Spring系列： 使用aop报错：nested exception is java.lang.NoClassDefFoundError: org/aspectj/weaver/reflect/ReflectionWorld$Refle

写了个最简单的aop例子

配置文件如下

 </aop:aspect>
     
     
     
     
 </aop:config>

</beans>
    
    
    
    

但是运行的时候总是报如下错误：

WARNING: Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.aop.aspectj.AspectJPointcutAdvisor#0': Cannot create inner bean '(inner bean)#29daf3' of type [org.springframework.aop.aspectj.AspectJMethodBeforeAdvice] while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#29daf3': Cannot resolve reference to bean 'dbmethod' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dbmethod': Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: org/aspectj/weaver/reflect/ReflectionWorld$ReflectionWorldException

原因：是由于classpath下缺少了aspectjweaver.jar的缘故。

解决办法：在pom.xml中加入依赖信息

<dependency>
       <groupId> org.aspectj</groupId >
       <artifactId> aspectjweaver</artifactId >
       <version> 1.8.7</version >
</dependency>
