我整天都在尝试将 jQuery datepicker 函数与 java.util.Date 类型的基础 java spring 表单日期字段的两个字段绑定，但出现错误。我正在发布所有文件和错误消息。

form.jspx（jquery 是从瓦片默认模板加载的）：

表单数据.java：

package domain;

import org.springframework.format.annotation.DateTimeFormat;

import java.util.Date;


public class FormData {

    private String stateCode;

    private String city;

    @DateTimeFormat(pattern = "yy-mm-dd")
    private Date arrivalDate;

    @DateTimeFormat(pattern = "yy-mm-dd")
    private Date departureDate;

    private Integer numberOfAdults;

    //getters and setters
    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }

    public Date getArrivalDate() {
        return arrivalDate;
    }

    public void setArrivalDate(Date arrivalDate) {
        this.arrivalDate = arrivalDate;
    }

    public Date getDepartureDate() {
        return departureDate;
    }

    public void setDepartureDate(Date departureDate) {
        this.departureDate = departureDate;
    }

    public Integer getNumberOfAdults() {
        return numberOfAdults;
    }

    public void setNumberOfAdults(Integer numberOfAdults) {
        this.numberOfAdults = numberOfAdults;
    }

    //other methods
    public String toString()
    {
        if (city.equals("New York"))
            stateCode = "NY";
        else if(city.equals("Los Angeles"))
            stateCode = "CA";
        else if(city.equals("Chicago"))
            stateCode = "IL";
        else if(city.equals("Houston"))
            stateCode = "TX";
        else if(city.equals("Phoenix"))
            stateCode = "AZ";



        return "http://api.ean.com/ean" + "-" + "services/rs/hotel/v3/list?cid=55505&apiKey=97zvrux6eahgv64r3aarb7n2&locale=en_US&currencyCode=USD"
                + "&city=" + city

                + "&numberOfResults=1";

}

搜索控制器.java：

package web.search.controller;

import domain.FormData;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import web.blogapp.controller.EntryController;


@RequestMapping("/search")
@Controller
public class SearchController {

    final Logger logger = LoggerFactory.getLogger(EntryController.class);

    @RequestMapping(method = RequestMethod.GET)
    public String loadFormPage(Model uiModel) {
        logger.info("Listing blog entries");

        uiModel.addAttribute("formdata", new FormData());


        return "search/form";
    }

    @RequestMapping(method = RequestMethod.POST)
    public String submitForm(@ModelAttribute FormData formdata, Model uiModel)
    {
        uiModel.addAttribute("message", "Successfully saved data: " + formdata.toString());
        return "search/form";
    }
}

按提交后我得到的错误如下：
