javax.management.AttributeNotFoundException

我在骆驼2.9.0。我能够查看在JConsole中运行进程的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“FirstExchangeComplectionTime”。因此，我的结论是，旋转服务器连接可能不会有任何问题。在Camel.1.6.4中，属性“FirstExchangeCompletedTimestamp”的同一行代码可以正常工作。Camel 1.6.4之后，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：

我们通过

MBeanServerConnection:：getAttribute（“X”）

方法获取值。我浏览了Camel源代码，这些属性是通过

org.apache.Camel.management.mbean.Statistic

获得的

我试过（非静态方式）-

---

但似乎都没有起作用。请提供帮助。

确保您正在检查正确的属性值，错误显示“FirstExchangeCompletionTime” ，但该属性称为“FirstExchangeCompletedTimestamp”

有关更多信息，请参阅此单元测试：

是的。我注意到了。这是因为属性名称已更改。我们在骆驼1.6.4之前。成功了。谢谢

MBeanServerConnection::getAttribute(qName, "org.apache.camel.firstExchangeCompletedTimestamp")
MBeanServerConnection::getAttribute(qName, "firstExchangeCompletedTimestamp")
