警告
所有实体映射DO层必须继承pro.haichuang.framework.mybatis.domain.BaseDO
注意
BaseDO 基类自带三个默认字段,新建数据库表时必须与其一一对应
/**
* 唯一ID
*
* <p>默认使用雪花ID, 默认带上Validate的 {@code Group.Update} 类型验证
*/
@ApiModelProperty("ID")
@TableId(value = "id", type = IdType.ASSIGN_ID)
@JsonSerialize(using = ToStringSerializer.class)
@NotNull(message = "ID不能为空", groups = Group.Update.class)
private Long id;
/**
* 创建时间
*
* <p>新增时将自动填充当前时间
*/
@ApiModelProperty(value = "创建时间", hidden = true)
@TableField(value = "create_time", fill = FieldFill.INSERT)
private LocalDateTime createTime;
/**
* 最后修改时间
*
* <p>新增与修改时自动填充当前时间
*/
@ApiModelProperty(value = "最后修改时间", hidden = true)
