无法解析引用本地ejb-ref(Cannot resolve reference Local ejb-ref)
java
我在编写EJB应用程序时遇到了问题。 我搜索一个解决方案，但我仍然在使用Glassfish4的intelliJ中遇到同样的问题：“无法解析引用[Local ejb-ref name = EJB.AdminEJB，Local 3.x interface = Interface.AdminInterface，ejb-link = null，lookup =， mappedName =，jndi-name =，refType = Session]因为应用程序中有[2] ejbs，接口为Interface.AdminInterface。“ 请原谅我的英语，我是法国人。
包接口中的AdminInterface
@Local public interface AdminInterface { public void creerParieur(Parieur parieur); public void supprimerParieur (String login); public void creerBookmaker(Bookmaker bookmaker); public void supprimerBookmaker (String login); public void modifParieur (Parieur parieur); public void modifBookmaker (Bookmaker bookmaker); public void ajouterCote(Cote cote); public void ajouterMatch (Match match); public List<Cote> listeCote(String log); public List<Match> listeMatch(); public List<Parieur> listeParieur(); public List<Bookmaker> listeBookmaker(); public Parieur rechercheParieur(String id); public Bookmaker rechercheBookmaker (String id); public void setLogin(String login); public String getLogin();}
程序包EJB中的AdminEJB
@Stateless public class AdminEJB implements AdminInterface{ String login; String mdp; @PersistenceContext(unitName = "NewPersistenceUnit") EntityManager em; public AdminEJB(){} public String getLogin(){ return login; } public void setLogin(String login){ this.login=login; } public String getMdp(){ return mdp; } public void setMdp(String mdp){ this.mdp=mdp; } public void creerParieur(Parieur parieur){ em.persist(parieur); } public void supprimerParieur(String login){ Parieur parieur=new Parieur (); Query req=em.createQuery("select OBJECT(P) from Parieur P where P.login=:login"); req.setParameter("login", login); parieur=(Parieur)req.getSingleResult(); em.remove(parieur); } public void modifParieur(Parieur parieur){ em.merge(parieur); } public List<Parieur> listeParieur(){ Query req=em.createQuery("select OBJECT(P) from Parieur P"); return req.getResultList(); } public void creerBookmaker(Bookmaker bookmaker){ em.persist(bookmaker); } public void supprimerBookmaker(String login){ Bookmaker bookmaker; Query req=em.createQuery("select OBJECT(B) from Bookmaker B where B.pseudo=:login"); req.setParameter("login", login); bookmaker=(Bookmaker)req.getSingleResult(); em.remove(bookmaker); } public void modifBookmaker(Bookmaker bookmaker){ em.merge(bookmaker); } public List<Bookmaker> listeBookmaker(){ Query req=em.createQuery("select OBJECT(B) from Bookmaker B"); return req.getResultList(); } public List<Match> listeMatch(){ Query req=em.createQuery("select OBJECT(M) from Match M"); return req.getResultList(); } public Bookmaker rechercheBookmaker(String id){ return em.find(Bookmaker.class,id); } public Parieur rechercheParieur(String id){ return em.find(Parieur.class,id); } public void ajouterCote (Cote cote){ em.persist(cote); } public void ajouterMatch (Match match){ em.persist(match); } public List<Cote> listeCote(String log){ Bookmaker bookmaker = new Bookmaker(); bookmaker = this.rechercheBookmaker(log); Query req = em.createQuery("select OBJECT(C) from Cote C where C.bookmaker=:bookmaker"); req.setParameter("bookmaker", bookmaker); return req.getResultList(); }}
在ManagedBean包中的ControlerBean
