hibernate.cfg.xml这个文件有没有？数据库和对象的映射关系文件。

我把它放到spring里托管了。。下面是spring的代码:

<?xml version="1.0" encoding="UTF-8"?>

		<property name="password" value="accp"></property>

	</bean>

	<bean id="sessionFactory"

		<property name="hibernateProperties">

				<prop key="hibernate.dialect">

					org.hibernate.dialect.Oracle9Dialect

				</prop>

			</props>

		</property>

	</bean>

	

	<bean id="studentDao" class="com.accp.dao.impl.StudentDaoImpl">

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

	</bean>

	

	<bean id="studentService" class="com.accp.service.impl.StudentServiceImpl">

		<property name="dao" ref="studentDao"/>

	</bean>

	

	<bean id="studentLoginAction" class="com.accp.action.student.LoginAction">

		<property name="service" ref="studentService"></property>

	</bean>

</beans>
