NoSuchBeanDefinitionException: нет подходящего компонента типа 'javax.persistence.EntityManagerFactory'.

Я смотрел на предыдущие вопросы, такие как Нет подходящего бина типа [javax.persistence.EntityManager]

и я правильно аннотировал свой объект DAO (как указывалось в их решении). 

@Repository
@Transactional
public class OrderDAO{
    @PersistenceContext
    private EntityManager entityManager;

    public long insert(Order order){
        //Added into the persistence context
        entityManager.persist(order);
        return order.getId();
    }
}

диспетчер-servlet.xml: 

    <beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:context="http://www.springframework.org/schema/context"
        xmlns:mvc="http://www.springframework.org/schema/mvc"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

        <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
          <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
          <property name="url" value="jdbc:mysql://localhost:3306/orders_db"/>
          <property name="username" value="root"/>
          <property name="password" value="root123"/>

        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.hbm2ddl.auto">create</prop>
            </props>
        </property>
        </bean>

        <context:component-scan base-package="es.neil" />
        <mvc:annotation-driven />
        <mvc:resources mapping="/css/**" location="/css/" />
    </beans>

Я также пытался добавить bean entityManagerFactory в мою конфигурацию dispatcher-servlet.xml, но это не помешало отображению этого исключения.

Исключение:

Я вижу только компонент источника данных, определенный в вашей конфигурации. Не существует фабричного компонента управления объектами, который четко отражен в вашем сообщении об ошибке.

Вы можете объявить отсутствующий компонент в коде или в XML. См. Например: https://www.baeldung.com/the-persistence-layer-with-spring-and-jpa
