Hi, I tried following thing:
@MappedSuperclass
| @IdClass(FootballerPk.class)
| public class Footballer {
| String firstname;
| String lastname;
| //part of the id key
| @Id public String getFirstname() {
| return firstname;
| }
|
| public void setFirstname(String firstname) {
| this.firstname = firstname;
| }
|
| //part of the id key
| @Id public String getLastname() {
| return lastname;
| }
|
| public void setLastname(String lastname) {
| this.lastname = lastname;
| }
|
| public String getClub() {
| return club;
| }
|
| public void setClub(String club) {
| this.club = club;
| }
|
| //appropriate equals() and hashCode() implementation
| }
|
| @Embeddable
| public class FootballerPk implements Serializable {
| String firstname;
| String lastname;
| //same name and type as in Footballer
| public String getFirstname() {
| return firstname;
| }
|
| public void setFirstname(String firstname) {
| this.firstname = firstname;
| }
|
| //same name and type as in Footballer
| public String getLastname() {
| return lastname;
| }
|
| public void setLastname(String lastname) {
| this.lastname = lastname;
| }
|
| //appropriate equals() and hashCode() implementation
| }
@Entity
| @AttributeOverride( name="firstname", column =
@Column(name="new_firstname") )
| public class ExtendedFootballer extends Footballer{
| ...
| }
But I dont get it to work, that the Attrribute is overwritten.
All works fine if I dont use @IdClass.
Is this a possible Bug?
