定义

在⽗类中提供⼀个创建对象的⽅法， 允许⼦类决定实例化对象的类型。

模拟发奖多种商品

在这⾥我们模拟积分兑换中的发放多种类型商品，假如现在我们有如下三种类型的商品接⼝

优惠券

CouponResult sendCoupon(String uId, String couponNumber, String uuid)

实物商品

Boolean deliverGoods(DeliverReq req)

第三⽅爱奇艺兑换卡

void grantToken(String bindMobileNumber, String cardId)

代码实现

定义发奖接⼝

public interface ICommodity {void sendCommodity(String uId, String commodityId, String bizId, Map<String, String> extMap) throws Exception;
}

实现奖品发放接⼝

优惠券

public class CouponCommodityService implements ICommodity {private Logger logger = LoggerFactory.getLogger(CouponCommodityService.class);private CouponService couponService = new CouponService();public void sendCommodity(String uId, String commodityId, String bizId, Map<String, String> extMap) throws Exception {CouponResult couponResult = couponService.sendCoupon(uId, commodityId, bizId);logger.info("请求参数[优惠券] => uId：{} commodityId：{} bizId：{} extMap：{}", uId, commodityId, bizId, JSON.toJSON(extMap));logger.info("测试结果[优惠券]：{}", JSON.toJSON(couponResult));if (!"0000".equals(couponResult.getCode())) throw new RuntimeException(couponResult.getInfo());}
}

实物商品

public class GoodsCommodityService implements ICommodity {private Logger logger = LoggerFactory.getLogger(GoodsCommodityService.class);private GoodsService goodsService = new GoodsService();public void sendCommodity(String uId, String commodityId, String bizId, Map<String, String> extMap) throws Exception {DeliverReq deliverReq = new DeliverReq();deliverReq.setUserName(queryUserName(uId));deliverReq.setUserPhone(queryUserPhoneNumber(uId));deliverReq.setSku(commodityId);deliverReq.setOrderId(bizId);deliverReq.setConsigneeUserName(extMap.get("consigneeUserName"));deliverReq.setConsigneeUserPhone(extMap.get("consigneeUserPhone"));deliverReq.setConsigneeUserAddress(extMap.get("consigneeUserAddress"));Boolean isSuccess = goodsService.deliverGoods(deliverReq);logger.info("请求参数[优惠券] => uId：{} commodityId：{} bizId：{} extMap：{}", uId, commodityId, bizId, JSON.toJSON(extMap));logger.info("测试结果[优惠券]：{}", isSuccess);if (!isSuccess) throw new RuntimeException("实物商品发放失败");}private String queryUserName(String uId) {return "花花";}private String queryUserPhoneNumber(String uId) {return "15200101232";}
}

第三⽅兑换卡

public class CardCommodityService implements ICommodity {private Logger logger = LoggerFactory.getLogger(CardCommodityService.class);// 模拟注⼊private IQiYiCardService iQiYiCardService = new IQiYiCardService();public void sendCommodity(String uId, String commodityId, String bizId, Map<String, String> extMap) throws Exception {String mobile = queryUserMobile(uId);iQiYiCardService.grantToken(mobile, bizId);logger.info("请求参数[爱奇艺兑换卡] => uId：{} commodityId：{} bizId：{} extMap：{}", uId, commodityId, bizId, JSON.toJSON(extMap));logger.info("测试结果[爱奇艺兑换卡]：success");}private String queryUserMobile(String uId) {return "15200101232";}
}

创建商店⼯⼚

public class StoreFactory {public ICommodity getCommodityService(Integer commodityType) {if (null == commodityType) return null;if (1 == commodityType) return new CouponCommodityService();if (2 == commodityType) return new GoodsCommodityService();if (3 == commodityType) return new CardCommodityService();throw new RuntimeException("不存在的商品服务类型");}
}

测试验证

@Test
public void test_commodity() throws Exception {StoreFactory storeFactory = new StoreFactory();// 1. 优惠券ICommodity commodityService_1 = storeFactory.getCommodityService(1);commodityService_1.sendCommodity("10001", "EGM1023938910232121323432", "791098764902132", null);// 2. 实物商品ICommodity commodityService_2 = storeFactory.getCommodityService(2);Map<String,String> extMap = new HashMap<String,String>();extMap.put("consigneeUserName", "方朋友");extMap.put("consigneeUserPhone", "15200292123");extMap.put("consigneeUserAddress", "吉林省.⻓春市.双阳区.XX街道.xx⼩区.#18-2109");commodityService_2.sendCommodity("10001","98198721311","1023020112221113", extMap);// 3. 第三⽅兑换卡(爱奇艺)ICommodity commodityService_3 = storeFactory.getCommodityService(3);commodityService_3.sendCommodity("10001","AQY1xjkUodl8LO975GdfrYUio",null ,null);
