[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;

        }

    }

}
