I am trying to use spring-boot and hibernate. It works well when I use repositories, but I'm trying to get a Hibernate session to create a DAO, and this DAO is not part of the transaction.
This is the test code:
Application.java
@Configuration
@ComponentScan
@EnableAutoConfiguration
@EnableTransactionManagement
public class Application implements CommandLineRunner {
@Autowired
private UserBusiness userBusiness;
@Autowired
@Bean(name="sessionFactory")
public SessionFactory sessionFactory(HibernateEntityManagerFactory factory) {
return factory.getSessionFactory();
}
@Override
public void run(String... arg0) throws Exception {
try {
userBusiness.createAdminUsers();
} catch (Exception e) {
e.printStackTrace();
}
System.out.println(userBusiness.listAll());
}
public static void main(String[] args) {
SpringApplication.run(Application.class, args).close();
}
}
UserBusinessImpl.java:
@Service
public class UserBusinessImpl implements UserBusiness {
@Autowired
private UserRepository userRepository;
@Autowired
private UserDao userDao;
@Transactional(rollbackFor=Exception.class)
public void createAdminUsers() throws Exception {
userRepository.save(new User("User1", "u1", "123"));
userRepository.save(new User("User2", "u2", "123"));
userDao.test();
throw new Exception("Rollback");
}
public List<User> listAll() {
return userRepository.findAll();
}
}
UserRepository.java
public interface UserRepository extends JpaRepository<User, Long> {
}
UserDao:
@Repository
public class UserDao {
@Autowired
private SessionFactory sessionFactory;
public void teste() {
sessionFactory.openSession().save(new User("testDao", "dao", "123"));
}
}
When I try to getCurrentSession (), it causes an error. and openSession () is separated from my transaction, so when the Throws and the Tao exception are not rolled back. The other two inserts lean back.
What will be the correct way to get currentSession in a DAO?
UPDATE: If I execute sessionFactory.openSession (), it does not give any exceptions, but is not part of the transaction.
If I try to use sessionFactory.getCurrentSession (), then stacktrace:
org.hibernate.HibernateException: No CurrentSessionContext configured!
