监控Coherence成员的加入和离开集群事件

对server事件的监控主要是实现MemberListener类，对Cache事件的监控主要通过MapListener

参考代码

package coherencetest;

import com.tangosol.net.CacheFactory;
import com.tangosol.net.MemberEvent;
import com.tangosol.net.MemberListener;
import com.tangosol.net.NamedCache;
import com.tangosol.util.MapEvent;
import com.tangosol.util.MapListener;

 

class ProxyListenerNotification implements MemberListener {
public void memberJoined (MemberEvent e) {
System.out.println("====== Member Join ");
}
public void memberLeaving(MemberEvent e) {}
public void memberLeft(MemberEvent e) {
System.out.println("************ Member Left");

 System.out.println(e.getMember());
//NamedCache cache = CacheFactory.getCache("POFSample");
//cache.size(); // force reconnection to another proxy server
}
}

public class ProxyListener {

public static void main(String[] args) {
try {
NamedCache cache = CacheFactory.getCache("POFSample");
/*
cache.addMapListener(new MapListener() {

public void entryUpdated(MapEvent arg0) {
System.out.println(arg0);
}

public void entryInserted(MapEvent arg0) {
System.out.println(arg0);

}
public void entryDeleted(MapEvent arg0) {
System.out.println(arg0);
}});
*/
cache.getCacheService().addMemberListener(new ProxyListenerNotification());

while(true){
// Thread.sleep(100000);
}
} catch (Exception e) {
System.out.println(e);
}
}
}

 

当proxy server或storage server加入或者离开集群时，输出如下：

 

TcpRing{Connections=[3]}
IpMonitor{Addresses=0, Timeout=15s}
