Question

我正在尝试使用Hibernate保存使用查找表（lookupvalue）的父实体（兴趣）。当我持久感兴趣对象（em.persists(interest)）时，所有列都被保存，但categoryLookupValue.Any线索除外？以下是表格的详细信息

CREATE TABLE interest.interest
(
  id bigint NOT NULL,
  interestname character varying NOT NULL,
  summary character varying NOT NULL,
  legislation character varying,
  description character varying,
  categorylookupvalue integer,<= This column is not saved
  dictionarystartdate date,
  pirstartdate date,
  pirenddate date,
  affectpropertybeforedetail character varying,
  affectpropertyafterdetail character varying,
  CONSTRAINT pk_interest PRIMARY KEY (id),
  CONSTRAINT fk_interest_category FOREIGN KEY (categorylookupvalue)
      REFERENCES reference.lookupvalue (id) MATCH SIMPLE
      ON UPDATE NO ACTION ON DELETE NO ACTION
)

CREATE TABLE reference.lookupdomain
(
  id integer NOT NULL,
  name character varying(100) NOT NULL,
  CONSTRAINT pk_lookupdomain PRIMARY KEY (id)
)

CREATE TABLE reference.lookupvalue
(
  id integer NOT NULL,
  lookupvalue_lookupdomain_id integer NOT NULL,
  domaincode character varying NOT NULL,
  domainvalue character varying NOT NULL,
  CONSTRAINT pk_lookupvalue PRIMARY KEY (id),
  CONSTRAINT fk_lokupvalue_lookupdomain_id FOREIGN KEY (lookupvalue_lookupdomain_id)
      REFERENCES reference.lookupdomain (id) MATCH SIMPLE
      ON UPDATE NO ACTION ON DELETE NO ACTION
)

这是实体

public class Interest implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "id_seq")
    @SequenceGenerator(name = "id_seq", sequenceName = "id_seq")
    private Long id;

    @NotNull
    private String interestName;

    @Basic
    private String description;

   // Do not cascade as LookupValue is just for lookup
    @OneToOne(fetch = FetchType.EAGER, optional = false)
    // set insertable = false, updatable = false to ensure that JPA doesnt try to update/delete lookup table
    @JoinColumn(name = "categorylookupvalue",referencedColumnName = "id",insertable = false, updatable = false,nullable = false)
    private LookupValue categoryLookupValue;
    ..other fileds
}

public class LookupValue implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "id_seq")
    @SequenceGenerator(name = "id_seq", sequenceName = "id_seq")
    private Long id;

    @Column(name = "lookupvalue_lookupdomain_id")
    private Long lookupvalue_lookupdomain_id;

    @Column(name = "domaincode")
    private String domainCode;

    @Column(name = "domainvalue")
    private String domainValue;
}

public class LookupDomain implements Serializable {
    @Id
    @GeneratedValue(generator = "id_seq")
    @SequenceGenerator(name = "id_seq", sequenceName = "id_seq")
    private Long id;

    @Column(name = "name")
    private String name;

    @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
    @JoinColumns({
            @JoinColumn(name = "lookupvalue_lookupdomain_id", referencedColumnName = "id", insertable = false, updatable = false)
    })
    private List<LookupValue> lookupValue = new ArrayList<>();

}

JPA-Hibernate OneToOne，查找表未保存映射列
