异常信息： xml 文件配置注解时报错
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.context.annotation.internalRequiredAnnotationProcessor': BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'org.springframework.aop.aspectj.AspectJPointcutAdvisor#0': Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.aop.aspectj.AspectJPointcutAdvisor]:
Constructor threw exception; nested exception is java.lang.IllegalArgumentException: warning no match for this type name: cn.itcast.service.imple.AopServiceBean3 [Xlint:invalidAbsoluteTypeName]
原因：
applicatonContext.xml
<aop:config>
<aop:aspect id="asp" ref="myInterceptor1">
<!--<aop:pointcut id="mycut" expression="execution(* cn.itcast.service.imple.AopServiceBean3..*(..))" />--> 正确的
<!--<aop:pointcut id="mycut" expression="execution(* cn.itcast.service.imple.AopServiceBean3.*.*(..))" />-->正确的
<aop:pointcut id="mycut" expression="execution(* cn.itcast.service.imple.AopServiceBean3..*.*(..))" />正确的
<!--下面的配置有问题AopServiceBean3.*(..)-->
<!--<aop:pointcut id="mycut" expression="execution(* cn.itcast.service.imple.AopServiceBean3.*(..))" />-->错误的
<aop:before method="doAccessCheck" pointcut-ref="mycut"/>
</aop:aspect>
如用注解：
@Pointcut("execution (* cn.itcast.aop.service.imple..*.*(..))") //imple包下所有类的所有方法进行拦截
//@Pointcut("execution (* cn.itcast.aop.service.imple.AopServiceBean2.*(..))")只对AopServiceBean2类下方法进行拦截
有一个问题没有搞明白：为什么注解和配置一样会报错？
annotation:::::::<!--<aop:pointcut id="mycut" expression="execution(* cn.itcast.service.imple.AopServiceBean3.*(..))" />-->错误的
xml:::::::::::::::::::://@Pointcut("execution (* cn.itcast.aop.service.imple.AopServiceBean2.*(..))")只对AopServiceBean2类下方法进行拦截 正确的
