[Springframework-developer] Hibernate Dao implementation (idea)

[snpe <sn...@sn...>]

Hello,
	I'm sorry if spring have this features 
I try declarative DAO implementation for hibernate.
I create hibernate mapping file and permanent class (example yu.co.snpe.hibernate.AdmSnpeUsers.java )
standard appplication-hibernate.xml with bean declaration like :
...
<bean id="usersDao" class="org.springframework.orm.hibernate.support.BaseHibernateDao">
		<property name="sessionFactory"><ref local="sessionFactory"/>
		</property>
		<property name="clazz">
			<value>yu.co.snpe.hibernate.AdmSnpeUsers</value>
		</property>
</bean>
...

and its is all - I have Dao implementation complete declarative

BaseHibernateDao.java is like (this class implemented all HibernateOperations without entity dependencies;
I make interface IBaseHibernateDao like interface HibernateOperations without entity dependences) :
