Spring MVC に問題があります。

@RequestMapping(value = "/novo", method = RequestMethod.GET)
public ModelAndView novoTimeSheet() {
    return new ModelAndView("timesheetcrud/novo", "timesheet", new TimeSheet());
}

私TimeSheetのクラスは：

@NotNull(message = "timesheet.cadastro.horainicio.obrigatorio")
@Temporal(TemporalType.TIME)
@Column(name = "INICIO", nullable = false)
private Date horaInicio;

@NotNull(message = "timesheet.cadastro.horafim.obrigatorio")
@Temporal(TemporalType.TIME)
@Column(name = "FIM", nullable = false)
private Date horaFim;

私のaddTimeSheet：

@RequestMapping(value = "/addtimesheet", method = RequestMethod.POST)
public String addTimeSheet(@ModelAttribute("timesheet")TimeSheet timeSheet,
                         ModelMap model) {

ブラウザで、日付が等しくないものを入力すると、次のエラーが発生します。

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.validation.BindException: org.springframework.validation.BeanPropertyBindingResult: 2 errors

どうすればいいですか？期待していますDateが、フィールドに入れStringました。コントローラーの前に検証したいと思います。

次のようなバインディングをコントローラーに追加する必要があります。

@InitBinder
protected void initBinder(WebDataBinder binder) {
    SimpleDateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy");
    binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, false));
}
