使用 Wildlfy 11 嵌入式 Apache Artemis 接收 MQTT 消息

Receiving MQTT message with Wildlfy 11 embedded Apache Artemis

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

当前状态:

  1. 我为 Wildfly 嵌入式 Apache Artemis 添加了 MQTT 协议支持(添加了 "missing" 文件夹和 artemis-mqtt-protocol-.jar 并在 module.xml)

  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"/>
  1. 还添加了 mqtt 到套接字绑定

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

  1. 接下来我写了一个简单的MDB为:


    @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());
            }
        }

    }

  1. 我可以连接到端口 1883 上的服务器,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

看来我在某处遗漏了一些绑定,但我找不到它是什么。有人知道吗?

日志是这样说的:

AMQ221052: Deploying topic jms.topic.testEndpoint

它还说:

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。

看起来有两个问题:

  1. 在 MessageDriven 注释中,GlassFish 使用 mappedName,Wildfly 使用 ActivationConfigProperty(propertyName = "destination" ...。根据 post,我发现两者都很好。所以正确的格式是:


    @MessageDriven(                
        mappedName = "testEndpoint", // GlassFish    
        activationConfig = { 
            @ActivationConfigProperty(propertyName = "destination", 
                                      propertyValue = "testEndpoint"),  // Wildfly
            @ActivationConfigProperty(propertyName = "destinationType",                                                      
                                      propertyValue = "javax.jms.Topic")
    })


  1. 在Wildfly配置中,主题名称应该与整个即对应:

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