正确退出activity_Activiti终止当前运行的流程实例

当启动一个流程实例且这个实例没有结束时，如何根据我们的业务id终止这流程实例呢？且看如下：

首先根据业务key获取到对应的流程实例，然后根据流程实例的id获取正在运行的任务，然后根据任务id和结束节点(type为endEvent)直接终止流程实例/**

* 终止正在运行的流程实例

* @author:kaka

* @param dkey:流程定义key,businessKey:业务id

*/

public void stopRunProcessInstance( String dkey,String businessKey) {

if( null != businessKey ) {

HistoricProcessInstance processInstanceId = workflowFactory.getHistoryService().createHistoricProcessInstanceQuery().processInstanceBusinessKey( businessKey ).singleResult();

Task task = workflowFactory.getTaskService().createTaskQuery().processInstanceId( processInstanceId.getId() ).singleResult();

if(null != task){

TaskServiceImpl taskServiceImpl = ( TaskServiceImpl )workflowFactory.getTaskService();

// 直接跳转到结束

String eventActivityId = workflowUtils.getEndEventActivityId(dkey);

taskServiceImpl.getCommandExecutor().execute( new JumpTaskCmdService( task.getExecutionId(), eventActivityId) );

}

}

}

workflowUtils.getEndEventActivityId(dkey)是我自己封装的一个获取结束节点activitiId的方法public String getEndEventActivityId(String dkey){

String endActivityId = null;

List allActivities = getAllActivities(dkey);

for(ActivityImpl activity : allActivities){

String type = activity.getProperty("type").toString();

if(type.equals("endEvent")){

endActivityId = activity.getId();

break;

}

}

return endActivityId;

}

//存放流程对应的所有activity

private static Map> processActivitiMap = new HashMap<>();

public List getAllActivities(String dkey) {

List activities = processActivitiMap.get(dkey);

if(activities == null){

RepositoryService repositoryService = factory.getRepositoryService();

ProcessDefinition definition = repositoryService.createProcessDefinitionQuery().processDefinitionKey(dkey).singleResult();

ProcessDefinitionEntity processDefinition = (ProcessDefinitionEntity) ((RepositoryServiceImpl) repositoryService)

.getDeployedProcessDefinition(definition.getId());

//获取所有的activity

activities = processDefinition.getActivities();

processActivitiMap.put(dkey,activities);

}

return activities;

}
