как сделать автоматическую авторизацию после регистрации в spring sequrity

Всем привет. Не могу сделать автоматическую авторизацию после регистрации. После регистрации пользователя кидает на страницу логина и не регистрирует в системе. Заранее спасибо за ответы!

@Autowired
private AuthenticationManager authenticationManager;
@PostMapping("/registration")
public String registration(@ModelAttribute("userForm") User userForm, Model model, HttpServletRequest request) {
    if (userService.findByUsername(userForm.getUsername()) != null) {
        model.addAttribute("userPresent", true);
        return "registration";
    }
    userService.save(userForm);
    authWithAuthManager(request, userForm.getUsername(), userForm.getPassword());
    return "redirect:/main";
}
public void authWithAuthManager(HttpServletRequest request, String username, String password) {
    UsernamePasswordAuthenticationToken authToken = new UsernamePasswordAuthenticationToken(username, password);
    authToken.setDetails(new WebAuthenticationDetails(request));
    Authentication authentication = authenticationManager.authenticate(authToken);
    SecurityContextHolder.getContext().setAuthentication(authentication);
}
