如何自定义JSF验证错误消息

How can I customize the validation message that appears when validation fails?

如何自定义验证失败时出现的验证消息？

Here is the code I have:

这是我的代码：

<h:form>
    <p><h:inputText
           id="userNo"
           title="Type a number from 0 to 10:">
       <f:validateLongRange
           minimum="3"
           maximum="6"/>
       </h:inputText>

       <h:commandButton id="submit" value="Submit"
           action="response"/>
    </p>
    <h:message showSummary="true" showDetail="false"
        id="errors1"
        for="userNo"/>
</h:form>

Currently the message looks like this:

目前消息如下所示：

j_idt10:userNo: Validation Error: Specified attribute is not between the expected values of 3 and 6.

Which is not particularly user-friendly.

哪个不是特别用户友好。

The simplest way would be to set the validatorMessage="my custom message" attribute in the <h:inputText> tag.

最简单的方法是在标记中设置validatorMessage =“我的自定义消息”属性。：inputtext>

In addition to Daniel's answer you could always use the label attribute for your input components to remove the client-id (j_idt10:userNo:) from the error message.

除了Daniel的答案之外，你总是可以使用输入组件的label属性从错误消息中删除client-id（j_idt10：userNo :)。

E.g. with

例如。同

<h:inputText id="userNo" title="Type a number from 0 to 10:"
             label="User number">
  <f:validateLongRange
           minimum="3"
           maximum="6"/>
</h:inputText>

will produce:

将产生：

User number: Validation Error: Specified attribute is not between the expected values of 3 and 6.

用户编号：验证错误：指定的属性不在预期值3和6之间。

The label attribute can be an el expression as well to change this part of the error message dynamically.

label属性也可以是el表达式，以动态更改错误消息的这一部分。

You can use validatorMessage property of input text. Use requiredMessage property for required message, it is different from validator message.

您可以使用输入文本的validatorMessage属性。对所需消息使用requiredMessage属性，它与验证器消息不同。

<h:input text required ="true" validatorMessage="Enter user friendly message">
    <f:validateLongRange
        minimum="3"
        maximum="6"/>
</h:inputText>
