I have 3 entities BaseFoo
, FooAbc
, FooAbcDetail
. FooAbc
extends base entity BaseFoo
. I'm trying to do one to one relation between FooAbc
and FooAbcDetail
.
@Data
@EqualsAndHashCode(callSuper = true)
@Entity
@Table(name = "foo")
@Audited
@AuditOverride(forClass = Auditable.class)
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name = "type_id", discriminatorType = DiscriminatorType.INTEGER)
public abstract class BaseFoo extends Auditable implements Serializable {
@Id
@Column(name = "id")
private Long id;
//other fields
}
@Data
@EqualsAndHashCode(callSuper = true)
@Entity
@Audited
@AuditOverride(forClass = BaseFoo.class)
@DiscriminatorValue("2")
public class FooAbc extends BaseFoo implements Serializable {
@EqualsAndHashCode.Exclude
@ToString.Exclude
@NotAudited
@OneToOne(mappedBy = "fooAbc",
fetch = FetchType.LAZY,
cascade = CascadeType.ALL,
orphanRemoval = true,
optional = false)
private FooAbcDetail fooAbcDetail;
//other fields
}
@Data
@Entity
@Table(name = "foo_abc_detail")
public class FooAbcDetail implements Serializable {
@Id
@Column(name = "foo_id"/* foo_abc_id (I tried both) */)
private Long id;
@ToString.Exclude
@EqualsAndHashCode.Exclude
@MapsId //also tried @MapsId("id")
@OneToOne(fetch = FetchType.LAZY)
private FooAbc fooAbc; //also tried BaseFoo
//other fields
}
While project starting up Hibernate throws:
org.hibernate.MappingException: Unable to find column with logical name: id in org.hibernate.mapping.Table(public.foo_abc_detail) and its related supertables and secondary tables
What is the problem here?
Environment
This error is telling you that there is no column on the foo_abc_detail
table called foo_id
.The column on foo_abc_detail
is just called id
.
@Data
@EqualsAndHashCode(callSuper = true)
@Entity
@Table(name = "foo")
@Audited
@AuditOverride(forClass = Auditable.class)
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
@DiscriminatorColumn(name = "type_id", discriminatorType = DiscriminatorType.INTEGER)
public abstract class BaseFoo extends Auditable implements Serializable {
@Id
@Column(name = "id")
private Long id;
//other fields
}
@Data
@EqualsAndHashCode(callSuper = true)
@Entity
@Audited
@AuditOverride(forClass = BaseFoo.class)
@DiscriminatorValue("2")
public class FooAbc extends BaseFoo implements Serializable {
@EqualsAndHashCode.Exclude
@ToString.Exclude
@NotAudited
@OneToOne(mappedBy = "fooAbc",
fetch = FetchType.LAZY,
cascade = CascadeType.ALL,
orphanRemoval = true,
optional = false)
private FooAbcDetail fooAbcDetail;
//other fields
}
@Data
@Entity
@Table(name = "foo_abc_detail")
public class FooAbcDetail implements Serializable {
@Id
@Column(name = "id")
private Long id;
@ToString.Exclude
@EqualsAndHashCode.Exclude
@MapsId //also tried @MapsId("id")
@OneToOne(fetch = FetchType.LAZY)
private FooAbc fooAbc; //also tried BaseFoo
//other fields
}
Okey I solved. I don't know if this is the best way to do it but it works! I replaced the @MapsId
annotation via @JoinColumn
. Final result of the FooAbcDetail
class like as below.
@Data
@Entity
@Table(name = "foo_abc_detail")
public class FooAbcDetail implements Serializable {
@Id
@Column(name = "id")
private Long id;
@ToString.Exclude
@EqualsAndHashCode.Exclude
@OneToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "id", referencedColumnName = "id", nullable = false)
private FooAbc fooAbc;
