I need help with composite primary keys
This example always give the exception below.
package pt.giss.siss.persistence;
import java.io.Serializable;
import javax.persistence.Embeddable;
import javax.persistence.EmbeddedId;
import javax.persistence.Entity;
@Entity
public class Entity1 {
private int attribute;
private Entity1PK pk;
public int getAttribute() { return attribute; }
public void setAttribute(int attribute) { this.attribute = attribute; }
@EmbeddedId
public Entity1PK getPk() { return pk; }
public void setPk(Entity1PK pk) { this.pk = pk; }
}
@Embeddable
class Entity1PK implements Serializable {
private String attr1;
private String attr2;
public Entity1PK() {}
public boolean equals(Object obj) {
return true;
}
public int hashCode() {
return attr1.hashCode() + attr2.hashCode();
}
}
