HornetQ JMSException：无法创建会话工厂

Question

我正在尝试直接实例化 JMS 资源，而不使用远程 HORNETQ 的 JNDI。

我正在 Eclipse IDE 中运行我的测试代码。设置我的类路径以使用 HornetQ 2.2.5 库。

目标HornetQ是版本2.1.2.Final，我认为它们应该向后兼容，也许我错了？

好的，我已经阅读了在线文档并遵循了在不使用 JNDI 的情况下连接到远程 JMS 服务器的示例。我不断收到以下异常。我不确定我缺少什么，但我相信我已经正确设置了所有内容。有人可以指出我在这里缺少什么吗？提前致谢。

JMSException：无法创建会话工厂

hornetq-configuration.xml 上的连接器是：

  <connector name="netty">
     <factory-class>org.hornetq.core.remoting.impl.netty.NettyConnectorFactory</factory-class>
          <param key="host"  value="${10.100.111.222}"/>
          <param key="port"  value="${hornetq.remoting.netty.port:5445}"/>
  </connector>

接受器是：

  <acceptor name="netty">
     <factory-class>org.hornetq.core.remoting.impl.netty.NettyAcceptorFactory</factory-class>
      <param key="host"  value="${10.100.111.222}"/>
     <param key="port"  value="${hornetq.remoting.netty.port:5445}"/>
  </acceptor>

我的测试代码是： 连接连接=空；

   try
   {
    Queue queue = HornetQJMSClient.createQueue("TESTQ");

    Map<String, Object> connectionParams = new HashMap<String, Object>();
    connectionParams.put(TransportConstants.PORT_PROP_NAME, 5445);
    connectionParams.put(TransportConstants.HOST_PROP_NAME, "10.100.111.222");        

    TransportConfiguration transportConfiguration = new TransportConfiguration(NettyConnectorFactory.class.getName(),
                                                                               connectionParams);
    ConnectionFactory factory = (ConnectionFactory) HornetQJMSClient.createConnectionFactoryWithoutHA(JMSFactoryType.CF, transportConfiguration);
    System.out.println("debug: " + factory.getClass());

    connection = factory.createConnection();

    Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

    MessageProducer producer = session.createProducer(queue);

    TextMessage message = session.createTextMessage("This is a test message");
    System.out.println("Sent message: " + message.getText());

    producer.send(message);

   }
      finally
      {
         if (connection != null)
         {
            try {
                connection.close();
            } catch (JMSException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
         }
      }

我收到以下异常

关于兼容性：我们直到 2.2.5+ 才提供客户端兼容性。如果您在 2.2.2 上尝试客户端，在 2.2.5 上尝试服务器，您可能会遇到版本不匹配的异常。

我们的目标是始终兼容 2.2.5+

并且您的配置中有一个拼写错误：

  <connector name="netty">
     <factory-class>org.hornetq.core.remoting.impl.netty.NettyConnectorFactory</factory-class>
          <param key="host"  value="10.100.111.222"/>
          <param key="port"  value="${hornetq.remoting.netty.port:5445}"/>
  </connector>

我们使用属性和默认值的语法。例如，您可以定义一个变量 MY_IP 并将其用作：

“${MY_IP:10.100.111.222}”

如果 MY_IP 为空，您将得到 10.100.111.222

但“${10.100.111.222}”没有任何意义。
