我有以下消费者代码（来自here），当我像这样在Eclipse中运行它时，它可以正常运行：
Right Click on Project -->Run As --> Springboot App
我可以看到这行代码System.out.println("Received message '" + textMessage.getText()从ActiveMQ队列中打印消息。
但是，当我将项目作为WAR部署到Tomcat中时，看不到运行相同的代码。我的意思是，消息停留在队列中并且不会被打印。我期望，只要我继续将消息添加到队列中，它就会继续打印这些消息，但它不能像这样工作。我在这里做错了什么？
public class Consumer {
// URL of the JMS server
private static String url = ActiveMQConnection.DEFAULT_BROKER_URL;
// default broker URL is : tcp://localhost:61616"
// Name of the queue we will receive messages from
private static String subject = "VALLYSOFTQ";
public static void main(String[] args) throws JMSException {
// Getting JMS connection from the server
ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url);
Connection connection = connectionFactory.createConnection();
connection.start();
// Creating session for seding messages
Session session = connection.createSession(false,
Session.AUTO_ACKNOWLEDGE);
// Getting the queue 'VALLYSOFTQ'
Destination destination = session.createQueue(subject);
// MessageConsumer is used for receiving (consuming) messages
MessageConsumer consumer = session.createConsumer(destination);
// Here we receive the message.
// By default this call is blocking, which means it will wait
// for a message to arrive on the queue.
Message message = consumer.receive();
// There are many types of Message and TextMessage
// is just one of them. Producer sent us a TextMessage
// so we must cast to it to get access to its .getText()
// method.
if (message instanceof TextMessage) {
TextMessage textMessage = (TextMessage) message;
System.out.println("Received message '" + textMessage.getText()
+ "'");
}
connection.close();
}
}
