</tx:advice>


<aop:config>
<aop:pointcut id="allManagerMethod" expression="execution(* edu.ysu.usermgr.manager.*.*(..))"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="allManagerMethod"/>
</aop:config>

</bean>
</beans>

Answer 1

通过XML元素来查找BeanDefinitionDecorator,你的错误是找不到那个BeanDefinitionDecorator.好好看下配置文件,是不是前缀和引用出可错误.

Answer 2

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:aop="http://www.springframework.org/schema/aop"

xsi:schemaLocation="

http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
<!-- 事务处理 -->
<bean id="transactionManager"

<property name="sessionFactory" ref="sessionFactory"></property>
</bean> <!-- 事务控制 -->
<tx:advice id="txAdvice"
transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="save*" propagation="REQUIRED" />
<tx:method name="update*" propagation="REQUIRED" />
<tx:method name="remove*" propagation="REQUIRED" />
<tx:method name="get*" read-only="true" />
</tx:attributes>
</tx:advice> <aop:config>
<!-- 管理事务操作 -->
<aop:pointcut id="servicesPointcut"
expression="execution(* com.jack.user.model.*.*(..))" />
<aop:advisor advice-ref="txAdvice"
pointcut-ref="servicesPointcut" />
</aop:config>
和上面的内容比较下,看看不是不那里有缺少啦.
