Question

我是ActiveMQ的新手，我需要创建spring boot aplication，其中publis activeMQ队列。因此我创建了简单的SpringBoot应用程序

@SpringBootApplication
@EnableJms
public class Application {

  @Bean 
  JmsListenerContainerFactory<?> myJmsContainerFactory(ConnectionFactory connectionFactory) {
      SimpleJmsListenerContainerFactory factory = new SimpleJmsListenerContainerFactory();
      factory.setConnectionFactory(connectionFactory);
      return factory;
  }

  public static void main(String[] args) {
      FileSystemUtils.deleteRecursively(new File("activemq-data"));
      // Launch the application
      ApplicationContext context = SpringApplication.run(Application.class, args);
      System.out.println(" ************************ Asyn queue start ************************ ");        
  }
}

然后我也创建了一个Listneres：

@Component
public class Receiver {

    @Autowired
    ConfigurableApplicationContext context;


    @JmsListener(destination = "mailbox-destination", containerFactory = "myJmsContainerFactory")
    public void receiveMessageFromMailbox(String message) {
        System.out.println("Received <" + message + "> mailbox");
        //context.close();
        FileSystemUtils.deleteRecursively(new File("activemq-data"));
    }

    @JmsListener(destination = "testqueue-destination", containerFactory = "myJmsContainerFactory")
    public void receiveMessageFromTestQueue(String message) {
        System.out.println("Received <" + message + "> testqueue");
        //context.close();
        FileSystemUtils.deleteRecursively(new File("activemq-data"));
    }
}

启动后，看起来没问题。

为了测试，我创建了一个简单的测试：

public class Testing {

  public static void main(String[] args) throws JMSException {
      try {
          // Create a ConnectionFactory
          ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("vm://localhost");
          // Create a Connection
          Connection connection = connectionFactory.createConnection();
          connection.start();
          // Create a Session
          Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
          // Create the destination (Topic or Queue)
          Destination destination = session.createQueue("testqueue-destination");
          // Create a MessageProducer from the Session to the Topic or Queue
          MessageProducer producer = session.createProducer(destination);
          producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
          // Create a messages
          String text = "Hello world! From: " + Thread.currentThread().getName() + " : ";
          TextMessage message = session.createTextMessage(text);
          // Tell the producer to send the message
          System.out.println("Sent message: "+ message.hashCode() + " : " + Thread.currentThread().getName() + " : " + message);
          producer.send(message);
          // Clean up
          session.close();
          connection.close();
      } catch (Exception e) {
          System.out.println("Caught: " + e);
          e.printStackTrace();
      }
  }
}

但是当我运行Testing.main时，会发生错误：

[main] DEBUG org.apache.activemq.broker.jmx.ManagementContext - 无法创建本地注册表 java.rmi.server.ExportException：端口已在使用中：1099;嵌套异常是： java.net.BindException：已在使用的地址：JVM_Bind at sun.rmi.transport.tcp.TCPTransport.listen（TCPTransport.java:341） at sun.rmi.transport.tcp.TCPTransport.exportObject（TCPTransport.java:249） at sun.rmi.transport.tcp.TCPEndpoint.exportObject（TCPEndpoint.java:411） at sun.rmi.transport.LiveRef.exportObject（LiveRef.java:147） at sun.rmi.server.UnicastServerRef.exportObject（UnicastServerRef.java:208） at sun.rmi.registry.RegistryImpl.setup（RegistryImpl.java:152） at sun.rmi.registry.RegistryImpl。（RegistryImpl.java:112）在java.rmi.registry.LocateRegistry.createRegistry（LocateRegistry.java:239）在org.apache.activemq.broker.jmx.ManagementContext.createConnector（ManagementContext.java:418） at org.apache.activemq.broker.jmx.ManagementContext.findTigerMBeanServer（ManagementContext.java:363）在org.apache.activemq.broker.jmx.ManagementContext.findMBeanServer（ManagementContext.java:330）在org.apache.activemq.broker.jmx.ManagementContext.getMBeanServer（ManagementContext.java:172）在org.apache.activemq.broker.jmx.ManagementContext.start（ManagementContext.java:80）在org.apache.activemq.broker.BrokerService.startManagementContext（BrokerService.java:2031）在org.apache.activemq.broker.BrokerService.start（BrokerService.java:477）

我认为问题出在测试方法上。但我不知道什么是不正确的。有人可以帮助我吗？感谢。

Answer 1

您是否尝试运行netstart命令来检查端口是否正在使用？

对于linux netstat -pnlt | grep 1099

对于windows netstat -np TCP |找到“1099”

Answer 2

我知道SpringBoot应用程序正在使用该端口。 SpringBoot应用程序启动后，将打印以下日志：

[           main] o.apache.activemq.broker.BrokerService   : Using Persistence Adapter: MemoryPersistenceAdapter
[           main] o.apache.activemq.broker.BrokerService   : ActiveMQ 5.4.2 JMS Message Broker (localhost) is starting

[           main] c.c.e.asynqueue.spring.Application       : Started Application in 3.117 seconds (JVM running for 4.52)

但我假设我可以通过以下代码连接到经纪人：

ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("vm://localhost");
// Create a Connection
Connection connection = connectionFactory.createConnection();
connection.start();

Spring Boot ActiveMQ - 已在使用的端口：1099
