f:validateLongRange
<h:inputText value="#{userRegister.age }" required="true" id="Age">
<f:validateLongRange minimum="1" maximum="150"></f:validateLongRange> <!-- 年龄在1到150之间 -->
</h:inputText>
<h:message for="Age"></h:message>
?
f:validateDoubleRange
<h:inputText value="#{userRegister.height }" required="true" id="Height">
