问题是这样, 在applicationContext.xml的配置里,
配置和测试dataSource和sessionFactory都正常,
都能拿到Connection和session,(我这里用的是DriverManagerDataSource),
直到我配置好txAdvice和txManger测试都正常,到最后加上aop:config的时候就报错了!
所以我认为问题出在下面的aop:config的配置上, 除非删掉它无论我怎么配置它都报错!
无奈大家帮我看看吧, 第一次问问问题分都给你们吧, 也没多少分其实~~
上配置:
- XML code
<context:property-placeholder location="jdbc.properties" /> <bean name="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="${jdbc.driverClassName}" /> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="configLocation" value="classpath:hibernate.cfg.xml" /> </bean> <bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> <property name="dataSource" ref="dataSource" /> </bean> <aop:config> <aop:pointcut expression="execution(* cn.tboa.dao..*.*(..))" id="daoMethod" /> <aop:advisor advice-ref="txAdvice" pointcut-ref="daoMethod" /> </aop:config> <tx:advice id="txAdvice" transaction-manager="txManager"> <tx:attributes> <tx:method name="*" propagation="REQUIRED" read-only="true" /> <tx:method name="find*" read-only="true" /> <tx:method name="get*" read-only="true" /> <tx:method name="save*" propagation="REQUIRED" /> <tx:method name="update*" propagation="REQUIRED" /> <tx:method name="delte*" propagation="REQUIRED" /> <tx:method name="merge*" propagation="REQUIRED" /> </tx:attributes> </tx:advice>最后再声明一下, 在添加aop:config之前,所有配置都没问题的!
我有这样的一个包结构:
cn.tboa.dao
cn.tboa.dao.impl
错误信息如下:
