创建表单控制器时使用Spring MVC和Apache Tiles时出错

Question

我有下一个问题，当我创建一个表单和控制器时，视图无法正确呈现。我认为问题是包装表单对象的属性不起作用。 控制器的代码是（见下文）：

@Controller
public class IntervalController {

@ModelAttribute("interval")
 public Interval getGreetingObject() {
  return new Interval();
 }


@RequestMapping(method = RequestMethod.POST, value="/behaviour")
public String processSubmit(
        @ModelAttribute("interval") Interval interval, Model model) {

    model.addAttribute("interval", new Interval());

    return "behaviour";
}


@ModelAttribute("intervalList")
public Map<String,String> intervalList() {

    Map<String,String> interval = new LinkedHashMap<String,String>();
    interval.put("1", "Day (Calendar option)");
    interval.put("7", "Last 7 days");
    interval.put("14", "Last 14 days");
    interval.put("30", "Last 30 days");
    interval.put("90", "Last 90 days");

    return interval;
}
}

包含表格的视图：

<div class="panel-body">
        <form:form method="POST" modelAttribute="interval">
            <form:select path="intervalName" onchange="controlCalendar()" class="input-large form-control">
                <form:option value="NONE" label="--- Select ---"/>
                <form:options items="${intervalList}"/>
            </form:select>
            <div id="datepicker">
                <form:input id="inputDate" style="display: none;" type="text" path="date"/>
            </div>
            <input type="submit" value="submit">  
        </form:form>
    </div>

错误：
