我想实现输入字段验证。这是托管 bean 的代码:

这是我添加到 faces-config.xml 中的代码
<validator>
<validator-id>ValidatorController</validator-id>
<validator-class>com.DX_57.HM_57.FormValidator</validator-class>
</validator>
这是我尝试测试的验证器的代码:
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));
}
}
}
问题是我在尝试运行示例时遇到的这个错误:

看来 Validator 类不在正确的范围内。我必须使用什么范围?
最良好的祝愿
