У меня есть проблема со ссылкой для обновления моей транзакции.На одном jsp у меня есть список с транзакциями, и после нажатия кнопки «Обновить», которая является ссылкой, я хотел передать файл TransactionsId, обновить его, сохранить и вернуться к списку. Я использовал скрытый параметр c: и он не работает. У меня нетИдея, почему он не передает формы id и автозаполнения. Кажется, что значения передаются в сеансе, когда я нажал кнопку тестирования транзакции:
http://localhost:8080/transaction/addTransaction?transactionId=64&userId=1
Вот контроллер транзакции:
@Controller
@RequestMapping("/transaction")
public class TransactionController {
@Autowired
TransactionService transactionService;
@Autowired
CategoryService categoryService;
@Autowired
UserService userService;
@GetMapping("/addTransaction")
public String transactionsList(Model theModel){
Transaction transaction = new Transaction();
theModel.addAttribute("user",userService.getAllUsers());
theModel.addAttribute("category", categoryService.getAllCategories());
theModel.addAttribute("newTransaction", transaction);
return "addTransaction";
}
@PostMapping("/saveTransaction")
public String saveTransaction(@ModelAttribute("newTransaction") Transaction
newTransaction,
BindingResult theBindingResult,
HttpServletRequest request) throws
ParseException {
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd");
String date = request.getParameter("transactionDate");
LocalDate localDate = LocalDate.parse(date, formatter);
Date formatedDate =
Date.from(localDate.atStartOfDay().toInstant(ZoneOffset.ofHours(-3)));
newTransaction.setTransactionDate(formatedDate);
transactionService.saveTransaction(newTransaction);
return "redirect:/user/userPage";
}
@GetMapping("/deleteTransaction")
public String deleteUser(@RequestParam("transactionId") int idFromTransactionToDelete,
@RequestParam("userId") int loggedUserId,
RedirectAttributes redirectAttributes){
transactionService.deleteTransactionById(idFromTransactionToDelete);
User loggedUser = userService.getUserById(loggedUserId);
redirectAttributes.addFlashAttribute("loggedUser", loggedUser);
return "redirect:/user/userPage";
}
@GetMapping("/updateTransaction")
public String updateUser(@RequestParam("transactionId") int
idFromTransactionToUpdate,
@RequestParam("userId") int loggedUserId,
RedirectAttributes redirectAttributes,
Model theModel){
Transaction transactionToUpdate = transactionService.getSingleTransactionById(idFromTransactionToUpdate);
transactionToUpdate.setUser(userService.getUserById(loggedUserId));
theModel.addAttribute("newTransaction",transactionToUpdate);
theModel.addAttribute("category", categoryService.getAllCategories());
User loggedUser = userService.getUserById(loggedUserId);
redirectAttributes.addFlashAttribute("loggedUser", loggedUser);
redirectAttributes.addFlashAttribute("newTransaction",
transactionToUpdate);
return "addTransaction";
}
}

И добавить транзакцию в формуляр:
