若你的项目出现如下异常：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userService' defined in class path resource [beans.xml]: BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.aop.support.DefaultBeanFactoryPointcutAdvisor#0': Cannot resolve reference to bean 'pointcut' while setting bean property 'pointcut'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'pointcut': Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: org/aspectj/weaver/reflect/ReflectionWorld$ReflectionWorldException

问题出现原因及解决方法：

没有导入aspectjweaver-1.7.1.jar的jar包，在项目中导入即可
