Question

嗨我正在尝试在jsp中打印arraylist的内容这是控制器代码

    @RequestMapping(value = "/deleteFilter", method = RequestMethod.GET)
    public String deleteFilter(FilterValues filterData,ModelMap modalMap) {

    logger.info("delete a filter");
    ArrayList<String> filtername= mongoService.getTargetFiltersName();
    modalMap.addAttribute("filterslist",  filtername);

    return "delete";
}

这里是jsp的一部分，我必须打印它

 <div class="col-xs-4">
                        <label for="pwd">Filter Name:</label>
                         <select type="Filter Name" class="form-control" id="pwd"     placeholder="Enter Filter Name">
                         <c:forEach items="${filterslist}" var="filtername">
                                 <option value="${filtername.value}">${filtername.value}</option>
                        </c:forEach>
                        </select>                   
                        </div>

它给我的错误

提前致谢

我认为您应该使用以下代码，因为您正在ArrayList String上进行迭代

<div class="col-xs-4">
<label for="pwd">Filter Name:</label>
 <select type="Filter Name" class="form-control" id="pwd" placeholder="Enter Filter Name">
 <c:forEach items="${filterslist}" var="filtername">
         <option value="${filtername}">${filtername}</option>
</c:forEach>
</select>                  
</div>

从控制器传递给jsp时打印一个arraylist
