I have an issue with join tables on an object in an ORM class hierarchy where the join column is NOT the primary key of the base class due a lagacy database structure. Here is an example of the table design:
Code:
CREATE TABLE "SCH"."FOO"
(
"OWNERID" NUMBER(10,0) NOT NULL ENABLE,
"FOOID" NUMBER(10,0) NOT NULL ENABLE,
CONSTRAINT "FOO_PK" PRIMARY KEY ("OWNERID", "FOOID")
CONSTRAINT "FOO_FK1" FOREIGN KEY ("OWNERID") REFERENCES "SCH"."OWNERS" ("OWNERID") ENABLE
)
CREATE TABLE "SCH"."BAR"
(
"BARID" NUMBER(10,0) NOT NULL ENABLE,
"FOOID" NUMBER(10,0)
CONSTRAINT "BAR_PK" PRIMARY KEY ("BARID")
)
And here are the mappings (unesessary infomation removed)
Code:
@Entity
@IdClass(FooId.class)
@Table(name = "FOO")
public class Foo implements java.io.Serializable
{
@Id
@Column(name = "OWNERID")
private BigInteger ownerId;
@Id
@SequenceGenerator(name = "FOO_GENERATOR", sequenceName = "SEQ_FOO")
@GeneratedValue(generator = "FOO_GENERATOR")
@Column(name = "FOOID")
private BigInteger id;
@OneToMany(fetch = FetchType.LAZY)
@JoinColumn(name = "FOOID", referencedColumnName = "FOOID")
@Fetch(value = FetchMode.SUBSELECT)
@Cascade(value = {CascadeType.ALL})
private Set<Bar> bar = new LinkedHashSet<Bar>(0);
}
@Entity
@Table(name = "BAR")
public class Bar implements java.io.Serializable
{
@Id
@Column(name = "BARID")
private BigInteger id;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "FOOID", referencedColumnName = "FOOID")
private Foo foo;
}
This fails with an exception:
Code:
Caused by: org.hibernate.AnnotationException: referencedColumnNames(FOOID) of com.package.Bar.foo referencing com.package.Foo not mapped to a single property
at org.hibernate.cfg.BinderHelper.createSyntheticPropertyReference(BinderHelper.java:204)

at org.hibernate.cfg.Configuration.secondPassCompile(Configuration.java:1419)
at org.hibernate.cfg.Configuration.buildMappings(Configuration.java:1375)
Could you please help with a solution?
