页面实现根据某个字段降序升序排序

前台页面

1 <form id="pagerForm" method="post" action="${ctx}/user/list" onsubmit="return navTabSearch(this)"> 
2     <input type="hidden" name="orderField" value="${page.orderField}" />
3 </form>
4 
5 <th orderField="strAccount">工号</th>

后台mapper里：

1 <choose>
2       <when test="orderField!=null and orderField!=''">
3         order by ${orderField} ${orderDirection}
4       </when>
5       <otherwise>
6         order by createDateTime desc
7       </otherwise>
8  </choose>
