Issue
I need a field to be part of the composite key, but I also need a Many to one relationship with the corresponding object. Is something like this possible ?
@Entity
public class Instrument {
@EmbeddedId
private InstrumentPk instrumentPk;
@ManyToOne;
private Transaction transaction;
}
@Embeddable
public class InstrumentPk {
private Integer productId;
private Integer transId;
}
Solution
In your case @ManyToOne relationship has nothing to do with @Embeddable:
@ManyToOne;
private Transaction transaction;
This is goig to work just fine provided there is a Transaction entity and mapping is well defined.
