[MQ]ActiveMQ消息收发简单例子

例子中使用的消息类型是：MapMessage。代码比较简单，帖出来给大家看看：

接收消息：

private void Receive()
        {
            var factory = new ConnectionFactory(Program.BrokerUri);
            var timeout = new TimeSpan(0, 0, 10);
            using (var connection = factory.CreateConnection())
            {
                using (var session = connection.CreateSession())
                {
                    var destination = SessionUtil.GetDestination(session, Program.NormalQueueDestination);
                    using (var consumer = session.CreateConsumer(destination))
                    {
                        connection.Start();
                        var stopwatch = new Stopwatch();
                        var index = 1;
                        for (var i = 0; i < Program.MessageCount; i++)
                        {
                            if (index == 1)
                            {
                                stopwatch.Start();
                            }

                            try
                            {
                                var message = (IMapMessage)consumer.Receive(timeout);
                                index++;
                                var messageObj = Common.GetMessageObjByIMapMessage(message);
                                if (messageObj != null)
                                {
                                    //Debug.WriteLine(messageObj.MediaTaskId);
                                }

                                if (index == Program.StatisticsMessageCountSpan)
                                {
                                    stopwatch.Stop();
                                    var spendSeconds = stopwatch.Elapsed.TotalSeconds;
                                    var speed = Program.StatisticsMessageCountSpan / spendSeconds;
                                    Debug.WriteLine("Receive " + Program.StatisticsMessageCountSpan + " Messages Spend:" + spendSeconds + " Seconds. (" + speed.ToString("0.00") + "/s)");

                                    stopwatch.Reset();
                                    index = 1;
                                }
                            }
                            catch (Exception ex)
                            {
                                Debug.WriteLine(ex);
                            }
                        }
                    }
                }
            }
        }

 发送消息：

private void Send()
        {
            var factory = new ConnectionFactory(Program.BrokerUri);
            using (var connection = factory.CreateConnection())
            {
                using (var session = connection.CreateSession())
                {
                    var destination = SessionUtil.GetDestination(session, Program.NormalQueueDestination);
                    using (var producer = session.CreateProducer(destination))
                    {
                        connection.Start();
                        var mediaTaskId = 100000000000000;
                        var stopwatch = new Stopwatch();
                        var index = 1;
                        for (var i = 1; i <= Program.MessageCount; i++)
                        {
                            if (index == 1)
                            {
                                stopwatch.Start();
                            }

                            try
                            {
                                mediaTaskId++;
                                var message = session.CreateMapMessage();
                                Common.SetMapMessage(message, Common.GetMessageObj(mediaTaskId.ToString()));
                                producer.Send(message);
                                index++;
                                
                                if (index == Program.StatisticsMessageCountSpan)
                                {
                                    stopwatch.Stop();
                                    var spendSeconds = stopwatch.Elapsed.TotalSeconds;
                                    var speed = Program.StatisticsMessageCountSpan / spendSeconds;
                                    Debug.WriteLine("Send " + Program.StatisticsMessageCountSpan + " Messages Spend:" + spendSeconds + " Seconds. (" + speed.ToString("0.00") + "/s)");

                                    stopwatch.Reset();
                                    index = 1;
                                }
                            }
                            catch (Exception ex)
                            {
                                Debug.WriteLine(ex);
                            }
                        }
                    }
                }
            }

            MessageBox.Show(@"Send Done!");
        }

简单监听封装类：

using System;
using System.Diagnostics;
using System.Threading;
using Apache.NMS;

namespace ActiveMQ.PerformanceTest
{
    public class ActiveMqListener
    {
        public event MessageReceivedEventHandler MessageReceived;
        private readonly IMessageConsumer _messageConsumer;
        private readonly TimeSpan _timeout;
        private readonly int _sleepMinutes;
        private bool _listen;

        public ActiveMqListener(IMessageConsumer messageConsumer, TimeSpan timeout, int sleepMinutes)
        {
            _messageConsumer = messageConsumer;
            _timeout = timeout;
            _sleepMinutes = sleepMinutes;
        }

        public void Start()
        {
            _listen = true;

            StartListening();
        }

        public void Stop()
        {
            _listen = false;
        }

        private void StartListening()
        {
            while (_listen)
            {
                var message = _messageConsumer.Receive(_timeout);
                if (message == null)
                {
                    Debug.WriteLine("[%Notice:ActiveMqListener Start " + _sleepMinutes + " Minutes Sleep.%]");
                    Thread.Sleep(_sleepMinutes * 1000 * 60);
                }
                else
                {
                    FireRecieveEvent(message);
                }
            }
        }

        private void FireRecieveEvent(object message)
        {
            if (MessageReceived != null)
            {
                MessageReceived(this, new MessageEventArgs(message));
            }
        }
    }

    public delegate void MessageReceivedEventHandler(object sender, MessageEventArgs args);

    public class MessageEventArgs : EventArgs
    {
        private readonly object _message;

        public object Message
        {
            get { return _message; }
        }

        public MessageEventArgs(object message)
        {
            _message = message;
        }
    }
}
