接口定义
public interface ICommonService {public Object handler(String json);
}银行卡消费
Service
CodeType(01)
public class BankConsumService implements ICommonService{Overridepublic Object handler(String json) {System.out.println(银行卡消费开始 json);return bank-consum;}
}银行卡退货
Service
CodeType(02)
public class BankRefundService implements ICommonService{Overridepublic Object handler(String json) {System.out.println(银行卡退货开始 json);return bank-refund;}
}社保卡消费
Service
CodeType(11)
public class SocConsumService implements ICommonService{Overridepublic Object handler(String json) {System.out.println(社保卡消费开始 json);return soc-consum;}
}社保卡退货
Service
CodeType(12)

RestController
public class ServerController {private final MapString, ICommonService handlerMap new HashMap();Autowiredprivate void setHandler(ListICommonService commonServiceList) {for (ICommonService commonService : commonServiceList) {handlerMap.put(commonService.getClass().getAnnotation(CodeType.class).value(), commonService);}}AnonymousRequestMapping(/api)public Object api(RequestBody PosApiReq posApiReq) {String transWay posApiReq.getTransWay();String transType posApiReq.getTransType();// 01 银行卡消费、02银行卡退货、11 社保卡消费、 12社保卡退货String value transWaytransType;ICommonService commonService handlerMap.get(value);Object object commonService.handler(posApiReq.toString());return object;}
}annotation
Target(value{ElementType.TYPE, ElementType.METHOD})
Retention(RetentionPolicy.RUNTIME)
public interface CodeType {String value();
}此方式完美的解决了根据不通交易调用不通逻辑的问题如果新添加一类交易只需要扩展实现ICommonService 接口的新类就可以。
