jsp接收到controller传来的list集合 怎么把list集合里的值添加到动态生成的下拉列表，求救。。。。急急急

controller代码如下：

prizeLevelVos：是前台动态生成的下拉列表需要的
compPrizeVos:是前台需要的数据
 

@RequestMapping(value = "", method = RequestMethod.GET)

public String compIndex(Model model,Long id){   List<PrizeLevelVo> prizeLevelVos=compPrizeService.findAllLevel();    List<CompPrizeVo> compPrizeVos=compPrizeService.findAll();    model.addAttribute("compPrizeVos",compPrizeVos);    model.addAttribute("prizeLevelVos",prizeLevelVos);       return "admin/competion/compArrange/comp-plan";}

这是前台代码，动态生成的一组下拉列表 生成效果如下： 我想把后台传来的那个数据填充到这几个控件里。

<div>       <hr/>    <form class="form-horizontal form-bordered form-label-stripped form-validation"               action="${ctx}/admin/sys/notify-message/edit" method="post" modelAttribute="compPrizeVo"               data-editrulesurl="${ctx}/admin/util/validate?clazz=${clazz}">        <input type="hidden"  name="id"  value="${compVo.id}" />        <div class="form-body">            <c:forEach var="prizeLevelVo" items="${prizeLevelVos}" varStatus="i">                <div class="row">                    <input type="hidden" name="id" value="${prizeLevelVo.id}">                    <div class="col-md-6">                        <div class="form-group">                            <label class="control-label">是否设置${prizeLevelVo.level}</label>                            <div class="controls">                                <select style="width: 100%;height:30px;border-color: #e5eaeb" name="prizeLevel_id">                                    <option value=""  selected="selected">不设置${prizeLevelVo.level}</option>                                    <option value="${prizeLevelVo.id}">设置${prizeLevelVo.level}</option>                                </select>                            </div>                        </div>                    </div>                    <div class="col-md-6">                        <div class="form-group">                            <label class="control-label">${prizeLevelVo.level}人数</label>                            <div class="controls">                                <input type="number" name="number" class="form-control" />                                <span class="help-block">请填写具体的数字或百分比 如：10 或 10%</span>                            </div>                        </div>                    </div>                </div>            </c:forEach>        </div>        <div class="form-actions">            <button class="btn default"  style="float: right" type="button" >返回</button>            <button class="btn green"  style="float: right" type="submit" >保存</button>        </div>    </form></div>
