ORM using Hibernate's annotations with Spring

I'm trying integrate spring with hibernate but catch exception on project start.

Caused by: org.hibernate.MappingException: An AnnotationConfiguration instance is required to use <mapping class="com.domain.Worker"/

My config: from spring

<bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="org.hsqldb.jdbcDriver"/>
        <property name="url" value="jdbc:mysql://localhost/school"/>
        <property name="username" value="root"/>
        <property name="password" value="toor"/>
    </bean>

    <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource" ref="myDataSource"/>
        <property name="configLocation" value="/WEB-INF/hib.cfg.xml"/>
        <property name="hibernateProperties">

If you want to use Hibernate API with annotated entities, you need to use AnnotationSessionFactoryBean instead of LocalSessionFactoryBean.

If you want to use JPA annotations then you should likely be using a LocalEntityManagerFactoryBean rather than a LocalSessionFactoryBean.

The former loads your annotations and entities through the regular JPA methods, while your configuration quoted above attempts to use the Hibernate SessionFactory directly.
