Activiti5 常用方法

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();  
      
    oricProcessInstance 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);
