@Aspect
@Component
class ExecutedTimeAop {
    private val logger = LoggerFactory.getLogger(ExecutedTimeAop::class.java)
    @Around("execution(* com.six.god..create(..))")
    @Throws(Throwable::class)
    fun run(joinPoint: ProceedingJoinPoint): Any? {
        var result: Any? = null
        val timeMillis = measureTimeMillis {
            result = joinPoint.proceed()
        }
        return result
    }
}

作用于com.six.god下所有名字为create()的方法

配合注解使用
