Answer 1

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) {         String username = user.getUsername();         String password = user.getPassword();         UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(username, password);          // 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
