freemarker遍历map,该怎么解决

        <#list quotemap?keys as hotel>            $("tbody").append("<tr hid='${hotel.id?c}'><td class='hname' ><span class='h_name'><@etdsmacro.i18n _obj=hotel _express="name" /></span></tr>");                      <#list quotemap[hotel]?keys as room>  //这里遍历有问题                      $("tbody").append("<tr><td>${room.id }</td></tr>");                      </#list>        </#list>
