<!-- Mybatis与Spring集成配置： -->
    <!-- 1.配置数据源(连接池) -->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
        destroy-method="close">　　<!--　关闭连接对象销毁方法（数据库访问完毕后再将连接放回连接池，而不是关闭连接）　-->

    <!-- 2.配置sqlSession工厂(MyBatils文档) -->

        <property name="dataSource" ref="dataSource" /> </bean> -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"

<!-- Spring中事务的配置： -->
    <!-- 1.配置事务管理器 -->

        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />

            <tx:method name="get*" read-only="true"/>    <!-- 将查询事物设置为只读 -->
            <tx:method name="*" propagation="REQUIRED"/>    <!-- propagation="REQUIRED"为默认，可不写 -->
        </tx:attributes>
    </tx:advice>

    <!-- 3.配置事物切面 （即事务规则应用的“地方”）-->
    <aop:config>
        <aop:pointcut id="servicePointCut"
            expression="execution(* com.frank.services.*Service.*(..))" />
