RabbitMQ初识及简单实践

这篇文章比较全面详细的介绍了RabbitMQ中涉及的相关概念及组件，推荐阅读 超详细的RabbitMQ入门，看这篇就够了！-阿里云开发者社区 (aliyun.com).

文章是java实现的，因为工作使用的是C#, 所以使用C#进行实践。

1. 生产者：

//1、创建连接工厂
var factory = new ConnectionFactory()
 {
    HostName = "localhost",
    Port = 5672,
    Password = "guest",
    UserName = "guest",
    VirtualHost = "/"
};
using (var connection = factory.CreateConnection())
{
    var channel = connection.CreateModel();
    // 2、定义队列
    channel.QueueDeclare(queue: "test",
                    durable: false,
                    exclusive: false,
                    autoDelete: false,
                    arguments: null);

    string message = "Hello World!";
    var body = Encoding.UTF8.GetBytes(message);

    // 3、发送消息
    var properties = channel.CreateBasicProperties();
    properties.Persistent = true; // 设置消息持久化
    channel.BasicPublish(exchange: "",
    routingKey: "test",
    basicProperties: properties,
    body: body);
}
_logger.LogInformation("成功发送消息");

2. 消费者：

    // 1、创建连接
    var factory = new ConnectionFactory()
    {
        HostName = "localhost",
        Port = 5672,
        Password = "guest",
        UserName = "guest",
        VirtualHost = "/"
     };
     var connection = factory.CreateConnection();
     var channel = connection.CreateModel();
     channel.QueueDeclare(queue: "test", durable: false, exclusive: false, autoDelete: false, arguments: null);
     var consumer = new EventingBasicConsumer(channel);
     consumer.Received += (model, ea) =>
                {
                    Console.WriteLine($"model:{model}");
                    var body = ea.Body;
                    //业务逻辑
                    var message = Encoding.UTF8.GetString(body.ToArray());
                    Console.WriteLine(message);
                };
      channel.BasicConsume(queue: "test",
                                     autoAck: true,
                                     consumer: consumer);

实践为 最简单的单生产者，单消费者模式。
