ClassNotFoundException: org.aspectj.weaver.reflect.ReflectionWorld$ReflectionWorldException
By:Roy.LiuLast updated:2019-08-17
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.
