activiti7 获取流程图各节点信息

网上都是5或者6版本的 获取流程图节点，连线列表的信息。
我想知道用activiti7版本的怎么获取流程图各节点信息，
因为我想查出连线和节点信息去设置一些自定义的信息。

``` // 查询当前的流程实例
ProcessInstance processInstance = runtimeService.createProcessInstanceQuery().processInstanceId(processInstanceId).singleResult();
BpmnModel bpmnModel = repositoryService.getBpmnModel(processInstance.getProcessDefinitionId());
//获取当前流程的流程定义processDefinitionEntity，然后根据流程定义获得所有的节点
ProcessDefinitionEntity processDefinitionEntity = (ProcessDefinitionEntity) repositoryService.createProcessDefinitionQuery()
.processDefinitionId(processInstance.getProcessDefinitionId()).singleResult();

    processDefinitionEntity.getActivities()

最主要的是 processDefinitionEntity.getActivities() 再activiti7版本没有这个get方法了。就不知道怎么用了。求教各位大神，帮我研究下。

  /**
   * 获取流程节点
   *
   * @param definitionId 流程定义ID
   * @param processId 流程ID（可能为子流程），也就是流程定义Key
   * @return
   */
  protected List<FlowElement> getProcessDefinitionNodes(String definitionId, String processId) {
    BpmnModel bpmnModel = repositoryService.getBpmnModel(definitionId);

    List<Process> processes = Lists.newArrayList();

    if (StrUtil.isNotEmpty(processId)) {
      processes.add(bpmnModel.getProcessById(processId));
    } else {
      processes = bpmnModel.getProcesses();
    }

    List<FlowElement> flowElements = Lists.newArrayList();
    processes.forEach(process -> flowElements.addAll(process.getFlowElements()));

    return flowElements;
  }  

@GetMapping(value = "process/def/nodes/userTask")
  public AppResult getUserTaskNodes(
      @RequestParam(value = "id") String definitionId,
      @RequestParam(value = "processId", required = false) String processId) {

    List<FlowElement> flowElements = getProcessDefinitionNodes(definitionId, processId);
    List<UserTask> userTasks = Lists.newArrayList();
    flowElements.forEach(
        node -> {
          if (node instanceof UserTask) {
            userTasks.add((UserTask) node);
          }
        });

    return buildSuccess(userTasks);
  }

// 返回数据格式（节点）

正好看到了，你可以这样做
