Java管理扩展(JMX)入门-优快云博客

概念：

JMX（Java Management Extensions，即Java管理扩展）,可通过各种通讯协议，访问被注册Java类的方法，以达到管理Java程序的目的。

例子：

注册类

public class Hello implements HelloMBean {
    private String name;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public void printHello() {
        System.out.println("Hello World, " + name);
    }
    public void printHello(String whoName) {
        System.out.println("Hello , " + whoName);
    }
}

接口类

public interface HelloMBean {
    public String getName();
    public void setName(String name);
    public void printHello();
    public void printHello(String whoName);
}

服务类

import javax.management.MBeanServerFactory;
import javax.management.ObjectName;
import com.sun.jdmk.comm.HtmlAdaptorServer;

public class MBeanRegister {
    public static void main(String[] args) throws Exception {
	//启动MBean注册容器
	MBeanServer mBeanContainer = MBeanServerFactory.createMBeanServer();
	
	//注册自己的MBean
	ObjectName mBeanName = new ObjectName("MBean:name=Hello");
	HelloMBean helloMBean = new Hello();
	mBeanContainer.registerMBean(helloMBean, mBeanName);
	
	//注册Mbean服务器
	ObjectName serverName = new ObjectName("Server:name=HtmlAdaptorServer");
	HtmlAdaptorServer htmlAdaptorServer = new HtmlAdaptorServer();
	htmlAdaptorServer.setPort(8082);
	mBeanContainer.registerMBean(htmlAdaptorServer, serverName);

	//启动MBean服务器
	htmlAdaptorServer.start();
    }
}
