java - How can I know how many concurrent flows are currently active -


does spring-webflow provide way of getting know number of flows executing ?

i work around global bean, maybe webflow provides solution out-of-the-box.

edit: requested, here called "global bean" solution based on flowexecutionlisteneradapter

package your.package;  import org.apache.log4j.logger; import org.springframework.webflow.core.collection.attributemap; import org.springframework.webflow.definition.statedefinition; import org.springframework.webflow.definition.transitiondefinition; import org.springframework.webflow.execution.flowexecutionlisteneradapter; import org.springframework.webflow.execution.flowsession; import org.springframework.webflow.execution.requestcontext;  public class flowexecutionlistener extends flowexecutionlisteneradapter {      private static logger   logger          = logger.getlogger(flowexecutionlistener.class);     private int             sessioncount    = 0;       @override     public void sessionstarted(final requestcontext context, final flowsession session) {         super.sessionstarted(context, session);         sessioncount++;         logger.debug("sessionstarted, state: " + session.getstate().getid() + ", count: " + sessioncount);     }       @override     public void sessionended(final requestcontext context, final flowsession session, final string outcome, final attributemap output) {         super.sessionended(context, session, outcome, output);         sessioncount--;         logger.debug("sessionended, state: " + session.getstate().getid() + ", count: " + sessioncount);     }  }

the bean must registered @ spring-level:

<bean id="flowexecutionlistener" class="your.package.flowexecutionlistener" />

edit2:

if have more 1 webflow in application, count all active flows. in case want account them separately, can flow's id session.getdefinition().getid().
