第二件半价促销活动属于商家店铺可直接发布的促销活动,同一个商家在同一时间段内只允许创建一个第二件半价促销活动。那么,第二件半价促销活动的代码设计是怎么样的?下面易族智汇javashop为您解析,欢迎阅读参考。
代码设计
1、接口调用流程图
2、相关代码展示
以新增第二件半价活动为例
API代码--HalfPriceSellerController
@RestController
@RequestMapping("/seller/promotion/half-prices")
@Api(description = "第二件半价相关API")
@Validated
public class HalfPriceSellerController {
@ApiOperation(value = "添加第二件半价", response = HalfPriceVO.class)
@PostMapping
public HalfPriceVO add(@Valid @RequestBody HalfPriceVO halfPrice) {
PromotionValid.paramValid(halfPrice.getStartTime(),halfPrice.getEndTime(),
halfPrice.getRangeType(),halfPrice.getGoodsList());
// 获取当前登录的店铺ID
Seller seller = UserContext.getSeller();
Long sellerId = seller.getSellerId();
halfPrice.setSellerId(sellerId);
this.halfPriceManager.add(halfPrice);
return halfPrice;
}
}
新增第二件半价活动业务层代码--HalfPriceManagerImpl
@Service
public class HalfPriceManagerImpl extends AbstractPromotionRuleManagerImpl implements HalfPriceManager {
@Override
@Transactional(propagation = Propagation.REQUIRED,
rollbackFor = {RuntimeException.class, Exception.class,
ServiceException.class, NoPermissionException.class})
public HalfPriceVO add(HalfPriceVO halfPriceVO) {
//检测开始时间和结束时间
PromotionValid.paramValid(halfPriceVO.getStartTime(),
halfPriceVO.getEndTime(), 1, null);
this.verifyTime(halfPriceVO.getStartTime(),
halfPriceVO.getEndTime(), PromotionTypeEnum.HALF_PRICE, null);
//初步形成商品的DTO列表
List
//是否是全部商品参与
if (halfPriceVO.getRangeType() == 1) {
PromotionGoodsDTO goodsDTO = new PromotionGoodsDTO();
goodsDTO.setGoodsId(-1L);
goodsDTO.setSkuId(-1L);
goodsDTO.setGoodsName("全部商品");
goodsDTO.setThumbnail("");
goodsDTOList.add(goodsDTO);
halfPriceVO.setGoodsList(goodsDTOList);
}
this.verifyRule(halfPriceVO.getGoodsList());
HalfPriceDO halfPriceDO = new HalfPriceDO();
BeanUtils.copyProperties(halfPriceVO, halfPriceDO);
this.halfPriceMapper.insert(halfPriceDO);
Long id = halfPriceDO.getHpId();
halfPriceVO.setHpId(id);
PromotionDetailDTO detailDTO = new PromotionDetailDTO();
detailDTO.setStartTime(halfPriceVO.getStartTime());
detailDTO.setEndTime(halfPriceVO.getEndTime());
detailDTO.setActivityId(halfPriceVO.getHpId());
detailDTO.setPromotionType(PromotionTypeEnum.HALF_PRICE.name());
detailDTO.setTitle(halfPriceVO.getTitle());
//将活动商品入库
this.promotionGoodsManager.add(halfPriceVO.getGoodsList(), detailDTO);
cache.put(PromotionCacheKeys.getHalfPriceKey(
halfPriceVO.getHpId()), halfPriceDO);
//启用延时任务创建促销活动脚本信息
PromotionScriptMsg promotionScriptMsg = new PromotionScriptMsg();
promotionScriptMsg.setPromotionId(id);
promotionScriptMsg.setPromotionName(halfPriceDO.getTitle());
promotionScriptMsg.setPromotionType(PromotionTypeEnum.HALF_PRICE);
promotionScriptMsg.setOperationType(ScriptOperationTypeEnum.CREATE);
promotionScriptMsg.setEndTime(halfPriceDO.getEndTime());
String uniqueKey = "{TIME_TRIGGER_" + PromotionTypeEnum.HALF_PRICE.name()
+ "}_" + id;
timeTrigger.add(TimeExecute.SELLER_PROMOTION_SCRIPT_EXECUTER,
promotionScriptMsg, halfPriceDO.getStartTime(), uniqueKey);
return halfPriceVO;
}
}
第二件半价促销活动脚本生成--PromotionScriptTimeTriggerExecuter
@Component("promotionScriptTimeTriggerExecuter")
public class PromotionScriptTimeTriggerExecuter implements TimeTriggerExecuter {
@Override
public void execute(Object object) {
PromotionScriptMsg promotionScriptMsg = (PromotionScriptMsg) object;
//如果是促销活动开始
if (ScriptOperationTypeEnum.CREATE
.equals(promotionScriptMsg.getOperationType())) {
//创建促销活动脚本
this.createScript(promotionScriptMsg);
//促销活动开始后,立马设置一个促销活动结束的流程
promotionScriptMsg.setOperationType(ScriptOperationTypeEnum.DELETE);
String uniqueKey = "{TIME_TRIGGER_"
+ promotionScriptMsg.getPromotionType().name() + "}_"
+ promotionScriptMsg.getPromotionId();
timeTrigger.add(TimeExecute.SELLER_PROMOTION_SCRIPT_EXECUTER,
promotionScriptMsg, promotionScriptMsg.getEndTime(),
uniqueKey);
this.logger.debug("促销活动[" + promotionScriptMsg.getPromotionName()
+ "]开始,id=[" + promotionScriptMsg.getPromotionId()
+ "]");
} else {
//删除缓存中的促销脚本数据
this.deleteScript(promotionScriptMsg);
this.logger.debug("促销活动[" + promotionScriptMsg.getPromotionName()
+ "]结束,id=[" + promotionScriptMsg.getPromotionId()
+ "]");
}
}

第二件半价促销活动脚本引擎模板文件—half_price.ftl
<#--
验证促销活动是否在有效期内
@param promotionActive 活动信息对象(内置常量)
.startTime 获取开始时间
.endTime 活动结束时间
@param $currentTime 当前时间(变量)
@returns {boolean}
-->
function validTime(){
if (${promotionActive.startTime} <= $currentTime && $currentTime <= ${promotionActive.endTime}) {
return true;
}
return false;
}
<#--
第二件半价促销活动金额计算
@param $sku 商品SKU信息对象(变量)
.$price 商品SKU单价
.$num 商品数量
@returns {*}
-->
function countPrice() {
<#--获取实际商品总金额-->
var totalPrice = $sku.$price * $sku.$num;
<#--应该优惠的金额-->
var discountPrice = 0.00;
<#--当商品数量大于1时才计算优惠-->
if ($sku.$num > 1) {
<#--如果商品数量对2进行取余得到的结果为0-->
if ($sku.$num % 2 == 0) {
<#--优惠金额 = 商品原价的一半 * 商品数量的一半-->
discountPrice = ($sku.$price / 2) * ($sku.$num / 2);
}
<#--如果商品数量对2进行取余得到的结果为1-->
if ($sku.$num % 2 == 1) {
<#--优惠金额 = 商品原价的一半 * (商品数量 - 1)的一半-->
discountPrice = ($sku.$price / 2) * (($sku.$num - 1) / 2);
}
}
<#--最终返回优惠后的总金额 = 实际商品总金额 - 优惠金额-->
totalPrice = totalPrice - discountPrice;
return totalPrice < 0 ? 0 : totalPrice.toString();
