这里我们可以看到我们的是 order_status cannot be null;
dataobiect OrderMaster
*/
@Entity
@Data
@DynamicUpdate
public class OrderMaster {
@Id
/*订单id*/
private String orderId;
/*买家名称*/
private String buyName;
/*买家电话*/
private String buyPhone;
/*买家地址*/
private String buyAdress;
/*买家的微信openid*/
private String buyOpenid;
/*订单总金额*/
private BigDecimal orderAmount;
/*订单状态 默认0 新下单 */
private Integer orderStatus = OrderStatusEnum.NEW.getCode();
/*支付状态 默认0 未支付*/
private Integer payStatus = OrderPayStatusEnum.WAITPAY.getCode();
/*创建时间*/
private Date createTime;
/*修改时间*/
private Date updateTime;
}
@Data
public class OrderMasterDTO {
/*订单id*/
private String orderId;
/*买家名称*/
private String buyName;
/*买家电话*/
private String buyPhone;
/*买家地址*/
private String buyAdress;
/*买家的微信openid*/
private String buyOpenid;
/*订单总金额*/
private BigDecimal orderAmount;
/*订单状态 默认0 新下单 */
private Integer orderStatus ;
/*支付状态 默认0 未支付*/
private Integer payStatus;
/*创建时间*/
private Date createTime;
/*修改时间*/
private Date updateTime;
/*订单详情列表*/
private List<OrderDetailsDTO> orderDetailsDTOList;
}
在orderMasterDTO中默认不会有orderId,orderStatus,payStatus,createTime,updateTime 的值，
看一下逻辑代码
//5.保存ordermaster
OrderMaster orderMaster = new OrderMaster();
BeanUtils.copyProperties(orderMasterDTO, orderMaster);
orderMaster.setOrderId(orderId);
orderMaster.setOrderAmount(orderAmount);
masterRepository.save(orderMaster);
在这里，我们在设置的时候是有默认值得，但是在cope后就没有值了，所以就是cope出了问题，
我们在cope的时候要把其余属性值设置在后边，就会正确的填写值了
