我正在一个办公项目中，我们需要实现Apache ActiveMQ Artemis进行消息传递。当我尝试使用一个独立的Java项目（通过从生产者发送消息）连接代理时，它可以工作，但是部署在 Tomcat 上的相同代码会产生奇怪的异常（Tomcat 9.0.20）。

初始化上下文时，我正在尝试连接到代理。
我得到频道已断开连接，当代理运行时，我使用生产者和使用者运行独立代码，并且代码正常运行。
有时，也会收到客户端和服务器版本不兼容的异常，如您在上面的错误日志中所见。
确切的例外是什么？对于导致连接失败的异常，我真的一无所知。
编辑：-上下文初始化代码
public class IamContextListener implements ServletContextListener {
@Override
public void contextInitialized(ServletContextEvent paramServletContextEvent) {
logger.log(Level.INFO, "Servlet Context Initializer Called.");
String brokerUrl = Config.getInstance().getProperty(Constants.BROKER_URL);
String username = Config.getInstance().getProperty(Constants.QUEUE_USERNAME);
String password = Config.getInstance().getProperty(Constants.QUEUE_PASSWORD);
QueueMessagePollScheduler.getInstance().initializeService();
}
创建会话代码
TransportConfiguration transportConfiguration = new TransportConfiguration(NettyConnectorFactory.class.getName());
// Create a ConnectionFactory
// this.connectionFactory = ActiveMQJMSClient.createConnectionFactoryWithoutHA(JMSFactoryType.CF,transportConfiguration);
// new ActiveMQConnectionFactory(brokerUrl);
this.connectionFactory = ActiveMQJMSClient.createConnectionFactory(brokerUrl, UUIDGenerator.getInstance().generateStringUUID());
// Create a Connection
this.connection = this.connectionFactory.createConnection(username, password);
// Create a Session
this.session = this.connection.createSession(transacted, Session.AUTO_ACKNOWLEDGE);
this.connection.start();
// Create a MessageProducer from the Session to the Topic or Queue
this.producer = session.createProducer(null);
this.producer.setDeliveryMode(DeliveryMode.PERSISTENT);
}
catch (Exception e) {
Logger.getLogger(this.getClass().getName()).log(Level.SEVERE, e.getMessage(), e);
throw new ActiveMQConectionException(e.getMessage());
}
生产者代码：-
Destination destination = session.createQueue(queueName);
TextMessage message = session.createTextMessage(messageBodyJSON);
producer.send(destination, message);
实际上，相同的代码也适用于Apache Active MQ，但是我的公司希望升级到Apache Active Artemis。
