Password confirmation with spring annotation
问题
以下是翻译好的内容：
能否有人解释一下我遇到的错误。我正在按照教程进行密码确认。
2020-05-29 15:23:33.397 ERROR 10832 --- [nio-8080-exec-4] o.a.c.c.C.[.[.[/].[dispatcherServlet] :

如果我没有弄错的话，我已经做得没问题了。
这是我的注册控制器。
@RequestMapping(value = "/registration", method = RequestMethod.GET)
public String showRegistration(WebRequest request, Model model) {
User user = new User();
model.addAttribute("user", user);
return "registration";
}
@RequestMapping(value = "/registration", method = RequestMethod.POST)
public ModelAndView createNewUser(@Valid User user, BindingResult bindingResult, HttpServletRequest request, Errors errors) {
ModelAndView model = new ModelAndView();
User userExists = userService.findUserByName(user.getName());
if (userExists != null) {
bindingResult
.rejectValue("name", "errors.user",
"已经有一个使用提供的用户名注册的用户");
}
if (bindingResult.hasErrors()) {
model.setViewName("registration");
} else {
userService.saveUser(user);
model.addObject("successMessage", "用户已成功注册");
model.addObject("user", new User());
model.setViewName("registration");
}
return model;
}
这是一个服务。
public User saveUser(User user) {
user.setPassword(bCryptPasswordEncoder.encode(user.getPassword()));
user.setActive(true);
Role userRole = roleRepository.findByRole("CUSTOMER");
user.setRoles(new HashSet<>(Arrays.asList(userRole)));
return userRepository.save(user);
}
这是我的模型。抱歉，因为代码太多而导致显示混乱。

Can someone please explain me the error I am getting. I am doing password confirmation by tutorial.

If I am not mistaken I am did everything correctly.
Here is my Registration controller.
@RequestMapping(value = "/registration", method = RequestMethod.GET)
public String showRegistration(WebRequest request, Model model) {
User user = new User();
model.addAttribute("user", user);
return "registration";
}
@RequestMapping(value = "/registration", method = RequestMethod.POST)
public ModelAndView createNewUser(@Valid User user, BindingResult bindingResult, HttpServletRequest request, Errors errors) {
ModelAndView model = new ModelAndView();
User userExists = userService.findUserByName(user.getName());
if (userExists != null) {
bindingResult
.rejectValue("name", "errors.user",
"There is already a user registered with the name provided");
}
if (bindingResult.hasErrors()) {
model.setViewName("registration");
} else {
userService.saveUser(user);
model.addObject("successMessage", "User has been registered successfully");
model.addObject("user", new User());
model.setViewName("registration");
}
return model;
}
This is a service
public User saveUser(User user) {
user.setPassword(bCryptPasswordEncoder.encode(user.getPassword()));
user.setActive(true);
Role userRole = roleRepository.findByRole("CUSTOMER");
user.setRoles(new HashSet<>(Arrays.asList(userRole)));
return userRepository.save(user);
}
This is my model. Sorry for the view. Complaining about too much code
