[JPA] Not a managed type: class 에러

jpa 설정을 하고 테스트 코드를 돌려보니 해당 에러가 났다.

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userRepository' defined in com.sgw.common.repository.UserRepository defined in @EnableJpaRepositories declared on DataSourceConfiguration: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type: class com.sgw.common.domain.User

어노테이션 문제일까 싶어 여기저기 확인해보다

@Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
        factory.setJpaVendorAdapter(jpaVendorAdapter());
        factory.setPackagesToScan("com.swg.common.domain");    // <- 해당 부분에 오타가 났었다.ㅠ
        factory.setDataSource(dataSource());
        return factory;
    }

오타를 조심하자.ㅠ

factory.setPackagesToScan 해당 부분에 오타가 나서 @Entity 설정해준 클래스를 읽지 못하는 것이였다.
수정해주니 바로 동작되었다.ㅜ

 

추가적으로 LocalContainerEntityManagerFactoryBean 설정을 사용안한다면 @EntityScan으로 entity 클래스를 지정해주니 해당 어노테이션 설정을 확인해주면 될거같다.
