IOrderDomainService给网关调用，接收一个参数orderType，比如createOrder(CreateOrderRequest req)

=======================================================================================================

class OrderDomainService

 

public CreateOrderResult createOrder(CreateOrderRequest request) {

　　//参数验证

　　return this.getOrderService(request.getOrderType().toString()).createOrder(request);

}

 

private IOrderService getOrderService(String orderType) {
　　　　String className = String.format("orderService%s", orderType);
　　　　IOrderService orderService = MyApplicationContext.getInstance().getBean(className, IOrderService.class, false);
　　　　if (orderService == null) {
　　　　　　throw new ServiceException(String.format("合作方订单服务未定义[%s]", orderType), ServiceException.NOT_EXIST);
　　　　}
　　　　return orderService;
}

@Service("orderService1")
public class Child1OrderService extends AbstractOrderService implements IChild1OrderService

 

 

@Service("orderService2")
public class Child2OrderService extends AbstractOrderService implements IChild2OrderService
