activiti笔记

任务委托:
签收了的:
taskService.delegateTask(taskId, userId);

未签收的:
taskService.addCandidateUser(taskId, userId);


有一个节点的Id怎么得到这个节点的Activity:
processDefinitionEntity.findExctivity(activitiyId)


获得当前任务的所有节点:
		ProcessDefinitionEntity processDefinition1 = (ProcessDefinitionEntity) ((RepositoryServiceImpl) repositoryService)
				.getDeployedProcessDefinition(processInstance.getProcessDefinitionId());
		List<ActivityImpl> activitiList = processDefinition1.getActivities();//获得当前任务的所有节点


获取历史节点信息:
     List<HistoricActivityInstance>  hiaciList = getHistoryService().createHistoricActivityInstanceQuery().processInstanceId(processInstanceId).finished().orderByHistoricActivityInstanceEndTime().asc().list();

 HistoricProcessInstance historicProcessInstance =	historyService.createHistoricProcessInstanceQuery().processInstanceId(processInstanceId).singleResult();
       lastActivitiHandleUserName=historicProcessInstance.getStartUserId();


获取activiti变量:
第一种:
 	Map<String, Object> variables1 = runtimeService.getVariables("processInstanceId");

第二种:
List<HistoricVariableInstance> list = historyService.createHistoricVariableInstanceQuery().processInstanceId("6310").list();
		for (HistoricVariableInstance variableInstance : list) {
		  System.out.println("variable: " + variableInstance.getVariableName() + " = " + variableInstance.getValue());
		}


获取当前任务,通过processinstanceId:
		Task task11=	taskService.createTaskQuery().processInstanceId(processinstanceId).singleResult();


通过表达式分配任务:


变量通过map传递


删除流程:
流程没有结束: runtimeService.deleteProcessInstance(processInstanceId,"");
               historyService.deleteHistoricProcessInstance(procesInstanceId);(顺序不能换)
流程已经结束:historyService.deleteHistoricProcessInstance(procesInstanceId);
