关于重排序的，工作中遇到的问题

Question

public OutboundOrderVO save(OutboundOrderAddDTO dto) {
        int dataDependency = 0;
        OutboundOrder model = BeanUtil.toBean(dto, OutboundOrder.class);
        model.setCompanyId(SecurityUtils.getCompanyId());
        model.setCreateId(SecurityUtils.getLoginUser().getStaffId());
        // 判断仓库是否可以出入库
        List<String> consumableIds = dto.getInfoList().stream().map(OutboundInfoAddDTO::getConsumableId).collect(Collectors.toList());
        // 根据耗材id查询所在仓库
        List<Consumables> consumablesList = consumablesService.listByIds(consumableIds);
        Set<String> wareHouseIds = consumablesList.stream().map(Consumables::getWarehouseId).collect(Collectors.toSet());
        List<String> lockingList = wareHouseService.findByIds(wareHouseIds, CommonConstant.WARE_HOUSE_LOCKING).stream().map(WareHouse::getId).collect(Collectors.toList());
        if (CollectionUtil.isNotEmpty(lockingList)) {
            // 所选耗材中存在仓库已经锁定，不能出库
            dataDependency = 1;
            List<Consumables> lockingConsumables = consumablesList.stream().filter(t -> lockingList.contains(t.getWarehouseId())).collect(Collectors.toList());
            StringBuffer msg = new StringBuffer();
            for (int i = 0; i < lockingConsumables.size(); i++) {
                msg.append(lockingConsumables.get(i).getConsumablesName());
                if (i != lockingConsumables.size() - 1) {
                    msg.append(",");
                }
            }
            throw new BizException("耗材:" + msg + "所在仓库暂时禁止出入库");
        }
        dataDependency = 2;
        // 获取流程审批单号单号
        ProcedureAddDTO procedureAddDTO = dto.getProcedureAddDTO();
        if (procedureAddDTO == null) {
            throw new BizException("流程数据不能为空");
        }
        String processId= FlowCodeUtils.getFlowCode();
        model.setProcessId(processId);
        procedureAddDTO.setNumberId(processId);
        boolean isOdoType = false;
        if ((isOdoType = CommonConstant.ODO_TYPE.equals(model.getOdoType())) || CommonConstant.ODO_TYPE_SELF_APPLY.equals(model.getOdoType())) {
            int y = dataDependency;
            if(isOdoType){
                model.setOdoCode(CommonConstant.CK_CHAR + CodeRandom.getRandom(CommonConstant.CODE_RANDOM_BIT));
            }else {
                model.setOdoCode(CommonConstant.ZZCK_CHAR + CodeRandom.getRandom(CommonConstant.CODE_RANDOM_BIT));
            }
            // 设置出库单的初始状态为：派发待确认
            model.setOdoStatus(CommonConstant.ODO_DISTRIBUTION_CONFIRMING);
            super.save(model);
            try {
                dataDependency = 3;
                remoteFlowService.remoteSaveProduce(procedureAddDTO);
            } catch (RuntimeException e) {
                throw new BizException("发起流程失败，请联系管理员");
            }
            // 新增出库详情
            String odoId = model.getId();
            dto.getInfoList().forEach(e -> outboundInfoService.save(e, odoId));
            return BeanUtil.toBean(model, OutboundOrderVO.class);
        } else {
            dataDependency = 4;
            //  出库申请
            return outApplySave(model, dto.getInfoList(),dto.getProcedureAddDTO());
        }
    }

dataDependency变量是我后面加的。没加之前出现了问题：
下面这句代码执行了，抛出了异常。这句代码在源代码中的前面

throw new BizException("耗材:" + msg + "所在仓库暂时禁止出入库");

但是在下面的这句代码也执行了，按道理下面这个去新增的代码不应该执行，或许是因为重排序。所以我用dataDependency 添加数据依赖防止重排序，但不确定是否正确。

remoteFlowService.remoteSaveProduce(procedureAddDTO);

把需要排序的类实现Comparable接口。
