不要重复设计DAO!（spring+hibernate泛型DAO)事务配置问题。

原文链接：http://www.ibm.com/developerworks/cn/java/j-genericdao.html
这里的源文件里有个类FinderIntroductionInterceptor是implements org.springframework.aop.IntroductionInterceptor接口的，如果在applicationContext.xml配置了该bean的定义：<bean id="finderIntroductionAdvisor" class="genericdao.finder.impl.FinderIntroductionAdvisor" />，用<aop-config>声明方式配置事务就会报错。如果去掉该BEAN的定义就可以或着去掉<aop-config>也可以通过。不清楚到底是什么问题，有知道的大侠麻烦解答下，谢谢！
附件里是原文（另存为的网页）+源码（j-genericdao.zip），jar包太多不能一并上传。

这是我的配置文件 就是在源码基础上修改添加了事务控制就报错了
去掉
<aop:config>

<aop:pointcut id="serviceOperation"
expression="execution(* com.kxdsoft.pms.persistence.department.IDepartmentDAO.*(..))" />
<aop:advisor pointcut-ref="serviceOperation"
advice-ref="txAdvice" />

</aop:config>
就可以了.

或者去掉：
<bean id="finderIntroductionAdvisor"
class="genericdao.finder.impl.FinderIntroductionAdvisor" />
finderIntroductionAdvisor是实现了org.springframework.aop.IntroductionInterceptor接口的
也可以 是不是它们之间有冲突？

看不懂你的配置。
我直接贴核心。

<aop:config>
     <aop:advisor 
pointcut="execution(* com.orizone.hbmobile.hbcm.services.*..*ServImpl.*(..))" 
advice-ref="transactionAdvice" order="1"/>
</aop:config>

		<tx:method name="*" read-only="true"/>
		<tx:method name="save*"/>

	</tx:attributes>
</tx:advice>
	
<bean id="transactionManager"
	class="org.springframework.orm.hibernate3.HibernateTransactionManager">
	<property name="sessionFactory">
		<ref bean="sessionFactory"/>
	</property>
</bean>


<!--genericDao-->
<bean id="genericDao"
	class="com.orizone.hbmobile.hbcm.dao.generic.impl.GenericDaoImpl">
	<property name="sessionFactory" ref="sessionFactory"/>
</bean>
	
<!--baseDao-->
<bean id="baseDao" class="com.orizone.hbmobile.hbcm.dao.impl.BaseDaoImpl"
	parent="genericDao"/>

<!-- genericServ -->
<bean id="genericServ"
	class="com.orizone.hbmobile.hbcm.services.generic.impl.GenericServImpl"
	abstract="true"/>
	
<!-- baseServ -->
<bean id="baseServ"
	class="com.orizone.hbmobile.hbcm.services.impl.BaseServImpl"
	abstract="true" parent="genericServ"/>
<!-- demoServ -->
<bean id="demoServ"
	class="com.orizone.hbmobile.hbcm.services.impl.DemoServImpl"
	parent="baseServ"/>

不知道楼主加上事务控制以后,报的是什么样的错误啊？从配置上来看,目前看不出什么问题.把异常贴上来看一下吧.

反正不加<aop-config>就通过。什么错也不会报。
留下<aop-config> 去掉
<bean id="finderIntroductionAdvisor"
class="genericdao.finder.impl.FinderIntroductionAdvisor" />
也可以通过，什么错也不会报！麻烦能帮忙看一下吗？源码都在附件里。谢谢！

晕,附件只是IBM的文章啊,很早以前看过一次.没有源码.
