1、MBean接口

public interface TestJMXMBean {
    public String sayHello();
    public String getName();
}

2、MBean实现

public class TestJMX implements TestJMXMBean {

    public String sayHello() {
        System.out.println("Hello!!!");
        return "Hello!!!";
    }

    public String getName() {
        return "caililiang";
    }
}

3、MBean代理

import java.lang.management.ManagementFactory;
import java.rmi.RemoteException;
import java.rmi.registry.LocateRegistry;

import javax.management.MBeanServer;
import javax.management.MalformedObjectNameException;
import javax.management.ObjectName;
import javax.management.remote.JMXConnectorServer;
import javax.management.remote.JMXConnectorServerFactory;
import javax.management.remote.JMXServiceURL;

public class TestJMXAgent {
    public static void main(String[] args) {
        TestJMXAgent agent = new TestJMXAgent();
        try {
            agent.startMBean(9999);
        } catch (NullPointerException e) {
            e.printStackTrace();
        }
    }
    public static void startMBean(int port){
        try {
            MBeanServer server = ManagementFactory.getPlatformMBeanServer();
            ObjectName testMBeanName = new ObjectName("jmxBean:name=TestJMX");
            server.registerMBean(new TestJMX(), testMBeanName);
            LocateRegistry.createRegistry(port);
            JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:"+port+"/jmxrmi/TestJMX");
            JMXConnectorServer jcs = JMXConnectorServerFactory.newJMXConnectorServer(url, null, server);
            jcs.start();
            System.out.println("service:jmx:rmi:///jndi/rmi://localhost:"+port+"/jmxrmi/TestJMX ----start");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

4、MBean客户端代码

import java.io.IOException;
import java.net.MalformedURLException;

import javax.management.MBeanServerConnection;
import javax.management.MBeanServerInvocationHandler;
import javax.management.MalformedObjectNameException;
import javax.management.ObjectName;
import javax.management.remote.JMXConnector;
import javax.management.remote.JMXConnectorFactory;
import javax.management.remote.JMXServiceURL;

public class TestJMXClient {

    public static void main(String[] args) {
        TestJMXClient c = new TestJMXClient();
        try {
            String name =c.getName();
        } catch (MalformedObjectNameException e) {
            e.printStackTrace();
        } catch (NullPointerException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    
    public String getName() throws IOException, MalformedObjectNameException, NullPointerException{
        JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:9999/jmxrmi/TestJMX");
        JMXConnector jmxc = JMXConnectorFactory.connect(url,null);
        MBeanServerConnection mbsc = jmxc.getMBeanServerConnection();
        ObjectName mbeanName = new ObjectName("jmxBean:name=TestJMX");
        TestJMXMBean proxy = MBeanServerInvocationHandler.newProxyInstance(mbsc, mbeanName, TestJMXMBean.class, false);
        String name = proxy.getName();
        if(jmxc!=null){jmxc.close();}
        return name;
    }
}
