ActiveMQ-安装和基本使用

1.Windows下安装ActiveMQ

1.1.官网下载ActiveMQ

ActiveMQ官网
 ActiveMQ镜像地址

1.2.解压修改配置文件

apache-activemq-5.15.3\conf\activemq.xml，将0.0.0.0修改为localhost

ps:若出现以下错误闪退无法启动，则因MQ版本和JRE版本不匹配问题导致，更换JRE或者MQ版本即可。这里我降低了MQ的版本解决问题。

ps:如果更换版本依然出现闪退，则可以通过编辑activemq.bat,在末端加上pause，重新启动则可以暂停闪退找出问题

ps:windows系统直接运行activemq.bat闪退,则可尝试使用cms命令行运行activemq-admin.bat start可以解决问题

启动成功后,访问http://localhost:8161/admin，即可登录ActiveMQ管理界面。默认账号admin 密码admin

2.Linux下安装ActiveMQ

2.1 创建目录

cd /usr/local
mkdir activemq

2.2 下载并解压activemq

tar -zxvf apache-activemq-5.13.5-bin.tar.gz

2.3 启动activemq

activemq启动分linux-x86-32和linux-x86-64

cd linux-x86-64
./activemq start

2.4 访问

http://10.102.151.115:8161/admin/

3.ActiveMQ 在Java Api的基本使用

以下是一个使用参考:

3.1 导包

  <!-- activemq 相关maven依赖 -->

      <version>1.2.16</version>
    </dependency>

3.2 API使用

ProducePool

package com.ithzk.activemq;

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

import javax.jms.*;

/** * @author hzk * @date 2018/3/31 */
public class ProducePool {

    private String user = ActiveMQConnection.DEFAULT_USER;
    private String password = ActiveMQConnection.DEFAULT_PASSWORD;
    private String url = ActiveMQConnection.DEFAULT_BROKER_URL;
    private String subject = "mytopic";
    private Destination destination = null;
    private Connection connection = null;
    private Session session = null;
    private MessageProducer messageProducer = null;
    MessageProducer producer = null;

    /** * 初始化 * @throws JMSException */
    public void initialize() throws JMSException {
        ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory(user, password, url);
        connection = activeMQConnectionFactory.createConnection();
        session = connection.createSession(false,Session.AUTO_ACKNOWLEDGE);
        destination = session.createTopic(subject);
        producer = session.createProducer(destination);
        producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
    }

    /** * 发送消息 * @param message * @throws JMSException */
    public void produceMessage(String message) throws JMSException {
        initialize();
        TextMessage textMessage = session.createTextMessage(message);
        connection.start();
        System.out.println("Producer -> Send Message:"+message);
        producer.send(textMessage);
        System.out.println("Producer -> Send Message complete!");
    }

    public void close() throws JMSException {
        System.out.println("Producer -> close connection!");
        if(producer != null){
            producer.close();
        }
        if(session != null){
            session.close();
        }
        if(connection != null){
            connection.close();
        }
    }

}

ProduceTest

package com.ithzk.activemq;

import javax.jms.JMSException;
import java.util.Random;

/** * @author hzk * @date 2018/3/31 */
public class ProduceTest {
    
    public static void main(String[] args) throws JMSException, InterruptedException {
        ProducePool producePool = new ProducePool();
        Random random = new Random();
        for (int i =0;i < 20;i++){
            Thread.sleep(random.nextInt(3)*1000);
            producePool.produceMessage("Hello,ActiveMQ! Number:"+i);
            producePool.close();
        }
        producePool.initialize();

    }
}
