如何从JMX Server获取Mbean

您好我正在尝试让Mbean已经在MbeanServer中注册并尝试调用方法并获取IllegalArgumentException：参数类型不匹配不确定原因。任何帮助将受到高度赞赏

MBeanServer mbs = ManagementFactory.getPlatformMBeanServer(); 
//ObjectName name = new ObjectName("org.ihc.perf.monitor:type=HelloWorld");
ObjectName name = new ObjectName(beanName);
if (mbs.isRegistered(name)) {
        PerfMonitorMBean mbean =
           (PerfMonitorMBean)MBeanServerInvocationHandler.newProxyInstance(
                mbs,name,PerfMonitorMBean.class,true);
        perfMonHash.put(beanName, mbean);
        return;
}
PerfMonitor mbean = new PerfMonitor();
//PerfMonitor mbean = new PerfMonitor();
mbs.registerMBean(mbean, name);
perfMonHash.put(beanName, mbean);
//isMBeanRegistered = true;

当我尝试使用

访问Mbean上的方法时 
perfMonHash.get(Constants.JMXMBEANNAME).addServiceData(serviceData);

我明白了：

我的Mbean实施是：

public class PerfMonitor extends NotificationBroadcasterSupport implements PerfMonitorMBean {

    private static final Logger logger = LoggerFactory.getLogger(PerfMonitor.class);
    private long sequenceNumber = 1;

    private ConcurrentHashMap<String, ServiceData> perfData=new ConcurrentHashMap<String, ServiceData>();



    public ConcurrentHashMap<String, ServiceData> getPerfData() {
        return perfData;
    }

    public void setPerfData(ConcurrentHashMap<String, ServiceData> perfData) {
        this.perfData = perfData;
    }

    public ServiceData getServiceData(String key){
    return perfData.get(key);
    }

    public void addServiceData(ServiceData serviceData){
    if(serviceData.getServiceName()!=null){
    String key=(serviceData.getServiceName()+"_"+serviceData.getRuntimeEnv()).toLowerCase().trim();
    logger.debug("Adding data for key:{}",key);
    perfData.put(key, serviceData);
    Notification n = new AttributeChangeNotification(this,
        sequenceNumber++, System.currentTimeMillis(),
        "ServiceData got added", "serviceData", "ServiceData",
        null, null);
    n.setUserData(serviceData);
    logger.debug("Sending Notification...");
    sendNotification(n);
    }
    }

//    private  ServiceData serviceData;
//
//    public ServiceData getServiceData() {
//  return serviceData;
//    }
//
//    public void setServiceData(ServiceData serviceData) {
//  this.serviceData=serviceData;
//  Notification n = new AttributeChangeNotification(this,
//      sequenceNumber++, System.currentTimeMillis(),
//      "ServiceData got added", "serviceData", "ServiceData",
//      null, null);
//  n.setUserData(serviceData);
//  sendNotification(n);
//    }

    //private static PerfMonitor mbean = new PerfMonitor();


    // private static boolean isMBeanRegistered = false;



    @Override
    public MBeanNotificationInfo[] getNotificationInfo() {
    String[] types = new String[]{
        AttributeChangeNotification.ATTRIBUTE_CHANGE
    };

    String name = AttributeChangeNotification.class.getName();
    String description = "An attribute of this MBean has changed";
    MBeanNotificationInfo info = 
        new MBeanNotificationInfo(types, name, description);
    return new MBeanNotificationInfo[]{info};
    }





}

ServiceData类：

import java.io.Serializable; import java.math.BigDecimal; 

public class ServiceData implements Serializable{

    /**
     * 
     */
    private static final long serialVersionUID = 1L;
    private String runtimeEnv;
    private String applicationID;
    private String serviceName; // ~ Endpoint
    private String userID;
    private String guid;
    private String requestPayload;
    private String responsePayload;
    private BigDecimal requestTime;
    private BigDecimal responseTime;

    public String getRuntimeEnv() {
        return runtimeEnv;
    }
    public void setRuntimeEnv(String runtimeEnv) {
        this.runtimeEnv = runtimeEnv;
    }
    public String getApplicationID() {
        return applicationID;
    }
    public void setApplicationID(String applicationID) {
        this.applicationID = applicationID;
    }
    public String getServiceName() {
        return serviceName;
    }
    public void setServiceName(String serviceName) {
        this.serviceName = serviceName;
    }
    public String getUserID() {
        return userID;
    }
    public void setUserID(String userID) {
        this.userID = userID;
    }
    public String getGuid() {
        return guid;
    }
    public void setGuid(String guid) {
        this.guid = guid;
    }
    public String getRequestPayload() {
        return requestPayload;
    }
    public void setRequestPayload(String requestPayload) {
        this.requestPayload = requestPayload;
    }
    public String getResponsePayload() {
        return responsePayload;
    }
    public void setResponsePayload(String responsePayload) {
        this.responsePayload = responsePayload;
    }
    public BigDecimal getRequestTime() {
        return requestTime;
    }
    public void setRequestTime(BigDecimal requestTime) {
        this.requestTime = requestTime;
    }
    public BigDecimal getResponseTime() {
        return responseTime;
    }
    public void setResponseTime(BigDecimal responseTime) {
        this.responseTime = responseTime;
    }

而不是使用：

if (mbs.isRegistered(name)) {
        PerfMonitorMBean mbean =
           (PerfMonitorMBean)MBeanServerInvocationHandler.newProxyInstance(
                mbs,name,PerfMonitorMBean.class,true);
        perfMonHash.put(beanName, mbean);
        return;
}

使用：

if (mbs.isRegistered(name)) {
        PerfMonitorMBean mbean =null;
        port=System.getProperty("com.sun.management.jmxremote.port");
            JMXServiceURL url =
                    new JMXServiceURL("service:jmx:rmi:///jndi/rmi://:"+port+"/jmxrmi");
                JMXConnector jmxc = JMXConnectorFactory.connect(url, null);
                MBeanServerConnection mbsc = jmxc.getMBeanServerConnection();
                mbean = JMX.newMBeanProxy(mbsc, name, PerfMonitorMBean.class, true);


        perfMonHash.put(beanName, mbean);

        return;

        }
