练习：将值是null的数据删除掉（剔除）:com.fasterxml.jackson.annotation.JsonInclude;包
例如，有数据是null，不想展示
{
"statusCode": 0,
"message": "返回成功",
"data": [{
"orderId": "1542785381425923730",
"buyerName": "王五",
"buyerPhone": "15605852476",
"buyerAddr": "北京王府井",
"buyerOpenid": "110112",
"buyerAmount": 4.40,
"orderStatus": 0,
"payStatus": 0,
"createTimestamp": 1542794276000,
"updateTimestamp": 1542794276000,
"orderDetailList": null
}]
}
解决方法：
在输出格式的entity/vo/dto添加com.fasterxml.jackson.annotation.JsonInclude;包的注解
@JsonInclude(JsonInclude.Include.NON_NULL)
/**订单*/
@Data //get/set
//将值是null的数据剔除
@JsonInclude(JsonInclude.Include.NON_NULL)
public class OrderDTO {
private String orderId;
/**买家名字**/
private String buyerName;
/**买家手机**/
private String buyerPhone;
/**买家地址**/
private String buyerAddr;
/**用户openid**/
private String buyerOpenid;
/**订单金额**/
private BigDecimal buyerAmount;
/**订单状态, 默认状态0新订单**/
private Integer orderStatus;
/**支付状态, 默认状态0等待支付**/
private Integer payStatus;
private Date createTimestamp;
private Date updateTimestamp;
List<OrderDetail> orderDetailList;
}
