Artemis Message生产者java程序：
initialContext = new InitialContext();
// Step 2. Look-up the JMS topic
Topic topic = (Topic) initialContext.lookup("topic/exampleTopic");
// Step 3. Look-up the JMS connection factory
ConnectionFactory cf = (ConnectionFactory) initialContext.lookup("ConnectionFactory");
// Step 4. Create a JMS connection
connection = cf.createConnection();
// Step 5. Set the client-id on the connection
connection.setClientID("durable-client");
// Step 6. Start the connection
connection.start();
// Step 7. Create a JMS session
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
// Step 8. Create a JMS message producer
MessageProducer messageProducer = session.createProducer(topic);
TextMessage message1 = session.createTextMessage("This is a text message 1");
// Step 11. Send the text message to the topic
messageProducer.send(message1);

当我运行生产者程序时，send会向主题发送消息，其中客户端（spring部分）正在监听此主题，但它无法成功接收消息。
在日志中获取以下跟踪（我也尝试使用简单的消息转换器，但仍面临同样的问题），如果您将检查下面的日志跟踪ActiveMQMessageConsumer正在抛出此异常。
