    @Around("execution(public void com.flyaction.demo.aopreview.PayServiceImpl.pay(..))") 
    public Object aroundNotify(ProceedingJoinPoint proceedingJoinPoint) throws Throwable { 
        Object retValue = null; 
        System.out.println("-----@Around环绕通知AAA"); 
        retValue = proceedingJoinPoint.proceed();//放行 
        System.out.println("-----@Around环绕通知BBB"); return retValue; 
    } 
}
