에러문 분석

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'securityConfig' defined in file

→ ‘securityConfig’라는 이름의 빈을 생성하는데 UnsatisfiedDependencyException(의존성 주입 예외)이 발생하였다.

 

org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.slub.chamchimayo.oauth.token.AuthTokenProvider' available: expected at least 1 bean which qualifies as autowire candidate.

→ ‘AuthTokenProvider’ 라는 이름의 빈이 존재 하지 않는다.

 

문제 분석

SecurityConfig.class

SecurityConfig 클래스는 빈으로 등록된 AuthTokenProvider를 주입받고 있다.

에러 발생원인은 테스트가 실행되면 SecurityConfig 클래스가 빈으로 등록(@Configuation 어노테이션이 붙어 컴포넌트의 스캔대상이된다) 되는데, 이 때 생성자 주입을 받을 AuthTokenProvider라는 빈이 없는 것이다.
(그 외에도 CorsProperties, AppProperties, CustomUserDetailsService... 빈도 없다.)

→ 테스트가 실행될때 위의 빈들은 컴포넌트 스캔의 대상이 아니기 때문이다.

 

LoginControllerTest.java

컨트롤러가 예상대로 동작하는지에 대해 테스트하기위해 @WebMvcTest 를 사용하였다.

@WebMvcTest 어노테이션은 사용시 다음 내용만 스캔하도록 제한한다. 그래서 보다 가벼운 테스트가 가능하다.

• @Controller, @ControllerAdvice, @JsonComponent, Converter, GenericConverter, Filter, HandlerInterceptor, WebMvcConfigurer, HandlerMethodArgumentResolver

 

AuthTokenProvider.class 를 확인해보자

AuthTokenProvider클래스는 @Service 어노테이션을 통해 빈으로 등록된다. 나머지 클래스들도 마찬가지이다.

따라서 위 테스트 환경의 스캔대상이 아니기 때문에 AuthTokenProvider클래스는 빈으로 등록되지 않는 것이다.

 

해결방법

SecurityConfig 클래스가 주입받는 클래스들을 컴포넌트 스캔의 대상으로 설정해주면된다.

@ComponentScan 어노테이션을 사용해서 빈으로 등록해준다.

• @ComponentScan의 basePackages는 명시한 패키지 내의 @Component, @Service, @Controller, @Repository.. 등의 클래스들을 등록시킨다.

문제 해결!

 

 

@ComponentScan은 모든 컨트롤러 테스트에 사용되므로, 따로 클래스로 만든 후 상속하자
