使用ActiveMQ发送和接受消息（1）

第一步：搭建ActiveMQ环境

a.安装jdk与tomcat，设置环境变量%JAVVA_HOME% = C:\Program Files\Java\jdk1.7.0_11

b.解压下载得到的apache-activemq-5.7.0-bin.zip，输出路径：E:\ActiveMQ\apache-activemq-5.7.0

    下载地址：http://activemq.apache.org/download-archives.html

c.修改E:\ActiveMQ\apache-activemq-5.7.0\conf\activemq.xml

    Line129: <storeUsage limit="10 gb"/>
    Line132: <tempUsage limit="1 gb"/>

    若磁盘空间不够，在安装过程中会得到WARN信息。

d.双击运行apache-activemq-5.7.0\bin\activemq.bat，一切顺利得信息“INFO | Started SelectChannelConnector@0.0.0.0:8161”

    打开http://localhost:8161/，效果如下：

第二步：使用C#实现本地和ActiveMQ之间发送/接受消息

a.下载Apache.NMS.ActiveMQ.dll和Apache.NMS.dll

    下载地址：http://activemq.apache.org/nms/download.html

    Apache.NMS.ActiveMQ-1.5.6-bin\build\net-2.0\release\Apache.NMS.ActiveMQ.dll
    Apache.NMS-1.5.1-bin\net-2.0\release\Apache.NMS.dll

b.新建C#项目，添加引用Apache.NMS.ActiveMQ.dll和Apache.NMS.dll

c.编写生产者类，实现向服务器发送消息

//#define TOPIC //使用topic模式#define QUEUE  // 使用queue模式using System;using System.Threading;using Apache.NMS;using Apache.NMS.ActiveMQ;using Apache.NMS.ActiveMQ.Commands;//生产者namespace Producer{    class Program    {        static void Main(string[] args)        {            try            {                IConnectionFactory pConnFactory = new ConnectionFactory("tcp://localhost:61616");                using (IConnection pConn = pConnFactory.CreateConnection())                {                    using (ISession pSession = pConn.CreateSession())                    {#if TOPIC                        IDestination pDestination = new ActiveMQTopic("myTopicName");#endif#if QUEUE                        IDestination pDestination = new ActiveMQQueue("myQueryName"); #endif                        IMessageProducer pProducer = pSession.CreateProducer(pDestination);                        int i = 0;                        while (!Console.KeyAvailable)                        {                            ITextMessage msg = pProducer.CreateTextMessage();                            msg.Text = i.ToString();                            msg.Properties.SetInt("ITEM_TYPE", i);  // 为消息添加属性                            Console.WriteLine(string.Format("Sending: {0}", i));                            pProducer.Send(msg, MsgDeliveryMode.NonPersistent, MsgPriority.Normal, TimeSpan.MinValue);                            Thread.Sleep(2000);                            i++;                        }                    }                }                Console.ReadLine();            }            catch (Exception ex)            {                Console.WriteLine(ex.Message);                Console.Read();            }        }    }}

d.编写消费者类，实现从服务器接受消息

//#define TOPIC#define QUEUEusing System;using System.Threading;using Apache.NMS;using Apache.NMS.ActiveMQ;using Apache.NMS.ActiveMQ.Commands;//消费者namespace Consumer{    class Program    {        static void Main(string[] args)        {            try            {                IConnectionFactory pFactory = new ConnectionFactory("tcp://localhost:61616/");                using (IConnection conn = pFactory.CreateConnection())                {                    conn.ClientId = "myListenser";                    conn.Start();                    using (ISession pSession = conn.CreateSession())                    {#if TOPIC                        ITopic pTopic = new ActiveMQTopic("myTopicName");                        IMessageConsumer pConsumer = pSession.CreateDurableConsumer(pTopic, "myListenser", null, false);#endif#if QUEUE                        IDestination pDestination = new ActiveMQQueue("myQueryName");                        //IMessageConsumer pConsumer = pSession.CreateConsumer(pDestination, "ITEM_TYPE%3=0");                        IMessageConsumer pConsumer = pSession.CreateConsumer(pDestination);#endif                        pConsumer.Listener += new MessageListener(consumer_Listener);                                                Console.ReadLine();                    }                    conn.Stop();                    conn.Close();                }            }            catch (Exception ex)            {                Console.WriteLine(ex.Message);                Console.ReadKey();            }        }        static void consumer_Listener(IMessage message)        {            try            {                ITextMessage msg = message as ITextMessage;                Thread.Sleep(3000);                Console.WriteLine(string.Format("Receive 3s ago: {0}", msg.Text));            }            catch (Exception ex)            {                Console.WriteLine(ex.Message);                Console.ReadKey();            }        }    }}

//#define TOPIC#define QUEUEusing System;using System.Threading;using Apache.NMS;using Apache.NMS.ActiveMQ;using Apache.NMS.ActiveMQ.Commands;//消费者2namespace Consumer2{    class Program    {        static void Main(string[] args)        {            try            {                IConnectionFactory pFactory = new ConnectionFactory("tcp://localhost:61616/");                using (IConnection conn = pFactory.CreateConnection())                {                    conn.ClientId = "myListenser2";                    conn.Start();                    using (ISession pSession = conn.CreateSession())                    {#if TOPIC                        ITopic pTopic = new ActiveMQTopic("myTopicName");                        IMessageConsumer pConsumer = pSession.CreateDurableConsumer(pTopic, "myListenser2", null, false);#endif#if QUEUE                        IDestination pDestination = new ActiveMQQueue("myQueryName");                        IMessageConsumer pConsumer = pSession.CreateConsumer(pDestination);#endif                        pConsumer.Listener += new MessageListener(consumer_Listener);                        Console.ReadLine();                    }                    conn.Stop();                    conn.Close();                }            }            catch (Exception ex)            {                Console.WriteLine(ex.Message);                Console.ReadKey();            }        }        static void consumer_Listener(IMessage message)        {            try            {                ITextMessage msg = message as ITextMessage;                Console.WriteLine(string.Format("Receive: {0}", msg.Text));                Thread.Sleep(3000);            }            catch (Exception ex)            {                Console.WriteLine(ex.Message);                Console.ReadKey();            }        }    }}

e.效果如下
