java - Using JSTL url and param tag -

-

i have list of sizes user can choose from, posssible build parameter based on link user clicks?

for example, there following html

    <ul class="options list-unstyled">                 <h4 class="m_9">select size</h4>                 <li><a href="?size=s">s</a></li>                 <li><a href="?size=m">m</a></li>                 <li><a href="?size=l">l</a></li>                 <li><a href="?size=xl">xl</a></li>                 <div class="clearfix"></div>                 </ul>

and there in controller

 @requestmapping(value = "/addprodtocart", method = requestmethod.post) public modelandview cart(@requestparam("productid") integer id, @requestparam("size") string size) {}

disregarding productid size requestparam equal ever 1 user clicked. temp variable in jstl changes whenever new size selected , form below passed built url (basically whichever size user selected)

 <form  method='post' action="${url }" >                  <input type="hidden" name="${_csrf.parametername}" value="${_csrf.token}"/>                    <input type="submit" value="add cart" title="">               </form>

is possible? , how? thank
