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）：

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：
