我的隱藏表單沒有向我的控制器發送正確的資料，我遇到了這個問題。接下來，我的表格更新了錯誤的資料。我將首先簡要說明代碼的作業原理。然后我會展示相關的代碼。
所以在我的程式中，我用產品 id 填充了一個籃子。之后，您可以選擇一個客戶。然后你進入一個確認螢屏。“你想要這些客戶的產品嗎？現在，下面是一個隱藏的表格，其中還將產品 ID 和 clientId 放在隱藏的輸入欄位中。如果你按下確認，它會確認這個表格，將其發送回控制器，然后控制器進度資料。
現在的問題是我的更新表中的資料是：
Column ClientId = 0
Column ProductId = 0
Column DateTimeStamp = OK, correct stamp
我將提供控制器和下面的 html 頁面。如果有人需要更多資訊，我可以提供。但是我的存盤庫或服務沒有任何問題，這作業得很好。我認為問題出在我的 getRequest 或表單中的某個地方，然后才被確認。
控制器（我忽略了進口）
@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";
}
}
這是我在控制器中參考的相關 html 頁面。您可以假設每個 Service 和 Repository 都運行良好并完成其作業。
<!DOCTYPE html>

這是確認頁面。這是錯誤的。插入到表單隱藏輸入框中的資料不會被提交：

You can see the entire project where I am now on Github, if that is easier.I just pushed everything again: https://github.com/Muschke/eindoefeningmovies
Please I would be so gratefull for some ideas how to make sure I get the right data in my controller. I think the issues lies in my controller @GetMapping("/bevestigen/{id}/form")
Thanks for your feedback!
FYI - the stacktrace of the error when I insert the right fields -as requested. Just says that It cannot bind.

uj5u.com熱心網友回復：
改變：
ModelAndView("bevestigen/{id}").addObject(new Reservatie(0, 0, LocalDateTime.now()));
到：
return new ModelAndView.addObject("reservatie", new Reservatie(0, 0, LocalDateTime.now()));
下面是代碼：
@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(id, mandje.getIds().iterator().next(), LocalDateTime.now()));
return modelAndView;
}
uj5u.com熱心網友回復：
我編輯了映射方法。在較早的 Mapping 方法中將保留添加為物件可確保正確插入表單。但是現在我在驗證中遇到錯誤。
更新方法 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";
}
錯誤

但我沒有插入任何空白，.. 我插入了一個長 ID。
uj5u.com熱心網友回復：
是的！
好的，所以，在我將它們發送到 tymeleafpage 之前，已經啟動了這些值。
@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(id, mandje.getIds().iterator().next(), LocalDateTime.now()));
return modelAndView;
}
所以我想這結束了我的問題。:D 感謝您的幫助 Famaeez！
