尝试连接简单的JMX监控。托管应用程序和监视工具位于同一服务器上。尝试连接错误时

在服务器上，打开访问权限

 private static void startJmxServer() throws MalformedURLException, IOException {

        Map<String, Object> props = new HashMap<String, Object>();
        RemouteAuthentificator auth = new RemouteAuthentificator();
        props.put("jmx.remote.authenticator", auth);

        JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:22414/MServer");
        MBeanServer mbeanSrv = ManagementFactory.getPlatformMBeanServer();
        JMXConnectorServer server = JMXConnectorServerFactory.newJMXConnectorServer(url, props, mbeanSrv);
        server.start();
        log.info("JMX RMI Agent has been bound on address: " + url);
    }

在Tomcat下的管理工具中，尝试连接

static private MBeanServerConnection makeJmxConnection(String objectName)
    {
    // objectName = “MServer:name=Settings”;
        MBeanServerConnection mConnect = null;
        try
        {
            String[] credentials = new String[] {"server", "password"};
            Map<String, String[]> props = new HashMap<String, String[]>();
            props.put("jmx.remote.credentials", credentials);

            JMXServiceURL url = new JMXServiceURL(“service:jmx:rmi:///jndi/rmi://localhost:22414/MServer”);
            jmxc = JMXConnectorFactory.connect(url, props);
            mConnect = jmxc.getMBeanServerConnection();
            mbeanName = new ObjectName(objectName);
        }
        catch(Exception e)
        {
            log.fatal("", e);
        }

        return mConnect;
    }

并试图通过外部IP连接。结果是一样的。

我不知道你在哪里设置你的号码。你在哪里这么短的代码

String host = "localhost";  // or some x.y.z
int port = setyourPortNumber;
String url = "service:jmx:rmi:///jndi/rmi://localhost:22414/MServer"; // where you get services

我希望它可以帮助你理解

jmx无法连接到localhost
