AspectJ获取方法注解的信息

    /**
     * Get value of annotated method parameter
     */
    private <T extends Annotation> T getMethodAnnotation(ProceedingJoinPoint joinPoint, Class<T> clazz) {
        MethodSignature methodSignature = (MethodSignature) joinPoint.getSignature();
        Method method = methodSignature.getMethod();
        return method.getAnnotation(clazz);
    }
