关于spring:提交商品订单-SysResult

SysResult
个别后端业务解决实现之后，须要给客户端返回无效信息，告知客户端程序执行是否正确

@Data
@Accessors(chain = true)
@NoArgsConstructor
@AllArgsConstructor
public class SysResult {
 private Integer status;
 private String msp;// 服务器提示信息 胜利 失败
 private Object data;// 服务器返回值数据
 // 利用 static 的静态方法 将数据动静返回
 public static SysResult fail(){return new SysResult(201,"业务执行失败",null);
 }
 public static SysResult success(){return new SysResult(200,"业务执行胜利",null);
 }
 public static SysResult success(Object data){return new SysResult(200,"业务执行胜利",data);
 }
 public static SysResult success(String msp,Object data){return new SysResult(200,msp,data);
 }
}

实现提交订单

 @RequestMapping("submit")
 @ResponseBody
public SysResult submit(Order order){Long userId = UserLocalThread.get().getId();
 String orderId=dubboOrderService.saveOrder(order);
 if(StringUtils.isEmpty(orderId)){return SysResult.fail();
 }else {return SysResult.success(orderId);
 }
 }

@Autowired
private OrderMapper orderMapper;
@Autowired
private OrderShippingMapper orderShippingMapper;
@Autowired
private OrderItemMapper orderItemMapper;
 @Override
 public String saveOrder(Order order) {
 //1. 拼接 orderID = 用户 id 加工夫戳
 String orderId=order.getUserId()+""+System.currentTimeMillis();
 order.setOrderId(orderId).setStatus(1);
 int i = orderMapper.insert(order);// 订单入库
 // 实现订单物流入库
 OrderShipping orderShipping = order.getOrderShipping();
 orderShipping.setOrderId(orderId);// 订单物流增加订单 id
 orderShippingMapper.insert(orderShipping);
 // 实现订单商品入库
 List<OrderItem>orderItems=order.getOrderItems();
 for (OrderItem orderItem:orderItems){orderItem.setOrderId(orderId);
 orderItemMapper.insert(orderItem);
 System.out.println("商品入库胜利");
 }
 return orderId;
 }
