注意,实现的方法必须是静态的

<%...@ taglib uri="http://hxex.cn/vote" PRefix="vote" %>
<c:forEach var="vote" items="${votes}">
     <tr>
       <td>${vote.name}</td>
       <td>${vote.title}</td>
       <td>${vote:votetype(vote.votetype)}</td>
       <td>${vote:pictype(vote.pictype)}</td>
       <td align="center">
          <a href="vote_update.jsp?id=${vote.id}">修改投票</a>
         <a href="<%=context %>/deleteVote.do?id=${vote.id}">删除投票</a>
         <a href="voteitem_updatein.jsp?id=${vote.id}">修改选项</a>
