Hibernate使用注解

//类标志@Entity@Table(name = "TC_CONTACT")public class TContract extends BaseDomain//id主键标志@Id@GeneratedValue(generator = "identifier", strategy = GenerationType.IDENTITY)@SequenceGenerator(name = "identifier", allocationSize = 1)@Column(name = "ID")//列标示@Column(name = "link_man_no", nullable = false, insertable = false, updatable = false)@Column(name = "CREATED_ON", unique = false, insertable = false, updatable = false)@Transientprivate String updateTime;//多对一@ManyToOne(targetEntity = TactivatableItem.class)@Cascade(value = {CascadeType.PERSIST, CascadeType.MERGE })@JoinColumn(name = "LINE_ITEM_ID")public TactivatableItem getActivatableItem(){   return activatableItem;}//一对多@OneToMany(targetEntity = TentitlementFeatureDetail.class, fetch = FetchType.EAGER, mappedBy = "feature")@Cascade(value = {CascadeType.DELETE_ORPHAN, CascadeType.SAVE_UPDATE })public List<TentitlementFeatureDetail> getDetailList(){    return detailList;}@OneToMany(fetch = FetchType.LAZY, mappedBy = "tactivatableItem", targetEntity = Tfulfillment.class)@Cascade(value = {CascadeType.SAVE_UPDATE, CascadeType.DELETE_ORPHAN })@OneToMany(targetEntity = TentitlementFeature.class, fetch = FetchType.LAZY, mappedBy = "activatableItem")@Cascade(value = {CascadeType.DELETE_ORPHAN, CascadeType.SAVE_UPDATE })//多对多@ManyToOne(targetEntity = Tproduct.class)@Cascade(value = {CascadeType.PERSIST, CascadeType.MERGE })@JoinColumn(name = "PRODUCT_ID")@ManyToOne(fetch = FetchType.LAZY, targetEntity = TLogoInfo.class)@NotFound(action = NotFoundAction.IGNORE)@JoinColumn(name = "LOGO_INFO_ID")
