我正在尝试使用ConfirmListener,但执行永远不会到达其方法。我是这样做的:
channel.addConfirmListener(new ConfirmListener() {
public void handleNack(long deliveryTag, boolean multiple) throws IOException {
System.out.println("Not ack received");
}
public void handleAck(long deliveryTag, boolean multiple) throws IOException {
System.out.println("Ack received");
}
});
channel.exchangeDeclare(directExchangeName, directExchangeType, DURABLE, AUTO_DELETE, arguments);
channel.queueBind(directQueueName, directExchangeName, routingKey);
// AUTO_ACK = false
channel.basicConsume(directQueueName, AUTO_ACK, routingKey, directConsumer);
然后我用这个发表:
channel.basicPublish(directExchangeName, routingKey, MANDATORY, properties, message.getBytes());
后来我用这个消费了:
@Override
public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException {
// Send ack
channel.basicAck(envelope.getDeliveryTag(), false);
}
我做错了什么?
谢谢,欢呼。
答案 0 :(得分:5)
呼叫
channel.confimSelect();
启用发布者确认。
但是我想知道你是否也希望在消费者处理消息时调用addConfirmListener。用于发布的ConfirmListener在接受消息时由服务器触发,它与消费者的确认无关。
