camunda 驳回一

前言

camunda 7.18 驳回操作

---

一、代码

//查找历史结束user task节点
					List<HistoricActivityInstance> historicActivityInstances = historyService
							.createHistoricActivityInstanceQuery().activityType("userTask")
							.processInstanceId(task.getProcessInstanceId())
							.finished()
							.orderByHistoricActivityInstanceEndTime().asc().list();

					if (historicActivityInstances != null && historicActivityInstances.size()>0){
						//获取上一节点信息
						HistoricActivityInstance activity=new HistoricActivityInstanceEntity();
						boolean flag = true;
						for (int i=0;i<historicActivityInstances.size();i++){
							if(historicActivityInstances.get(i).getActivityId().equals(task.getTaskDefinitionKey())){
								if (i-1<0){
									//第一用户节点，不可驳回
									throw new DataInvalidException("REJECT_FAIL","Rejection failure");
								}else {
									activity=historicActivityInstances.get(i-1);
								}
								flag=false;
								break;
							}
						}
						if (flag){
							activity=historicActivityInstances.get(historicActivityInstances.size()-1);
						}
						identityService.setAuthenticatedUserId(assignee);
						taskService.createComment(taskId,task.getProcessInstanceId(),comment);
						
						runtimeService.createProcessInstanceModification(task.getProcessInstanceId())
								.cancelAllForActivity(task.getTaskDefinitionKey())
								.startBeforeActivity(activity.getActivityId())
								.setAnnotation(taskId)
								.execute();

					}else {
						System.out.println("第一用户节点，驳回失败");
					}

缺陷

只能用于简单串行流程
