NoSuchBeanDefinitionException：没有可用的“javax.persistence.EntityManagerFactory”类型的合格 bean
[英]NoSuchBeanDefinitionException: No qualifying bean of type 'javax.persistence.EntityManagerFactory' available
问题描述
I've had a look at previous questions like No qualifying bean of type [javax.persistence.EntityManager]
我看过以前的问题，如Noqualified bean of type [javax.persistence.EntityManager]
and I have annotated my DAO object correctly (as their solution has pointed out).并且我已经正确地注释了我的 DAO 对象（正如他们的解决方案所指出的那样）。
@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();
}
}
dispatcher-servlet.xml:调度程序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>
I have also tried adding the bean entityManagerFactory to my dispatcher-servlet.xml configuration, but that didn't stop that exception from showing.我还尝试将 bean entityManagerFactory 添加到我的 dispatcher-servlet.xml 配置中，但这并没有阻止该异常的显示。
Exception:例外：

I can see only data source bean defined in your configuration.我只能看到您的配置中定义的数据源 bean。 There is no entity manager factory bean, which is clearly reflected in your error message.没有实体管理器工厂bean，这在您的错误消息中清楚地反映出来。
You can declare the missing bean in code or in XML.您可以在代码或 XML 中声明缺少的 bean。 See for example: https://www.baeldung.com/the-persistence-layer-with-spring-and-jpa参见例如： https : //www.baeldung.com/the-persistence-layer-with-spring-and-jpa
