Scope in JSF Validator

I Voglio implementare la convalida del file input. Questo è il codice del bean gestito:Scope in JSF Validator

questo è il codice che ho aggiunto in faces-config.xml

<validator> 
    <validator-id>ValidatorController</validator-id> 
    <validator-class>com.DX_57.HM_57.FormValidator</validator-class> 
</validator>

questo è il codice del validatore che ho cercato di prova:

import javax.enterprise.context.SessionScoped; 
import javax.faces.application.FacesMessage; 
import javax.faces.component.UIComponent; 
import javax.faces.context.FacesContext; 
import javax.faces.validator.Validator; 
import javax.faces.validator.ValidatorException; 
import javax.inject.Named; 

@Named("ValidatorController") 
@SessionScoped 
public class FormValidator implements Validator { 

    public FormValidator() { 
    } 

    @Override 
    public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException { 
     throw new UnsupportedOperationException("Not supported yet."); 
    } 

    public void validateMessage(FacesContext context, UIComponent component, Object value) throws ValidatorException { 

     if (value.equals("test")) { 
      throw new ValidatorException(new FacesMessage(FacesMessage.SEVERITY_ERROR, 
        "Session ID is already in use, please choose another.", null)); 
     } 
    } 
}

il problema è questo errore che ottengo quando provo a fare funzionare l'esempio:

Sembra che la classe Validator non sia nell'ambito corretto. Quale ambito devo usare?

Auguri

Matt ha risposto al tuo pr attuale oblem, ma hai anche altri errori importanti nel validatore. Correggi il tuo validatore per far corrispondere esattamente l'esempio nella mia risposta alla tua domanda precedente. Dovresti svolgere il lavoro nel metodo 'validate()' dell'interfaccia 'Validator', non in un metodo personalizzato. Non dovresti aver bisogno della vecchia JSF 1.x '' dichiarazione in 'faces-config.xml'. Si dovrebbe fare riferimento all'istanza del validatore concreto in 'binding', non solo al suo metodo. – BalusC

Ok, ma se rimuovo la dichiarazione in faces-config.xml posso usare CDI nel validatore? Voglio implementare un validatore personalizzato perché se ho 20 campi di input devo implementare 20 validatori standard in diverse classi e file Java. Voglio farlo in un file. –

È possibile? –

prova di questo codice:

<h:panelGroup>Session ID</h:panelGroup> 
<h:panelGroup> 
    <h:inputText id="sessionid" value="#{DatabaseController.formMap['sessionid']}" 
        validator="#{ValidatorController.validatebean}">           
     <f:ajax event="blur" render="sessionidMessage" />           
    </h:inputText> 
    <h:message id="sessionidMessage" for="sessionid" /> 
</h:panelGroup>

Questo è il fagiolo:

@Named("ValidatorController") 
@ViewScoped 
public class FormValidator implements Validator { 

    public FormValidator() { 
    } 

    @Override 
    public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException { 
     if (value.equals("test")) { 
      throw new ValidatorException(new FacesMessage(FacesMessage.SEVERITY_ERROR, 
        " Session ID is already in use, please choose another.", null)); 
     } 
    } 

    public void validatebean(FacesContext context, UIComponent component, Object value) throws ValidatorException { 
     if (value.equals("test")) { 
      throw new ValidatorException(new FacesMessage(FacesMessage.SEVERITY_ERROR, 
        " Session ID is already in use, please choose another.", null)); 
     } 
    } 

}

Wow, non so perché e come, ma questo codice funziona! Grazie a tutti! –

Dalla documentazione WELD:

fagioli gestiti con portata @SessionScoped o @ConversationScoped devono essere serializzabile, dal momento che il contenitore passivare la sessione HTTP da volta in volta.

Ci potrebbero essere altre ragioni, ma la sessione CDI con ambito di fagioli dovrebbe almeno implementare l'interfaccia Serializable:

@Named("ValidatorController") 
@SessionScoped 
public class FormValidator implements Validator, Serializable { 
... 
}
