spring、hibernate整合配置

spring与hibernate整合配置非常灵活：
1、在applicationContext.xml中引入hibernate.cfg.xml，如下：

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="dataSource" ref="dataSource"/>

		<!-- 使用hibernate自身的配置文件配置 
		<property name="configLocations">
			<list>
				<value>classpath:cn/itcast/spring/hibernate/hibernate.cfg.xml</value>
			</list>
		</property>
</bean>

2、将hibernate相关配置配在applicationContext.xml中

	<!-- 本地会话工厂bean,spring整合hibernate的核心接口 -->
	<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="dataSource" ref="dataSource"/>
		
		<!-- 指定hibernate自身的属性 -->
		<property name="hibernateProperties">
		<props>
			<prop key="hibernate.dialect">${hibernate.dialect}</prop>
			<prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
			<prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>
		</props>
		</property>
		
		<!-- 从指定目录下查找映射文件-->
		<property name="mappingDirectoryLocations">
			<list>
				<value>cn/itcast/spring/domain</value>
			</list>
		</property> 
		
		<!-- 映射文件的位置
		<property name="mappingResources">
			<list>
				<value>cn/itcast/spring/domain/Customer.hbm.xml</value>
			</list>
		</property>
		 -->
	</bean>
