Package javax.persistence
Annotation Interface JoinColumns
Defines mapping for 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; }
