activiti&flowable擷取下一個節點資訊

直接貼代碼，不懂可說明：

/**
 * 擷取下一個節點的資訊測試
 */
@Test
public void testNextTasks() {

    //流程執行個體id
    String processInstanceId = "5b945750-81db-11e9-a576-1a73f8e23adc";

    //目前任務資訊
    Task task = taskService.createTaskQuery().processInstanceId(processInstanceId).singleResult();

    //擷取流程釋出Id資訊
    String definitionId = runtimeService.createProcessInstanceQuery().processInstanceId(processInstanceId).singleResult().getProcessDefinitionId();

    //擷取bpm對象
    BpmnModel bpmnModel = repositoryService.getBpmnModel(definitionId);

    //傳節點定義key 擷取目前節點
    FlowNode flowNode = (FlowNode) bpmnModel.getFlowElement(task.getTaskDefinitionKey());

    //輸出連線
    List<SequenceFlow> outgoingFlows = flowNode.getOutgoingFlows();

    //周遊傳回下一個節點資訊
    for (SequenceFlow outgoingFlow : outgoingFlows) {
        //類型自己判斷
        FlowElement targetFlowElement = outgoingFlow.getTargetFlowElement();
        //使用者任務
        if (targetFlowElement instanceof UserTask) {
            //。。。
        }
        else if (targetFlowElement instanceof ExclusiveGateway) {
            setExclusiveGateway(targetFlowElement);
        }
    }
}


private void setExclusiveGateway(FlowElement targetFlow) {
        //排他網關，擷取連線資訊

        for (SequenceFlow sequenceFlow : targetFlows) {
            //目标節點資訊
