ActiveMQ（二）——ActiveMQ的安裝和基本使用

一、安裝

啟動之后成功

二、創建實例測試ActiveMQ

• 配置Maven所需的依賴

  <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>

• 消息發送

  public class QueueSender {
  public static void main(String[] args) throws Exception{
      //連接工廠
      ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616");
      Connection connection = connectionFactory.createConnection();
      connection.start();
  
      //帶事務的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);
          //通過消息生產者發出消息
          producer.send(message);
      }
      session.commit();
      session.close();
      connection.close();
  }
  }

運行main方法，控制臺輸出如下：

那這個消息發送到哪里去了呢？

• 消息接收

  public class QueueReceive {
  public static void main(String[] args) throws Exception{
      //連接工廠
      ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616");
      Connection connection = connectionFactory.createConnection();
      connection.start();
  
      //帶事務的session，并且自動簽收
      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();
  }
  }

  運行main方法
  

此時再看服務器端會發送消息已經被接收處理了。
