　　我们需要在beans.xml配置文件下导入tx标签，aop标签

<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns="http://www.springframework.org/schema/beans"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/tx
        https://www.springframework.org/schema/tx/spring-tx.xsd
        http://www.springframework.org/schema/aop
        https://www.springframework.org/schema/aop/spring-aop.xsd">

    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

    </bean>
    <tx:advice id="txadvice" transaction-manager="transactionManager">
        <!--        给哪些方法配事务-->
        <tx:attributes>
            <tx:method name="*" propagation="REQUIRED"/>
        </tx:attributes>

    <aop:config>
        <aop:pointcut id="txPointcut" expression="execution(* com.zhang.Mapper.*.*(..))"/>
        <aop:advisor advice-ref="txadvice" pointcut-ref="txPointcut"/>
