<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <!--<property name="configLocation" value="classpath:com/sun/config/mybatis.xml"/>--><!--此种方式必须结合mybatis配置文件使用-->
    <property name="mapperLocations" value="classpath:com/sun/mapper/User.xml" /><!--使用此种方式可以不用额外配置mybatis配置文件-->
</bean>

<!--事务管理器配置-->
<bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

</bean>
<tx:advice id="txadvice" transaction-manager="txManager">
    <tx:attributes>

</tx:advice>
<!--aop切面配置-->
<aop:config>
    <aop:pointcut id="pointcut" expression="execution(* com.sun.service.impl.*.*(..))"/>
    <aop:advisor advice-ref="txadvice"  pointcut-ref="pointcut"/>
</aop:config>
<!--关联sqlsessionfactory可以跳过sqlsessiontemplate但是必须继承SqlSessionDaoSupport-->
<bean id="userDaoImpl" class="com.sun.dao.impl.UserDaoImpl">
    <property name="sqlSessionFactory" ref="sqlSessionFactory"/>
</bean>
<bean id="userServiceImpl" class="com.sun.service.impl.UserServiceImpl">
