使用HornetQ(JBoss)在Docker容器上公开的JMS所需的端口

我使用Docker将JMS服务器容器链接到另一个JMS客户端容器。但是当我在docker容器中运行服务器时,客户端无法正确连接到服务器。我在docker上公开了端口443(JMS使用的还有其他端口吗?)

我可以成功创建目标,但不能创建JMS上下文:

String PROVIDER_URL = "https-remoting://MYDOMAIN:443";
...

/** PASSED **/
Destination destination = (Destination) namingContext.lookup(destinationString);

/** HAS ERROR **/
JMSContext context = connectionFactory.createContext(username, password)

这是错误:

我刚刚找到了解决这个问题的方法。我也经历过它。

在您的情况下,问题出在JBoss配置中。就我而言,问题出在Wildfly 8.2中。

您可能在JBoss中使用以下参数: jboss.bind.address = 0.0.0.0

我在wildfly中使用此参数让他接受来自任何IP的外部连接,因为我的Wildfly暴露在互联网上。

问题是,如果你没有指定JBon / Wildfly设置HornetQ应该向正在进行远程插件的JMS客户端报告哪个IP,HornetQ将假设IP是在jboss.bind.address中设置的。在这种情况下,0.0.0.0不是有效的IP。您可能在其日志JBoss中看到以下消息:

  

INFO [org.hornetq.jms.server](ServerService线程池 - 53)   HQ121005:检测到“http-connector”的“主机”值“0.0.0.0”无效   连接器。切换到“hostname.your.server”。如果这个新地址是   不正确请手动配置连接器使用正确   之一。

在这种情况下,HornetQ将使用机器名称中定义的主机。例如,在linux上,它将使用/ etc / hostname。

中定义的内容

还有另一个问题。因为通常主机名不是Internet上的有效主机,所以可以通过DNS服务解析为IP。

然后注意你可能发生的事情:你的JBoss服务器被安排给0.0.0.0绑定,你的HornetQ(嵌入在JBoss中)试图获取这个IP以及它是如何不是一个有效的IP他正在采取您的服务器的主机名。当您的远程JMS客户端(在您的本地网络之外)在您的JBoss上进行插件时,HornetQ向客户端报告他必须在主机YOUR_HOSTNAME_LOCAL_SERVER上寻找HornetQ资源但是当它尝试通过DNS解析此名称时他不能然后发生以下故障:

  

java.nio.channels.UnresolvedAddressException       at sun.nio.ch.Net.checkAddress(Net.java:123)       at sun.nio.ch.SocketChannelImpl.connect(SocketChannelImpl.java:621)       在io.netty.channel.socket.nio.NioSocketChannel.doConnect(NioSocketChannel.java:176)       at io.netty.channel.nio.AbstractNioChannel $ AbstractNioUnsafe.connect(AbstractNioChannel.java:169)       at io.netty.channel.DefaultChannelPipeline $ HeadHandler.connect(DefaultChannelPipeline.java:1008)       at io.netty.channel.DefaultChannelHandlerContext.invokeConnect(DefaultChannelHandlerContext.java:495)       在io.netty.channel.DefaultChannelHandlerContext.connect(DefaultChannelHandlerContext.java:480)       在io.netty.channel.ChannelOutboundHandlerAdapter.connect(ChannelOutboundHandlerAdapter.java:47)       at io.netty.channel.CombinedChannelDuplexHandler.connect(combinedChannelDuplexHandler.java:168)       at io.netty.channel.DefaultChannelHandlerContext.invokeConnect(DefaultChannelHandlerContext.java:495)       在io.netty.channel.DefaultChannelHandlerContext.connect(DefaultChannelHandlerContext.java:480)       at io.netty.channel.ChannelDuplexHandler.connect(ChannelDuplexHandler.java:50)       at io.netty.channel.DefaultChannelHandlerContext.invokeConnect(DefaultChannelHandlerContext.java:495)       在io.netty.channel.DefaultChannelHandlerContext.connect(DefaultChannelHandlerContext.java:480)       在io.netty.channel.DefaultChannelHandlerContext.connect(DefaultChannelHandlerContext.java:465)       at io.netty.channel.DefaultChannelPipeline.connect(DefaultChannelPipeline.java:847)       at io.netty.channel.AbstractChannel.connect(AbstractChannel.java:199)       at io.netty.bootstrap.Bootstrap $ 2.run(Bootstrap.java:165)       at io.netty.util.concurrent.SingleThreadEventExecutor.runAllTask​​s(SingleThreadEventExecutor.java:354)       在io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:353)       at io.netty.util.concurrent.SingleThreadEventExecutor $ 2.run(SingleThreadEventExecutor.java:101)       在java.lang.Thread.run(Thread.java:745)

该问题的解决方案是配置JBoss哪个主机应该通知远程客户端的客户。

在我的情况下,野生蝇的设置如下。必须更改standalone.xml文件:

<subsystem xmlns="urn:jboss:domain:messaging:2.0">    
   <hornetq-server>
      <security-enabled>true</security-enabled>
      <journal-file-size>102400</journal-file-size>

      <connectors>
         <http-connector name="http-connector" socket-binding="http-remote-jms">
            <param key="http-upgrade-endpoint" value="http-acceptor"/>
         </http-connector>
      </connectors>
                ...    
   </hornetq-server> 
</subsystem>

<socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">
...
   <outbound-socket-binding name="http-remote-jms">  
      <remote-destination host="YOUR_REAL_HOSTNAME" port="${jboss.http.port:8080}"/>  
   </outbound-socket-binding>   
</socket-binding-group>

请注意,我没有使用https,因为我无法使用https for JMS。
