Question

spring管理事务为什么是service层

Answer 1

<!–声明事务–>
< bean id=”txManager”>
< property name=”sessionFactory” ref=”sessionFactory” />
< /bean>
< !– 创建通知–>
< tx:advice id=”txAdvice” transaction-manager=”txManager”>
< tx:attributes>
< tx:method name=”find*” read-only=”true”/>
< tx:method name=”has*” read-only=”true”/>
< tx:method name=”add*” propagation=”REQUIRED” />
< tx:method name=”alter*” propagation=”REQUIRED” />
< tx:method name=”upd*” propagation=”REQUIRED” />
< tx:method name=”del*” propagation=”REQUIRED” />
< tx:method name=”exec*” propagation=”REQUIRED” />
< /tx:attributes>
< /tx:advice>
< !– 切入接口所在的包 –>
< aop:config>
< aop:pointcut id=”serviceOperation” expression=”execution(public * org.bgi.*.service.*.*(..))” />
< aop:advisor advice-ref=”txAdvice” pointcut-ref=”serviceOperation” />
< /aop:config>
