SpringMVC中事务是否可以加在Controller层的问题

<!-- (事务管理)transaction manager, use JtaTransactionManager for global tx -->
<bean id="transactionManagerMS"class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSourceMS" />
</bean>
 
<!-- 可通过注解控制事务 -->
<tx:annotation-driven transaction-manager="transactionManagerMS" />
