<!-- 配置那些類的方法進行事務管理 --> 
<aop:config> 
<aop:pointcut id="allServiceMethod" expression="execution (* com.cms.sys.service.*.*(..))" />
<aop:advisor advice-ref="txAdvice" pointcut-ref="allServiceMethod" /> 
</aop:config> 

還有一個 
execution (* com.cms.art.service.*.*(..))" 

要怎麼寫？

可以這樣寫：將execution分開寫。 
<aop:config> 
<aop:pointcut id="allServiceMethod" expression="(execution (* com.cms.sys.service.*.*(..)))or (execution (* com.cms.art.service.*.*(..)))" />
<aop:advisor advice-ref="txAdvice" pointcut-ref="allServiceMethod" /> 
</aop:config> 

例如：

<!-- Hibernate 事務控制配置 -->
<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
<property name="nestedTransactionAllowed" value="true" />
</bean>
<!-- 使用Hibernate的事務控制器管理事務 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="save*" rollback-for="Exception" propagation="REQUIRED" />
<tx:method name="update*" rollback-for="Exception" propagation="REQUIRED" />
<tx:method name="del*" rollback-for="Exception" propagation="REQUIRED" />
<tx:method name="remove*" rollback-for="Exception" propagation="REQUIRED" />
<tx:method name="add*" rollback-for="Exception" propagation="REQUIRED" />
<tx:method name="insert*" rollback-for="Exception" propagation="REQUIRED" />
<tx:method name="auth*" rollback-for="Exception" propagation="REQUIRED" />
<tx:method name="*" rollback-for="Exception" propagation="REQUIRED" />
</tx:attributes>
</tx:advice>
<!-- 使用對實體類的事務控制 -->
<aop:config proxy-target-class="true">
<aop:advisor pointcut="execution(* com.rf..*.*Service.*(..))" advice-ref="txAdvice" />
<aop:advisor pointcut="execution(* com..*.*Service.*(..))" advice-ref="txAdvice" />
</aop:config>
