通过Apache .commons-modeler开发相关的JMX

asdrtu

　　通过Apache 的.commons-modeler组件和JMX 中MBean的描述，是JMX不必实现相关的XxxxMBean的实现，通过反射和MBean描述动态产生相关的MBean的对象和接口。
　　1.JMX的服务对象

package com.easyway.apache.moduler.jmx;
/**
* 备注此处的JMX没有实现相关的XxxMBean的接口
* @author longgangbai
*
*/
public class EasywayService implements IEasywayService {
private String serviceName;
public String getServiceName() {
return serviceName;
}
public void setServiceName(String serviceName) {
this.serviceName = serviceName;
}
/* (non-Javadoc)
* @see com.easyway.apache.moduler.jmx.IEasywayService#printHello()
*/
public void printHello() {
System.out.println("Hello World, " + serviceName);
}
/* (non-Javadoc)
* @see com.easyway.apache.moduler.jmx.IEasywayService#printHello(java.lang.String)
*/
public void printHello(String whoName) {
System.out.println("Hello , " + serviceName);
}
}
　　2.针对JMX的MBean的描述符文件如下：

<?xml version="1.0"?>
<mbeans-descriptors>
<!--
对<mbean>标签做一下说明：
name mbean在xml中的唯一标识，不一定要和类同名
description　mbean的注释说明信息
domain mbean所属域
group mbean所属组
type mbean的类全名（包名＋类名）
classname 指定实现代理功能的ModelMbean的全名，如果不指定则默认为BaseModelMBean

备注：在这个文件中可以配置对各JMXbean对象
-->
<mbean name="EasywayService" description="the EasywayService bean" domain="easyway" group="helloGroup" type="com.easyway.apache.moduler.jmx.EasywayService">
<attribute name="serviceName" description="a name attribute" type="java.lang.String" writeable="true"/>
<operation name="printHello" description="a operation to print hello" impact="INFO" returnType="String"/>
</mbean>
</mbeans-descriptors>

　　3.针对JMX的Agent代理如下：

package com.easyway.apache.moduler.jmx;
import java.io.InputStream;
import javax.management.MBeanServer;
import javax.management.ObjectName;
import javax.management.modelmbean.ModelMBean;
import org.apache.commons.modeler.ManagedBean;
import org.apache.commons.modeler.Registry;
import com.sun.jdmk.comm.HtmlAdaptorServer;
/**
* JMX代理测试的应用
* @author longgangbai
*
*/
public class EasywayServiceBeanAgent {

public static void main(String[] args) throws Exception {
//基于xml中的信息构建一个Registry
Registry registry = Registry.getRegistry(null, null);
InputStream stream = EasywayServiceBeanAgent.class.getResourceAsStream("/Mbeans-descriptors.xml");
registry.loadMetadata(stream);
stream.close();

//由Registry得到一个MBeanServer
MBeanServer server = registry.getMBeanServer();
//得到Hello在描述文件中的信息类，对应于xml文件<mbean>标签的name属性。
ManagedBean managed = registry.findManagedBean("EasywayService");
//创建ObjectName
ObjectName helloName = new ObjectName(managed.getDomain() + ":name=EasywayService");
//得到ModelMBean 动态生成相应的方法的对应的XxxxMBean的接口
ModelMBean hello = managed.createMBean(new EasywayService());
//注册MBean
server.registerMBean(hello, helloName);
ObjectName adapterName = new ObjectName("EasywayServiceBeanAgent:name=htmladapter,port=8082");
HtmlAdaptorServer adapter = new HtmlAdaptorServer();
server.registerMBean(adapter, adapterName);
adapter.start();
System.out.println("start.....");
}
}
