Hello,
I've tried to implement composite pattern with EJB3, but it seems impossible.
This is my code :
1- parent class
| @Entity
| @Table(name = "groupesetediteurs")
| @Inheritance(strategy = InheritanceType.JOINED)
| public abstract class EGroupesEtEditeurs
| implements Serializable {
| protected boolean isroot = false;
| private String nom = null;
|
|
| private List<EGroupesEtEditeurs> groupesEtEditeurs = new
ArrayList<EGroupesEtEditeurs>();
|
| private int id;
|
| @Id(generate = GeneratorType.AUTO)
| public int getId() {
| return id;
| }
|
|
|
| public void setId(int id) {
| this.id = id;
| }
|
|
| public void add(EGroupesEtEditeurs ge) {
| this.groupesEtEditeurs.add(ge);
| }
|
| public void del(EGroupesEtEditeurs ge) throws Exception {
| this.groupesEtEditeurs.remove(ge);
| }
|
| public void setNom(String nom){
| this.nom = nom;
| }
|
| private void setRoot(boolean isroot) {
| this.isroot = isroot;
| }
|
|
| public String getNom() {
| return nom;
| }
|
|
| @OneToMany(cascade=CascadeType.ALL, fetch=FetchType.EAGER)
| @JoinTable(
| [EMAIL PROTECTED](name="GroupesEditeurs"),
| joinColumns = { @JoinColumn( name="parent_id") },
| inverseJoinColumns = @JoinColumn( name="enfant_id")
| )
| public List<EGroupesEtEditeurs> getGroupesEtEditeurs(){
| return groupesEtEditeurs;
| }
|
|
|
| private void setGroupesEtEditeurs(List<EGroupesEtEditeurs>
groupesEtEditeurs) {
| this.groupesEtEditeurs = groupesEtEditeurs;
| }
|
|
| public boolean isRoot() {
| return isroot;
| }
|
| }
|
2- node class
| @Entity
| @Table(name = "groupedepresse")
| public class EGroupeDePresse extends EGroupesEtEditeurs {
|
| public EGroupeDePresse() {}
|
|
| public EGroupeDePresse(String nom) throws Exception {
| this.setNom(nom);
| }
|
|
| public void add(EGroupesEtEditeurs ge) throws Exception {
| super.add(ge);
| }
|
| public void del(EGroupesEtEditeurs ge) throws Exception {
| super.del(ge);
| }
|
| public void setNom(String nom){
| super.setNom(nom);
| }
|
|
|
| public String getNom() {
| return super.getNom();
| }
|
|
| public List<EGroupesEtEditeurs> getGroupesEtEditeurs(){
| return super.getGroupesEtEditeurs();
| }
|
| public void makeRoot(){
| this.isroot = true;
| }
|
| public boolean isRoot() {
| return super.isroot;
| }
|
|
| }
|
3- Leaf class
| @Entity
| @Table(name = "editeur")
| public class EEditeur extends EGroupesEtEditeurs implements Serializable{
|
| private List<ETitre> titres = new ArrayList<ETitre>();
| private ArrayList interlocuteurs = new ArrayList();
|
| public EEditeur() {}
|
|
| public EEditeur(String nom) throws Exception {
| this.setNom(nom);
| }
|
|
| public void add(EGroupesEtEditeurs ge) throws Exception {
| throw new Exception(
| "Un Editeur ne peut pas posséder de Groupes ou d'Editeurs");
| }
|
|
| public void del(EGroupesEtEditeurs ge) throws Exception {
| throw new Exception(
| "Un Editeur ne peut pas posséder de Groupes ou d'Editeurs");
| }
|
|
| public String getNom() {
| return super.getNom();
| }
|
|
| public void setNom(String nom){
| super.setNom(nom);
| }
|
|
| public List<EGroupesEtEditeurs> getGroupesEtEditeurs(){
| return super.getGroupesEtEditeurs();
| }
|
| public boolean isRoot() {
| return false;
| }
|
| @OneToMany(cascade=CascadeType.ALL, fetch=FetchType.EAGER)
| @JoinTable(
| [EMAIL PROTECTED](name="EditeurTitres"),
| joinColumns = { @JoinColumn( name="editeur_id") },
| inverseJoinColumns = @JoinColumn( name="titre_id")
| )
| public List<ETitre> getTitres() {
| return titres;
| }
|
|
| public void setTitres(List<ETitre> titres) {
| this.titres = titres;
| }
|
| public void addTitre(ETitre titre) {
| //ETitre.validation(titre);
| this.titres.add(titre);
| }
|
| public void delTitre(ETitre titre) {
| this.titres.remove(titre);
| }
|
|
| }
|
|
