@Column(s) not allowed on a @ManyToOne property

问题:

I have a JPA entity with a property set as

@ManyToOne
@Column(name="LicenseeFK")
private Licensee licensee;

But when I deploy on JBoss 6 the application throws an error saying:

org.hibernate.AnnotationException: @Column(s) not allowed on a @ManyToOne property

I use Hibernate 3.5 as the JPA 2.0 implementation.

What should I use to reference the foreign key column?

回答1:

Use @JoinColumn instead of @Column:

@ManyToOne
@JoinColumn(name="LicenseeFK")
private Licensee licensee;

回答2:

Using @JoinColumn and @Column together will result in the same error. Change it to only use: @JoinColumn to fix it.
