自定义注解日志耗时统计

自定义注解

@Target({
          
   ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface ServiceMonitor {
          
   
}

自定义AOP

@Aspect
@Component
public class ServiceMonitorAspect {
          
   

/**
     * 切点
     *  @annotation(com.alibaba.cloud.retail.item.normal.openapi.common.monitor.ServiceMonitor)：匹配所有的方法上拥有ServiceMonitor注解的方法外部调用
     * @within(com.alibaba.cloud.retail.item.normal.openapi.common.monitor.ServiceMonitor) ： 匹配所有类上拥有ServiceMonitor注解的方法外部调用
     */
    @Pointcut("@annotation(com.zh.aop.ServiceMonitor)" + "|| @within(com.zh.aop.ServiceMonitor)")
    public void pointCut() {
          
   
    }


/**
* 环绕通知
*/
    @Around("pointCut()")
    public Object around(ProceedingJoinPoint joinPoint) {
          
   
        try {
          
   
            StopWatch stopWatch = new StopWatch();
            stopWatch.start();
            Object proceed = joinPoint.proceed();
            stopWatch.stop();
            String className = joinPoint.getTarget().getClass().getSimpleName();
            System.out.println("ServiceMonitorAspect_simpleName:{}"+className + "#"+joinPoint.getSignature().getName()+", timeMillis:{} ms"+stopWatch.getTotalTimeMillis());
            return  proceed;
        } catch (Throwable t) {
          
   
            System.out.println("ServiceMonitorAspect_error:"+ t);
            return ResultWrapper.fail("CATEGORY-F-001-00-99-001", "系统异常,请稍后重试");
        }
    }
}

使用

@ServiceMonitor
@Service
public class DemoServiceImpl implements DemoService {
          
   
    @Override
    public void hello() {
          
   
        System.out.println("DemoServiceImpl_hello");
        hello2();
    }

    public void hello2(){
          
   
        System.out.println("DemoServiceImpl_hello2");
    }
}

注意：@within 匹配所有类上拥有ServiceMonitor注解的方法外部调用
