未指定验证程序标识

Question

我根据JSF 2规范注册了一个Validator：

@FacesValidator(value = "emailValidator")
public class EmailValidator implements Validator {..}

用法：

<h:inputText value=#{bean.email}>
<f:validator id="emailValidator" />
</h:inputText>

我得到了这个例外：

javax.servlet.ServletException: /contact.xhtml @21,130 <f:validator> A validator id was not specified. Typically the validator id is set in the constructor ValidateHandler(ValidatorConfig)
javax.faces.webapp.FacesServlet.service(FacesServlet.java:606)
org.jboss.weld.servlet.ConversationPropagationFilter.doFilter(ConversationPropagationFilter.java:62)
myapp.FilterLogout.doFilter(FilterLogout.java:83)

这是一个错误吗？

Answer 1

试试这个

@FacesValidator(value="emailValidator")
public class EmailValidator implements Validator {
 @override
     public void validate(FacesContext context, UIComponent component,
        Object value) throws ValidatorException {
     }
 }

在xhtml中，你有

           <h:inputText value=#{bean.email}>
             <f:validator validatorId="emailValidator" />
           </h:inputText>
