Good afternoon, you can solve this problem using javascript as below:

<script type="text/javascript">
   function onlyNumbers(data){
      data.value = data.value.replace(/[^0-9]/g,'');
   };
</script>

And in the spinner use (you can change the timing of the call if you like, using another type of event):

<p:spinner id="spinnerBasic"  max="120" value="#{spinnerController.number1}" onkeyup="onlyNumbers(this)" />
