客户端工具MQTT.fx上定义的主题未使用ActiveMQ Artemis消息

2022-07-03 00:00:00 mqtt java spring-boot spring-jms activemq-artemis

我的用例保证使用发布-订阅模型，因此我使用在我的Spring Boot客户端中定义的主题。我已经使用工具MQTT.fx和两个Spring Boot客户端进行了测试。两个Spring Boot客户端能够相互通信，但MQTT.fx客户端只连接到代理，不生成或使用消息。两个Spring Boot客户端都连接到端口61616，而MQTT.fx客户端连接到端口1883。

对于我的项目，我需要让MQTT.fx客户端工作，因为它高度代表打算与服务器一起工作的微控制器。MQTT.fx上的故障就是微控制器上的故障。

我broker.xml文件中的acceptor配置如下所示。

<acceptors>
     <!-- Acceptor for every supported protocol -->
     <acceptor name="artemis">tcp://0.0.0.0:61616?tcpSendBufferSize=1048576;tcpReceiveBufferSize=1048576;amqpMinLargeMessageSize=102400;protocols=CORE,AMQP,STOMP,HORNETQ,MQTT,OPENWIRE;useEpoll=true;amqpCredits=1000;amqpLowCredits=300;amqpDuplicateDetection=true;supportAdvisory=false;suppressInternalManagementObjects=false</acceptor>

     <!-- AMQP Acceptor.  Listens on default AMQP port for AMQP traffic.-->
     <acceptor name="amqp">tcp://0.0.0.0:5672?tcpSendBufferSize=1048576;tcpReceiveBufferSize=1048576;protocols=AMQP;useEpoll=true;amqpCredits=1000;amqpLowCredits=300;amqpMinLargeMessageSize=102400;amqpDuplicateDetection=true</acceptor>

     <!-- STOMP Acceptor. -->
     <acceptor name="stomp">tcp://0.0.0.0:61613?tcpSendBufferSize=1048576;tcpReceiveBufferSize=1048576;protocols=STOMP;useEpoll=true</acceptor>

     <!-- HornetQ Compatibility Acceptor.  Enables HornetQ Core and STOMP for legacy HornetQ clients. -->
     <acceptor name="hornetq">tcp://0.0.0.0:5445?anycastPrefix=jms.queue.;multicastPrefix=jms.topic.;protocols=HORNETQ,STOMP;useEpoll=true</acceptor>

     <!-- MQTT Acceptor -->
     <acceptor name="mqtt">tcp://0.0.0.0:1883?tcpSendBufferSize=1048576;tcpReceiveBufferSize=1048576;protocols=MQTT;useEpoll=true</acceptor>
</acceptors>

Spring Boot客户端通信时的日志如下。首先，向主题server.weatherForecast发送一条消息，然后，经过一些处理后，向AMEBAA000105.device.weatherForecast发送响应。

使用MQTT.fx时的日志如下。最初订阅AMEBAA000105.device.weatherForecast，然后向server.weatherForecast发送消息。本来要接收这些消息的Spring Boot客户端不会接收任何内容，因此不会向AMEBAA000105.device.weatherForecast发送任何内容。当另一个Spring Boot客户端触发将消息从Spring Boot客户端发布到AMEBAA000105.device.weatherForecast时，MQTT.fx不捕获该消息。

以上日志为审核日志。在artemis.log文件中，MQTT.fx不断ping代理。

从artemis.log文件中的MQTT.fx订阅或发布的日志如下

非常感谢您的帮助。

解决方案

您说在测试Spring Boot客户端时，您会向server.weatherForecast发送一条消息，经过一些处理后，会向AMEBAA000105.device.weatherForecast发送一个响应。然而，这是而不是日志显示的。日志显示您分别向jms.topic.server.weatherForecast和jms.topic.AMEBAA000105.device.weatherForecast发送消息。请注意jms.topic.前缀。

我相信这是问题的根源，因为根据日志，MQTT实际上将使用server.weatherForecast和AMEBAA000105.device.weatherForecast。由于这两个客户端没有使用匹配的名称，因此它们永远不能与您的当前配置一起工作。

我的猜测是您正在使用来自您的Spring Boot应用程序的遗留Artemis 1.x客户端，这就是使用jms.topic.前缀的原因。您应该迁移到较新的客户端(例如，与您正在使用的代理版本匹配的客户端)，或者配置anycastPrefix和multicastPrefix以支持旧版1.x客户端。默认的broker.xml有一个说明如何执行此操作的注释：

<!-- Note: If an acceptor needs to be compatible with HornetQ and/or Artemis 1.x clients add
           "anycastPrefix=jms.queue.;multicastPrefix=jms.topic." to the acceptor url.
           See https://issues.apache.org/jira/browse/ARTEMIS-1644 for more information. -->

默认情况下，此注释显示在acceptors块中，但似乎已将其删除，因为它不在您粘贴的XML中。

如果要确认客户端正在使用哪个库，最简单的方法就是检查客户端的环境。但是，如果这不起作用，并且您有权访问代理日志，那么您可以对org.apache.activemq.artemis.core.protocol.core.impl.RemotingConnectionImpl执行enable TRACE logging，然后查看CreateSessionMessage中传递的version。如果是<；131，则它不是2.18.0客户端。
