Spring AOP 必导jar包

使用spring Aop编程除了要加入Spring的spring-aop jar包，还要加入aspectjrt.jar，aspectjweaver.jar，以及aopalliance_1.0.jar，否则报错：

org.springframework.beans.factory.BeanCreationExcspring-aopeption: Error creating bean with name 'org.springframework.aop.config.internalAutoProxyCreator': Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.aop.aspectj.annotation.AnnotationAwareAspectJAutoProxyCreator]: Constructor threw exception; nested exception is Java.lang.NoClassDefFoundError: org/aopalliance/intercept/MethodInterceptor
