Hey,
I have a composite key to user table.
so i have class for the composite-id - UserID (first,second)
I have class XXX like this:
1- the same pk like user
2- many to one to user.
in the many-to-one to the user i use in joincolumns like this:
@JoinColumns( { @JoinColumn(name = "first",referencedColumnName="first",
@JoinColumn(name = "second",referencedColumnName="second") })
i get an exception:
repeated column for column- first
The same clumns are the PK and FK.
Can you please advice.
@Entity
| public class Animal {
| @EmbeddedId PK pk = new PK();
| @ManyToOne
| @JoinColumns( { @JoinColumn(name = "first",referencedColumnName="first"),
@JoinColumn(name = "second",referencedColumnName="second") })
| Owner owner;
| }
|
| @Entity
| public class Owner {
| @EmbeddedId PK pk = new PK();
| }
|
| public class PK implements Serializable{
| public String first;
| public String second;
| }
