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

<?xml version="1.0" encoding="UTF-8"?>
<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:c="http://www.springframework.org/schema/c"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:p="http://www.springframework.org/schema/p"
	xmlns:util="http://www.springframework.org/schema/util"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
		http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd
		http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.2.xsd">
	
	<aop:config>
		<aop:aspect ref="logger">		
			<aop:pointcut id="dbmethod" expression="execution(* com.cet.peccore.DbInterfaceForPG.SetupTableForPG.*(..))" />	
			<aop:before pointcut-ref="dbmethod" method="LogBefore" />			
			<aop:after pointcut-ref="dbmethod" method="LogAfter" />
		</aop:aspect>
	</aop:config>
	
	<bean id="dbInterface" class="com.cet.peccore.DbInterface.DbInterface" autowire="byType"/>
	<bean id="setupTable" class="com.cet.peccore.DbInterfaceForPG.SetupTableForPG"/>
	<bean id="logger" class="com.cet.peccore.PecTrend.util.MyLogger"/>	
</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

1. <dependency>
2. <groupId> org.aspectj</groupId >
3. <artifactId> aspectjweaver</artifactId >
4. <version> 1.8.7</version >
5. </dependency>
