配置SessionFactory的两种方式

第一种方式，一步一步艰难的配置  

<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="dataSource" ref="dataSource"></property>
		<property name="mappingResources">
			<list>
				<value>cn/itcast/spring/hiberante/transaction/domain/Person.hbm.xml</value>
			</list>
		</property>
		<property name="hibernateProperties">
			<value>
				hibernate.dialect=org.hibernate.dialect.MySQLDialect
      		       </value>
		</property>
	</bean>
	
	<bean id="dataSource" destroy-method="close"
		class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName" value="${jdbc.driverClassName}" />
		<property name="url" value="${jdbc.url}" />
		<property name="username" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
	</bean>

第二种方式，导入hibernate的配置文件

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="configLocation">
			<value>classpath:cn/itcast/spring/hibernate/transaction/config/hibernate.cfg.xml</value>
		</property>
	</bean>
	<bean id="personDao"
		class="cn.itcast.spring.hibernate.transaction.dao.impl.PersonDaoImpl">
		<property name="sessionFactory">
			<ref bean="sessionFactory"/>
		</property>
	</bean>
	<bean
		class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="locations">
			<value>classpath:jdbc.properties</value>
		</property>
	</bean>
