第一种:基于xml文件配置:

<!--目标对象  内部的方法就是切点-->
    <bean id="accountService" class="com.ag.service.impl.AccountServiceImpl">
        <property name="accountDao" ref="accountDao"/>
    </bean>

    <!--配置平台事务管理器-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <!--通知  事务的增强-->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <!--设置事务的属性信息的-->
        <tx:attributes>
            <tx:method name="transfer" isolation="REPEATABLE_READ" propagation="REQUIRED" read-only="false"/>
            <tx:method name="save" isolation="REPEATABLE_READ" propagation="REQUIRED" read-only="false"/>
            <tx:method name="findAll" isolation="REPEATABLE_READ" propagation="REQUIRED" read-only="true"/>
            <tx:method name="update*" isolation="REPEATABLE_READ" propagation="REQUIRED" read-only="true"/>
            <tx:method name="*"/>
        </tx:attributes>
    </tx:advice>

    <!--配置事务的aop织入-->
    <aop:config>
        <aop:pointcut id="txPointcut" expression="execution(* com.ag.service.impl.*.*(..))"/>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut"/>
    </aop:config>

第二种:注解配置:

 @Transactional(isolation = Isolation.READ_COMMITTED,propagation = Propagation.REQUIRED)

 然后在xml中配置注解驱动:

 <!--注解驱动-->
    <tx:annotation-driven transaction-manager="transactionManager"/>

测试结果:

相关依赖:

    <!--依赖-->
