ActiveMQ收发消息

1.下载ActiveMQ 

地址:http://activemq.apache.org/activemq-5153-release.html

2.运行ActiveMQ 
解压缩apache-activemq-5.15.3-bin.zip，然后双击apache-activemq-5.15.3\bin\win64\activemq.bat运行ActiveMQ程序。 

启动ActiveMQ以后，登陆：http://localhost:8161/admin/，创建一个Queue，命名为FirstQueue。 

3.创建项目,导入所需要的Jar包

结构如下:

Receiver.java

package com.deniel.test;

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

import org.apache.activemq.ActiveMQConnectionFactory;

/**
 * 点对点模式--消息接收 单连接、消息不持久化、无事务、消息自动确认接收
 * 
 * @Author Deniel
 * @Date 2018.5.12
 */
public class Receiver {

	public static void main(String[] args) {
		ConnectionFactory connFactory;
		Connection conn = null;
		Session session = null;
		Destination destination;
		MessageConsumer consumer;

		try {
			connFactory = new ActiveMQConnectionFactory("admin", "admin", "tcp://127.0.0.1:61616");

			conn = connFactory.createConnection();
			conn.start();
			session = conn.createSession(Boolean.FALSE, // 不开启事务
					Session.AUTO_ACKNOWLEDGE); // 消息自动确认
			destination = session.createQueue("FirstQueue");
			consumer = session.createConsumer(destination);

			long startTime = System.currentTimeMillis();
			int i = 1;
			do {
				TextMessage message = (TextMessage) consumer.receive(100000);
				if (message != null) {
					System.out.println(i + " , 收到消息为： " + message.getText());
					i++;
				} else {
					System.out.println(i + " , 收到消息为null..... ");
				}
			} while (i <= 1000000);

			long endTime = System.currentTimeMillis();
			long diff = endTime - startTime;
			long diffSeconds = diff / 1000;

			System.out.print("receiver use time: " + diffSeconds + " seconds.");
		} catch (Exception e) {
			e.printStackTrace();
		} finally {
			if (session != null) {
				try {
					session.close();
				} catch (JMSException e) {
					e.printStackTrace();
				}
			}
			if (conn != null) {
				try {
					conn.close();
				} catch (JMSException e) {
					e.printStackTrace();
				}
			}
		}
	}
}
