Purpose
This article describes how to fetch Process Instance and Activity Instance related Historical Events like Time, Type and Details..etc, based on the defined Historical Event Policy.
Activity Instance Historical Events:
ProcessInstanceFilter filter = new ProcessInstanceFilter(piOID); //Pass in the Process instance OID ActivityInstanceQuery query = new ActivityInstanceQuery(); query.where(filter); query.setPolicy(HistoricalEventPolicy.ALL_EVENTS); query.orderBy(ActivityInstanceQuery.START_TIME); ActivityInstances actInstList = qs.getAllActivityInstances(query); for(ActivityInstance actInst: actInstList){ ActivityInstanceHistory actHistory = new ActivityInstanceHistory(actInst.getOID(), actInst.getActivity().getId(), actInst.getHistoricalEvents()); }
Process Instance Historical Events:
ProcessInstanceQuery piQuery = ProcessInstanceQuery.findAlive(); piQuery.setPolicy(HistoricalEventPolicy.ALL_EVENTS); ProcessInstances pis = qs.getAllProcessInstances(piQuery); for (Iterator iterator = pis.iterator(); iterator.hasNext();) { ProcessInstance pi = (ProcessInstance) iterator.next(); //log.info("PI: " + pi.getOID()); ProcessInstanceDetails details = (ProcessInstanceDetails)pi; List<HistoricalEvent> events = details.getHistoricalEvents(); for (HistoricalEvent historicalEvent : events) { System.out.println("PI:" + pi.getOID() + " Event time:" + historicalEvent.getEventTime()); System.out.println("PI:" + pi.getOID() + " Event type:" + historicalEvent.getEventType()); System.out.println("PI:" + pi.getOID() + " Event details :" + historicalEvent.getDetails()); } }
