activeMQ初体验

企业开发 2018-05-11 13:14:59 阅读次数: 0

1 首先到官网下载activeMq       http://activemq.apache.org/

   下载压缩包，由于是做实验，暂时用简单的windows bin zip包

   解压到根目录，在bin下，执行命令，可以用cmd或者双击点击activemq

   访问 http://localhost:8161/   用户名密码默认是admin  /admin 

   这样代表消息服务器启动好了，当然暂时用的是内置服务器jetty

2 下面做个实验

    利用IDE工具或者其他工具建2个类，一个是生产者类，一个是消费者类，内部有写注释

  

package activeMq;

import java.util.Date;

import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.Destination;
import javax.jms.MapMessage;
import javax.jms.MessageProducer;
import javax.jms.Session;

import org.apache.activemq.ActiveMQConnectionFactory;

/**
 * jms 发送代码 生产者
 * @author zxg
 * @version $Id: Provider.java, v 0.1 2015年6月11日 下午4:42:33 zxg Exp $
 */
public class Provider {
  public static void main(String[] args) throws Exception{
          ConnectionFactory connectionFactory = new ActiveMQConnectionFactory();  
        
          Connection connection =connectionFactory.createConnection();  
          connection.start();
          /** 1、AUTO_ACKNOWLEDGE 是自动确认模式，不需客户端进行确认
           *  2、CLIENT_ACKNOWLEDGE   客户端进行确认
              3、DUPS_OK_ACKNOWLEDGE  允许重复消息，
          */
          Session session = connection.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE);  
          Destination destination = session.createQueue("my-queue");  
          MessageProducer producer = session.createProducer(destination);  
          
          for(int i=0; i<3; i++) {  
              MapMessage message = session.createMapMessage();  
              message.setLong("count", new Date().getTime());  
              Thread.sleep(1000);  
              //通过消息生产者发出消息  
              producer.send(message);  
          }  
          session.commit();  
          session.close();  
          connection.close();  
}
}

  下面是 消费者类

package activeMq;

import java.util.Date;

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

import org.apache.activemq.ActiveMQConnectionFactory;

/**
 * 消费者
 * @author Zxg
 * @version $Id: Consumer.java, v 0.1 2015年6月11日 下午5:03:44 zxg Exp $
 */
public class Consumer {
  public static void main(String[] args) throws Exception{
      ConnectionFactory  connectionFactory = new ActiveMQConnectionFactory();
      Connection connection = connectionFactory.createConnection();
      connection.start();
      final Session session = connection.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE);
      Destination  destination = session.createQueue("my-queue");
      MessageConsumer consumer = session.createConsumer(destination);
      int i = 0 ;
      while(i<3){
          i++;
          MapMessage message = (MapMessage)consumer.receive();
          session.commit();
          System.out.println("收到消息" + new Date(message.getLong("count")));
      }
     session.close();
     connection.close();
}
}

   3 首先执行生产者的main函数，结果可以这么看到

  在看下消息服务器的结果



 

  意思就是有3个入列，因为生产者就生产了三个消息。

然后我们执行下消费者的main函数，结果如下

18:12:47.827 [main] DEBUG o.a.a.t.failover.FailoverTransport - Reconnect was triggered but transport is not started yet. Wait for start to connect the transport.

 再看下消息服务器，刷新下队列




 好了，大概知道意思了，以后细说细节
