本文使用C#实现ActiveMQ消息队列功能。
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。
最后附上源码
