代码设计
1、接口调用流程图
2、相关代码展示
以新增单品立减活动为例
API代码--MinusSellerController
@RestController
@RequestMapping("/seller/promotion/minus")
@Api(description = "单品立减相关API")
@Validated
public class MinusSellerController {
@ApiOperation(value = "添加单品立减", response = MinusVO.class)
@ApiImplicitParam(name = "minus", value = "单品立减信息", required = true, dataType = "MinusVO", paramType = "body")
@PostMapping
public MinusVO add(@ApiIgnore @Valid @RequestBody MinusVO minus) {
PromotionValid.paramValid(minus.getStartTime(),minus.getEndTime(),
minus.getRangeType(),minus.getGoodsList());
// 获取当前登录的店铺ID
Seller seller = UserContext.getSeller();
Long sellerId = seller.getSellerId();
minus.setSellerId(sellerId);
this.minusManager.add(minus);
return minus;
}
}
新增单品立减活动业务层代码--MinusManagerImpl
@Service
public class MinusManagerImpl extends AbstractPromotionRuleManagerImpl implements MinusManager {
@Override
@Transactional(propagation = Propagation.REQUIRED,
rollbackFor = {RuntimeException.class,
Exception.class, ServiceException.class})
public MinusVO add(MinusVO minusVO) {
//检测开始时间和结束时间
PromotionValid.paramValid(minusVO.getStartTime(),minusVO.getEndTime(),1,null);
this.verifyTime(minusVO.getStartTime(),minusVO.getEndTime(),
PromotionTypeEnum.MINUS,null);
//初步形成商品的DTO列表
List
//是否是全部商品参与
if(minusVO.getRangeType() == 1){
PromotionGoodsDTO goodsDTO = new PromotionGoodsDTO();
goodsDTO.setGoodsId(-1L);
goodsDTO.setSkuId(-1L);
goodsDTO.setGoodsName("全部商品");
goodsDTO.setThumbnail("path");
goodsDTOList.add(goodsDTO);
minusVO.setGoodsList(goodsDTOList);
}
//检测活动规则
this.verifyRule(minusVO.getGoodsList());
MinusDO minusDO = new MinusDO();
BeanUtils.copyProperties(minusVO,minusDO);
minusMapper.insert(minusDO);
// 获取活动Id
Long minusId = minusDO.getMinusId();
minusDO.setMinusId(minusId);
minusVO.setMinusId(minusId);
PromotionDetailDTO detailDTO = new PromotionDetailDTO();
detailDTO.setStartTime(minusVO.getStartTime());
detailDTO.setEndTime(minusVO.getEndTime());
detailDTO.setActivityId(minusVO.getMinusId());
detailDTO.setPromotionType(PromotionTypeEnum.MINUS.name());
detailDTO.setTitle(minusVO.getTitle());
//将活动商品入库
this.promotionGoodsManager.add(minusVO.getGoodsList(),detailDTO);
String minusKey = PromotionCacheKeys.getMinusKey(minusId);
cache.put(minusKey, minusDO);
//启用延时任务创建促销活动脚本信息
PromotionScriptMsg promotionScriptMsg = new PromotionScriptMsg();
promotionScriptMsg.setPromotionId(minusId);
promotionScriptMsg.setPromotionName(minusDO.getTitle());
promotionScriptMsg.setPromotionType(PromotionTypeEnum.MINUS);
promotionScriptMsg.setOperationType(ScriptOperationTypeEnum.CREATE);
promotionScriptMsg.setEndTime(minusDO.getEndTime());
String uniqueKey = "{TIME_TRIGGER_" + PromotionTypeEnum.MINUS.name()
+ "}_" + minusId;
timeTrigger.add(TimeExecute.SELLER_PROMOTION_SCRIPT_EXECUTER,
promotionScriptMsg, minusDO.getStartTime(), uniqueKey);
return minusVO;
}
}
单品立减促销活动脚本生成--PromotionScriptTimeTriggerExecuter

promotionScriptMsg, promotionScriptMsg.getEndTime(),
uniqueKey);
this.logger.debug("促销活动[" + promotionScriptMsg.getPromotionName()

@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}) {

<#--
单品立减活动金额计算
@param promotionActive 单品立减活动信息对象(内置常量)
.singleReductionValue 立减金额
@param $sku 商品SKU信息对象(变量)
.$price 商品SKU单价
.$num 商品数量
@returns {*}
-->
function countPrice() {
var resultPrice = ($sku.$price - ${promotionActive.singleReductionValue}) * $sku.$num;
