Spring + Hibernate4 integration, and transaction are managed by Spring AOP, example :
spring-hibernate.xml
<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"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">
<bean id="txManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
<tx:advice id="txAdvice" transaction-manager="txManager">
<tx:attributes>
<tx:method name="get*" read-only="true" />
<tx:method name="*" />
</tx:attributes>
</tx:advice>
<aop:config>
<aop:pointcut id="userDaoPointCut"
expression="execution(* com.mkyong.users.service.*Dao.*(..))" />
<aop:advisor advice-ref="txAdvice" pointcut-ref="userDaoPointCut" />
</aop:config>
</beans>
The system shows ClassNotFoundException: org.aspect.weaver....

Solution
To solve it, declares spring-aspects, it will get the org.aspectj library automatically.
pom.xml

<spring.version>3.2.8.RELEASE</spring.version>

Hi,
When I added the spring-orm dependency in Eclipse Kepler. I got the following error:
ArtifactDescriptorException: Failed to read artifact descriptor for org.springframework:spring-orm:jar
However my code worked by adding the spring-aspects dependency. So thanks for that!
But any idea why I got the error for the orm dependency?
Thanks
Thank you very much!!
Thank you very much.
