本文详细介绍了使用ActiveMQ进行消息发送（producer）与消息接收（consumer）的基本步骤及代码实现，包括创建连接工厂、连接、会话、生产者与消费者等关键组件，以及如何发送与接收消息。

李石磊学习心得（若有不当之处还请见谅）

在实际的项目开发中，往往需要及时的数据服务传输，因为高效稳定的数据传输成为了硬性的需求，本人在参考别人建议后做出Active MQ，现将学习的内容简要做下记录，以便日后自己和他人参考。

消息发送（producer）

using System;
using System.Collections.Generic;
using System.Text;
using Apache.NMS;
using Apache.NMS.ActiveMQ;
using System.IO;
using System.Xml.Serialization;
using System.Runtime.Serialization.Formatters.Binary;

namespace Publish
{
class Program
{
static void Main(string[] args)
{
try
{
//Create the Connection Factory
IConnectionFactory factory = new ConnectionFactory("tcp://localhost:61616/");
using (IConnection connection = factory.CreateConnection())
{
//Create the Session
using (ISession session = connection.CreateSession())
{
//Create the Producer for the topic/queue
IMessageProducer prod = session.CreateProducer(
new Apache.NMS.ActiveMQ.Commands.ActiveMQTopic("testing"));

//Send Messages
int i = 0;

while (!Console.KeyAvailable)
{
ITextMessage msg = prod.CreateTextMessage();
msg.Text = i.ToString();
Console.WriteLine("Sending: " + i.ToString());
prod.Send(msg, Apache.NMS.MsgDeliveryMode.NonPersistent, Apache.NMS.MsgPriority.Normal, TimeSpan.MinValue);

System.Threading.Thread.Sleep(5000);
i++;
}
}
}

Console.ReadLine();
}
catch (System.Exception e)
{
Console.WriteLine("{0}",e.Message);
Console.ReadLine();
}
}
}
}

消息接收（consumer）

using System;
using System.Collections.Generic;
using System.Text;
using Apache.NMS;
using Apache.NMS.ActiveMQ;
using System.IO;
using System.Xml.Serialization;
using System.Runtime.Serialization.Formatters.Binary;

namespace Subscribe
{
class Program
{
static void Main(string[] args)
{
try
{
//Create the Connection factory
IConnectionFactory factory = new ConnectionFactory("tcp://localhost:61616/");

//Create the connection
using (IConnection connection = factory.CreateConnection())
{
connection.ClientId = "testing listener";
connection.Start();

//Create the Session
using (ISession session = connection.CreateSession())
{
//Create the Consumer
IMessageConsumer consumer = session.CreateDurableConsumer(new Apache.NMS.ActiveMQ.Commands.ActiveMQTopic("testing"), "testing listener", null, false);

consumer.Listener += new MessageListener(consumer_Listener);

Console.ReadLine();
}
connection.Stop();
connection.Close();
}
}
catch (System.Exception e)
{
Console.WriteLine(e.Message);
}
}

static void consumer_Listener(IMessage message)
{
try
{
ITextMessage msg = (ITextMessage)message;
Console.WriteLine("Receive: " + msg.Text);
}
catch (System.Exception e)
{
Console.WriteLine(e.Message);
}
}
}
}
