C#实现ActiveMQ消息队列

参考网址：https://www.cnblogs.com/swjian/p/11160129.html

一、首先需要导入两个包，分别是：Apache.NMS 和 Apache.NMS.ActiveMQ

二、创建Winform程序实现生产者功能。

三、Producer后台代码如下：

using Apache.NMS;
using Apache.NMS.ActiveMQ;
using System;
using System.Runtime.Serialization;
using System.Windows.Forms;

namespace ActiveMQProducer
{
    public partial class Producer : Form
    {
        // 生产者
        public Producer()
        {
            InitializeComponent();
            InitProducer();
        }
        private IConnectionFactory factory;

        public void InitProducer()
        {
            try
            {
                //初始化工厂，这里默认的URL是不需要修改的
                factory = new ConnectionFactory("tcp://localhost:61616");
            }
            catch
            {
                lbMessage.Text = "初始化失败!!";
            }
        }

        private void btnConfirm_Click(object sender, EventArgs e)
        {
            //通过工厂建立连接
            using (IConnection connection = factory.CreateConnection())
            {
                //通过连接创建Session会话
                using (ISession session = connection.CreateSession())
                {
                    //通过会话创建生产者，方法里面new出来的是MQ中的Queue
                    IMessageProducer prod = session.CreateProducer(new Apache.NMS.ActiveMQ.Commands.ActiveMQQueue("ActiveMQTest"));

                    #region 发送结构信息

                    //Student studentModel = new Student();
                    //studentModel.Grade = "三年级"; 
                    //studentModel.Name = "张三";
                    //studentModel.Sex = "男";
                    //studentModel.Age = "23";

                    //string temp = JsonConvert.SerializeObject(studentModel); 
                    //ITextMessage message = prod.CreateTextMessage(temp);  

                    #endregion

                    #region 发送文本信息

                    //创建一个发送的消息对象
                    ITextMessage message = prod.CreateTextMessage();
                    //给这个对象赋实际的消息
                    message.Text = txtMessage.Text;

                    #endregion 

                    //设置消息对象的属性，这个很重要哦，是Queue的过滤条件，也是P2P消息的唯一指定属性
                    message.Properties.SetString("filter", "SwipeCard");
                    //生产者把消息发送出去，几个枚举参数MsgDeliveryMode是否长链，MsgPriority消息优先级别，发送最小单位，当然还有其他重载
                    prod.Send(message, MsgDeliveryMode.NonPersistent, MsgPriority.Normal, TimeSpan.MinValue);
                    lbMessage.Text = "发送成功!!";
                    txtMessage.Text = "";
                    txtMessage.Focus();
                }
            }
        }
    }

    [DataContract]
    public class Student
    {
        [DataMember]
        public string Grade { get; set; }

        [DataMember]
        public string Name { get; set; }

        [DataMember]
        public string Sex { get; set; }

        [DataMember]
        public string Age { get; set; } 
    }
}

四、接下来创建Winform程序实现消费者功能。

五、Customer后台代码如下：

using Apache.NMS;
using Apache.NMS.ActiveMQ;
using Apache.NMS.ActiveMQ.Commands;
using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Runtime.Serialization;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace ActiveMQCustomer
{
    public partial class Customer : Form
    {
        // 消费者
        public Customer()
        {
            InitializeComponent();
            InitConsumer();
        }

        public void InitConsumer()
        {
            //创建连接工厂
            IConnectionFactory factory = new ConnectionFactory("tcp://localhost:61616");
            //通过工厂构建连接
            IConnection connection = factory.CreateConnection();
            //这个是连接的客户端名称标识
            connection.ClientId = "SwipeCardActionListener";
            //启动连接，监听的话要主动启动连接
            connection.Start();
            //通过连接创建一个会话
            ISession session = connection.CreateSession();
            //通过会话创建一个消费者，这里就是Queue这种会话类型的监听参数设置
            IMessageConsumer consumer = session.CreateConsumer(new Apache.NMS.ActiveMQ.Commands.ActiveMQQueue("ActiveMQTest"), "filter='SwipeCard'");
            //注册监听事件
            consumer.Listener += new MessageListener(consumer_Listener);
            //  connection.Stop();
            //  connection.Close();
        }

        void consumer_Listener(IMessage message)
        {
            #region 接收结构类型

            //try
            //{
            //    ActiveMQTextMessage receiveMsg = message as ActiveMQTextMessage;

            //    Student studentModel = JsonConvert.DeserializeObject<Student>(receiveMsg.Text);

            //    tbReceiveMessage.Invoke(new DelegateRevMessage(RevMessage), receiveMsg);
            //}
            //catch (Exception ex)
            //{

            //}

            #endregion

            #region 接收文本类型

            ITextMessage msg = (ITextMessage)message;
            tbReceiveMessage.Invoke(new DelegateRevMessage(RevMessage), msg);

            #endregion
        }

        public delegate void DelegateRevMessage(ITextMessage message);

        public void RevMessage(ITextMessage message)
        {
            tbReceiveMessage.Text += string.Format(@"接收到:{0}{1}", message.Text, Environment.NewLine);
        }
    }

    [DataContract]
    public class Student
    {
        [DataMember]
        public string Grade { get; set; }

        [DataMember]
        public string Name { get; set; }

        [DataMember]
        public string Sex { get; set; }

        [DataMember]
        public string Age { get; set; }
    }
}

六、根据服务器上操作系统的版本，选择进入到win32还是win64，开启ActiveMQ服务。

七、然后启动我们程序，进行测试。
