Question

我现在使用activeMQ tcp // localhost 网址安静一段时间，我没有遇到任何问题。目前，我正在尝试使用＆＃34; vm // localhost ＆＃34;连接器，但我收到生产者的消息有问题。我使用的是春靴，生产商和消费者都在不同的罐子里。我的消费者正在收到一条空消息。我错过了什么吗？下面是我的代码（从apache网站获取）。提前致谢

Producer.jar

ActiveMQConnectionFactory connectionFactory = 
new ActiveMQConnectionFactory("vm://localhost");
Connection connection = connectionFactory.createConnection();
connection.start();
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
Destination destination = session.createQueue("TEST.FOO");
MessageProducer producer = session.createProducer(destination);
producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);

String text = "Hello world! From: " + Thread.currentThread().getName() + " : " + this.hashCode();
TextMessage message = session.createTextMessage(text);

System.out.println("Sent message: " + message.hashCode() + " : " + Thread.currentThread().getName());
producer.send(message);

session.close();
connection.close();

Consumer.jar

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

connection.setExceptionListener(this);

Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
Destination destination = session.createQueue("TEST.FOO");

MessageConsumer consumer = session.createConsumer(destination);

// Wait for a message
Message message = consumer.receive(10000);

if (message instanceof TextMessage) {
    TextMessage textMessage = (TextMessage) message;
    String text = textMessage.getText();
    System.out.println("Received 1: " + text);
} else {
    System.out.println("Received 2: " + message);
}

consumer.close();
session.close();
connection.close();

我确定，vm是VM内部的传输！并且无法在其外部访问，因此解决方案是2个客户端中的一个需要使用vm传输，另一个使用vm传输启动tcp和ActiveMQ，或者将2个组件嵌入到同一个VM中。

看到我对同一个用例的另一个答案 How to send Jms message from one spring-boot application to another when both apps use embedded activemq

未使用ActiveMQ VM Transport从生产者接收消息
