The view is due to an issue with the enhanced code:

public void afterrunning (Joinpoint joinpoint,object returnvalue) {

Could not instantiate Bean class [org.springframework.aop.aspectj.AspectJPointcutAdvisor]: Constructor threw exception ; Nested exception is java.lang.IllegalArgumentException:error at:: 0 formal Unbound in pointcut
