Java 使用MBeanServerConnection获取服务器名称和状态

我正在尝试使用MBeanServerConnection获取域中服务器的名称和状态

public class GetServerState {

   private static MBeanServerConnection connection;
   private static JMXConnector connector;
   private static final ObjectName service;

   // Initializing the object name for DomainRuntimeServiceMBean
   // so it can be used throughout the class.
   static {
      try {
         service = new ObjectName(
            "com.bea:Name=DomainRuntimeService,Type=weblogic.management.
             mbeanservers.domainruntime.DomainRuntimeServiceMBean");
      }catch (MalformedObjectNameException e) {
         throw new AssertionError(e.getMessage());
      }
   }

   /*
   * Initialize connection to the Domain Runtime MBean Server
   */
   public static void initConnection(String hostname, String portString, 
      String username, String password) throws IOException,
      MalformedURLException { 
      String protocol = "t3";
      Integer portInteger = Integer.valueOf(portString);
      int port = portInteger.intValue();
      String jndiroot = "/jndi/";
      String mserver = "weblogic.management.mbeanservers.domainruntime";
      JMXServiceURL serviceURL = new JMXServiceURL(protocol, hostname,
         port, jndiroot + mserver);
      Hashtable h = new Hashtable();
      h.put(Context.SECURITY_PRINCIPAL, username);
      h.put(Context.SECURITY_CREDENTIALS, password);
      h.put(JMXConnectorFactory.PROTOCOL_PROVIDER_PACKAGES,
         "weblogic.management.remote");
      connector = JMXConnectorFactory.connect(serviceURL, h);
      connection = connector.getMBeanServerConnection();
   }

   /* 
   * Print an array of ServerRuntimeMBeans.
   * This MBean is the root of the runtime MBean hierarchy, and
   * each server in the domain hosts its own instance.
   */
   public static ObjectName[] getServerRuntimes() throws Exception {
      return (ObjectName[]) connection.getAttribute(service,
         "ServerRuntimes");
   }

   /* 
   * Iterate through ServerRuntimeMBeans and get the name and state
   */
   public void printNameAndState() throws Exception {
      ObjectName[] serverRT = getServerRuntimes();
      System.out.println("got server runtimes");
      int length = (int) serverRT.length;
      for (int i = 0; i < length; i++) {
         String name = (String) connection.getAttribute(serverRT[i],
            "Name");
         String state = (String) connection.getAttribute(serverRT[i],
            "State");
         System.out.println("Server name: " + name + ".   Server state: "
            + state);
      }
   }

   public static void main(String[] args) throws Exception {
      String hostname = args[0];
      String portString = args[1];
      String username = args[2];
      String password = args[3];

      GetServerState s = new GetServerState();
      initConnection(hostname, portString, username, password);
      s.printNameAndState();
      connector.close();
   }
}

在这里，我得到的只是那些处于运行状态的服务器的名称，而不是域中所有服务器的列表。

有人能告诉我需要做哪些更改才能获取域中所有服务器的名称和状态吗？

因为服务器已关闭，可能没有服务器运行时实例。。。如果你愿意，你可以在这里试试这个例子：谢谢！这个解决方案进行了一些修改！好-如果您愿意，您可以将相关代码作为答案发布，并将其标记为已接受
