[Spring Batch] DB 연결 Config 클래스 작성

config 패키지 안에 MetaDBConfig, DataDBConfig 클래스 생성

 

1. MetaDBConfig.java

@Configuration
public class MetaDBConfig {

//    충돌 방지
    @Primary
    @Bean
    @ConfigurationProperties(prefix = "spring.datasource-meta")
    public DataSource metaDBSource() {

        return DataSourceBuilder.create().build();
    }

    @Primary
    @Bean
    public PlatformTransactionManager metaTranscationManager(){

        return new DataSourceTransactionManager(metaDBSource());
    }
}

 

2. DataDBConfig

@Configuration
@EnableJpaRepositories(
        basePackages = "com.jongwon.repository",
        entityManagerFactoryRef = "dataEntityManager",
        transactionManagerRef = "dataTransactionManager"
)
public class DataDBConfig {

    @Bean
    @ConfigurationProperties(prefix = "spring.datasource-data")
    public DataSource dataDBSource(){
        return DataSourceBuilder.create().build();
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean dataEntityManager(){

        LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();

        em.setDataSource(dataDBSource());
        em.setPackagesToScan(new String[]{"com.jongwon.entity"});
        em.setJpaVendorAdapter(new HibernateJpaVendorAdapter());

        HashMap<String, Object> properties = new HashMap<>();
        // properties를 강제적으로 설정 할 수 있다.
        properties.put("hibernate.hbm2ddl.auto", "update");
        properties.put("hibernate.show_sql", "true");
        em.setJpaPropertyMap(properties);

        return em;
    }

    @Bean
    public PlatformTransactionManager dataTransactionManager(){
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(dataEntityManager().getObject());
        return transactionManager;
    }
}
