Error creating bean with name 'org.springframework.context.annotation.internalRequiredAnnotationProc

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
