作为系统流程维护，所有任务就比较有好处，以便对一些特殊任务或流程做一些特殊处理

1、后端增加所有任务列表包括导出，代码如下：

java 复制代码

	@Override
	public TableDataInfo<WfTaskVo> selectPageAllProcessList(ProcessQuery processQuery, PageQuery pageQuery) {
		Page<WfTaskVo> page = new Page<>();
        HistoricProcessInstanceQuery historicProcessInstanceQuery = historyService.createHistoricProcessInstanceQuery()
        	.includeProcessVariables()
            .orderByProcessInstanceStartTime()
            .desc();
        // 构建搜索条件
        ProcessUtils.buildProcessSearch(historicProcessInstanceQuery, processQuery);
        int offset = pageQuery.getPageSize() * (pageQuery.getPageNum() - 1);
        List<HistoricProcessInstance> historicProcessInstances = historicProcessInstanceQuery
            .listPage(offset, pageQuery.getPageSize());
        page.setTotal(historicProcessInstanceQuery.count());
        List<WfTaskVo> taskVoList = new ArrayList<>();
        for (HistoricProcessInstance hisIns : historicProcessInstances) {
            WfTaskVo taskVo = new WfTaskVo();
            // 获取流程状态
            HistoricVariableInstance processStatusVariable = historyService.createHistoricVariableInstanceQuery()
                .processInstanceId(hisIns.getId())
                .variableName(ProcessConstants.PROCESS_STATUS_KEY)
                .singleResult();
            String processStatus = null;
            if (ObjectUtil.isNotNull(processStatusVariable)) {
                processStatus = Convert.toStr(processStatusVariable.getValue());
            }
            // 兼容旧流程
            if (processStatus == null) {
                processStatus = ObjectUtil.isNull(hisIns.getEndTime()) ? ProcessStatus.RUNNING.getStatus() : ProcessStatus.COMPLETED.getStatus();
            }
            Map<String, Object>  processVariables = hisIns.getProcessVariables();
            if(processVariables.containsKey("dataId")) {
            	taskVo.setDataId(processVariables.get("dataId").toString());
            }
            taskVo.setProcessStatus(processStatus);
            taskVo.setCreateTime(hisIns.getStartTime());
            taskVo.setFinishTime(hisIns.getEndTime());
            taskVo.setProcInsId(hisIns.getId());

            // 计算耗时
            if (Objects.nonNull(hisIns.getEndTime())) {
                taskVo.setDuration(DateUtils.getDatePoor(hisIns.getEndTime(), hisIns.getStartTime()));
            } else {
                taskVo.setDuration(DateUtils.getDatePoor(DateUtils.getNowDate(), hisIns.getStartTime()));
            }
            // 流程部署实例信息
            Deployment deployment = repositoryService.createDeploymentQuery()
                .deploymentId(hisIns.getDeploymentId()).singleResult();
            taskVo.setDeployId(hisIns.getDeploymentId());
            taskVo.setProcDefId(hisIns.getProcessDefinitionId());
            taskVo.setProcDefName(hisIns.getProcessDefinitionName());
            taskVo.setProcDefVersion(hisIns.getProcessDefinitionVersion());
            taskVo.setCategory(deployment.getCategory());
            // 当前所处流程
            List<Task> taskList = taskService.createTaskQuery().processInstanceId(hisIns.getId()).includeIdentityLinks().list();
            // 任务列表
            if (CollUtil.isNotEmpty(taskList)) {
            	taskVo.setTaskName(taskList.stream().map(Task::getName).filter(StringUtils::isNotEmpty).collect(Collectors.joining(",")));
            	taskVo.setTaskId(taskList.get(0).getId());
            } else {
                List<HistoricTaskInstance> historicTaskInstance = historyService.createHistoricTaskInstanceQuery().processInstanceId(hisIns.getId()).orderByHistoricTaskInstanceEndTime().desc().list();
                taskVo.setTaskId(historicTaskInstance.get(0).getId());
            }
            taskVoList.add(taskVo);
        }
        page.setRecords(taskVoList);
        return TableDataInfo.build(page);
	}

	@Override
	public List<WfTaskVo> selectAllProcessList(ProcessQuery processQuery) {
		HistoricProcessInstanceQuery historicProcessInstanceQuery = historyService.createHistoricProcessInstanceQuery()
                .orderByProcessInstanceStartTime()
                .desc();
        // 构建搜索条件
        ProcessUtils.buildProcessSearch(historicProcessInstanceQuery, processQuery);
        List<HistoricProcessInstance> historicProcessInstances = historicProcessInstanceQuery.list();
        List<WfTaskVo> taskVoList = new ArrayList<>();
        for (HistoricProcessInstance hisIns : historicProcessInstances) {
            WfTaskVo taskVo = new WfTaskVo();
            taskVo.setCreateTime(hisIns.getStartTime());
            taskVo.setFinishTime(hisIns.getEndTime());
            taskVo.setProcInsId(hisIns.getId());

            // 计算耗时
            if (Objects.nonNull(hisIns.getEndTime())) {
                taskVo.setDuration(DateUtils.getDatePoor(hisIns.getEndTime(), hisIns.getStartTime()));
            } else {
                taskVo.setDuration(DateUtils.getDatePoor(DateUtils.getNowDate(), hisIns.getStartTime()));
            }
            // 流程部署实例信息
            Deployment deployment = repositoryService.createDeploymentQuery()
                    .deploymentId(hisIns.getDeploymentId()).singleResult();
            taskVo.setDeployId(hisIns.getDeploymentId());
            taskVo.setProcDefId(hisIns.getProcessDefinitionId());
            taskVo.setProcDefName(hisIns.getProcessDefinitionName());
            taskVo.setProcDefVersion(hisIns.getProcessDefinitionVersion());
            taskVo.setCategory(deployment.getCategory());
            // 当前所处流程
            List<Task> taskList = taskService.createTaskQuery().processInstanceId(hisIns.getId()).includeIdentityLinks().list();
            if (CollUtil.isNotEmpty(taskList)) {
                taskVo.setTaskName(taskList.stream().map(Task::getName).filter(StringUtils::isNotEmpty).collect(Collectors.joining(",")));
            }
            taskVoList.add(taskVo);
        }
        return taskVoList;
	}

2、接口部分

java 复制代码

 
    /**
     *  所有的流程
     */
    @SaCheckPermission("workflow:process:allList")
    @GetMapping(value = "/allList")
    public TableDataInfo<WfTaskVo> allProcessList(ProcessQuery processQuery, PageQuery pageQuery) {
        return processService.selectPageAllProcessList(processQuery, pageQuery);
    }
 

    /**
     * 导出所有流程列表
     */
    @SaCheckPermission("workflow:process:allExport")
    @Log(title = "所有流程", businessType = BusinessType.EXPORT)
    @PostMapping("/allExport")
    public void allExport(@Validated ProcessQuery processQuery, HttpServletResponse response) {
        List<WfTaskVo> list = processService.selectAllProcessList(processQuery);
        List<WfOwnTaskExportVo> listVo = BeanUtil.copyToList(list, WfOwnTaskExportVo.class);
        for (WfOwnTaskExportVo exportVo : listVo) {
            exportVo.setStatus(ObjectUtil.isNull(exportVo.getFinishTime()) ? "进行中" : "已完成");
        }
        ExcelUtil.exportExcel(listVo, "所有流程", WfOwnTaskExportVo.class, response);
    }

3、效果图如下：
