인프런 커뮤니티 질문&답변

안녕하세요?

강의 잘 듣고 있습니다.

다름이 아니라 TransactionManager를 설정하는 방법의 차이에 대해서 궁금해서 질문을 올리게 되었습니다.

JpaConfig 클래스를 하나 만들고 entityManagerFactory와 sessionFactory 메소드를 만든 후

TransactionManager 를 아래와 같이 설정하였습니다.

@Bean

@Qualifier("transactionManager")

public PlatformTransactionManager hibernateTransactionManager() {

        //JpaTransactionManager txManager = new JpaTransactionManager();

        //txManager.setEntityManagerFactory(entityManagerFactory());

        //return txManager;

        HibernateTransactionManager transactionManager

                = new HibernateTransactionManager(sessionFactory().getObject());

        return transactionManager;

    }

}

그런데 HibernateTransactionManager로 만든 transactionManager는

jpa의 save가 제대로 되지 않고 JpaTransactionManager로 만든 transactionManager는

save가 정상적으로 동작하는 것을 확인하였습니다.

어떤 차이가 있길래 코드가 동작하지 않는 것일까요??

아래는 클래스의 전체 코드입니다.

(패키지 명은 ... 처리 하였습니다.)

@Configuration
@EnableTransactionManagement
public class HibernateConfig {

    @Autowired
    private DataSource dataSource;

    @Bean
    public LocalSessionFactoryBean sessionFactory() {
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();

        sessionFactory.setDataSource(dataSource);
        sessionFactory.setPackagesToScan(new String[] { "..." });
        sessionFactory.setHibernateProperties(getHibernateProperties());

        return sessionFactory;
    }

    @Primary
    @Bean
    public EntityManagerFactory entityManagerFactory() {
        HibernateJpaVendorAdapter vendorAdapter =
                new HibernateJpaVendorAdapter();

        LocalContainerEntityManagerFactoryBean factory =
                new LocalContainerEntityManagerFactoryBean();
        factory.setJpaVendorAdapter(vendorAdapter);
        factory.setPackagesToScan("...");
        factory.setDataSource(dataSource);
        factory.afterPropertiesSet();
        factory.setJpaProperties(getHibernateProperties());
        return factory.getObject();
    }


    private Properties getHibernateProperties() {
        Properties properties = new Properties();

        properties.put(AvailableSettings.HBM2DDL_AUTO, "");
        properties.put(AvailableSettings.PHYSICAL_NAMING_STRATEGY, "org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl");
        properties.put(AvailableSettings.SHOW_SQL, false);
        properties.put(AvailableSettings.HBM2DDL_DB_NAME, "mysql");
        properties.put(AvailableSettings.DIALECT, "...");
        properties.put(AvailableSettings.FORMAT_SQL, "true");
        properties.put(AvailableSettings.ENABLE_LAZY_LOAD_NO_TRANS, true);

        return properties;

    }

    @Bean
    public PlatformTransactionManager hibernateTransactionManager() {
        HibernateTransactionManager transactionManager
                = new HibernateTransactionManager(sessionFactory().getObject());

        return transactionManager;
    }
}
