[英]How to access ehcache mbeans on weblogic server
在我的weblogic服务器中,部署了ehcache,我需要通过java编程从该程序中获取ehcahe mbeans。通过JMX,我无法连接。如何获得这些自定义mbeans?
我试图通过weblogic t3协议获取mbeans
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;
}
}
}
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...
我不知道这是否是您要的...。
获取cache
,就可以使用它了,就像Java Map
。
您可以遵循Ehcache文档,以了解如何以编程方式获取远程缓存。 本质上,您将需要创建CacheManager
可以访问的配置(或配置文件) 。
