Org.springframework.dao.invaliddataaccessresourceusageException: JDBC -Ausnahme ausführende SQL ⇐ Java

[Anonymous]

Ich breche meinen Kopf, um herauszufinden, was das Problem ist. Br /> Außerdem sehr neu in der Codierung, wenn ich nicht genügend Informationen präsentiere, sagen Sie es mir bitte. < /p>
Hier sind die Dateien meiner Arbeit < /p>

Code: Select all

@Controller
public class UserController {

private UserRepository repository;

public UserController (UserRepository repository) {
this.repository = repository;
}

@GetMapping("/memberRegistration")
public String memberRegistration(@ModelAttribute User user, Model model) {
model.addAttribute("userInputs", repository.findAll());

return "/memberRegistration";
}

@PostMapping("/confirmingRegistration")
public String confirmingRegistration(@Validated @ModelAttribute User user, BindingResult result, Model model) {
model.addAttribute("userInput", repository.findAll());

if (result.hasErrors()) {
return "memberRegistration";
}
repository.save(user);
return "/profile";
}
}

< /code>
@Data
@Entity
@Table(name = "Users")
public class User {
@Id
@GeneratedValue (strategy = GenerationType.IDENTITY)
private Long id;

@NotBlank
@Size(max = 60)

@NotBlank
@Size(max = 60)

}

Ich habe ein paar Tage gegoogelt, um dieses Problem zu lösen, aber ich kann scheinbar nicht weiterentwickeln ...
Vielleicht fehlt mir ein paar Schritte?
Hier ist die Stacktrace < /p>
