我在骆驼2.9.0。我能够在 JConsole 中查看正在运行的进程的 MBean 数据（路由、处理器等）。
我需要在我们的用户界面中显示相同的内容。当我尝试获取属性值时，出现以下错误。
注意 - 属性“EndpointUri”正在获取正确的值。
问题在于“FirstExchangeCompletionTime”。所以我的结论是，旋转服务器连接可能没有任何问题。当我们在 Camel.1.6.4 时，属性“FirstExchangeCompletedTimestamp”的同一行代码过去可以正常工作。Camel 1.6.4 之后的 JMX 设置是否有任何变化？
我们在 JMX 设置中使用以下属性：
-Dorg.apache.camel.jmx.disabled=false
-Dorg.apache.camel.jmx.rmiConnector.registryPort=2001
错误：

我们正在通过MBeanServerConnection::getAttribute("X")方法获取值。我浏览了骆驼源代码，这些属性是通过 org.apache.camel.management.mbean.Statistic.
我试过（非静态方式） -
MBeanServerConnection::getAttribute(qName, "org.apache.camel.firstExchangeCompletedTimestamp")
MBeanServerConnection::getAttribute(qName, "firstExchangeCompletedTimestamp")
但似乎没有一个工作。请帮忙。
