使用Hibernate SessionFactory和JPA EntityManager（一起）

@Repository
public class NationalityDAO {

    @Autowired
    private SessionFactory sessionFactory;

    public List<Nationality> findAll() {
        return CastService.castList(Nationality.class,
                                    sessionFactory.getCurrentSession()
                                    .createCriteria(Nationality.class)
                                    .setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY).list());
    }
}

@Bean
public HibernateTransactionManager transactionManager() {
    HibernateTransactionManager transactionManager = new HibernateTransactionManager();
    transactionManager.setSessionFactory(sessionFactory().getObject());
    return transactionManager;
}

@Bean
public PlatformTransactionManager transactionManager(@Qualifier("entityManagerFactory") LocalContainerEntityManagerFactoryBean entityManagerFactory) {
    JpaTransactionManager transactionManager = new JpaTransactionManager();
    transactionManager.setEntityManagerFactory(entityManagerFactory.getObject());
    return transactionManager;
}

=============编辑：

下面是我的新配置：

@Configuration
@ComponentScan(basePackages = "com.my.package")
@EnableTransactionManagement
public class ApplicationConf {  
    @Bean public BCryptPasswordEncoder bCryptPasswordEncoder() {
        return new BCryptPasswordEncoder(12);
    }
}

实体：

@Entity
@Table(name = "NATIONALITY")
public class Nationality {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "nationality_id")
    private int id;
    
    @Column(name = "name")
    private String name;

    public int getId() {
        return id;
    }

    public void setId(int nationalityId) {
        this.id = nationalityId;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }   
}

@Service
@Transactional
public class NationalityService {

    @Autowired
    private NationalityDAO nationalityDAO;

    @Transactional
    public List<Nationality> findAll() {
        return nationalityDAO.findAll();
    }
}

@Repository
public class NationalityDAO {

    @PersistenceContext
    private EntityManager entityManager;

    private SessionFactory sessionFactory;

    public NationalityDAO() { }

    public NationalityDAO(SessionFactory session) {
        sessionFactory = session;
        if (!session.getCurrentSession().getTransaction().isActive()) {
            session.getCurrentSession().beginTransaction();
        }
    }

    public Session getSession() {
        if (sessionFactory != null) {
            return this.sessionFactory.getCurrentSession();
        } else {
            return this.entityManager.unwrap(Session.class);
        }
    }

    public List<Nationality> findAll() {
        return CastService.castList(Nationality.class,
                                    this.getSession()
                                    .createCriteria(Nationality.class)
                                    .setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY).list());
    }

我不知道这是否是目前最好的解决方案，但我已经简化了每个DAO的构造函数，以便它们将会话作为参数：

@Repository
public class NationalityDAO {
    private Session session;

    public NationalityDAO(Session session) {
        this.session = session;
    }

    public List<Nationality> findAll() {
        return CastService.castList(Nationality.class,
            this.session
            .createCriteria(Nationality.class)
            .setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY).list());
    }
}

然后，通过JPA检索当前会话的相应服务中发生了神奇的事情：

@Service
@Transactional
public class NationalityService {
    private NationalityDAO nationalityDAO;

    @Autowired
    public NationalityService(EntityManager entityManager) {
        if (entityManager.unwrap(Session.class) == null) {
            throw new NullPointerException();
        }

        this.nationalityDAO = new NationalityDAO(entityManager.unwrap(Session.class));
    }
}

现在它起作用了。
