如何在 JBoss 保险丝中获得 JMX 连接

Question

我尝试从 JBoss 保险丝获取 JMX 连接，以计算 ActiveMQ 中待处理消息的数量，但我无法获取 JMX 连接。它总是以异常结束

JMXServiceURL url = new JMXServiceURL("service:jmx:rmi://0.0.0.0:44444/jndi/rmi://0.0.0.0:1099/karaf-root");
JMXConnector jmxc = JMXConnectorFactory.connect(url);

以下异常：

Answer 1

您缺少所需的凭据。

查看 this tutorial 您需要向 JMXConnectorFactory

提供凭据

Map env = ...;
String[] creds = {"monitorRole", "mrpasswd"};
env.put(JMXConnector.CREDENTIALS, creds);
JMXConnector cc = JMXConnectorFactory.connect(url, env);

Answer 2

这是解决方案

JMXServiceURL url = new JMXServiceURL("service:jmx:rmi://0.0.0.0:44444/jndi/rmi://0.0.0.0:1099/karaf-root");

HashMap<String, String[]> environment = new HashMap<String, String[]>();
String[] creds = { "admin", "admin" };
environment.put(JMXConnector.CREDENTIALS, creds);

JMXConnector jmxc = JMXConnectorFactory.connect(url, environment);
MBeanServerConnection connection = jmxc.getMBeanServerConnection();
