validation - 如何自定义JSF验证错误消息

Question

如何自定义验证失败时出现的验证消息？

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>

当前消息看起来像这样:

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

这不是特别用户友好。

最简单的方法是在validatorMessage="my custom message"标记中设置<h:inputText>属性。
