java - 使用 Wildlfy 11 嵌入的 Apache Artemis 接收 MQTT 消息

Question

我想在带有嵌入式 Apache Artemis 的 Wildfly 11 中接收 MQTT 消息。

当前状态:

1. 我向 Wildfly 嵌入式 Apache Artemis 添加了 MQTT 协议(protocol)支持(添加了“缺失”文件夹和 artemis-mqtt-protocol-.jar 并在 module.xml 中启用了该协议(protocol))

   <

2. 我正在使用完整的独立配置并为 MTQQ 添加了接受器:

<subsystem xmlns="urn:jboss:domain:messaging-activemq:2.0">
  <server name="default">
        <remote-acceptor name="mqtt-acceptor" socket-binding="mqtt">
          <param name="protocols" value="MQTT"/>
        </remote-acceptor>

主题为:

<jms-topic name="testEndpoint" entries="java:/jms/testEndpoint"/>

还将 mqtt 添加到套接字绑定(bind)

从日志中我可以看到它有效:

AMQ221020: Started Acceptor at 127.0.0.1:1883 for protocols [MQTT]

AMQ221007: Server is now live AMQ221001: Apache ActiveMQ Artemis Message Broker version 1.5.5.jbossorg-008

AMQ221003: Deploying queue jms.queue.DLQ

WFLYMSGAMQ0002: Bound messaging object to jndi name java:/ConnectionFactory

AMQ221003: Deploying queue jms.queue.ExpiryQueue

WFLYMSGAMQ0002: Bound messaging object to jndi name java:jboss/exported/jms/RemoteConnectionFactory

AMQ221052: Deploying topic jms.topic.testEndpoint

接下来我编写了一个简单的 MDB:

    @MessageDriven(
            activationConfig = { @ActivationConfigProperty(propertyName = "destination", 
                                                           propertyValue = "testEndpoint"), 
                                 @ActivationConfigProperty(propertyName = "destinationType", 
                                                           propertyValue = "javax.jms.Topic")
            },
            mappedName = "testEndpoint")
    public class TestEndpoint implements MessageListener {

        private static final Logger logger = Logger.getLogger(TestEndpoint.class.getName());

        public void onMessage(Message message) {
            try {
                logger.debug("message: " + message.getClass().getName());
            } catch (Exception e) {
                logger.debug("exception: " + e.getMessage());
            }
        }

    }

我可以通过端口 1883 连接到服务器，当我向 testEndpoint 发送消息时，我可以在日志中看到:

SESSION CREATED: 63f14f85-0fa2-4fe7-a27b-03ef8e6639a2

Couldn't find any bindings for address=testEndpoint on message=ServerMessage[messageID=962,durable=true,userID=null,priority=0, bodySize=512, timestamp=0,expiration=0, durable=true, address=testEndpoint,properties=TypedProperties[mqtt.message.retain=true,mqtt.qos.level=1]]@749653273

Message ServerMessage[messageID=962,durable=true,userID=null,priority=0, bodySize=512, timestamp=0,expiration=0, durable=true, address=testEndpoint,properties=TypedProperties[mqtt.message.retain=true,mqtt.qos.level=1]]@749653273 is not going anywhere as it didn't have a binding on address:testEndpoint

QueueImpl[name=$sys.mqtt.retain.testEndpoint, postOffice=PostOfficeImpl [server=ActiveMQServerImpl::serverUUID=c58c74d5-ea71-11e7-9621-a434d929f4aa]]@6ff93fb4 doing deliver. messageReferences=0

所以看起来我在某处缺少一些绑定(bind)，但我找不到它是什么。有人有什么想法吗？

Answer 1

日志是这样说的:

AMQ221052: Deploying topic jms.topic.testEndpoint

它还这样说:

Couldn't find any bindings for address=testEndpoint

所以在我看来，这只是“jms.topic.testEndpoint”和“testEndpoint”之间的简单不匹配。
