Rabbitmq(三)

1.在服务器安装好rabbitmq后，自己配置自己用的vhost，exchange和queue的绑定 

2.项目添加RabbitMqClient.dll（nuget获取）引用

3.添加helper就可以使用了

        {

            using (IConnection conn = GetFactory().CreateConnection())
            {

                                      noAck: true,//和tcp协议的ack一样，为false则服务端必须在收到客户端的回执（ack）后才能删除本条消息

                        myproc(message);
                    }
                    catch (Exception)

                }





            }

        }
    }
}

　　

b.MQMessage

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace koala.application.models
{
    public class MQMessage
    {

        public string Msg { get; set; }
        public string Exchange { get; set; }
        public string RouteKey { get; set; }

    }
}

　

c.webconfig

  <add key="mqConnectStrings" value="ip;port;vhostName;Username;pwd" />
    <add key="mqExchange" value="amq.direct" />
    <add key="routKeySingle" value="im.msg.single" />

d.发送消息

发送消息
     private static string mqExchange = ConfigurationManager.AppSettings["mqExchange"];
     private static string routKeySingle = ConfigurationManager.AppSettings["routKeySingle"];
       
    string modelJson = JsonConvert.SerializeObject(model);
                MQMessage mqMsg = new MQMessage
                {
                    Exchange = mqExchange,
                    RouteKey = routKeySingle,
                    Msg = modelJson
                };
                RabbitMqHelper.PublishMsg(mqMsg);            

　　

e.消费消息

 string routKeySingle = ConfigurationManager.AppSettings["routKeySingle"]; 
Task task1 = Task.Factory.StartNew(() =>
            {
                RabbitMqHelper.ConsumeMsg(routKeySingle, (msg) => { imSingleInsertFun(msg); });
            });

注释：消费消息是创建的windows服务不停的去跑，监听队列里的消息然后消费处理
