spring boot AspectJ方式实现AOP 拦截器

@Aspect
@Slf4j
@Component
public class ServiceFilter {

    @Pointcut("execution(* com.demo.Service.*(..))")
    public void pointcutService() {}


    
    @Around("pointcutService()")
    public Object calCost(ProceedingJoinPoint joinPoint) throws Throwable {
        long startTime = System.currentTimeMillis();
        Object result = joinPoint.proceed();
        long cost = System.currentTimeMillis() - startTime;
        log.info("Service." + joinPoint.getSignature().getName() + " method cost: " + cost + "ms.");
        return result;
    }

    
    @Before("pointcutService()")
    public static void before(JoinPoint point){
        log.info("Before of Service." + point.getSignature().getName() );
    }
