flowable中 获取流程中任务节点的方法有好几种

1.这种是常见的一种

获取流程  正在激活 中任务节点

List<HistoricActivityInstance> historicActivityInstanceList =  historyService.createHistoricActivityInstanceQuery()
            .processInstanceId(procInsId)
            .activityTypes(CollUtil.newHashSet(BpmnXMLConstants.ELEMENT_EVENT_START, BpmnXMLConstants.ELEMENT_EVENT_END, BpmnXMLConstants.ELEMENT_TASK_USER))
            .orderByHistoricActivityInstanceStartTime().desc()
            .orderByHistoricActivityInstanceEndTime().desc()
            .list();

// 构建查询条件
        HistoricActivityInstanceQuery query = historyService.createHistoricActivityInstanceQuery()
            .processInstanceId(procInsId);
        List<HistoricActivityInstance> allActivityInstanceList = query.list();

一般是 未完成审核流程 所处当前节点 之前所有节点及 下一个节点

2.获取流程  所有 任务节点

List<HistoricActivityInstance> historicActivityInstanceList =  historyService.createHistoricActivityInstanceQuery()
            .processInstanceId(procInsId)
            .orderByHistoricActivityInstanceStartTime().desc()
            .orderByHistoricActivityInstanceEndTime().desc()
            .list();

        HistoricProcessInstance historicProcIns = historyService.createHistoricProcessInstanceQuery()
            .processInstanceId(procInsId)
            .includeProcessVariables()
            .singleResult();

        // 获取Bpmn模型信息
        InputStream inputStream = repositoryService.getProcessModel(historicProcIns.getProcessDefinitionId());
        String bpmnXmlStr = StrUtil.utf8Str(IoUtil.readBytes(inputStream, false));
        BpmnModel bpmnModel = ModelUtils.getBpmnModel(bpmnXmlStr);
        System.out.println(bpmnModel);
//        Activity_02nvulp

//        bpmnModel.getProcesses().get(0).getFlowElements().forEach(item -> System.out.println(item.getName()));
        if(ObjectUtil.isNotEmpty(taskId)){
            // 获取当前节点
//            String currentTaskId = taskId;
            // 获取当前节点的连线
            List<SequenceFlow> outgoingFlows = ModelUtils.getElementOutgoingFlows(ModelUtils.getFlowElementById(bpmnModel, taskId));

事实上就是解析流程 bpmn xml文件 获取到所有节点
