Description
https://hibernate.atlassian.net/browse/HHH-2872
I get a MappingException for @ManyToOne join if table on the left of the association is alphabetically lower than table on the right
I have tables VO_USER, V_ORGANIZATIONAL and VO_AREA
VO_USER has USR_IDR as primary key.
V_ORGANIZATIONAL has a composite primary key of BUSINESS_AREA_CODE and CODE
VO_AREA has BUS_ARA_IDR as the primary key
I get the following exception when I join the VO_USER table with the V_ORGANIZATIONAL table
"org.hibernate.MappingException: Unable to find column with logical name: BUSINESS_AREA_CODE in org.hibernate.mapping.Table(V_ORGANIZATIONAL_GRADE) and its related supertables and secondary tables"
Howerver, if I rename the table V_ORGANIZATIONAL to VO_ORGANIZATIONAL, it works fine - which makes me conclude that it is an issue with the alphabetical ordering of the tables in the association. The table name on the left side of the @ManyToOne join must be alphabetically greater than the table on the right side - perhaps of the way hibernate loads the classes ??
Can someone confirm that is the issue, and what is the workaround/solution as I dont want to change the name of the table
The simplified Code :
@Entity @org.hibernate.annotations.Entity(mutable = true) @Table(name = "VO_USER") @Cache(usage = CacheConcurrencyStrategy.READ_WRITE, region = "user") public class User implements Serializable { private static final long serialVersionUID = -1894472442328538017L; @Id @Column(name = "USR_IDR") private String userId; @ManyToOne @JoinColumn(name = "BUS_ARA_IDR", insertable = false, updatable = false, unique = false, nullable = false) private BusinessArea businessArea; @ManyToOne(targetEntity = Organizational.class) @JoinColumns( { @JoinColumn(name = "BUS_ARA_IDR", referencedColumnName = "BUSINESS_AREA_CODE", unique = false, insertable = false, updatable = false, nullable=true), @JoinColumn(name = "USR_GRD", referencedColumnName = "CODE", unique = false, insertable = false, updatable = false, nullable=true) } ) private Organizational organizational; .... }
@Entity @Table(name = "V_ORGANIZATIONAL") @IdClass(OrganizationalKey.class) @Cache(usage = CacheConcurrencyStrategy.READ_ONLY, region = "organization") public class Organizational implements CodedValue, Comparable<Organizational>, Serializable { private static final long serialVersionUID = 7414956278287853961L; @Id private String code; @Id private BusinessArea businessArea; private Organizational() { } .... }
public class OrganizationalKey implements Serializable { private static final long serialVersionUID = -8022957102173252455L; @ManyToOne(targetEntity = BusinessArea.class) @JoinColumn(name = "BUSINESS_AREA_CODE", insertable = false, updatable = false) private BusinessArea businessArea; @Column(name = "CODE", length = 5, insertable = false, updatable = false) private String code; OrganizationalKey() { } .... }
@Entity @Table(name = "VO_AREA") @Cache(usage = CacheConcurrencyStrategy.READ_ONLY, region = "organization") public class BusinessArea implements CodedValue, Serializable { private static final long serialVersionUID = 6911068689852530787L; @Id @Column(name = "BUS_ARA_IDR", length = 3, updatable = false) private String code; private BusinessArea() { }; }
