ActiveMQ 学习

1、apache-activemq-5.9.0-bin

2、运行

3、登陆 密码admin/admin

4、创建Queue

5、信息发送方

package com.liubin.activemq;

import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.DeliveryMode;
import javax.jms.Destination;
import javax.jms.MessageProducer;
import javax.jms.Session;
import javax.jms.TextMessage;

import org.apache.activemq.ActiveMQConnection;
import org.apache.activemq.ActiveMQConnectionFactory;
/*
* ACtiveMQ 信息发送端
*/
public class Sender {
   
    private static final int SEND_NUMBER = 5;

    public static void main(String[] args) {
        // ConnectionFactory ：连接工厂，JMS 用它创建连接
        ConnectionFactory connectionFactory;
        // Connection ：JMS 客户端到JMS Provider 的连接
        Connection connection = null;
        // Session： 一个发送或接收消息的线程
        Session session;
        // Destination ：消息的目的地;消息发送给谁.
        Destination destination;
        // MessageProducer：消息发送者
        MessageProducer producer;
        // TextMessage message;
        // 构造ConnectionFactory实例对象，此处采用ActiveMq的实现jar
        connectionFactory = new ActiveMQConnectionFactory(
                ActiveMQConnection.DEFAULT_USER,
                ActiveMQConnection.DEFAULT_PASSWORD,
                "tcp://localhost:61616");
        try {
            // 构造从工厂得到连接对象
            connection = connectionFactory.createConnection();
            // 启动
            connection.start();
            // 获取操作连接
            session = connection.createSession(Boolean.TRUE,
                    Session.AUTO_ACKNOWLEDGE);
            // 获取session注意参数值是一个服务器的queue，须在在ActiveMq的console配置
            destination = session.createQueue("FirstQueue");
            // 得到消息生成者【发送者】
            producer = session.createProducer(destination);
            // 设置不持久化，此处学习，实际根据项目决定
            producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
            // 构造消息，此处写死，项目就是参数，或者方法获取
            sendMessage(session, producer);
            session.commit();
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                if (null != connection)
                    connection.close();
            } catch (Throwable ignore) {
            }
        }
    }

    public static void sendMessage(Session session, MessageProducer producer)
            throws Exception {
        for (int i = 1; i <= SEND_NUMBER; i++) {
            TextMessage message = session
                    .createTextMessage("ActiveMq 发送的消息" + i);
            // 发送消息到目的地方
            System.out.println("发送消息：" + "ActiveMq 发送的消息" + i);
            producer.send(message);
        }
    }
   
}

6、信息接收方

package com.liubin.activemq;

import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.Destination;
import javax.jms.MessageConsumer;
import javax.jms.Session;
import javax.jms.TextMessage;

import org.apache.activemq.ActiveMQConnection;
import org.apache.activemq.ActiveMQConnectionFactory;

/*
*ActiveMQ 信息接受者
*/
public class Receiver {

     public static void main(String[] args) {
            // ConnectionFactory ：连接工厂，JMS 用它创建连接
            ConnectionFactory connectionFactory;
            // Connection ：JMS 客户端到JMS Provider 的连接
            Connection connection = null;
            // Session： 一个发送或接收消息的线程
            Session session;
            // Destination ：消息的目的地;消息发送给谁.
            Destination destination;
            // 消费者，消息接收者
            MessageConsumer consumer;
            connectionFactory = new ActiveMQConnectionFactory(
                    ActiveMQConnection.DEFAULT_USER,
                    ActiveMQConnection.DEFAULT_PASSWORD,
                    "tcp://localhost:61616");
            try {
                // 构造从工厂得到连接对象
                connection = connectionFactory.createConnection();
                // 启动
                connection.start();
                // 获取操作连接
                session = connection.createSession(Boolean.FALSE,
                        Session.AUTO_ACKNOWLEDGE);
                // 获取session注意参数值是一个服务器的queue，须在在ActiveMq的console配置
                destination = session.createQueue("FirstQueue");
                consumer = session.createConsumer(destination);
                while (true) {
                    //设置接收者接收消息的时间，为了便于测试，这里谁定为100s
                    TextMessage message = (TextMessage) consumer.receive(100000);
                    if (null != message) {
                        System.out.println("收到消息" + message.getText());
                    } else {
                        break;
                    }
                }
            } catch (Exception e) {
                e.printStackTrace();
            } finally {
                try {
                    if (null != connection)
                        connection.close();
                } catch (Throwable ignore) {
                }
            }
        }
}
