自定义SQL查询的使用

@Override
public Map<String, Object> getActvityUrl(String appId) {
    logger.info("根据appid获取活动地址开始：{}", appId);
    LambdaQueryWrapper<CustomerConfigPO> queryWrapper = new QueryWrapper<CustomerConfigPO>().lambda();
    queryWrapper.eq(CustomerConfigPO::getAppId, appId);
    CustomerConfigPO CustomerConfigPO = getOne(queryWrapper);
    return CustomerConfigPO == null ? null : CustomerConfigPO.toMaps();
}
