     */
    @Override
    public Boolean hiddenSelfCheckUnitUserInfo(WghHiddenSelfCheckUnitPersonBo bo) {
        if (StringUtils.isBlank(bo.getPhone())){
            return false;
        }
        // 1.根据手机号查询db是否存在此记录
        Boolean flag;
        LambdaQueryWrapper<WghHiddenSelfCheckUnitPerson> lqw = Wrappers.lambdaQuery();
        lqw.eq(StringUtils.isNotBlank(bo.getPhone()),WghHiddenSelfCheckUnitPerson::getPhone,bo.getPhone());
        WghHiddenSelfCheckUnitPersonVo vo = baseMapper.selectVoOne(lqw);
        if (Objects.nonNull(vo)){
            //1.1是则为系统用户第一次登录，需绑定小程序openid
            //更新db
            UpdateWrapper<WghHiddenSelfCheckUnitPerson> updateWrapper = new UpdateWrapper<>();
            updateWrapper.eq("phone", bo.getPhone());
            updateWrapper.set("openid",bo.getOpenid());
            flag =  baseMapper.update(null,updateWrapper) > 0;
        }else {
            //1.2否，说明是自查自改单位人员，则新增（手机号、用户名、openid）
            //新增
            WghHiddenSelfCheckUnitPerson add = BeanUtil.toBean(bo, WghHiddenSelfCheckUnitPerson.class);
            flag = baseMapper.insert(add) > 0;
        }
        return flag;
    }
