将 Wildfly 10.1 Standalone-full-ha.xml 与包含的 ActiveMQ Artemis 1.1.0 一起使用。通过将其添加到 activemq 配置来启用 STOMP：
<acceptor name="stomp-acceptor" factory-class="org.apache.activemq.artemis.core.remoting.impl.netty.NettyAcceptorFactory">
<param name="protocols" value="STOMP"/>
<param name="port" value="${stomp.port:61613}"/>
</acceptor>
基于https://spring.io/guides/gs/messaging-stomp-websocket/部署了一个示例 spring websockets 战争
我在 2 个能够形成集群的独立服务器上运行它。我能够连接到两台服务器并发送消息，但是当我断开其中一个 websocket 时，另一台服务器上会引发以下异常：
16:49:02,377 ERROR [org.apache.activemq.artemis.core.server] (Thread-7 (ActiveMQ-client-global-threads-926891052)) AMQ224037: cluster connection Failed to handle message: java.lang.IllegalStateException: Cannot find binding for ffaa538e-77c3-11e7-ba4b-7b9cb7ee40e2b7e6493a-77c3-11e7-ba4b-7b9cb7ee40e2

我还使用 Wildfly 11 Alpha 和随附的 ActiveMQ Artemis 1.5.3 对此进行了测试，但每次断开 websocket 时都会出现相同的错误。
当我关闭服务器时，我也会收到以下错误，但我不太关心这些，因为它们只在关闭期间发生：

弹簧 websocket 示例有问题吗？
我是否需要更改默认的standalone-full-ha.xml 中的某些内容以使其在集群中正常工作，而不会在客户端断开连接时引发异常？
