Question

我在我的控制器中有这个方法来获取所有创建的楼层，以便我可以用它来创建房间记录。

＆＃13;

	@RequestMapping(method = RequestMethod.POST, produces = "text/html")
    public String create(@Valid Room room, BindingResult bindingResult, Model uiModel, HttpServletRequest httpServletRequest) {
        if (bindingResult.hasErrors()) {
            populateEditForm(uiModel, room);
            return "rooms/create";
        }
        uiModel.asMap().clear();
        roomService.saveRoom(room);
        return "redirect:/rooms/" + encodeUrlPathSegment(room.getId().toString(), httpServletRequest);
    }

	@RequestMapping(params = "form", produces = "text/html")
    public String createForm(Model uiModel) {
        populateEditForm(uiModel, new Room());
        return "rooms/create";
    }





	void populateEditForm(Model uiModel, Room room) {
        uiModel.addAttribute("room", room);
        uiModel.addAttribute("floors", Floor.findAllFloors());
    }

＆＃13;

然后，我最初在我的视图页面中显示此代码，以在下拉列表中显示楼层：

＆＃13;

<field:select field="floor"
id="c_ph_com_smesoft_hms_domain_Room_floor" itemValue="id"
items="${floors}" path="/floors" z="BO2RLJSaIYxNwRbKJMRipi883S8=" />

＆＃13;

上面的代码非常好用。如何将此代码翻译成以下格式：

＆＃13;

<select>
<c:forEach>
<option></option>
</c:forEach>
</select>

＆＃13;

Answer 1

它认为它应该是这样的。

<select name="floor">
<c:forEach items="floors" var="floor">
<option value="${floors.id}">${floors}</option>
</c:forEach>
</select>

从数据库填充下拉菜单
