如何使用JMX API获取ObjectName的子级

// 获取本地 MBeanServer 的连接
MBeanServer mbs = ManagementFactory.getPlatformMBeanServer();

// 对于远程连接，使用JMXConnector
JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://host:port/jmxrmi");
JMXConnector jmxc = JMXConnectorFactory.connect(url, null);
MBeanServerConnection mbsc = jmxc.getMBeanServerConnection();

// 创建一个带有通配符的 ObjectName
ObjectName queryName = new ObjectName("com.example.myapp:type=MyType,*");

// 查询 MBeans
Set<ObjectInstance> instances = mbs.queryMBeans(queryName, null);
for (ObjectInstance instance : instances) {
    System.out.println("Found MBean: " + instance.getObjectName());
}

import javax.management.*;
import java.lang.management.ManagementFactory;
import java.util.Set;

public class JMXExample {
    public static void main(String[] args) throws Exception {
        MBeanServer mbs = ManagementFactory.getPlatformMBeanServer();
        ObjectName queryName = new ObjectName("com.example.myapp:type=MyType,*");

        Set<ObjectInstance> instances = mbs.queryMBeans(queryName, null);
        for (ObjectInstance instance : instances) {
            System.out.println("Found MBean: " + instance.getObjectName());
        }
    }
}
