使用静态类实现JSP自定义标签

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>${vote:pictype(vote.pictype)}</td>
            <td align="center">
                  <a href="vote_update.jsp(SUN企业级应用的首选)?id=${vote.id}">修改投票</a>
                <a href="<%=context %>/deleteVote.do?id=${vote.id}">删除投票</a>
                <a href="voteitem_updatein.jsp(SUN企业级应用的首选)?id=${vote.id}">修改选项</a>
            </td>
        </tr>
        </c:forEach>
