Answer 1

I'm not sure if you are asking for this, but in your Spring Security configuration you can add a "remember-me" tag. This will manage a cookie in your client, so next time (if the cookie hasn't expired) you'll be logged automatically.

<http>
    ...
    <remember-me />
</http>

Answer 2

This can be done with spring security in the following manner(semi-psuedocode):

    import org.springframework.security.web.savedrequest.RequestCache;
import org.springframework.security.web.savedrequest.SavedRequest;

@Controller
public class SignupController
{

    @Autowired
    RequestCache requestCache;

    @Autowired
    protected AuthenticationManager authenticationManager;

    @RequestMapping(value = "/account/signup/", method = RequestMethod.POST)
    public String createNewUser(@ModelAttribute("user") User user, BindingResult result,  HttpServletRequest request, HttpServletResponse response)
    {
        //After successfully Creating user
            authenticateUserAndSetSession(user, request);

        return "redirect:/home/";
    }

    private void authenticateUserAndSetSession(User user,
        HttpServletRequest request)
{
    UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(
            user.getUsername(), user.getPassword());

    // generate session if one doesn't exist
    request.getSession();

    token.setDetails(new WebAuthenticationDetails(request));
    Authentication authenticatedUser = authenticationManager.authenticate(token);

    SecurityContextHolder.getContext().setAuthentication(authenticatedUser);
}

}

Update: to only contain how to create the session after the registration
