验证器类：

@FacesValidator("br.gov.valec.sicpd.util.CpfValidator")
public class CpfValidator implements Validator {

    @Override
    public void validate(FacesContext context, UIComponent component, Object value)
        throws ValidatorException {
        if (validateCpf(value.toString())) {
            FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_ERROR,"Invalid Input","Invalid Input");
            ((UIInput) component).setValid(false); // this line doesnt work

        throw new ValidatorException(msg);
    }
}

JSF片段：

JSF snippet:

<p:inputText label="CPF" id="inputCpf"
                    value="#{mainBean.owner.cpf}">
                    <f:validator validatorId="br.gov.valec.sicpd.util.CpfValidator" />
                    <p:ajax event="change" update="inputNameOwner"
                        listener="#{mainBean.searchOwner}"  />
</p:inputText>

当表单通过命令按钮primefaces提交自动突出显示它。我怎样才能做到这一点，当阿贾克斯被触发并且验证失败？

When the form is submitted via command button primefaces highlights it automatically. How can I achieve that when ajax is fired and validation fails?

推荐答案

在 UIInput＃setValid（假）工作正常。你刚才忘记告诉Ajax来更新输入组件本身。添加 inputCpf 或 @this 到＆LT;电话号码：AJAX更新＆GT; 。

The UIInput#setValid(false) is working fine. You just forgot to tell ajax to update the input component itself. Add inputCpf or @this to <p:ajax update>.

<p:ajax ... update="@this inputNameOwner" />

在校验明确 UIInput＃setValid（假）呼叫的方式是不必要的。摆脱它。一旦抓到的JSF已经做了一切本身的 ValidatorException 抛出您的验证。

That explicit UIInput#setValid(false) call in validator is by the way unnecessary. Get rid of it. JSF already does it all by itself once it catches the ValidatorException thrown by your validator.
