mybatis的批量保存不用,非要循环去保存,一条sql变N条,作死

public void save(
            Long bannerId,
            List<BannerAddress> bannerAddresss) {
        if (!NumberHelper.greaterZero(bannerId)) {
            throw new BannerIdIsNullError();
        }

        delete(bannerId);

       for(BannerAddress bannerAddress bannerAddresss){
          dqi.Save(bannerAddress );
}
        
    }





public void save(
            Long bannerId,
            List<BannerAddress> bannerAddresss) {
        if (!NumberHelper.greaterZero(bannerId)) {
            throw new BannerIdIsNullError();
        }

        delete(bannerId);

        List<BannerAddress> saves = CollectionHelper.toList(bannerAddresss);

        if (saves.isEmpty()) {
            return;
        }

        saves.stream().forEach(e -> e.setBannerId(bannerId));

        dqi.batchSave(saves);
    }    

 <insert id="batchSave" parameterType="list">
        REPLACE INTO <include refid="main_table" />
        ( `provinceId`, `cityId`, `areaId`, `bannerId`,`provinceName`, `cityName`, `areaName`)
         VALUES
        <foreach collection="list" item="item" separator=",">
        (#{item.provinceId}, #{item.cityId}, #{item.areaId}, #{item.bannerId},#{item.provinceName}, #{item.cityName}, #{item.areaName})
        </foreach>
    </insert>

小细节 REPLACE INTO 重复就做更新操作
