在我的weblogic服务器中部署了ehcache,我需要通过java编程从这个程序中获取ehcahe mbean,通过JMX我无法连接。我怎样才能获得那些自定义mbean?
我尝试通过 weblogic t3 协议(protocol)获取 mbean
public class Test
{
private String hostName = "";
private String port = "";
private String userName = "";
private String password = "";
private String connectorURL = "service:jmx:rmi:///jndi/rmi://{0}:{1}/jmxrmi";
private JMXConnector jmxc = null;
public static void main(String []args) throws Exception
{
Test t = new Test();
t.hostName = args[0];
System.out.println(args[1]);
t.port = args[1];
t.userName = args[2];
t.password = args[3];
t.jmxc = t.initConnection();
MBeanServerConnection mbsc = t.jmxc.getMBeanServerConnection();
System.out.println(mbsc);
Set<ObjectInstance> st =mbsc.queryMBeans(new ObjectName("net.*:*"), null);
System.out.println(st.toString());
Iterator<ObjectInstance> it = st.iterator();
while(it.hasNext())
{
System.out.println(it.next());
}
t.closeConnection();
}
private JMXConnector initConnection()
{
System.out.println("initiate connection");
JMXServiceURL serviceURL = null;
try
{
String jndiroot = "/jndi/";
String mserver = "weblogic.management.mbeanservers.domainruntime";
int port1 = Integer.parseInt(port);
serviceURL = new JMXServiceURL("t3", hostName, port1, 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");
long lngJmxClientWTO = 10000;
h.put("jmx.remote.x.request.waiting.timeout", lngJmxClientWTO );
return JMXConnectorFactory.connect(serviceURL, h);
}
catch (Exception e)
{
e.printStackTrace();
return null;
}
}
/**
* This method closes client connection with server
* @throws IOException
*/
public void closeConnection()
{
if(jmxc != null)
{
try
{
jmxc.close();
}
catch (IOException e) {
jmxc = null;
}
}
}
最佳答案
import net.sf.ehcache.CacheManager;
import net.sf.ehcache.Ehcache;
CacheManager manager = CacheManager.newInstance();
Ehcache cache = manager.getEhcache("Some cache name here..."); //<-- PLEASE EDIT THE CACHE NAME...
不知道你要的是不是这个......
一旦获得缓存
,您就可以使用它,就像java map
一样。
您可以关注Ehcache documentation了解如何以编程方式获取远程缓存。本质上,您需要创建一个 configuration (or configuration file) CacheManager
可以访问它。
