DbaSqlService中
@Service
@Transactional(readOnly=true)
public class DbaSqlService extends CommonAction{

applicationContext.xml中
<context:annotation-config /> 
<context:component-scan base-package="com.netease" />
<tx:annotation-driven transaction-manager="checkdbasqlTransactionManager"/>
    <bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"/>
<bean id="checkdbasqlTransactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="MarketingDataSource" />
</bean>

如果我把<tx:annotation-driven transaction-manager="checkdbasqlTransactionManager"/> 去掉就不会有以上问题，但是无法做事务操作了。请问这个是为什么呢？
