延时队列

处理超时订单

• Orderqueueconsumer.Php

• Orderqueueproducer.Php

Orderqueueproducer.php

payload = $data;
    }
    public function getExchangeBuilder() : ExchangeBuilder
    {
        return parent::getExchangeBuilder(); // TODO: Change the autogenerated stub
    }
}

Orderqueueconsumer.php

Demo
$builder = new AmqpBuilder();
        $builder->setDelayedQueue('order_exchange', 1, 'delay_exchange', 'delay_route');
        $que = ApplicationContext::getContainer()->get(DelayProducer::class);
        var_dump($que->produce(new OrderQueueProducer(['order_sn' => (string)mt_rand(10000, 90000)]), $builder))
