Hibernate5 SessionImpl无法识别JpaTransactionManager启动的事务

我最近将旧版Java Web应用程序迁移到了Spring-boot Hibernate。球衣已在旧版应用中使用，因此继续使用spring-boot-starter-jersey。所以堆栈是：

RestfulService（Jersey）-> Spring Service-> Hibernate DAO（旧版代码）。

Spring服务和Hibernate DAO都通过各自的公共接口使用，并且在实现类的公共方法上具有@Transactional。

休眠DAO看起来像：

@存储库公共类UserDaoImpl实现UserDao {

@Autowired
@Qualifier("entityManagerFactory")
EntityManagerFactory entityManagerFactory;

public SessionFactory getSessionFactory() {
    return entityManagerFactory.unwrap(SessionFactory.class);
}

@Override
public User getUserByUserName(String userName) throws Exception {

    User user = null;
    Criteria criteria = getSessionFactory().getCurrentSession().createCriteria(User.class);
    criteria.add(Restrictions.eq("userName", userName));
    user = (User) criteria.uniqueResult();
    return user;
}

}

使用 JpaTransactionManager 时出现异常：

javax.persistence.TransactionRequiredException: no transaction is in progress.

切换到 HibernateTransactionManager ，Hibernate能够识别正在进行的事务。没有异常。

@Configuration
@EnableJpaRepositories("com.app.repository")
public class AppConfiguration {

   @Bean
   public HibernateTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) {
       SessionFactory sf = entityManagerFactory.unwrap(SessionFactory.class);
      return new HibernateTransactionManager(sf);
   }

但是它有缺点。对于较新的功能，我正在使用spring数据存储库。使用HibernateTransactionManager，JpaRepository的save方法不适用于实体。它不会触发更新sql（控制台上没有错误）。 findXX方法工作正常。

@Repository
public interface LessonCategoryRepository extends JpaRepository<LessonCategory, Long> {

   public List<LessonCategory> findByCategoryAndLanguage(@Param("category") String category, @Param("language") String language);
}

当我切换到JpaTransactionManager时，通过JpaRepository进行的更新工作正常，但开始获取javax.persistence.TransactionRequiredException：使用遗留DAO类的服务调用未进行任何事务。

总结：

使用HibernateTransactionManager：Hibernate5可以识别当前事务，但JpaRepository不会持久存储数据。
使用JpaTransactionManager：Hibernate5会话无法识别当前事务，但JpaRepository正在保留数据。

我可以使JpaTransactionManager与现有的休眠DAO类一起使用吗？要么我可以使HibernateTransactionManager与JpaRepository一起使用吗？ ..这样我就可以按原样使用旧版DAO类，但可以继续使用JpaRepositories。
