    <bean id="userDAO" class="onlyfun.caterpillar.UserDAO">

        </property>

</beans>

可以看到使用Spring整合Hibernate的好处，可以直接将DataSource注入至 org.springframework.orm.hibernate3.LocalSessionFactoryBean中，至于Hibernate所 需的相关设定，则可透过LocalSessionFactoryBean的相关属性来设定，像是设定资料库名称、使用者名称、密码等， LocalSessionFactoryBean会建立SessionFactory的实例，并在执行依赖注入时将这个实例设定给UserDAO。
