之后执行pc.client.PullMessage获取result;对于result.Status为primitive.PullFound执行pc.processPullResult、pq.putMessage提交到processQueue;pc.submitToConsume(request.pq, request.mq)对于p.consumeOrderly执行的是p.consumeMessageOrderly,否则执行的是p.consumeMessageCurrently,他们都会执行pc.consumeInner...
Start方法执行pc.client.RegisterConsumer及pc.defaultConsumer.start(),然后异步执行pc.pullMessage(&pr);对于非consumeOrderly则通过time.NewTicker创建lockTicker,执行pc.lockAll();之后执行pc.client.UpdateTopicRouteInfo()、pc.client.CheckClientInBroker()、pc.client.SendHeartbeatToAllBrokerWithLock()及pc.client...
PropCtxType] = string(primitive.FailedReturn) } return e }) return container.ConsumeResult, err } } consumeInner方法会触发f.(*PushConsumerCallback) 小结 pushConsumer是对pull模式的封装,拉到消息之后若consumeOrderly则执行consumeMessageOrderly,否则执行的是consumeMessageCurrently,他们内部调用了consumeInner,...

推模式:Broker收到消息后,主动推送到消费者上。实现形式是:消费端注册一个监听器MessageListenerConcurrently,监听着broker上的消息,如果broker上有新消息,则触发监听器MessageListenerConcurrently。broker会自动往监听器中的ConsumeMessage()方法中推送消息 consumer.registerMessageListener(new MessageListenerConcurrently() {...
}returnConsumeOrderlyStatus.SUCCESS; } }); consumer.start(); System.out.println("开始处理消息"); } } 模式五:延时消息 消息发送到 Rocketmq 服务器后, 延迟一定时间再向消费者进行投递。 延时消息的使用场景: 比如电商里,提交了一个订单就可以发送一个延时消息,1h后去检查这个订单的状态,如果还是未付款就...
