我想要在spring成功注册后自动登录：我有一个受保护的页面，需要登录才能访问它们，我要在注册后跳过登录页面并进行自动登录，以便用户可以看到受保护的页面有我吗？我正在使用spring 3.0，spring security 3.0.2，该怎么做？

回答：

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;
@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);
    }
}
