JSF 2.0 validateRegex 带有自己的验证器消息

发布于 2024-12-04 06:57:08 字数 702 浏览 1 评论 0原文

我有一个与此类似的代码：

<h:inputText id="email" value="#{managePasswordBean.forgotPasswordEmail}"
        validatorMessage="#{validate['constraints.email.notValidMessage']}"
        requiredMessage="#{validate['constraints.email.emptyMessage']}"
        validator="#{managePasswordBean.validateForgotPasswordEmail}"
        required="true">
    <f:validateRegex pattern="^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,6})$" />
</h:inputText>

支持 bean 中的验证器生成了自己的验证消息。但它被 inputText 标签的 validatorMessage 覆盖。

我的问题是：如何为 validateRegex 标记定义自定义验证器消息？我不想删除 validatorMessage 因为 JSF 会显示一条自己的错误消息，其中包含正则表达式模式等 ->我觉得不太漂亮。

感谢您的帮助:)

i am having a code similar to this:

<h:inputText id="email" value="#{managePasswordBean.forgotPasswordEmail}"
        validatorMessage="#{validate['constraints.email.notValidMessage']}"
        requiredMessage="#{validate['constraints.email.emptyMessage']}"
        validator="#{managePasswordBean.validateForgotPasswordEmail}"
        required="true">
    <f:validateRegex pattern="^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,6})$" />
</h:inputText>

The validator in the backing bean has its own validation message generated. but it is overwritten by the validatorMessage of the inputText tag.

My Question is: how can i define a custom validator message for the validateRegex tag? I don't want to remove the validatorMessage cause then JSF is displaying an own error message containing the regex pattern and so on -> which i dont find very pretty.

Thanks for the help :)

您无法为每个单独的验证器定义单独的 validatorMessage。您能做的最好的事情就是在自定义验证器中进行正则表达式验证，以便您可以删除 validatorMessage。

更新：自版本 1.3 起，< /code>JSF 实用程序库的组件 OmniFaces 允许您设置基于每个验证器的验证器消息。然后，您的具体情况可以按如下方式解决：

<h:inputText id="email" value="#{managePasswordBean.forgotPasswordEmail}"
        required="true" requiredMessage="#{validate['constraints.email.emptyMessage']}">
    <o:validator binding="#{managePasswordBean.validateForgotPasswordEmail}" message="#{validate['constraints.email.notValidMessage']}" />
    <o:validator validatorId="javax.faces.RegularExpression" pattern="^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,6})$" message="Your new custom message here" />
</h:inputText>

与具体问题无关：如今，只要您仍然根据以下内容验证电子邮件地址，您就没有准备好统治世界拉丁字符。另请参阅在 JSF 2 中使用正则表达式进行电子邮件验证/ PrimeFaces。

You can't define a separate validatorMessage for each individual validator. Best what you can do is to do the regex validation in your custom validator as well, so that you can remove the validatorMessage.

Update: since version 1.3, the <o:validator> component of the JSF utility library OmniFaces allows you to set the validator message on a per-validator basis. Your particular case can then be solved as follows:

<h:inputText id="email" value="#{managePasswordBean.forgotPasswordEmail}"
        required="true" requiredMessage="#{validate['constraints.email.emptyMessage']}">
    <o:validator binding="#{managePasswordBean.validateForgotPasswordEmail}" message="#{validate['constraints.email.notValidMessage']}" />
    <o:validator validatorId="javax.faces.RegularExpression" pattern="^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,6})$" message="Your new custom message here" />
</h:inputText>

Unrelated to the concrete problem: these days you would be not ready for world domination as long as you still validate email addresses based on Latin characters. See also Email validation using regular expression in JSF 2 / PrimeFaces.

这对我有用。
您可以在“validatorMessage”中编写自定义消息

 <h:form id="form">
        <h:outputLabel for="name">Name :</h:outputLabel>  
        <h:inputText id="name" value="#{editStock.name}" required="true" requiredMessage="Name field must not be empty" validatorMessage="Your name can have only Alphabets">  
        <f:validateRegex pattern="^[a-zA-Z]*$" />  
        </h:inputText><br/>  
        <h:message for="name" style="color:red" />
        <h:commandButton value="Update" action="#{stock.update(editStock)}" style="width: 80px;"></h:commandButton> 
 </h:form>

This worked for me.
You can write your custom messages in "validatorMessage"

 <h:form id="form">
        <h:outputLabel for="name">Name :</h:outputLabel>  
        <h:inputText id="name" value="#{editStock.name}" required="true" requiredMessage="Name field must not be empty" validatorMessage="Your name can have only Alphabets">  
        <f:validateRegex pattern="^[a-zA-Z]*quot; />  
        </h:inputText><br/>  
        <h:message for="name" style="color:red" />
        <h:commandButton value="Update" action="#{stock.update(editStock)}" style="width: 80px;"></h:commandButton> 
 </h:form>
