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
