ActiveMQ将过期消息移动到DLQ队列的时间取决于消息的过期时间设置和队列的配置。以下是一种解决方法的代码示例:
ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616");
connectionFactory.setRedeliveryPolicy(redeliveryPolicy);
Connection connection = connectionFactory.createConnection();
connection.start();
Session session = connection.createSession(false, Session.CLIENT_ACKNOWLEDGE);
Queue destination = session.createQueue("myQueue");
MessageProducer producer = session.createProducer(destination);
TextMessage message = session.createTextMessage("Hello World!");
message.setJMSExpiration(System.currentTimeMillis() + 5000); // 设置消息过期时间
producer.send(message);
MessageConsumer consumer = session.createConsumer(destination);
TextMessage receivedMessage = (TextMessage) consumer.receive();
System.out.println("Received message: " + receivedMessage.getText());
以上代码示例中,当消息的过期时间到达时,ActiveMQ会自动将消息移动到DLQ队列。DLQ队列是用于存储过期或无法传递的消息的特殊队列。您可以根据自己的需求进行配置和调整。
