没有符合条件的bean＃javax.persistence.EntityManagerFactory＆＃39;可得到

Question

没有符合条件的bean＆＃39; javax.persistence.EntityManagerFactory＆＃39;可用 - 尝试了一切。

spring-db.xml的一部分：

<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">
                         ...

注入EntityManager的类

@Repository
@Transactional
public class JpaNotepadRepositoryImpl extends JpaAbstractGenericDao<Notepad> 
implements GenericDao<Notepad> {

@PersistenceContext
private EntityManager entityManager;

Erros日志：
