Программисты! Я не понимаю, как работает атрибут propagation в аннотации @Transactional. Пожалуйста помоги)
<tx:annotation-driven transaction-manager="transactionManager"/>
<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="packagesToScan" value="com.springapp.mvc"></property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.jdbc.batch_size">10</prop>
<prop key="hibernate.max_fetch_depth">3</prop>
<prop key="jdbc.fetch_size">50</prop>
<prop key="hbm2ddl.auto">create-drop</prop>
</props>
</property>
<property name = "dataSource" ref = "dataSource"></property>
</bean>
Класс обслуживания:
@Service
public class BookManager implements IBookManager {
@Autowired
private SessionFactory sessionFactory;
@Override
@Transactional(propagation = Propagation.REQUIRES_NEW)
public void method1() {
Session session = sessionFactory.getCurrentSession();
Book book = (Book) session.load(Book.class, 1);
System.out.println("first: " + book.getTitle());
method2();
}
@Override
@Transactional(propagation = Propagation.NEVER)
public void method2() {
System.out.println("hello");
}
}
Я ожидаю, что метод method2() вызовет исключение, так как он помечен Propagation.NEVER. Но этого не происходит.

Почему это не работает?
