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 [email protected]: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 QUEUE
using 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 QUEUE
using System;
using System.Threading;
using Apache.NMS;
using Apache.NMS.ActiveMQ;
using Apache.NMS.ActiveMQ.Commands;
//消费者2
namespace 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
