JMX简单例子

一：创建maven项目，在pom.xml里面加入如下依赖

<dependency>
    	<groupId>com.sun.jdmk</groupId>
    	<artifactId>jmxtools</artifactId>
    	<version>1.2.1</version>
    </dependency>

由于该依赖在默认的maven中央仓库无法下载，所以，还必须加入如下仓库

<repositories>
    	<repository>
    		<id>jboss</id>
    		<url>http://repository.jboss.org/maven2/</url>
    	</repository>
    </repositories>

二：创建一个MBean的接口

package com.lala.jmx;
    
    public interface ConfigMBean 
    {
    	public String getBind();
    	
    	public void setBind(String bind);
    	
    	public Integer getPort();
    	
    	public void setPort(Integer port);
    }

实现类：

package com.lala.jmx;
    
    public class Config implements ConfigMBean 
    {
    	private String bind;
    	private Integer port;
    
    	public String getBind() {
    		return bind;
    	}
    
    	public void setBind(String bind) {
    		this.bind = bind;
    	}
    
    	public Integer getPort() {
    		return port;
    	}
    
    	public void setPort(Integer port) {
    		this.port = port;
    	}
    }

创建Agent类

package com.lala.jmx;
    
    import javax.management.MBeanServer;
    import javax.management.MBeanServerFactory;
    import javax.management.ObjectName;
    
    import com.sun.jdmk.comm.HtmlAdaptorServer;
    
    public class ConfigAgent
    {
    	public static void main(String[] args)throws Exception
    	{
    		int port = 8282;
    		MBeanServer server = MBeanServerFactory.createMBeanServer();
            ObjectName configName = new ObjectName("config:name=configure");
            server.registerMBean(new Config(), configName);
            ObjectName adapterName = new ObjectName("config:name=htmladapter");
            HtmlAdaptorServer adapter = new HtmlAdaptorServer();
            server.registerMBean(adapter, adapterName);
            adapter.setPort(port);
            adapter.start();
            System.out.println("server start on port "+port+" .....");
    	}
    }

注意：

config:name=configure  的名字是有一定规则的，格式为：“域名:name=MBean名称”，域名和MBean名称都可以任意取

最后，在浏览器上访问

http://127.0.0.1:8282   单击 config:name=configure 连接即可进入
