1、后端，在获取tod流程的时候加上dataId

// 流程发起人信息
            HistoricProcessInstance historicProcessInstance = historyService.createHistoricProcessInstanceQuery()
                .processInstanceId(task.getProcessInstanceId())
                .singleResult();
            String userId = historicProcessInstance.getStartUserId();
            String nickName = sysUserService.selectUserByUserName(userId).getNickName();
            flowTask.setStartUserId(userId);
            flowTask.setStartUserName(nickName);
            flowTask.setDataId(historicProcessInstance.getBusinessKey());

2、前端处理的时候加上dataId

// 跳转到处理页面
    handleProcess(row) {
      this.$router.push({
        path: '/workflow/process/detail/' + row.procInsId,
        query: {
          taskId: row.taskId,
          dataId: row.dataId,
          processed: true
        }
      })
    },

已经detail.vue里增加获取这个dataId

initData() {
      this.taskForm.procInsId = this.$route.params && this.$route.params.procInsId;
      this.taskForm.taskId  = this.$route.query && this.$route.query.taskId;
      this.taskForm.dataId  = this.$route.query && this.$route.query.dataId;
      this.processed = this.$route.query && eval(this.$route.query.processed || false);

3、后端对dataId的自自定义业务做回写处理

//处理自定义业务表单回写状态，节点与处理人信息
        if (StringUtils.isNotBlank(taskBo.getDataId())) {
        //业务数据id
            String dataId = taskBo.getDataId();
            //如果保存数据前未调用必调的FlowCommonService.initActBusiness方法，就会有问题
            WfMyBusiness business = wfMyBusinessService.getByDataId(dataId);
            //spring容器类名
            String serviceImplName = business.getServiceImplName();
            WfCallBackServiceI flowCallBackService = (WfCallBackServiceI) SpringContextUtils.getBean(serviceImplName);
            
            FlowNextDto flowNextDto = this.getNextFlowNode(taskBo.getTaskId(), taskBo.getVariables());
            if(flowNextDto != null) {
            //**有下一个节点
                UserTask nextUserTask = flowNextDto.getUserTask();
                //能够处理下个节点的候选人
                List<SysUser> nextFlowNodeUserList = flowNextDto.getUserList();
                List<String> newusername = new ArrayList<String>();
                if(nextFlowNodeUserList != null &&  nextFlowNodeUserList.get(0) != null ) {
                List<String> collect_username = nextFlowNodeUserList.stream().filter(Objects::nonNull).filter(item->item.getUserName()!=null).map(SysUser::getUserName).collect(Collectors.toList());
                //collect_username转换成realname
                // 流程发起人
                ProcessInstance processInstance = runtimeService.createProcessInstanceQuery().processInstanceId(taskBo.getProcInsId()).singleResult();
                String startUserId = processInstance.getStartUserId();
                if(taskBo.getVariables() !=null && taskBo.getVariables().containsKey("approval")) {//前端传回的变量值
                SysUser sysUser = commonService.getSysUserByUserName(taskBo.getVariables().get("approval").toString());
                newusername.add(sysUser.getNickName());
                }
                else {
                for (String oldUser : collect_username) {
                      if(StrUtil.equalsAnyIgnoreCase(oldUser,"${INITIATOR}")) {
                      SysUser sysUser = commonService.getSysUserByUserName(startUserId);
                          newusername.add(sysUser.getNickName());
                      }
                      else {
                     SysUser sysUser = commonService.getSysUserByUserName(oldUser);
                         newusername.add(sysUser.getNickName());
                      }
                    }
                }
                }
                
                //下一个实例节点
                List<Task> listtask = taskService.createTaskQuery().processInstanceId(business.getProcessInstanceId()).active().list();
                Task nexttask = null;
                if(listtask.size()==1) {
                nexttask = taskService.createTaskQuery().processInstanceId(business.getProcessInstanceId()).active().singleResult();
                }
                else {
                nexttask = taskService.createTaskQuery().processInstanceId(business.getProcessInstanceId()).active().list().get(0);
                }

                if(nextFlowNodeUserList !=null) {
                business.setActStatus(ActStatus.doing);
                business.setTaskId(nexttask.getId());
                business.setTaskNameId(nextUserTask.getId());
                business.setTaskName(nextUserTask.getName());
                business.setPriority(nextUserTask.getPriority());
                    business.setTodoUsers(JSON.toJSONString(newusername));
                }
                else {
                business.setActStatus(ActStatus.doing);
                business.setTaskId(nexttask.getId());
                business.setTaskNameId("");
                business.setTaskName("");
                business.setPriority("");
                    business.setTodoUsers("");
                }
                if(ObjectUtil.isNotEmpty(taskBo.getNextApproval())) {
                business.setActStatus(ActStatus.doing);
                business.setTaskId(nexttask.getId());
                business.setTaskNameId(nextUserTask.getId());
                business.setTaskName(nextUserTask.getName());
                business.setPriority(nextUserTask.getPriority());
                    business.setTodoUsers(taskBo.getNextApproval());
                }
            }
            else {//**没有下一个节点，流程已经结束了
            business.setActStatus(ActStatus.pass);
            business.setTaskId("");
            business.setTaskNameId("");
            business.setTaskName("");
                business.setTodoUsers("");
            }
            // 流程处理完后，进行回调业务层
            wfMyBusinessService.updateById(business);
            if (flowCallBackService!=null)flowCallBackService.afterFlowHandle(business);
        }
