解决办法：

在bean.xml加

<!-- 配置事务 -->
    <bean id="txManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"/>
    </bean>
    <!-- 声明事务 -->
    <tx:advice id="txAdvice" transaction-manager="txManager">        
        <tx:attributes>          
            <tx:method name="get*" read-only="true"/>
            <tx:method name="delete*" read-only="false"/>
            <tx:method name="*"/>
        </tx:attributes>
    </tx:advice>
     <aop:config>
        <aop:pointcut id="fooServiceOperation" expression="execution(* cn.xxs.service.impl.*.*(..))"/>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="fooServiceOperation"/>
    </aop:config>
    
     <aop:aspectj-autoproxy/>

 

或者注解方式解决：

在bean.xml加

<!-- 使用注解方式使用事务 -->
    <tx:annotation-driven/>
    
    <!-- 配置事务 -->
    <bean id="txManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"/>
    </bean>

在UserServiceImpl加

ok，问题解决了，可以删除了。
