通过jdbcTemplate如何返回自定义的对象集合，以及在java中如何遍历这个集合

举个例子，比如现在我需要返回数据库中tb_orders表中的日期年份

public List<Map<String,Object>> getOrdersYear(){return jdbcTemplate.queryForList("select DATE_FORMAT(o.exchangeTime,'%Y') as year from tb_orders o where o.`status`='1' group by DATE_FORMAT(o.exchangeTime,'%Y') order by DATE_FORMAT(o.exchangeTime,'%Y')");}


在java中如何解析List<Map<String ,Object>>呢？
List<Map<String, Object>> years= ordersDAO.getOrdersYear();for(Map<String,Object> m:years){for(String year:m.keySet()){System.out.println(m.get("year").toString());}}r.setAttribute("years",years);


在页面中如何获取years呢？
  <select class="select3" name="selectYear" ><c:forEach items="${years }" var="years"><option>${years.year}</option>    </c:forEach>  </select>
