通過JMX訪問Apache ActiveMQ拋出異常

我正在使用新鮮的ActiveMQ 5.8.0安裝，其中我在一個名爲'testing'的隊列中有一條消息。我還更換了ACTIVEMQ_SUNJMX線bin/activemq啓用JMX：通過JMX訪問Apache ActiveMQ拋出異常

ACTIVEMQ_SUNJMX_START="-Dcom.sun.management.jmxremote.port=1099 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false"

然後我通過下面的代碼查詢JMX：訪問所述的mbean時

try { 
     JMXConnector connector = JMXConnectorFactory.connect(new JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi")); 
     connector.connect(); 
     MBeanServerConnection connection = connector.getMBeanServerConnection(); 

     ObjectName mbeanName = new ObjectName("org.apache.activemq:BrokerName=localhost,Type=Broker"); 
     BrokerViewMBean mbean = MBeanServerInvocationHandler.newProxyInstance(connection, mbeanName, BrokerViewMBean.class, true); 

     System.out.println("Id:" + mbean.getBrokerId()); // here the exception will be thrown 
    } 
    catch (Exception x) { 
     x.printStackTrace(); 
    }

拋出異常。

我檢查了那個端口正在偵聽，VisualVM也顯示了我的mbeans，想法？

5.8.0 release page中記錄了bean名稱已更改的事實。

所以，你的對象名應該是這樣的形式：

ObjectName mbeanName = new ObjectName("org.apache.activemq:type=Broker,brokerName=localhost");

是的，這是正確的答案。不幸的是，我發現的所有例子都有5.8版本的發行版 – Dag 2013-04-05 20:44:30

Tim，那麼如何解決由此破解的工具 - 比如HermesJMS和ActiveMQBrowser，我無法使用5.8.0？請幫忙！謝謝！ – 2013-05-16 08:52:52

@OlegKiorsak你有沒有得到它與HermesJMS – Franklin 2014-11-12 05:07:05

出色答卷。在這裏你有一個使用的例子：API Docs

還有一些重要的變化從5.7到5.8。爲JMX服務的默認網址雲來源：

service:jmx:rmi://localhost/jndi/rmi://localhost:1099/jmxrmi

到：

service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi

可愛的問題和答案也一樣，我有一個很難配置了JMX。 ActiveMQ文檔在這方面不是最新的。例如：http://activemq.apache.org/jmx.html不會從5.8.0開始說「SUNJMX」變成「ACTIVEMQ_SUNJMX_START」。

由OP提供的配置，即： ACTIVEMQ_SUNJMX_START =「 - Dcom.sun.management.jmxremote.port = 1099 -Dcom.sun.management.jmxremote.authenticate =假-Dcom.sun.management.jmxremote.ssl = false「

，相應的代碼是真正爲我工作的代碼。謝謝！（我正在使用ActiveMQ 5.8）
