ActiveMQ初識

第一次學習使用ActiveMQ，安裝環境windows10

安裝步驟：

1：下載apache-activemq-5.15.4-bin.zip

2：解壓即可

安裝完成後的目錄結構：

啓動在bin目錄下，對應的有兩個文件夾，32和64的根據自己電腦操作系統選擇相應目錄

樓主的是win64，進入目錄雙擊activemq.bat即可啓動

驗證是否啓動成功訪問：http://localhost:8161/ 進入後臺管理系統

登陸密碼默認是：admin/admin

ActiveMQ啓動默認開啓了兩個端口：8161和61616

8161端口：是後臺管理端口  ，可在conf/jetty.xml中修改

61616端口：是java開發連接的端口，可在/conf/activemq.xml

代碼測試：

maven依賴：

<dependency>
     <groupId>org.apache.activemq</groupId>
     <artifactId>activemq-core</artifactId>
     <version>5.5.0</version>
</dependency>

生產者：

package com.test.mq.queue;

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

import org.apache.activemq.ActiveMQConnectionFactory;

public class produceMq {
	private static final String SUBJECT = "test-activemq-queue";
	//連接賬號
    private static String userName = "admin";
    //連接密碼
    private static String password = "admin";
    //連接地址
    private static String brokerURL = "tcp://localhost:61616";
	public static void main(String[] args) throws JMSException {
		//初始化連接工廠  
		ConnectionFactory connectionFactory = new 
                     ActiveMQConnectionFactory(userName,password,brokerURL);
		//獲得連接
		Connection conn = connectionFactory.createConnection();
		//啓動連接
		conn.start();
		//創建Session，此方法第一個參數表示會話是否在事務中執行，第二個參數設定會話的應答模式
		Session session = conn.createSession(true, Session.AUTO_ACKNOWLEDGE);
		//創建隊列
		Destination dest = session.createQueue(SUBJECT);
		//createTopic方法用來創建Topic
		//session.createTopic("TOPIC");
		//通過session可以創建消息的生產者
		MessageProducer producer = session.createProducer(dest);
//		producer.setDeliveryMode(DeliveryMode.PERSISTENT);持久化
		for (int i=0;i<100;i++) {
			//初始化一個mq消息
			TextMessage message = session.createTextMessage("hello active mq 中文" + i);
			//發送消息
			producer.send(message);//
		}
		session.commit();
		session.close();
		//關閉mq連接
		conn.close();
	}
}
