How to manually set an authenticated user in Spring Security SpringMVC

Question

After a new user submits a  New account  form  I want to manually log that user in so they don t have to login on the subsequent page   The normal form login page going through the spring security interceptor works just fine   In the new-account-form controller I am creating a UsernamePasswordAuthenticationToken and setting it in the SecurityContext manually   SecurityContextHolder getContext   setAuthentication authentication     On that same page I later check that the user is logged in with   SecurityContextHolder getContext   getAuthentication   getAuthorities      This returns the authorities I set earlier in the authentication  All is well   But when this same code is called on the very next page I load  the authentication token is just UserAnonymous   I m not clear why it did not keep the authentication I set on the previous request  Any thoughts    Could it have to do with session ID s not being set up correctly  Is there something that is possibly overwriting my authentication somehow  Perhaps I just need another step to save the authentication  Or is there something I need to do to declare the authentication across the whole session rather than a single request somehow    Just looking for some thoughts that might help me see what s happening here

I couldn t find any other full solutions so I thought I would post mine   This may be a bit of a hack  but it resolved the issue to the above problem   public void login HttpServletRequest request  String userName  String password         UsernamePasswordAuthenticationToken authRequest   new UsernamePasswordAuthenticationToken userName  password           Authenticate the user     Authentication authentication   authenticationManager authenticate authRequest       SecurityContext securityContext   SecurityContextHolder getContext        securityContext setAuthentication authentication           Create a new session and add the security context      HttpSession session   request getSession true       session setAttribute  SPRING SECURITY CONTEXT   securityContext

Ultimately figured out the root of the problem   When I create the security context manually no session object is created  Only when the request finishes processing does the Spring Security mechanism realize that the session object is null  when it tries to store the security context to the session after the request has been processed    At the end of the request Spring Security creates a new session object and session ID  However this new session ID never makes it to the browser because it occurs at the end of the request  after the response to the browser has been made  This causes the new session ID  and hence the Security context containing my manually logged on user  to be lost when the next request contains the previous session ID

The new filtering feature in Servlet 2 4 basically alleviates the restriction that filters can only operate in the request flow before and after the actual request processing by the application server  Instead  Servlet 2 4 filters can now interact with the request dispatcher at every dispatch point  This means that when a Web resource forwards a request to another resource  for instance  a servlet forwarding the request to a JSP page in the same application   a filter can be operating before the request is handled by the targeted resource  It also means that should a Web resource include the output or function from other Web resources  for instance  a JSP page including the output from multiple other JSP pages   Servlet 2 4 filters can work before and after each of the included resources      To turn on that feature you need   web xml   lt filter gt          lt filter-name gt springSecurityFilterChain lt  filter-name gt          lt filter-class gt org springframework web filter DelegatingFilterProxy lt  filter-class gt    lt  filter gt     lt filter-mapping gt          lt filter-name gt springSecurityFilterChain lt  filter-name gt          lt url-pattern gt   lt strike gt   lt  strike gt  lt  url-pattern gt       lt dispatcher gt REQUEST lt  dispatcher gt       lt dispatcher gt FORWARD lt  dispatcher gt   lt  filter-mapping gt    RegistrationController  return  forward  login j username     registrationModel getUserEmail               amp j password     registrationModel getPassword

I was trying to test an extjs application and after sucessfully setting a testingAuthenticationToken this suddenly stopped working with no obvious cause   I couldn t get the above answers to work so my solution was to skip out this bit of spring in the test environment  I introduced a seam around spring like this    public class SpringUserAccessor implements UserAccessor        Override     public User getUser                 SecurityContext context   SecurityContextHolder getContext            Authentication authentication   context getAuthentication            return  User  authentication getPrincipal              User is a custom type here   I m then wrapping it in a class which just has an option for the test code to switch spring out   public class CurrentUserAccessor       private static UserAccessor  accessor       public CurrentUserAccessor                  accessor   new SpringUserAccessor               public User getUser                 return  accessor getUser               public static void UseTestingAccessor User user                 accessor   new TestUserAccessor user             The test version just looks like this   public class TestUserAccessor implements UserAccessor       private static User  user       public TestUserAccessor User user                 user   user              Override     public User getUser                 return  user            In the calling code I m still using a proper user loaded from the database       User user    User   userService loadUserByUsername username       CurrentUserAccessor UseTestingAccessor user     Obviously this wont be suitable if you actually need to use the security but I m running with a no-security setup for the testing deployment   I thought someone else might run into a similar situation   This is a pattern I ve used for mocking out static dependencies before   The other alternative is you can maintain the staticness of the wrapper class but I prefer this one as the dependencies of the code are more explicit since you have to pass CurrentUserAccessor into classes where it is required

Turn on debug logging to get a better picture of what is going on   You can tell if the session cookies are being set by using a browser-side debugger to look at the headers returned in HTTP responses    There are other ways too    One possibility is that SpringSecurity is setting secure session cookies  and your next page requested has an  http  URL instead of an  https  URL    The browser won t send a secure cookie for an  http  URL

I had the same problem as you a while back  I can t remember the details but the following code got things working for me  This code is used within a Spring Webflow flow  hence the RequestContext and ExternalContext classes  But the part that is most relevant to you is the doAutoLogin method    public String registerUser UserRegistrationFormBean userRegistrationFormBean                             RequestContext requestContext                             ExternalContext externalContext         try           Locale userLocale   requestContext getExternalContext   getLocale            this userService createNewUser userRegistrationFormBean  userLocale  Constants SYSTEM USER ID           String emailAddress   userRegistrationFormBean getChooseEmailAddressFormBean   getEmailAddress            String password   userRegistrationFormBean getChoosePasswordFormBean   getPassword            doAutoLogin emailAddress  password   HttpServletRequest  externalContext getNativeRequest             return  success          catch  EmailAddressNotUniqueException e            MessageResolver messageResolvable                    new MessageBuilder   error                                          source UserRegistrationFormBean PROPERTYNAME EMAIL ADDRESS                                         code  userRegistration emailAddress not unique                                          build            requestContext getMessageContext   addMessage messageResolvable           return  error              private void doAutoLogin String username  String password  HttpServletRequest request         try              Must be called from request filtered by Spring Security  otherwise SecurityContextHolder is not updated         UsernamePasswordAuthenticationToken token   new UsernamePasswordAuthenticationToken username  password           token setDetails new WebAuthenticationDetails request            Authentication authentication   this authenticationProvider authenticate token           logger debug  Logging in with        authentication getPrincipal             SecurityContextHolder getContext   setAuthentication authentication         catch  Exception e            SecurityContextHolder getContext   setAuthentication null           logger error  Failure in autoLogin   e
