获取 mbean 属性值？

Question

我被困在这里：

我需要获取以下值

org.jboss.system.server.ServerInfo

通过这里的代码，我正在读取 mbean 属性，但我只能找到 .hashvalues！

final MBeanAttributeInfo[] attributes = server.getMBeanInfo(mbean).getAttributes();
for (final MBeanAttributeInfo attribute : attributes) {
                    String name = attribute.getName();                            
}

经过两天的搜索，我请求帮助！

非常感谢，罗曼。

public static Map<String, Object> getAllAttributes(String host, int port, String mbeanName) throws MalformedObjectNameException, IOException, InstanceNotFoundException, IntrospectionException, ReflectionException, AttributeNotFoundException, MBeanException {
    // Get JMX connector and get MBean server connection
    JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://" + host + ":" + port + "/jmxrmi");
    JMXConnector jmxc = JMXConnectorFactory.connect(url, null);
    MBeanServerConnection mbsc = jmxc.getMBeanServerConnection();       

    // Query all attributes and values
    ObjectName name = new ObjectName(mbeanName);
    MBeanInfo info = mbsc.getMBeanInfo(name);
    MBeanAttributeInfo[] attrInfo = info.getAttributes();
    Map<String, Object> map = new HashMap<>();
    for (MBeanAttributeInfo attr : attrInfo) {
        if (attr.isReadable()) {
            //System.out.println("\t" + attr.getName() + " = " + mbsc.getAttribute(name, attr.getName()));
            map.put(attr.getName(), mbsc.getAttribute(name, attr.getName()));
            }
        }
    jmxc.close();
    return map;

}
