JMX 的一个简单例子

废话不多说，上代码：

HelloWorldMBean接口

package com.acxiom.bilyao;

public interface HelloWorldMBean {

	public void setGreeting(String greeting);
	
	public String getGreeting();
	
	public void sayHello();
	
}

HelloWorld

package com.acxiom.bilyao;

import javax.management.Notification;
import javax.management.NotificationBroadcasterSupport;

public class HelloWorld extends NotificationBroadcasterSupport 
	implements HelloWorldMBean {
	
	private String greeting = null;
	
	public HelloWorld() {
		this.greeting = "Hello World! I am a Standard MBean";
	}

	public HelloWorld(String greeting) {
		this.greeting = greeting;
	}
	
	@Override
	public void setGreeting(String greeting) {
		this.greeting = greeting;
		
		Notification notification = new Notification(
				"com.acxiom.bilyao.helloWorld.test", this, -1,
				System.currentTimeMillis(), greeting);
		sendNotification(notification);
	}

	@Override
	public String getGreeting() {
		return greeting;
	}

	@Override
	public void sayHello() {
		System.out.println(greeting);
	}

}

HelloAgent

package com.acxiom.bilyao;

import java.lang.management.ManagementFactory;

import javax.management.MBeanServer;
import javax.management.Notification;
import javax.management.NotificationListener;
import javax.management.ObjectName;

import com.sun.jdmk.comm.HtmlAdaptorServer;

public class HelloAgent implements NotificationListener{

	private MBeanServer mbs = null;
	
	public HelloAgent() {
		mbs = ManagementFactory.getPlatformMBeanServer();
		//mbs = MBeanServerFactory.createMBeanServer("HelloAgent");
		
		HtmlAdaptorServer adapter = new HtmlAdaptorServer();
		
		HelloWorld hw = new HelloWorld();
		ObjectName helloName = null;
		ObjectName adapterName = null;
		
		try {
			helloName = new ObjectName("HelloAgent:name=helloworld");
			adapterName = new ObjectName("HelloAgent:name=htmladapter,port=8000");
			
			adapter.setPort(8000);
			mbs.registerMBean(adapter, adapterName);
			adapter.start();
			
			mbs.registerMBean(hw,helloName);
			
			hw.addNotificationListener( this, null, null );
		} catch(Exception e) {
			e.printStackTrace();
		}
	}
	
	
	private static void waitForEnterPressed() {
		try {
			System.out.println("Press <Enter> to continue...");
			System.in.read();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
	
	public static void main(String[] args) {
		HelloAgent ha = new HelloAgent();
		System.out.println("Hello Agent is running...");
		HelloAgent.waitForEnterPressed();
	}

	@Override
	public void handleNotification(Notification notif, Object handback) {
		System.out.println( "Receiving notification..." );
		System.out.println( notif.getType() );
		System.out.println( notif.getMessage());
	}
}
