https://blogs.oracle.com/jmxetc/entry/tracing_jmx_what_s_going な感じらしい。ちょっとデモっぽいのやってみた

MBean.java

package sample;

public interface MBean {

    public static final String SERVICE = "service:jmx:rmi:///jndi/rmi://localhost/sample";

    public static final String OBJECT_NAME = "sample.jmx:Type=JmxServer";

    public void test();

}

MBeanImpl.java

package sample;

import javax.management.StandardMBean;

public class MBeanImpl extends StandardMBean implements MBean {
    public MBeanImpl() {
        super(MBean.class, false);
    }
    public void test() {
        System.out.println("hoge fuga foobar");
    }
}

Server.java

package sample;

import java.rmi.registry.LocateRegistry;
import javax.management.MBeanServer;
import javax.management.ObjectName;
import javax.management.remote.JMXServiceURL;
import javax.management.remote.JMXConnectorServer;
import javax.management.remote.JMXConnectorServerFactory;
import java.lang.management.ManagementFactory;

public class Server {
    public static void main(String[] args) throws Exception {
        LocateRegistry.createRegistry(1099);

        MBeanServer mbean = ManagementFactory.getPlatformMBeanServer();
        mbean.registerMBean(new MBeanImpl(), new ObjectName(MBean.OBJECT_NAME));

        JMXServiceURL url = new JMXServiceURL(MBean.SERVICE);
        JMXConnectorServer server = JMXConnectorServerFactory.newJMXConnectorServer(url, null, mbean);
        server.start();
    }
}

な感じで作って、logging.propertiesを作る

handlers= java.util.logging.ConsoleHandler
.level=INFO

java.util.logging.ConsoleHandler.level = FINEST
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter

javax.management.level=FINEST
javax.management.remote.level=FINER

あとは普通にServerクラスを実行して、jconsoleとかで接続してぐだぐだしてみると今回はConsoleHandlerなのでサーバー実行コンソール上に出る。FileHandlerとか使えば(ry

Client.java

jconsoleじゃなくて、クライアント作って試しても良い

package sample;

import javax.management.remote.JMXServiceURL;
import javax.management.remote.JMXConnector;
import javax.management.remote.JMXConnectorFactory;
import javax.management.MBeanServerConnection;
import javax.management.ObjectName;

public class Client {
    public static void main(String[] args) throws Exception {
        JMXServiceURL url = new JMXServiceURL(MBean.SERVICE);
        JMXConnector connector = JMXConnectorFactory.connect(url);
        MBeanServerConnection conn = connector.getMBeanServerConnection();
        ObjectName oname = new ObjectName(MBean.OBJECT_NAME);

        conn.invoke(oname, "test", null, null);
    }
}
