连接服务器JMX，远程和本地代码不一致解决

远程： 

String jmxURL ="service:jmx:rmi:///jndi/rmi://192.168.10.93:8999/jmxrmi"; 
JMXServiceURL serviceURL = newJMXServiceURL(jmxURL);  
Map map = new HashMap();  
String[] credentials = new String[] { "monitorRole" , "QED"};  
map.put("jmx.remote.credentials",credentials);  
JMXConnector connector = JMXConnectorFactory.connect(serviceURL,map);  
MBeanServerConnection  mbsc =connector.getMBeanServerConnection();  
//堆使用率  
ObjectName heapObjName = newObjectName("java.lang:type=Memory");  
MemoryUsage heapMemoryUsage = MemoryUsage.from((CompositeDataSupport)mbsc.getAttribute(heapObjName,"HeapMemoryUsage"));  
long maxMemory =heapMemoryUsage.getMax();//堆最大  
long commitMemory =heapMemoryUsage.getCommitted();//堆当前分配  
long usedMemory =heapMemoryUsage.getUsed();              

本地： 
List<MBeanServer> mBeanServers =MBeanServerFactory.findMBeanServer(null); 
ClassLoadingMXBean classBean =ManagementFactory.getClassLoadingMXBean(); 
MemoryMXBean mxBean =ManagementFactory.getMemoryMXBean(); 
OperatingSystemMXBean osMBean =ManagementFactory.getOperatingSystemMXBean(); 
ThreadMXBean thrBean =ManagementFactory.getThreadMXBean(); 

即直接用 MBeanServerFactory获取MBean. 
若使用远程一样的方法，用localhost连接jmx再包装发布在jmx中，会连不上
