可以通过以下方式（半伪代码）通过spring安全性完成此操作：
import org.springframework.security.web.savedrequest.RequestCache;import org.springframework.security.web.savedrequest.SavedRequest;@Controllerpublic 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); }}更新：仅包含注册后如何创建会话
