實體類和數據庫表通常是一一對應,一般稱之爲entity
,以用戶表爲例:Lombok傳送門html
/** * AdUser for 數據庫ad_user表對應的實體類 * {@link Basic} 標示爲數據庫的字段信息,若是須要一個不屬於數據庫的字段,標註爲 {@link Transient} * * @author <a href="mailto:magicianisaac@gmail.com">Isaac.Zhang</a> * @since 2019/6/15 */ @Data @AllArgsConstructor @NoArgsConstructor @Entity @Table(name = "ad_user") public class AdUser { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name = "user_id", nullable = false) private Long userId; @Basic //不寫的話,默認就是@Basic,表示是數據庫表的一個字段 //@Transient //若是打上@Transient 註解,代表當前字段不是表中的字段 @Column(name = "user_name", nullable = false) private String userName; @Basic @Column(name = "token", nullable = false) private String token; @Basic @Column(name = "user_status", nullable = false) private Integer userStatus; @Basic @Column(name = "create_time", nullable = false) private Date createTime; @Basic @Column(name = "update_time", nullable = false) private Date updateTime; /** * 建立用戶時所需的必填字段 * * @param user_name 用戶名稱 * @param token token */ public AdUser(String user_name, String token) { this.userName = user_name; this.token = token; this.userStatus = CommonStatus.VALID.getStatus(); this.createTime = new Date(); this.updateTime = this.createTime; } } --- /** * CommonStatus for 通用狀態枚舉 * * @author <a href="mailto:magicianisaac@gmail.com">Isaac.Zhang</a> */ @Getter public enum CommonStatus { VALID(1, "有效"), INVALID(0, "無效狀態"); private Integer status; private String desc; CommonStatus(Integer status, String desc) { this.status = status; this.desc = desc; } }
其餘的數據庫對應實體類(AdUnit
,AdPlan
,AdCreative
,AdUnitDistrict
,AdUnitHobby
,AdUnitKeyword
,RelationshipCreativeUnit
),你們能夠參考上面的例子本身實現,也能夠去github上下載源碼。------
作一個好人。
