<!-- 第一步：配置数据源 -->
<context:property-placeholder location="classpath:jdbc.properties"/>
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="jdbcUrl" value="${jdbc.url}"></property>
<property name="driverClass" value="${jdbc.driver}"></property>
<property name="user" value="${jdbc.username}"></property>

<!-- 第二步：创建sqlSessionFactory。生产sqlSession -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<!--加载mapper文件-->
<property name="mapperLocations" value="classpath:mybatis/**/*.xml"/>
<!--加载mybatis全局配置文件-->
<property name="configLocation" value="classpath:sqlMapConfig.xml"></property>
</bean>
<!-- 配置mybatis接口代理开发
* 接口类名和映射文件必须同名
*　接口类和映射文件必须在同一个目录　下
* 映射文件namespace名字必须是接口的全类路径名
*　接口的方法名必须和映射Statement的ｉｄ一致
-->
<!--批量扫描dao中的mapper-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.qunar.dao"></property>
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
</bean>

<!-- 第三步：事务 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>

<!-- 配置通知 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">

</tx:advice>

<!-- 配置拦截service -->
