Java JMX MBeanServer

功能

MBeanServer可以获取Java服务的运行时的虚拟机信息。

代码

public class MBeanServerTest {

    public static void main(String[] args) {
        MBeanServer mBeanServer = ManagementFactory.getPlatformMBeanServer();
        try {
            Set<ObjectInstance> objectInstances = mBeanServer.queryMBeans(ObjectName.WILDCARD, null);
            for (ObjectInstance objectInstance : objectInstances) {
                System.out.println("ObjectInstance: " + objectInstance.getObjectName() + "---" + objectInstance.getClassName());
            }

            System.out.println("----------");

            Set<ObjectName> objectNames = mBeanServer.queryNames(ObjectName.WILDCARD, null);
            for (ObjectName objectName : objectNames) {
                System.out.println("ObjectName: " + objectName.getCanonicalName() + "---" + objectName.getKeyPropertyListString() + "---" + objectName.getDomain() + "---" + objectName.getKeyProperty("type") + "---" + objectName.getKeyProperty("name"));
            }
        } catch (Exception e) {
            System.out.println(e.getMessage());
        }
    }

}
