<!-- 数据源配置 -->

<!-- ###########Spring与Hibernate整合  start########### -->

<!-- 方式（1）直接加载hibernate.cfg.xml文件的方式整合
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
</bean>    -->

<!-- 方式（2）连接池交给spring管理  【一部分配置写到hibernate中，一份分在spring中完成】
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
<property name="dataSource" ref="dataSource"></property>
</bean> -->

<!-- 【推荐】方式（3）所有的配置全部都在Spring配置文件中完成 -->
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<!-- 注入连接池对象 -->
<property name="dataSource" ref="dataSource"></property>

<!-- hibernate常用配置 -->
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>

<!-- 事务配置 -->
<!-- a. 配置事务管理器类 -->
<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
<!-- b. 配置事务增强(拦截到方法后如果管理事务?) -->
<tx:advice id="txAdvice" transaction-manager="txManager">
<tx:attributes>
<tx:method name="*" read-only="false"/>
</tx:attributes>
</tx:advice>
<!-- c. Aop配置 -->
<aop:config>
<aop:pointcut expression="execution(* cn.itcast.service.*.*(..))" id="pt"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="pt"/>
</aop:config>
