我我想要實現輸入驗證申請。這是被管理的bean的代碼：範圍在JSF驗證

這是我加入faces-config.xml中
<validator>
<validator-id>ValidatorController</validator-id>
<validator-class>com.DX_57.HM_57.FormValidator</validator-class>
</validator>
這是我試圖測試確認者的代碼的代碼：
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));
}
}
}
問題是這樣的錯誤，我得到的，當我嘗試運行例如：

看來，Validator類是不正確的範圍。我必須使用什麼範圍？
祝福
馬特已經回答了你當前的PR但是你在驗證器中還有其他的重大錯誤。修正您的驗證器，以便與您在上一個問題的答案中的示例完全匹配。您應該在'Validate'接口的validate（）'方法中完成這項工作，而不是自定義方法。你不應該需要在'面孔，config.xml'老JSF 1.x的''聲明。你應該在'binding'中引用具體的validator實例，而不僅僅是它的方法。 –

好了，但如果我刪除faces-config.xml中聲明我可以使用CDI進入驗證？我想實現自定義驗證器，因爲如果我有20個輸入字段，我必須在不同的Java類和文件中實現20個標準驗證器。我想在一個文件中完成它。 –
這可能嗎？ –
