Artemis STOMP消息未传递到OPENWIRE JMS客户端

Question

我们正试图从ActiveMQ5.x升级到最新的Artemis(2.17)，但我们的一个应用程序让我们很难过。

我们单独运行了一个事务，启用了Artemis STOMP调试，下面是我们看到的：

07:47:42,180 STOMP(/10.0.0.5:40618, f985f04d): IN << StompFrame[command=CONNECT, headers={login=<appid>, passcode=<app-password>}]
07:47:42,196 STOMP(/10.0.0.5:40618, f985f04d):OUT >> StompFrame[command=CONNECTED, headers={session=f985f04d}]
07:47:42,203 STOMP(/10.0.0.5:40618, f985f04d): IN << StompFrame[command=SUBSCRIBE, headers={ack=client, destination=/temp-queue/Reply-604379ee2f900, activemq.prefetchSize=1}]
07:47:42,235 STOMP(/10.0.0.5:40618, f985f04d): IN << StompFrame[command=SEND, headers={expires=1615035162000, destination=/queue/target, content-type=text/plain, reply-to=/temp-queue/Reply-604379ee2f900}, body=<--- message text---> body-bytes=[<--- message bytes --->, size=0]
07:48:42,247 STOMP(/10.0.0.5:40618, f985f04d): IN << StompFrame[command=DISCONNECT, headers={}]

问题的核心似乎是来自上面显示的“send”操作的消息从未到达接收者。我们已经验证了接收者是在线的，并且它响应使用JMS和Openwire连接的其他客户端--但是这个STOMP消息没有被路由到目的地。

如果关闭Artemis并恢复到ActiveMQ5.x，则应用程序可以正常工作。

我们使用默认配置：

<acceptors>

         <!-- useEpoll means: it will use Netty epoll if you are on a system (Linux) that supports it -->
         <!-- amqpCredits: The number of credits sent to AMQP producers -->
         <!-- amqpLowCredits: The server will send the # credits specified at amqpCredits at this low mark -->
         <!-- amqpDuplicateDetection: If you are not using duplicate detection, set this to false
                                      as duplicate detection requires applicationProperties to be parsed on the server. -->
         <!-- amqpMinLargeMessageSize: Determines how many bytes are considered large, so we start using files to hold their data.
                                       default: 102400, -1 would mean to disable large mesasge control -->

         <!-- 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. -->


         <!-- 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</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>

我们是否需要一些神奇的配置来将这些STOMP消息路由到正确的目的地？

Answer 1

第一个问题是消息发送到的目标。如ActiveMQ5.x STOMP文档中所述，send帧的destination标头上使用的/queue/前缀将自动删除。但是，在ActiveMQ Artemis中，这需要通过ActiveMQ Artemis STOMP文档中讨论的anycastprefix参数显式配置，例如：

<acceptor name="stomp">tcp://0.0.0.0:61613?tcpSendBufferSize=1048576;tcpReceiveBufferSize=1048576;protocols=STOMP;useEpoll=true;anycastPrefix=/queue/;multicastPrefix=/topic/</acceptor>

这里还配置了multicastprefix以确保完整性。

一旦配置完成，您的消息将按预期发送到target。

<acceptor name="stomp">tcp://0.0.0.0:61613?tcpSendBufferSize=1048576;tcpReceiveBufferSize=1048576;protocols=STOMP;useEpoll=true;anycastPrefix=/queue/,/temp-queue/;multicastPrefix=/topic/,/temp-topic/</acceptor>

由于您的Stomp客户机使用/temp-queue/指定reply-to标头，而OpenWire客户机也使用此标头，因此您还需要更改OpenWireacceptor，例如：

xml prettyprint-override"><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;anycastPrefix=/temp-queue/;multicastPrefix=/temp-topic/</acceptor>

我打开了ARTEMIS-3164，以实现一个前缀，用于标识ActiveMQ Artemis中的临时资源。
