解决ActiveMQ消息重传延迟不起作用的方法可能涉及以下步骤和代码示例:
// 创建连接工厂
ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616");
// 创建连接
Connection connection = connectionFactory.createConnection();
// 创建会话
Session session = connection.createSession(false, Session.CLIENT_ACKNOWLEDGE);
// 创建消费者
Destination destination = session.createQueue("your-queue-name");
MessageConsumer consumer = session.createConsumer(destination);
consumer.setMessageListener(new MessageListener() {
@Override
public void onMessage(Message message) {
try {
// 延迟acknowledge
Thread.sleep(5000);
message.acknowledge();
} catch (Exception e) {
e.printStackTrace();
}
}
});
// 启动连接
connection.start();
consumer.setMessageListener(new MessageListener() {
@Override
public void onMessage(Message message) {
try {
// 延迟acknowledge
Thread.sleep(5000);
// 处理消息
if (message instanceof TextMessage) {
TextMessage textMessage = (TextMessage) message;
String text = textMessage.getText();
System.out.println("Received message: " + text);
// 手动确认消息已被处理
message.acknowledge();
} else {
System.out.println("Invalid message received.");
}
} catch (Exception e) {
e.printStackTrace();
// 处理消息失败,可以添加重试逻辑
}
}
});
通过以上步骤和代码示例,您应该能够解决ActiveMQ消息重传延迟不起作用的问题。请根据您的具体需求和环境做适当的修改。
