<!-- 1.导入资源文件 -->
<context:property-placeholder location="classpath:db.properties" />

<!-- 2.配置 C3P0 数据源 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="user" value="${jdbc.user}"></property>
<property name="password" value="${jdbc.password}"></property>
<property name="driverClass" value="${jdbc.driverClass}"></property>
<property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>
<property name="initialPoolSize" value="${jdbc.initialPoolSize}"></property>
<property name="maxPoolSize" value="${jdbc.maxPoolSize}"></property>
</bean>

<!-- 3.配置 SessionFactory，注入数据源 -->
<bean id="sessionFactory" class="">
<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="classpath:hibernate.cfg.xml" />
<property name="mappingLocations" value="classpath:com/kou/entities/*.hbm.xml" />
</bean>

<!--第二部分： 配置 Spring 的声明式事务 -->
<!-- 1. 配置 hibernate 的事务管理器，注入sessionFactory -->
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>

<!-- 2. 配置事务增强处理，注入事务管理器 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="get*" read-only="true" />
<tx:method name="*" />
</tx:attributes>
</tx:advice>

<!-- 3. 配置事务切入点, 再把事务增强处理和事务切入点关联起来 -->
<aop:config>
<aop:pointcut expression="execution(* com.kou.service.*.*(..))"
id="txPointcut" />
<aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut" />
</aop:config>
</beans>
