浅析RabbitMQ死信队列

在现代分布式系统中，消息队列扮演着至关重要的角色。它们可以实现应用程序之间的异步通信，并确保数据的可靠传输和处理。而在这个领域中，RabbitMQ作为一种强大而受欢迎的消息队列解决方案，具备了高效、可靠和灵活的特性。然而，即使使用了RabbitMQ，我们仍然会遇到一些不可预料的情况，例如消费者无法处...

RocketMQ5.1.3，死信队列重复投递问题。

RocketMQ5.1.3，消费者故意抛出异常，进行消息消费重试，消费者设置最大重试次数为3，并且创建另一个消费者用于消费死信队列。运行代码发现死信队列消费者消费了三次消息，并没有耗尽所有重试次数才把消息放入死信队列。生产者代码：消费者代码：死信队列消费者代码：消费者执行情况：死信队列消费...

SpringBoot整合RabbitMQ实现死信队列

前面一文通过Java整合RabbitMQ实现生产消费（7种通讯方式），本文基于SpringBoot实现RabbitMQ中的死信队列和延迟队列。概念介绍什么是死信死信可以理解成没有被正常消费的消息，在RabbitMQ中以下几种情况会被认定为死信：消费者使用basic.reject或basic....

RabbitMQ 发布确认交换机死信队列延迟队列（下）

Topic交换机在上面这张图中,我们可以看到X绑定了两个队列,绑定类型是direct。队列Q1绑定键为orange,队列Q2绑定键有两个:一个绑定键为black，另一个绑定键为green.在这种绑定情况下，生产者发布消息到exchange上，绑定键为orange的消息会被发布到队列Q1。绑定键为 b...

RabbitMQ 发布确认交换机死信队列延迟队列（上）

发布确认1.设置要求队列必须持久化2.设置要求队列中的消息3.发布确认什么是发布确认？只有当消息完完整整的发送完成发布确认之后，消息才算在磁盘上保存好了，数据再怎么服务器开关都不会丢失开启发布确认的方法发布确认默认是没有开启的，如果要开启需要调用方法 confirmSelect，每当你要想使用发布确...

RabbitMQ 的死信队列、延迟队列

死信队列：死信队列是专门存放那些死信消息的，也就是我们配置死信队列可以将那些将会被丢弃的死信消息放入队列中。死信消息：1. 消息被消费方否认确认的，消费者使用 channel.basicNack 或 channel.basicReject 返回给队列的，并且此时 requeue（重新发送）属性被设置...

死信是什么，如何运用RabbitMQ的死信机制？

前言我们在上次讨论RabbitMQ的消息可靠性时，已经提到了死信队列（详见系列文章《RabbitMQ 能保证消息可靠性吗》），死信概念是RabbitMQ的重要特性，官网也有该特性的介绍，那么这种设计有什么用，我们又该怎么使用死信呢？一起开始本次的学习吧一、死信与AMQP死信是指由于某些...
