@Transactional doesn't open Hibernate Transaction

I declared Spring Beans in my beans.xml:

<context:annotation-config />   
<context:component-scan base-package="com.pack"/>
<tx:annotation-driven transaction-manager="transactionManager" />
<bean id="transactionManager"
              class="org.springframework.orm.hibernate4.HibernateTransactionManager"> 
     <property name="sessionFactory" ref="sessionFactory"/>
     <property name="dataSource" ref="dataSource"></property>
</bean>

dataSource and sessionFactory beans: 

@Bean(name = "dataSource")
    public DriverManagerDataSource dataSource() {
        DriverManagerDataSource ds = new DriverManagerDataSource();
        ds.setUsername(userName);
        ds.setPassword(password);
        ds.setDriverClassName(driverName);
        ds.setUrl(url);
        return ds;
    }

@Bean(name = "sessionFactory")
    public LocalSessionFactoryBean localSessionFactoryBean() {
        LocalSessionFactoryBean factory = new LocalSessionFactoryBean();
        factory.setDataSource(dataSourceConfiguration.dataSource());

        Properties props = new Properties();
        props.put("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");
        props.put("hibernate.hbm2ddl.auto", "update");
        props.put("hibernate.current_session_context_class", "thread");
        factory.setHibernateProperties(props);
        factory.setMappingResources("com/pack/Item.hbm.xml");

        return factory;
    }

If I use sessionFactory and dataSource beans separately they work well. A also have DAO class:

@Repository(value = "itemDaoHibernateImpl")
public class ItemDaoHibernateImpl implements ItemDao {

    @Resource(name = "sessionFactory")
    private SessionFactory factory;

    public void setFactory(SessionFactory factory) {
        this.factory = factory;
    }

    public Session session() {
        return factory.getCurrentSession();
    }

    @Override
    public void create(Item item) {
        session().save(item);
    }

I don't open the sessions because I want to force Spring to do this. I have Service class with method:

@Override
@Transactional
public void create(Item item) {
    dao.create(item);
}

When I call it, I have the exception:

org.hibernate.HibernateException: save is not valid without active transaction

I've done like this tutorial tells. Where is my mistake?

Try to remove props.put("hibernate.current_session_context_class", "thread") from your sessionFactory configuration. When you are using Spring managed transactions, you don't need it. Let me know if that works.

When I have come across this before it is due to whether Spring is using CGLib or Javassist to augment your class to provide transactionality. if I remember correctly if you only have Javassist in then the class that Spring needs to create the proxy on in order to implement the Transactional annotation must implement an interface.
