Annotation Type JoinColumns

@Target(value={TYPE,METHOD,FIELD})
@Retention(value=RUNTIME)
public @interface JoinColumns

Defines mapping for the composite foreign keys. This annotation groups JoinColumn annotations for the same relationship.

When the JoinColumns annotation is used, both the name and the referencedColumnName elements must be specified in each such JoinColumn annotation.

    Example:
    @ManyToOne
    @JoinColumns({
        @JoinColumn(name="ADDR_ID", referencedColumnName="ID"),
        @JoinColumn(name="ADDR_ZIP", referencedColumnName="ZIP")
    })
    public Address getAddress() { return address; }
