在我的项目中，我想显示数据库中的记录。我使用的数据库是带有SQL Developer的Oracle Thin（Oracle 11g）。当我的页面使用控制器调用初始化时，我遇到了这个错误：
WELD-000049：无法在controller.EvenementController@32e0c910上调用public void controller.EvenementController.initialize（）
我使用像IDE这样的Netbeans。这是我的代码，控制器，dao，我的类+堆栈跟踪：
控制器
@Named(value="evenementController")
@RequestScoped
public class EvenementController
{
@Inject
private IEvenementServ evenementService;
private Evenement event;
private List<Evenement> evenements;
public Evenement getEvent() {
return event;
}
@PostConstruct
public void initialize(){
event = evenementService.getEvenement("E01");
}
public List<Evenement> getEvenements() {
return evenements;
}
}
DAO
@Default
@ApplicationScoped
public class EvenementService implements IEvenementService
{
private Session currentSession;
private Transaction currentTransaction;
@Override
public BcEvenement getEvenement(String pkCode) {
Evenement evenement = new Evenement();
try{
this.currentSession = HibernateUtil.getSessionFactory().openSession();
evenement = (BcEvenement)currentSession.get(Evenement.class, pkCode);
}catch(HibernateException e){
//e.printStackTrace();
}finally{
//this.currentSession.close();
}
return evenement;
}
Evenement JavaClass
public class BcEvenement implements java.io.Serializable {
private String pkCode;
private String nom;
private String imgSrc;
public BcEvenement() {
}
public BcEvenement(String pkCode, String nom) {
this.pkCode = pkCode;
this.nom = nom;
}
public BcEvenement(String pkCode, String nom, String imgSrc) {
this.pkCode = pkCode;
this.nom = nom;
this.imgSrc = imgSrc;
}
// + all GET / SET for all this attribute
在我的索引页面上，我称之为：
<h2>#{evenementController.event.imgSrc}</h2>

在构建路径上添加ojdbc14.jar它将起作用。
