PrimaryDatasourceConfig.java

@Configuration
@EnableJpaRepositories(basePackages = { "com.study.springboot" },    // Repository 경로
        entityManagerFactoryRef = "primeEntityManager", transactionManagerRef = "primeTransactionManager")
public class PrimaryDatasourceConfig {
...
}

SecondaryDatasourceConfiguration.java

@Configuration
@EnableJpaRepositories(basePackages = { "com.study.springboot" },     // Repository 경로
        entityManagerFactoryRef = "productEntityManager", transactionManagerRef = "productTransactionManager")
public class SecondaryDatasourceConfiguration {
...
}

 

문제는 @EnableJpaRepositories(basePackages = { "com.study.springboot" } 이 부분입니다.

Repository 경로가 중복되어 있어서, 각 DB 설정에 Repository 가 잘못 매칭되어 발생한 오류 입니다.

아래와 같이 변경했더니 해결되었습니다.

PrimaryDatasourceConfig.java

@Configuration
@EnableJpaRepositories(basePackages = { "com.study.springboot.system" },    // Repository 경로
        entityManagerFactoryRef = "primeEntityManager", transactionManagerRef = "primeTransactionManager")
public class PrimaryDatasourceConfig {
...
}

SecondaryDatasourceConfiguration.java

@Configuration
@EnableJpaRepositories(basePackages = { "com.study.springboot.product" },     // Repository 경로
        entityManagerFactoryRef = "productEntityManager", transactionManagerRef = "productTransactionManager")
public class SecondaryDatasourceConfiguration {
...
}
