一、什麼是RabbitMQ。詳見 http://www.rabbitmq.com/。html
做用就是提升系統的併發性,將一些不須要及時響應客戶端且佔用較多資源的操做,放入隊列,再由另一個線程,去異步處理這些隊列,可極大的提升系統的併發能力。web
二、安裝json
RabbitMQ服務:http://www.rabbitmq.com/download.html。
(安裝完RabbitMQ服務後,會在Windows服務中看到。若是沒有Erlang運行環境,在安裝過程當中會提醒先安裝Erlang環境。http://www.erlang.org/downloads)安全
.net客戶端類庫:http://www.rabbitmq.com/dotnet.html併發
下載Erlang環境並安裝異步
地址:http://www.erlang.org/downloadstcp
而後安裝RabbitMQ,安裝成功後會在服務中看到該服務。函數
三、插件工具
RabbitMQ提供了不少好用的插件,最經常使用的就是web管理工具,啓動此插件。oop
CMD中運行命令:rabbitmq-plugins enable rabbitmq_management
注:rabbitmq-plugins 所在路徑爲:D:\Program Files\RabbitMQ Server\rabbitmq_server-3.4.0\sbin
web管理工具的地址是:http://localhost:15672,初始用戶名:guest 初始密碼:guest
四、配置
配置文件地址爲:C:\Documents and Settings\Administrator\Application Data\RabbitMQ\rabbitmq.config,默認沒有rabbit.config文件,須要手工新建(默認會有rabbitmq.config.example 做爲參考)。基於安全,作了兩個配置,以下:
[ {rabbit, [ {loopback_users, [<<"guest">>]}, {tcp_listeners, [{"127.0.0.1", 1234}, {"10.121.1.48", 8009}]} ]} ].
loopback_users:設置只能在與RabbitMq服務同一臺機器上訪問服務的用戶。
tcp_listeners:設置RabbitMQ監聽的IP地址與端口。只監聽局域網內網iP、修改默認端口,防止被入侵攻擊。
設置完後,別忘記了如下操做,不然配置不起做用。
- 中止RabbitMQ服務;
- 從新安裝服務使配置生效:rabbitmq-service.bat install
此命令要切換到路徑:D:\Program Files\RabbitMQ Server\rabbitmq_server-3.4.0\sbin
- 啓動RabbitMQ服務;
五、Demo練習。
消息生產者: class Program { static void Main(string[] args) { try { ConnectionFactory factory = new ConnectionFactory(); factory.HostName = Constants.MqHost; factory.Port = Constants.MqPort; factory.UserName = Constants.MqUserName; factory.Password = Constants.MqPwd; using (IConnection conn = factory.CreateConnection()) { using (IModel channel = conn.CreateModel()) { //在MQ上定義一個持久化隊列,若是名稱相同不會重複建立 channel.QueueDeclare("MyFirstQueue", true, false, false, null); while (true) { string customStr = Console.ReadLine(); RequestMsg requestMsg = new RequestMsg(); requestMsg.Name = string.Format("Name_{0}", customStr); requestMsg.Code = string.Format("Code_{0}", customStr); string jsonStr = JsonConvert.SerializeObject(requestMsg); byte[] bytes = Encoding.UTF8.GetBytes(jsonStr); //設置消息持久化 IBasicProperties properties = channel.CreateBasicProperties(); properties.DeliveryMode = 2; channel.BasicPublish("", "MyFirstQueue", properties, bytes); //channel.BasicPublish("", "MyFirstQueue", null, bytes); Console.WriteLine("消息已發送:" + requestMsg.ToString()); } } } } catch (Exception e1) { Console.WriteLine(e1.ToString()); } Console.ReadLine(); } }
class Program { static void Main(string[] args) { try { ConnectionFactory factory = new ConnectionFactory(); factory.HostName = Constants.MqHost; factory.Port = Constants.MqPort; factory.UserName = Constants.MqUserName; factory.Password = Constants.MqPwd; using (IConnection conn = factory.CreateConnection()) { using (IModel channel = conn.CreateModel()) { //在MQ上定義一個持久化隊列,若是名稱相同不會重複建立 channel.QueueDeclare("MyFirstQueue", true, false, false, null); //輸入1,那若是接收一個消息,可是沒有應答,則客戶端不會收到下一個消息 channel.BasicQos(0, 1, false); Console.WriteLine("Listening..."); //在隊列上定義一個消費者 QueueingBasicConsumer consumer = new QueueingBasicConsumer(channel); //消費隊列,並設置應答模式爲程序主動應答 channel.BasicConsume("MyFirstQueue", false, consumer); while (true) { //阻塞函數,獲取隊列中的消息 BasicDeliverEventArgs ea = (BasicDeliverEventArgs)consumer.Queue.Dequeue(); byte[] bytes = ea.Body; string str = Encoding.UTF8.GetString(bytes); RequestMsg msg = JsonConvert.DeserializeObject<RequestMsg>(str); Console.WriteLine("HandleMsg:" + msg.ToString()); //回覆確認 channel.BasicAck(ea.DeliveryTag, false); } } } } catch (Exception e1) { Console.WriteLine(e1.ToString()); } Console.ReadLine(); } }
