       这个功能在已办任务里,就是用户可以通过已办任务,而且最好是发起人可以进行任务的收回,收回后可以重新进行业务流程提交。

     具体的代码如下,同时在自定义业务提交的时候做一个判断,符合这种情况可以进行提交:

@Override
	@Transactional(rollbackFor = Exception.class)
	public R recallProcess(WfTaskBo bo) {
		// 当前任务 listtask
    	List  listtask = taskService.createTaskQuery().processInstanceId(bo.getProcInsId()).active().list();
        if (listtask == null || listtask.size()==0) {
            throw new FlowableException("流程未启动或已执行完成,无法收回");
        }
        
    	if (taskService.createTaskQuery().taskId(listtask.get(0).getId()).singleResult().isSuspended()) {
            throw new FlowableException("任务处于挂起状态");
        }
    	
    	List procInsId = taskService.createNativeTaskQuery().sql("select * from ACT_HI_TASKINST where PROC_INST_ID_ = #{procInsId} ORDER BY START_TIME_ desc").parameter("procInsId", bo.getProcInsId()).list();
        
        String processInstanceId = listtask.get(0).getProcessInstanceId();

        //  获取所有历史任务(按创建时间升序)
        List hisTaskList = historyService.createHistoricTaskInstanceQuery()
        .processInstanceId(processInstanceId).orderByTaskCreateTime()
        .asc()
        .list();
        if (CollectionUtil.isEmpty(hisTaskList) || hisTaskList.size() < 2) {
            log.error("当前流程 【{}】 审批节点 【{}】正在初始节点无法收回", processInstanceId, listtask.get(0).getName());
            throw new FlowableException(String.format("当前流程 【%s】 审批节点【%s】正在初始节点无法收回", processInstanceId, listtask.get(0).getName()));
        }

        //  第一个任务
        HistoricTaskInstance startTask = hisTaskList.get(0);
        //若操作用户不是发起人,不能收回
        if(!StringUtils.equalsAnyIgnoreCase(LoginHelper.getUsername(), startTask.getAssignee())) {
        	throw new FlowableException("操作用户不是发起人,不能收回");
        }
        //  当前任务
        HistoricTaskInstance currentTask = hisTaskList.get(hisTaskList.size() - 1);

        BpmnModel bpmnModel = repositoryService.getBpmnModel(listtask.get(0).getProcessDefinitionId());

        //  获取第一个活动节点
        FlowNode startFlowNode = (FlowNode) bpmnModel.getMainProcess().getFlowElement(startTask.getTaskDefinitionKey());
        //  获取当前活动节点
        FlowNode currentFlowNode = (FlowNode) bpmnModel.getMainProcess().getFlowElement(currentTask.getTaskDefinitionKey());

        //  临时保存当前活动的原始方向
        List originalSequenceFlowList = new ArrayList<>(currentFlowNode.getOutgoingFlows());
        //  清理活动方向
        currentFlowNode.getOutgoingFlows().clear();

        //  建立新方向
        SequenceFlow newSequenceFlow = new SequenceFlow();
        newSequenceFlow.setId("newSequenceFlowId");
        newSequenceFlow.setSourceFlowElement(currentFlowNode);
        newSequenceFlow.setTargetFlowElement(startFlowNode);
        List newSequenceFlowList = new ArrayList<>();
        newSequenceFlowList.add(newSequenceFlow);
        //  当前节点指向新的方向
        currentFlowNode.setOutgoingFlows(newSequenceFlowList);

        //  完成当前任务
        for(Task task : listtask) {
		    taskService.addComment(task.getId(), listtask.get(0).getProcessInstanceId(),FlowComment.RECALL.getType(), "发起人收回");
		    taskService.setAssignee(task.getId(), startTask.getAssignee());
		    taskService.complete(task.getId());
        }
        

        //  重新查询当前任务
        Task nextTask = taskService.createTaskQuery().processInstanceId(processInstanceId).singleResult();
        if (ObjectUtil.isNotNull(nextTask)) {
            taskService.setAssignee(nextTask.getId(), startTask.getAssignee());
            //taskService.complete(nextTask.getId());;//跳过流程发起节点
        }
        //自定义业务处理id
        String dataId = bo.getDataId();
        if(StringUtils.isNotEmpty(dataId)) {
        	WfMyBusiness business = wfMyBusinessService.getByDataId(dataId);
