springMVC實現人氣，價格排序

1，前臺 

<a th:href="@{initGoodsByPopularDesc(commodityTypeId=${goodsForm.commodityTypeId})}" th:class="${orderTypeId}==3?'btn btn-default btn-danger':'btn btn-default'" th:if="${orderTypeId}!=2">&nbsp;人&nbsp;氣<i></i>&nbsp;</a>

 <a th:href="@{initGoodsByPopular(commodityTypeId=${goodsForm.commodityTypeId})}" th:class="${orderTypeId}==2?'btn btn-default btn-danger':'btn btn-default'" th:if="${orderTypeId}==2">&nbsp;人&nbsp;氣<i class="up"></i>&nbsp;</a>

 <a th:href="@{initGoodsByPriceDesc(commodityTypeId=${goodsForm.commodityTypeId})}" th:class="${orderTypeId}==5?'btn btn-default btn-danger':'btn btn-default'" th:if="${orderTypeId}!=4">&nbsp;價&nbsp;格<i></i>&nbsp;</a>

 <a th:href="@{initGoodsByPrice(commodityTypeId=${goodsForm.commodityTypeId})}" th:class="${orderTypeId}==4?'btn btn-default btn-danger':'btn btn-default'" th:if="${orderTypeId}==4">&nbsp;價&nbsp;格<i class="up"></i>&nbsp;</a>
