为什么使用RabbitMq而不是ActiveMq或者RocketMq实现消息队列

由 [亡魂溺海] 提交于 2020-01-04 03:05:10
为什么使用RabbitMq而不是ActiveMq或者RocketMq？ 首先，从业务上来讲，我并不要求消息的100%接受率，并且，我需要结合php开发，RabbitMq相较RocketMq，延迟较低(微妙级)。至于ActiveMq，貌似问题较多。RabbitMq对各种语言的支持较好，所以选择RabbitMq。 先安装PHP对应的RabbitMQ,这里用的是 php_amqp 不同的扩展实现方式会有细微的差异. php扩展地址 : http://pecl.php.net/package/amqp 具体以官网为准 http://www.rabbitmq.com/getstarted.html 介绍 config.php 配置信息 BaseMQ.php MQ基类 ProductMQ.php 生产者类 ConsumerMQ.php 消费者类 Consumer2MQ.php 消费者2(可有多个) config.php <?php return [ //配置 'host' => [ 'host' => '127.0.0.1', 'port' => '5672', 'login' => 'guest', 'password' => 'guest', 'vhost'=>'/', ], //交换机 'exchange'=>'word', //路由 'routes' => [], ]; BaseMQ

how can I purge a MassTransit queue?

由 一笑奈何 提交于 2020-01-03 17:34:44
问题 I'd like to delete all the messages from a queue in my integration test SetUp routine, how can I accomplish that? No luck with googling/intellisense-bruteforce. If it matters -- I'm using RabbitMq as transport. 回答1: There's no way to "delete" from queues within MassTransit. For tests you can use temporary, random queue URIs via rabbitmq://localhost/*?temporary=true . Or you can just append ?temporary=true to the end of your existing queue URIs to have MT clean stuff up afterward. Note:

Spring RabbitTemplate - How to create queues automatically upon send

由 孤街醉人 提交于 2020-01-03 10:54:40
问题 I am using RabbitMQ together with Spring's RabbitTemplate. When sending messages to queues using the template send methods, I want the queue to automatically be created/declared if it is not already exists. It is very important since according to our business logic queue names are generated on run-time and I cannot declare them in advance. Previously we have used JmsTemplate and any call to send or receive automatically created the queue. 回答1: Yes, you can use a RabbitAdmin and admin
