使用RabbitMQ C＃AMQ/QPID和WSO2 Message Broker扇出交换

Question

我正在使用RabbitMQ 2.8.7 DotNet客户端以及WSO2 MB 3.2.1。 我的部署环境是Win7 R1 64bit或Win Server 08 R2 64bit。 我遇到了与Exchange有多个连接的问题，因此流向多个使用者的数据在间歇性时间丢失。我们已经尝试将WSO2 MB更新为3.2.3 &将我们的交换改为粉丝来解决这种连接丢失，但遇到了问题。

这将“出现”，该链接是有点关系：

http://wso2-oxygen-tank.10903.n7.nabble.com/Qpid-Authorization-handler-does-not-allow-to-subscribe-td2080.html

我首先想知道，如果这是正确的做法。

其次，我想了解我们在运行时使用扇出接收到的当前错误，因为我们无法访问数据。下面是收到的错误，WSO2 MB日志输出&来自生产者的代码片段。

请告知是否需要更多信息来查明。

错误接收......错误的

我发现试图与Java连接以及时也出现此问题。 对生产者的C＃代码的简单例子如下：

class Send { 

    public static void Main() { 

     string serverAddress = "amqp://" + "192.168.1.12" + ":5672/carbon"; 

      ConnectionFactory factory = new ConnectionFactory(); 

      factory.Uri = serverAddress; 

      using (IConnection connection = factory.CreateConnection()) 

      using (IModel channel = connection.CreateModel()) { 

      channel.QueueDeclare("fanout", false, false, false, null); 

      channel.QueueBind("fanout", "fanout", ""); 

      string message = "Hello World!"; 

      byte[] body = System.Text.Encoding.UTF8.GetBytes(message); 

      channel.BasicPublish("", "hello", null, body); 
      Console.WriteLine(" [x] Sent {0}", message); 
     } 
    } 
} 

Answer 1

在WSO2 MB的交流不会中动态创建的任何名称given.Therefore获得与“扇出”交换这项工作，它需要在qpid-virtualhosts.xml文件中预先声明。否则使用默认的WSO2 MB交换。

看来你没有正确地声明队列需要绑定的交换名称。如果它的队列，默认交换名称申报会是什么样子，

ch.ExchangeDeclare("amq.direct", "direct"); 

如果是主题，'

ch.ExchangeDeclare("amq.topic", "topic");
