spring에서 Unable to find a @SpringBootConfiguration가 발생할 때 에러.
나 같은 경우는 multi module project를 구성할 때 에러 메세지가 나왔다.
multi module에서 library module과 project module을 나눠서 구성할 때.
에러 메세지
java.lang.IllegalStateException: Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test

코드
spring에서 multi module 이슈라면 kotlin인지 java인지는 중요하지 않다.
@ExtendWith(SpringExtension::class)
@SpringBootTest
class JpaRepositoryTest {
@Autowired
lateinit var sut: MysqlJpaRepository
...
}
해결
@ExtendWith(SpringExtension::class)
@Import(TestConfig::class)
@SpringBootTest
class JpaRepositoryTest {
@SpringBootConfiguration
@ComponentScan("com.meansoup") // 여기는 base package name
class TestConfig
@Autowired
lateinit var sut: MysqlJpaRepository
...
}
원인
library가 되는 모듈에는 @SpringBootApplication이 없다.
따라서 @SpringBootConfiguration도 없는데 그렇기 때문에 bean이 있다는 것을 알지 못한다.
위와 같이 테스트에서 @SpringBootConfiguration를 명시해주므로써 bean을 인지하고 사용할 수 있다.
