Flowable钉钉对接005-完成钉钉任务

企业中有自己的业务系统，审批都在业务系统中审批，如何结合移动办公的开放平台实现统一审批至关重要。

场景很简单，自己的系统中可以审批，钉钉上也可以审批，使用H5来适配，统一待办任务

目标：任务完成钉钉任务变成已完成任务

实现flowable钉钉相互之间可以创建待办，更新待办，删除待办

• 第一 、全局任务完成监听发送完成任务消息

flowMessageService.completeTaskToMq(entity, entity.getAssignee());

• 第二 、完成任务的消息接口

public boolean sendTaskMessage(ProcessInstance processInstance, TaskEntity entity, OperationTypeEnum operationType) {
        boolean flag = false;
        PlatformDingtalkTaskVo platformTask = new PlatformDingtalkTaskVo();
        platformTask.setOperationType(operationType.getCode());
        platformTask.setBussinessKey(processInstance.getBusinessKey());
        platformTask.setFlowableProInstId(processInstance.getProcessInstanceId());
        platformTask.setSubject(processInstance.getName());
        if (entity != null) {
            platformTask.setFlowableTaskId(entity.getId());
            ApplyerVo applyerVo = prodFlowTaskService.getApplyerVoByTaskId(entity.getId());
            if (applyerVo != null) {
                List<String> thirdUnionIds = new ArrayList<>();
                if (applyerVo.getApplyer() != null) {
                    thirdUnionIds.add(applyerVo.getApplyer().getThirdUnionId());
                    platformTask.setUnionId(applyerVo.getApplyer().getThirdUnionId());
                    platformTask.setCreatorId(applyerVo.getApplyer().getThirdUnionId());
                    platformTask.setOperatorId(applyerVo.getApplyer().getThirdUnionId());
                    platformTask.setMobile(applyerVo.getApplyer().getMobile());
                    flag = true;
                }
                if (CollectionUtils.isNotEmpty(applyerVo.getExecutors())) {
                    applyerVo.getExecutors().forEach(personal -> thirdUnionIds.add(personal.getThirdUnionId()));
                    flag = true;
                }
                platformTask.setExecutorIds(thirdUnionIds);
                platformTask.setFlowableTaskName(entity.getName());
                platformTask.setDingNotify("1");
                platformTask.setPriority(20);
                platformTask.setDueTime(DateUtil.addDate(new Date(), 1).getTime());
                platformTask.setIsOnlyShowExecutor(true);
                platformTask.setAppSn(processInstance.getTenantId());
                String url = "/process/operate?modelKey=" + processInstance.getProcessDefinitionKey()
                        + "&taskId=" + StringUtils.defaultIfEmpty(entity.getId(), "") + "&procInstId=" +
                        processInstance.getProcessInstanceId() + "&bizKey=" + processInstance.getBusinessKey();
                platformTask.setAppUrl(url);
                platformTask.setPcUrl(url);
                String json = JSON.toJSONString(platformTask);
                try {
                    if (!flag) {
                        log.error("未查询到审批的人信息，请确认！参数：" + json);
                    } else {

                        if (prodAppService.checkPlatformEnabled(processInstance.getTenantId())) {
                            this.convertAndSend(ProdflowConstant.FLOWABLE_TASK_MESSAGE_QUEUE, json);
                        }
                    }
                } catch (Exception e) {
                    e.printStackTrace();
                    log.error("推送到MQ异常！原因：" + e.getMessage());
                }
            }
        }
        return flag;
    }

• 第三 、接受mq消息处理

 HistoricTaskInstance historicTaskInstance = historyService.createHistoricTaskInstanceQuery().taskId(params.getFlowableTaskId()).singleResult();
                    List<HistoricTaskInstance> historictaskInstances = historyService.createHistoricTaskInstanceQuery().taskDefinitionKey(historicTaskInstance.getTaskDefinitionKey()).list();
                    if (CollectionUtils.isNotEmpty(historictaskInstances) && historictaskInstances.size() > 1) {
                        historictaskInstances.remove(historicTaskInstance);
                        historictaskInstances.forEach(hisTask -> {
                            if (ObjectUtil.isNotEmpty(hisTask.getEndTime())) {
                                PlatformDingtalkTask flowableTask = platformDingtalkTaskService.getByFlowableTaskId(hisTask.getId());
                                Boolean done = flowableTask.getDone();
                                if (!done) {
                                    //删除第三方的任务操作
                                    dingtalkSdkService.deleteTask(flowableTask.getUnionId(), flowableTask.getTaskId());
                                }
                            }
                        });
                    }
                    PlatformDingtalkTask updateTask = platformDingtalkTaskService.getByFlowableTaskId(params.getFlowableTaskId());
                    UpdateTodoTaskRequest updateTodoTaskRequest = this.updateDingtalkTask(params);
                    if (StringUtils.isNotBlank(updateTask.getExecutorIds())) {
                        updateTodoTaskRequest.setExecutorIds(FastJsonUtils.jsonToList(updateTask.getExecutorIds(), String.class));
                    }
                    updateTodoTaskRequest.setDone(true);
                    dingtalkSdkService.updateTask(params.getUnionId(), updateTask.getTaskId(), updateTodoTaskRequest);
                    updateTask.setDone(true);
                    platformDingtalkTaskService.updateById(updateTask);

• 总结、这样子就能完成钉钉消息和flowable之间的任务同步了
