在c# . net中访问activemq统计插件

我正在尝试访问c#中的activemq统计数据,以以下示例为例:
http://activemq.apache.org/statisticsplugin.html我尝试了很多方法,但我收到的MapMessage是空的或抛出异常,如"不能将AMQMessage转换为MapMessage"
这是我的班级:
public class Statistics
{
private readonly IConnectionFactory connectionFactory;
private readonly IConnection connection;
private readonly ISession session;
public Statistics( string brokerUri)
{
this.connectionFactory = new ConnectionFactory(brokerUri);
this.connection = connectionFactory.CreateConnection();
this.connection.Start();
this.session = connection.CreateSession();
}
public void GetStats()
{
// Crear consumidor
try
{
// Creo una cola y consumidor
IDestination queueReplyTo = session.CreateTemporaryQueue();
IMessageConsumer consumer = session.CreateConsumer(queueReplyTo);
// Crear cola y productor
ActiveMQQueue newQueue = new ActiveMQQueue("ActiveMQ.Statistics.Destination.TEST1");
IMessageProducer producer = session.CreateProducer(null);
// Crear cola monitorizada
string listeningQueue = "TEST1";
ActiveMQQueue query = new ActiveMQQueue(listeningQueue);
// Mandar mensaje vacío y replicar
IMessage msg = session.CreateMessage();
producer.Send(newQueue, msg);
msg.NMSReplyTo = queueReplyTo;
producer.Send(query, msg);
// Recibir
IMapMessage reply = (IMapMessage)consumer.ReceiveNoWait();
if (reply != null)
{
IPrimitiveMap statsMap = reply.Body;
foreach (string statKey in statsMap.Keys)
{
Console.WriteLine("{0} = {1}", statKey, statsMap[statKey]);
}
}
}
catch (Exception e)
{
var t = e.Message + " " + e.StackTrace;
}
}
}
我的错误在哪里?提前感谢
你可以试试这个吗:
public class Statistics
{
private readonly IConnectionFactory connectionFactory;
private readonly IConnection connection;
private readonly ISession session;
public Statistics( string brokerUri)
{
this.connectionFactory = new ConnectionFactory(brokerUri);
this.connection = connectionFactory.CreateConnection();
this.connection.Start();
this.session = connection.CreateSession();
}
public void GetStats()
{
// Crear consumidor
try
{
// Creo una cola y consumidor
IDestination queueReplyTo = session.CreateTemporaryQueue();
IMessageConsumer consumer = session.CreateConsumer(queueReplyTo);
// Crear cola monitorizada
string listeningQueue = "TEST1";
ActiveMQQueue testQueue = session.GetQueue(listeningQueue);
// Crear cola y productor
ActiveMQQueue query = session.GetQueue("ActiveMQ.Statistics.Destination.TEST1");
IMessageProducer producer = session.CreateProducer(null);
// Mandar mensaje vacío y replicar
IMessage msg = session.CreateMessage();
producer.Send(testQueue, msg);
msg.NMSReplyTo = queueReplyTo;
producer.Send(query, msg);
// Recibir
IMapMessage reply = (IMapMessage)consumer.Receive();
if (reply != null)
{
IPrimitiveMap statsMap = reply.Body;
foreach (string statKey in statsMap.Keys)
{
Console.WriteLine("{0} = {1}", statKey, statsMap[statKey]);
}
}
}
catch (Exception e)
{
var t = e.Message + " " + e.StackTrace;
}
}
}
