大家好我是java EE的新手，我想开发一个带有EJB和JSF的应用程序，当我想在web dynamique项目中注入我的JAR时，我有这个错误而且我什么都不懂，请任何人都可以帮助我

}
这是DAO接口：
package com.bestofgeeks.gestion.dao;
import java.util.List;
import javax.ejb.Local;
import com.bestofgeeks.gestion.entity.products;
@Local
public interface IGestion {
public void delete(products p);
public products persiste(products p);
public List<products> selectAll();
}
接口DAO
package com.bestofgeeks.gestion.dao;
import java.util.List;
import javax.ejb.Local;
import com.bestofgeeks.gestion.entity.products;
@Local
public interface IGestion {
public void delete(products p);
public products persiste(products p);
public List<products> selectAll();
}
实施DAO
package com.bestofgeeks.gestion.dao.Implement;
import java.util.List;
import javax.ejb.Stateless;
import javax.management.Query;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import com.bestofgeeks.gestion.dao.IGestion;
import com.bestofgeeks.gestion.entity.products;
@Stateless
public class GestionDAOBean implements IGestion{
@PersistenceContext(unitName = "Gestion_PU")
EntityManager entityManager;
@Override
public void delete(products p) {
// TODO Auto-generated method stub
entityManager.remove(p);
}
@Override
public products persiste(products p){
// TODO Auto-generated method stub
entityManager.persist(p);
return p;
}
@Override
public List<products> selectAll() {
// TODO Auto-generated method stub
Query query = (Query) entityManager.createQuery("SELECT o from products o");
return ((javax.persistence.Query) query).getResultList();
}
}
这是我项目的包服务 此服务具有接口Iservice和实现类名称ImplServiceProduct的包 对于Iservice，这是代码
package com.bestofgeeks.gestion.services;
import java.util.List;
import javax.ejb.Local;
import com.bestofgeeks.gestion.entity.products;
@Local
public interface Iservices {
public List<products> selectAll();
public void delete(products p);
public products persiste(products p);
}
用于实施服务
package com.bestofgeeks.gestion.services.ImplService;
import java.util.List;
import javax.ejb.EJB;
import javax.ejb.Stateless;
import com.bestofgeeks.gestion.dao.Implement.GestionDAOBean;
import com.bestofgeeks.gestion.entity.products;
import com.bestofgeeks.gestion.services.Iservices;
@Stateless
public class ImplServiceProduct implements Iservices{
@EJB
GestionDAOBean product;
@Override
public List<products> selectAll() {
return product.selectAll();
}
@Override
public void delete(products p) {
// TODO Auto-generated method stub
product.delete(p);
}
@Override
public products persiste(products p) {
// TODO Auto-generated method stub
return product.persiste(p);
}
}
为实体
package com.bestofgeeks.gestion.entity;
import java.util.Date;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table
public class products {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private Long id;
@Column
private String nameproduct;
@Column
private String reference;
@Column
private Date dateposte;
public products(String nameproduct, String reference, Date dateposte) {
super();
this.nameproduct = nameproduct;
this.reference = reference;
this.dateposte = dateposte;
}
public products() {
super();
// TODO Auto-generated constructor stub
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getNameproduct() {
return nameproduct;
}
public void setNameproduct(String nameproduct) {
this.nameproduct = nameproduct;
}
public String getRefence() {
return reference;
}
public void setRefences(String reference) {
this.reference = reference;
}
public Date getDateposte() {
return dateposte;
}
public void setDateposte(Date dateposte) {
this.dateposte = dateposte;
}
}
和我的jsf项目 我创建了一个控制器 这是代码
package com.bestofgeeks.gestion.controllers;
import javax.annotation.ManagedBean;
import javax.ejb.EJB;
import javax.enterprise.context.RequestScoped;
import com.bestofgeeks.gestion.services.Iservices;
@RequestScoped @ManagedBean
public class myProduct {
@EJB
public String name = "noredine";
Iservices service;
}
答案 0 :(得分：2)
您必须注入本地接口而不是bean：
@EJB
IGestion product;
正如@kukeltje在评论中所说：
阅读错误:(强调我的）＆＃34;找不到带有类型接口的EJB ＆＃39; com.bestofgeeks.gestion.dao.Implement.GestionDAOBean＆＃34;什么呢 引用是一个impl，而不是
界面！
