I try to create simple user login and registration page. But I cannot create user using services method.
I have a service for creating new user.
@Service
public class LocalUserDetailsService implements UserService {
//...
@Transactional
@Override
public User registerNewUserAccount(UserDto userDto) throws EmailExistsException {
System.out.println("registerNewUserAccount called");
if (emailExist(userDto.getEmail())) {
throw new EmailExistsException(
"There is an account with that email adress: "
+ userDto.getEmail());
}
return createUser(userDto);
}
private User createUser(UserDto userDto) {
User user = new User();
user.setEmail(userDto.getEmail());
user.setPassword(passwordEncoder.encode(userDto.getPassword()));
user.setEnabled(userDto.isEnabled());
Set<Role> roles = new LinkedHashSet<>();
userDto.getRoles().forEach((roleDto) -> {
roles.add(roleDao.getOrInsert(roleDto.getName()));
});
user.setRoles(roles);
return userDao.insert(user);
}
}
I call registerNewUserAccount(UserDto userDto)
method at 2 places.
1) At startup, I call this method for creating initial users.
@Component
public class DatabaseFillerOnStartup implements ApplicationListener {
@Autowired
private UserService userService;
@Override
public void onApplicationEvent(ContextRefreshedEvent event) {
System.out.println("DatabaseFillerOnStartup ###################");
createInitialUsers();
}
private void createInitialUsers() {
try {
UserDto user = new UserDto();
user.setEmail("[email protected]");
user.setPassword("123456");
user.setEnabled(true);
List<RoleDto> roles = new ArrayList<>();
roles.add(new RoleDto(Roles.ADMIN));
roles.add(new RoleDto(Roles.USER));
user.setRoles(roles);
userService.registerNewUserAccount(user);
} catch (EmailExistsException ex) {
Logger.getLogger(DatabaseFillerOnStartup.class.getName())
.log(Level.SEVERE, null, ex);
}
}
Then all works normally. But when I call this method from controller for creating new user using registration form, registerNewUserAccount(UserDto userDto)
method does not work. I call it from controller like following:
@Controller
public class UserController {
@Autowired
private UserService userService;
@RequestMapping(value = "/user/registration", method = RequestMethod.POST)
public ModelAndView registerUserAccount(
@ModelAttribute("userDto") @Valid UserDto userDto,
BindingResult result, WebRequest request, Errors errors) {
User registered = new User();
if (!result.hasErrors()) {
registered = createUserAccount(userDto, result);
}
if (registered == null) {
result.rejectValue("email", "message.regError");
}
if (result.hasErrors()) {
return new ModelAndView("registration", "user", userDto);
} else {
return new ModelAndView("successRegister", "user", userDto);
}
}
private User createUserAccount(UserDto userDto, BindingResult result) {
User registered;
try {
userService.test();//Just for testing if service class Autowired correctly.
registered = userService.registerNewUserAccount(userDto);
} catch (EmailExistsException e) {
return null;
}
return registered;
}
}
I debugged it. The command userService.test();
passed, but at registerNewUserAccount(UserDto userDto)
command thrown the following exception
