RabbitMQ是实现了高级消息队列协议(AMQP)的开源消息代理软件(亦称面向消息的中间件)。RabbitMQ服务器是用Erlang语言编写的,而集群和故障转移是构建在开放电信平台框架上的。所有主要的编程语言均有与代理接口通讯的客户端库
安装RabbitMQ必须要有Erlang的环境,没有装好环境的这里给出Erlang的官网可自行下载:https://www.erlang.org
一、配置RabbitMQ
1.将RabbitMQ的安装路径添加到环境变量中,启动RabbitMQ
2.启动WEB管理界面:rabbitmq-plugins enable rabbitmq_management
3.登录管理界面,RabbitMQ的管理界面的默认访问路径为:http://localhost:15672
4.可以使用guest用户登录,密码也是guest
二、C#实现的小案例,这里给出官方教程:https://www.rabbitmq.com/getstarted.html
1.发布者
var factory = new ConnectionFactory(); factory.HostName = "localhost"; factory.UserName = "guest"; factory.Password = "guest"; using (var connection = factory.CreateConnection()) { using (var channel = connection.CreateModel()) { bool durable = true; //声明一个名称为:hello的持久化的队列 channel.QueueDeclare("hello", durable, false, false, null); string message = GetMessage(args); var properties = channel.CreateBasicProperties(); properties.SetPersistent(true); for (int i = 0; i < 100; i++) { var body = Encoding.UTF8.GetBytes(message+i); channel.BasicPublish("", "hello", properties, body); Console.WriteLine(" Send {0}", message+i); } } } Console.ReadKey();
2.消费者
var factory = new ConnectionFactory(); factory.HostName = "localhost"; factory.UserName = "guest"; factory.Password = "guest"; using (var connection = factory.CreateConnection()) { using (var channel = connection.CreateModel()) { bool durable = true; //在MQ上定义一个持久化队列,名称为:hello,如果名称相同不会重复创建 channel.QueueDeclare("hello", durable, false, false, null); //输入1,那如果接收一个消息,如果没有应答,则客户端不会收到下一个消息 channel.BasicQos(0, 1, false); var consumer = new QueueingBasicConsumer(channel); channel.BasicConsume("hello", false, consumer); while (true) { var ea = (BasicDeliverEventArgs)consumer.Queue.Dequeue(); var body = ea.Body; var message = Encoding.UTF8.GetString(body); int dots = message.Split('.').Length - 1; Thread.Sleep(dots * 1000); Console.WriteLine("Received {0}", message); Console.WriteLine("Done"); //回复确认 channel.BasicAck(ea.DeliveryTag, false); } } }
3、通过发布者的创建我们可以在管理界面中查看到添加的队列
