ActiveMQ (ii) - the installation and basic use ActiveMQ

First, the installation

after a successful start

Second, create an instance of the test ActiveMQ

• Dependent on the desired configuration Maven

  <dependency>
  <groupId>org.apache.activemq</groupId>
  <artifactId>activemq-all</artifactId>
  <version>5.9.0</version>
  </dependency>
  <dependency>
  <groupId>org.apache.xbean</groupId>
  <artifactId>xbean-spring</artifactId>
  <version>3.16</version>
  </dependency>

• Send a message

  public class QueueSender {
  public static void main(String[] args) throws Exception{
      //连接工厂
      ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616");
      Connection connection = connectionFactory.createConnection();
      connection.start();
  
      //带事务的session
      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++) {
          TextMessage message = session.createTextMessage("message--"+i);
          Thread.sleep(1000);
          //通过消息生产者发出消息
          producer.send(message);
      }
      session.commit();
      session.close();
      connection.close();
  }
  }

The method of operating main console output:

This message is sent that go of it?

• Message received

  public class QueueReceive {
  public static void main(String[] args) throws Exception{
      //连接工厂
      ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616");
      Connection connection = connectionFactory.createConnection();
      connection.start();
  
      //带事务的session，并且自动签收
      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++;
          TextMessage message = (TextMessage) consumer.receive();
          session.commit();
          System.out.println("收到的消息是："+message.getText());
      }
      session.close();
      connection.close();
  }
  }

  Run the main method
  

Then look at the server sends a message has been received will be processed.
