Springframework와 Hibernate

기본설정

@Configuration
@EnableTransactionManagement
@PropertySource({ "classpath:persistence-mysql.properties" })
@ComponentScan({ "org.baeldung.spring.persistence" })
public class PersistenceConfig {
 
   @Autowired
   private Environment env;
 
   @Bean
   public LocalSessionFactoryBean sessionFactory() {
      LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
      sessionFactory.setDataSource(restDataSource());
      sessionFactory.setPackagesToScan(new String[] { "org.baeldung.spring.persistence.model" });
      sessionFactory.setHibernateProperties(hibernateProperties());
 
      return sessionFactory;
   }
 
   @Bean
   public DataSource restDataSource() {
      BasicDataSource dataSource = new BasicDataSource();
      dataSource.setDriverClassName(env.getProperty("jdbc.driverClassName"));
      dataSource.setUrl(env.getProperty("jdbc.url"));
      dataSource.setUsername(env.getProperty("jdbc.user"));
      dataSource.setPassword(env.getProperty("jdbc.pass"));
 
      return dataSource;
   }
 
   @Bean
   @Autowired
   public HibernateTransactionManager transactionManager(SessionFactory sessionFactory) {
      HibernateTransactionManager txManager = new HibernateTransactionManager();
      txManager.setSessionFactory(sessionFactory);
 
      return txManager;
   }
 
   @Bean
   public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {
      return new PersistenceExceptionTranslationPostProcessor();
   }
 
   Properties hibernateProperties() {
      return new Properties() {
         {
            setProperty("hibernate.hbm2ddl.auto", env.getProperty("hibernate.hbm2ddl.auto"));
            setProperty("hibernate.dialect", env.getProperty("hibernate.dialect"));
            setProperty("hibernate.globally_quoted_identifiers", "true");
         }
      };
   }
}

Session 주입 및 사용

SessionFactory가 여러개라면 이름 주입 방식을 사용하는 것이 좋겠다. 

public abstract class BarHibernateDAO{
 
   @Autowired
   SessionFactory sessionFactory;
 
   ...
 
   protected Session getCurrentSession(){
      return sessionFactory.getCurrentSession();
   }
}