@ManagedBean @RequestScoped public class ControlerBean implements Serializable{ Bookmaker bookmaker; Pari pari; Parieur parieur; Match match; Cote cote; String nomObjetP; String nomEnP; String pseudoUser; String pwdUser; @EJB private AdminInterface admin; public ControlerBean(){ bookmaker = new Bookmaker(); parieur = new Parieur(); cote = new Cote(); match= new Match(); pari= new Pari(); } public String getNomObjetP() { return nomObjetP; } public void setNomObjetP(String nomObjetP) { this.nomObjetP = nomObjetP; } public String getNomEnP() { return nomEnP; } public void setNomEnP(String nomEnP) { this.nomEnP = nomEnP; } public Pari getPari() { return pari; } public void setPari(Pari pari){ this.pari=pari; } public Bookmaker getBookmaker() { return bookmaker; } public void setBookmaker(Bookmaker bookmaker) { this.bookmaker = bookmaker; } public Parieur getParieur() { return parieur; } public void setParieur(Parieur parieur) { this.parieur = parieur; } public Cote getCote() { return cote; } public void setCote(Cote cote) { this.cote = cote; } public Match getMatch(){ return match; } public void setMatch(Match match){ this.match=match; } public AdminInterface getAdmin() { return admin; } public void setAdmin(AdminInterface admin) { this.admin = admin; } public String getPseudoUser() { return pseudoUser; } public void setPseudoUser(String pseudoUser) { this.pseudoUser = pseudoUser; } public String getPwdUser() { return pwdUser; } public void setPwdUser(String pwdUser) { this.pwdUser = pwdUser; } public String addParieur(){ parieur.setArgent(1000); admin.creerParieur(parieur); return "OK"; } public String modifParieur(){ admin.modifParieur(parieur); return "OK"; } public String supprParieur(){ admin.supprimerParieur(parieur.getLogin()); return "OK"; } public String addBookmaker(){ admin.creerBookmaker(bookmaker); return "OK"; } public String modifBookmaker(){ admin.modifBookmaker(bookmaker); return "OK"; } public String supprBookmaker(){ admin.supprimerBookmaker(bookmaker.getPseudo()); return "OK"; } public List<Bookmaker> listeBookmaker(){ return admin.listeBookmaker(); } public List<Parieur> listeParieur(){ return admin.listeParieur(); } public List<Match> listeMatch(){ return admin.listeMatch(); } public String addCote(){ pseudoUser = admin.getLogin(); cote.setBookmaker(admin.rechercheBookmaker(pseudoUser)); admin.ajouterCote(cote); return "OK"; } public String addMatch(){ admin.ajouterMatch(getMatch()); return "OK"; }}
非常感谢您的帮助
I have an issue in programming an EJB application. I search a solution but I still have the same problem in intelliJ with Glassfish4 : " Cannot resolve reference [Local ejb-ref name=EJB.AdminEJB,Local 3.x interface =Interface.AdminInterface,ejb-link=null,lookup=,mappedName=,jndi-name=,refType=Session] because there are [2] ejbs in the application with interface Interface.AdminInterface." And excuse-me for my english, I'm french.

Thank's very much for any help

如果有两个EJB实现相同的接口，则需要对它们进行区分，以便容器知道要注入哪个EJB。
将@Stateless注释中的name参数添加到实现相同接口的所有bean。 在@EJB注释中，使用beanName参数注入适当的会话bean实现。
@Stateless(name="AdminEJB1") public class AdminEJB implements AdminInterface { .... } @EJB(beanName = "AdminEJB1") private AdminInterface myAdminEjb;您还可以跳过@Stateless注释中的name参数，然后使用实现类的名称作为@EJB注释中的beanName参数。
@Stateless public class AdminEJB implements AdminInterface { .... } @EJB(beanName = "AdminEJB") private AdminInterface myAdminEjb;When you have two EJBs implementing the same interface they need to be differentiated so that the container knows which one to inject.
Add the name parameter in the @Stateless annotation to all beans implementing the same interface. In the @EJB annotation, use the beanName parameter to inject the appropriate session bean implementation.
@Stateless(name="AdminEJB1") public class AdminEJB implements AdminInterface { .... } @EJB(beanName = "AdminEJB1") private AdminInterface myAdminEjb;You can also skip the name parameter in the @Stateless annotation and then use the name of the implementing class as the beanName parameter in the @EJB annotation.
@Stateless public class AdminEJB implements AdminInterface { .... } @EJB(beanName = "AdminEJB") private AdminInterface myAdminEjb;更多推荐
