使用順序：
1 <tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true" />
之后才是xml配置：
2 <tx:advice id="txAdviceService" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="add*" read-only="false"/>
<tx:method name="add*" read-only="false"/>
<tx:method name="update*" read-only="false"/>
<tx:method name="del*" read-only="false"/>
<tx:method name="apply*" read-only="false"/>
<tx:method name="*" read-only="true"/>
</tx:attributes>
</tx:advice>
<aop:config>
<aop:pointcut id="serviceMethods"
expression="execution(* com.joe.service.*.*(..))"/>
<aop:advisor advice-ref="txAdviceService" pointcut-ref="serviceMethods"/>
</aop:config>
<bean id="transactionManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
如果寫反會出現如果使用的
@Transactional的方法在 <tx:method name="*" read-only="true"/>
里面 就會發現沒有可寫事務 ：
error:Write operations are not allowed in read-only mode (FlushMode.NEVER/MANUAL): Turn your Session into FlushMode.COMMIT/AUTO or remove 'readOnly' marker from transaction definition.
