확인 해볼 것

1. 클래스에서 @Entity 애노테이션이 있는 지 확인

2. Configure파일에서 

 <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean" autowire="byName">

        

        <property name="dataSource" ref="dataSource"/>

        <property name="packagesToScan" value="모델 패키지가 제대로 설정 되었는지 확인~!"/>
