Activiti获得下一个节点

用PvmTransition表示箭头的类。而这些类是从

List<PvmTransition> list = ActivityImpl.getOutgoingTransitions() ;

从任务id获得指向外面的连接线

ProcessDefinitionEntity.getActivities()

Task currentTask = (Task) taskService.createTaskQuery().taskId(taskId).singleResult();

/** *  *@User :Test *@date :2014-6-26 下午02:45:34 *@return :Execution  *@userFor :获得执行节点 ExecutionEntity.getActivityId() 获得节点id     *currentTask.getExecutionId() */  private ExecutionEntity getExecution(String executionId) {ExecutionEntity execution = (ExecutionEntity) (Execution) runtimeService.createExecutionQuery().executionId(executionId).singleResult();return execution;}

/** *  *@User   :Test *@date   :2014-6-26 下午02:38:39 *@return :ActivityImpl *@userFor :根据flowId获得下一个节点 ExecutionEntity.getActivityId() */private ActivityImpl getNextTask(ProcessDefinitionEntity processDefinition,String activitiId, String flowId) {ActivityImpl result = null;boolean breakFlag = false;List activitiList = processDefinition.getActivities();for (Iterator iterator = activitiList.iterator(); iterator.hasNext();) {ActivityImpl activityImpl = (ActivityImpl) iterator.next();if (breakFlag)break;String id = activityImpl.getId();if (activitiId.equals(id)) {List outTransitions = activityImpl.getOutgoingTransitions();for (Iterator iterator1 = outTransitions.iterator(); iterator1.hasNext();) {PvmTransition pvm = (PvmTransition) iterator1.next();if (flowId.length() > 0 && pvm.getId().equals(flowId)) {result = (ActivityImpl) pvm.getDestination();breakFlag = true;break;}}}}return result;}

从一个节点转向另一个节点最后还是得需要执行taskService.complete(taskId,varies);

// 获取当前节点的所以出口（这个方法做的不好，应该返回List<TransitionImpl>才对的，这样就不用下面的强转换了，我想以后版本会改了这点）List<PvmTransition> pvmTransitionList = activeActivity.getOutgoingTransitions();for (PvmTransition pvmTransition : pvmTransitionList) {TransitionImpl transitionImpl = (TransitionImpl) pvmTransition;// 强转为TransitionImpltransitionImpl.setDestination(endActivity);}        //最后还是得需要执行complete方法taskService.complete(taskId);
