问题：
表单发送错误的数据
吴腾
Column ClientId = 0
Column ProductId = 0
Column DateTimeStamp = OK, correct stamp
控制器（我忽略了导入）
@Controller
@RequestMapping("klanten")
class KlantController {
private final KlantService klantService;
private final FilmService filmService;
private final ReservatieService reservatieService;
private final Mandje mandje;
KlantController(KlantService klantService, FilmService filmService, ReservatieService reservatieService, Mandje mandje) {
this.klantService = klantService;
this.filmService = filmService;
this.reservatieService = reservatieService;
this.mandje = mandje;
}
//form in de pagina steken
@GetMapping("/form")
public ModelAndView findByStartlettersForm() {
return new ModelAndView("klanten").addObject(new vindNaamAdhvLettersForm(null));
}
//form verwerken ! geen post gebruiken
@GetMapping
public ModelAndView findByStartletters(vindNaamAdhvLettersForm form, Errors errors) {
var modelAndview = new ModelAndView("klanten");
if(errors.hasErrors()){
return modelAndview;
}
return modelAndview.addObject("klantenMetStartletters", klantService.findByBevatLetters(form.getLetters()));
}
@GetMapping("/bevestigen/{id}")
public ModelAndView findByIdKlant(@PathVariable long id) {
var modelAndView = new ModelAndView("bevestigen");
klantService.findById(id)
.ifPresent(klant -> {
modelAndView.addObject("klant", klant);
});
modelAndView.addObject("filmsInMandje", mandje.telAantalFilms());
modelAndView.addObject("filmIds", mandje.getIds());
return modelAndView;
}
@GetMapping("/bevestigen/{id}/form")
public ModelAndView toevoegenReservatie(){
return new ModelAndView("bevestigen/{id}").addObject(new Reservatie(0, 0, LocalDateTime.now()));
}
@PostMapping("/bevestigen/verwerken")
public String toevoegenEnUpdaten(@Valid Reservatie reservatie, Errors errors) {
/* if(errors.hasErrors()){
return "/klanten/bevestigen/{id}";
}*/
reservatieService.updateAndCreate(reservatie);
return "redirect:/rapport";
}
}
下面是我在控制器中引用的相关html页面。您可以假设每一个服务和存储库都正常工作，并完成了它的工作。

这是确认页面。这里有点不对劲。插入到表单的隐藏输入框中的数据不会被提交：

我编辑了映射方法。在前面的映射方法中将保留作为对象添加，确保表单插入正确。但是现在我在验证中得到了一个错误。
更新的方法KlantController：
@GetMapping("/bevestigen/{id}")
public ModelAndView findByIdKlant(@PathVariable long id) {
var modelAndView = new ModelAndView("bevestigen");
klantService.findById(id)
.ifPresent(klant -> {
modelAndView.addObject("klant", klant);
});
modelAndView.addObject("filmsInMandje", mandje.telAantalFilms());
modelAndView.addObject("filmIds", mandje.getIds());
modelAndView.addObject("reservatie", new Reservatie(0, 0, LocalDateTime.now()));
return modelAndView;
}
@PostMapping("/bevestigen/{id}")
public String toevoegenEnUpdaten(@Valid Reservatie reservatie, Errors errors) {
/* if(errors.hasErrors()){
return "/klanten/bevestigen/{id}";
}*/
reservatieService.updateAndCreate(reservatie);
return "redirect:/rapport";
}
