JMX 注册MBean服务 MBean RMI

 

JMX 注册MBean服务 MBean RMI

X的概念不说了，可以管理很多组件，例子程序用了简单的bean，然后JMX注册它进行管理，JMX可以管理其他高级组件，管理osgi等等。jmx可以通过http，rmi等方式管理组件，jmx配上osgi来管理组件就很好了，osgi。。。

try {
            String DOMAIN = "localhost";
            // 创建一个MBeanServer

            MBeanServer server = MBeanServerFactory.createMBeanServer(DOMAIN);
            // 用MBeanServer注册LoginStatsMBean
            // MBeanServer.registerMBean(Object，ObjectName)方法使用的参数有两个：一个是MBean实现的一个实例；另一个是类型ObjectName的一个对象-它用于唯一地标识该MBean
            server.registerMBean(new Status(), new ObjectName(DOMAIN + ":name=statusBean"));
            // 存取该JMX服务的URL：
            JMXServiceURL url = new JMXServiceURL("rmi", "127.0.0.1", 9589, "/jndi/rmi://localhost:" + 1099 + "/linpeiwen");
            // start()和stop()来启动和停止 JMXConnectorServer
            JMXConnectorServer jmxServer = JMXConnectorServerFactory.newJMXConnectorServer(url, null, server);

            System.out.println(url);
            // 在RMI上注册
            LocateRegistry.createRegistry(1099);

            jmxServer.start();

        } catch (Exception e) {
            e.printStackTrace();
        }

通过JConsole便可以访问这个MBEAN里面的public方法：

 

在JMX URL中输入jmx service url: service:jmx:rmi:///jndi/rmi://localhost:1099/linpeiwen

就可以访问到注册到的MBean中的方法.

 

例子程序：

//SimpleStandardMBean.java 简单的被管理的bean

public interface SimpleStandardMBean {

public void setName(String name);

public String getName(String name);

public void reSet();

public int getAge();
}

//SimpleStandard.java 简单的被管理的bean的实现

public class SimpleStandard implements SimpleStandardMBean{

public String name;
public int getAge() {
   return 24;
}

public String getName(String name) {
   this.name=name;
   System.out.println("----------调用了getName方法----------");
   return this.name;
}

public void reSet() {
   System.out.println("----------reSet()-----------");
}

public void setName(String name) {
   this.name=name;  
}

public void aaa(){
   System.out.println("888888888888888888888");
}

}
