereotypes.Lazy;

위의 것이 아니라, 아래가 Spring Framework 프로젝트에서의 우리가 일반적으로 알고 있는 @Lazy이다.

import org.springframework.context.annotation.Lazy;
