hibernate 注解使用异常解决方法

Exception in thread "main" org.hibernate.MappingException: An AnnotationConfiguration instance is required to use <mapping class="bean.Email"/>
at org.hibernate.cfg.Configuration.parseMappingElement(Configuration.java:1648)

at demo.demo01.main(demo01.java:12)

解决方法：

错误：

Session session=new Configuration().configure().buildSessionFactory().openSession();

应该是使用：

Session session=new AnnotationConfiguration().configure().buildSessionFactory().openSession();

或者是：

<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
</bean>

给为：

 <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
       <property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
    </bean>
