产生原因:创建子流程时,businesskey 不传递。
解决如下:
1、创建监听类:
import org.activiti.engine.delegate.event.ActivitiEntityEvent; import org.activiti.engine.delegate.event.ActivitiEvent; import org.activiti.engine.delegate.event.ActivitiEventListener; import org.activiti.engine.impl.persistence.entity.ExecutionEntity; import org.activiti.engine.impl.persistence.entity.TaskEntity; import org.apache.commons.lang3.StringUtils; import org.slf4j.Logger; import org.slf4j.LoggerFactory; public class BusinessKeyInjectionActivitiEventListener implements ActivitiEventListener { private Logger log = LoggerFactory.getLogger(getClass()); @Override public void onEvent(ActivitiEvent event) { switch (event.getType()) { case TASK_CREATED: if (event instanceof ActivitiEntityEvent) { ActivitiEntityEvent activityEntityEvent = (ActivitiEntityEvent) event; TaskEntity taskEntity = (TaskEntity) activityEntityEvent.getEntity(); ExecutionEntity exEntity = taskEntity.getExecution(); String key = exEntity.getBusinessKey(); log.info("获取当前任务的流程实例的businessKey:{}",key); if(StringUtils.isEmpty(key)){ ExecutionEntity superExecEntity = exEntity.getSuperExecution(); key=superExecEntity.getBusinessKey(); if(StringUtils.isEmpty(key)){ key=superExecEntity.getProcessInstance().getBusinessKey(); } log.info("获取当前任务 上一个流程实例的businessKey:{}",key); log.info("设置当前流程实例的businessKey:{}",key); exEntity.setBusinessKey(key); //让businessKey生效 此处非常关键。 exEntity.updateProcessBusinessKey(key); } break; } default: break; } } @Override public boolean isFailOnException() { // TODO Auto-generated method stub return false; } }
