thymeleaf中分类信息使用不同的样式

需求：

相关class类名:S224_on_point

url:/notification/list

 url:/notification/list?type=2

thymeleaf代码如下:

<div th:classappend="${(param.isEmpty() ? 'S224_on_point ' : '') + 'S224_message_kind pageChange'}" th:attr="data-page=@{/notification/list}">全部消息</div>
                <div th:classappend="${(#strings.equals(#request.getParameter('type'),'1') ? 'S224_on_point ' : '') + 'S224_message_kind pageChange'}" th:attr="data-page=@{/notification/list(type=1)}">平台动态</div>
                <div th:classappend="${(#strings.equals(#request.getParameter('type'),'2') ? 'S224_on_point ' : '') + 'S224_message_kind pageChange'}" th:attr="data-page=@{/notification/list(type=2)}">产品消息</div>
                <div th:classappend="${(#strings.equals(#request.getParameter('type'),'3') ? 'S224_on_point ' : '') + 'S224_message_kind pageChange'}" th:attr="data-page=@{/notification/list(type=3)}">财务消息</div>
                <div th:classappend="${(#strings.equals(#request.getParameter('type'),'4') ? 'S224_on_point ' : '') + 'S224_message_kind pageChange'}" th:attr="data-page=@{/notification/list(type=4)}">用量消息</div>

thymeleaf中${param.xx}返回的是数组，这一点和jstl不一样，所以此次使用#request.getParameter('type')
