No qualifying bean of type 'javax.persistence.EntityManagerFactory' available - entitymanager

Question

No qualifying bean of type 'javax.persistence.EntityManagerFactory' available - tried everything.
The part of the spring-db.xml:
<context:component-scan base-package="com.z.university.**"/>
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
p:dataSource-ref="dataSource"
p:packagesToScan="com.z.university.**.model">
...
The class with injected EntityManager
#Repository
#Transactional
public class JpaNotepadRepositoryImpl extends JpaAbstractGenericDao<Notepad>
implements GenericDao<Notepad> {
#PersistenceContext
private EntityManager entityManager;
Erros log:
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jpaNotepadRepositoryImpl': Injection of persistence dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'javax.persistence.EntityManagerFactory' available
