Aspect出现error Type referred to is not an annotation type

使用Aspect记录操作日志时，启动项目报以下异常：

严重: StandardWrapper.Throwable
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mvcContentNegotiationManager': Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: error Type referred to is not an annotation type: log

实现代码：

/**
     * 前置通知，用于拦截controller层的操作
     * 
     * @param joinPoint
     * @param log
     */
    @Before("controllerAspect() && @annotation(log)")
    public void doBefore(JoinPoint joinPoint, SystemControllerLog sysLog) {
        HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes())
                .getRequest();
        String ip = request.getRemoteAddr();
        logger.info("ip:" + ip);
    }

原因是@Before里的注解和方法中的参数名不一致，改为一致后启动正常：

/**
     * 前置通知，用于拦截controller层的操作
     * 
     * @param joinPoint
     * @param log
     */
    @Before("controllerAspect() && @annotation(sysLog)")
    public void doBefore(JoinPoint joinPoint, SystemControllerLog sysLog) {
        HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes())
                .getRequest();
        String ip = request.getRemoteAddr();
        logger.info("ip:" + ip);
    }
