Spring Boot, OAuth2 authentication is lost between requests

EDIT:

log from org.springframework.security:

***But if I look in the logs some requests after I can get the valid auth:

it looks like the session id is inconsistent

---

I use spring security builtin oauth2 social login option, I implemented an OAuth2LoginSuccess class with the onAuthenticationSuccess method and inside of it I fetch the user the corresponds to the social id I got from the oauth:

CustomOAuth2User oAuth2User = (CustomOAuth2User) authentication.getPrincipal();
int sociald = oAuth2User.getAttribute("id");
User user = usersUtils.getUserBySocailId(socialId);
enter code here
// add the user details to the Auth
SecurityContextHolder.clearContext();
((OAuth2AuthenticationToken) authentication).setDetails(user);
SecurityContextHolder.getContext().setAuthentication(authentication);

If I debug inside the onAuthenticationSuccess I can see a valid auth with all the user details.

after the login I redirect to the home page and i send a auth get request to the server to check if there is a user logged in.

the problem is that 50% of the times the request is completed successfuly and the user can make authenticated requets.

but the other 50% i get redirected automaticly to Login page and when i check the log is see that Spring boot says that the user is unauthenticated and the auth is lost.

But in the onAuthenticationSuccess i can always see the correct auth.

My ApplicationSecurityConfig looks like this:

    http.csrf().disable().authorizeRequests()
            .antMatchers("/login*", "/signin/**", "/signup/**", "/oauth2/**").permitAll()
            .antMatchers(Constants.ADMIN_PREFIX + "/**").hasRole("ADMIN")
            .antMatchers(Constants.AUTH_PREFIX + "/**").hasAnyRole("ADMIN", "USER")
            .antMatchers(Constants.PUBLIC_PREFIX + "/**").permitAll()
            .anyRequest().permitAll()
            .and()
            .exceptionHandling().authenticationEntryPoint(new UnauthenticatedRequestHandler())
            .and()
            .formLogin()
            .passwordParameter("password")
            .usernameParameter("email")
            .loginPage("/Login")
            .loginProcessingUrl("/loginSecure").permitAll().successHandler(new LoginSuccess()).failureHandler(new FailureSuccess())
            .and()
            .oauth2Login()
            .loginPage("/Login")
            .userInfoEndpoint()
            .userService(oAuth2UserService)
            .and()
            .successHandler(new OAuth2LoginSuccess())
            .and()
            .rememberMe()
            .rememberMeParameter("remember-me")
            .tokenValiditySeconds((int) TimeUnit.DAYS.toSeconds(21))
.userDetailsService(this.applicationUserService)
            .and()
            .logout()
         .clearAuthentication(true).invalidateHttpSession(true).logoutSuccessUrl("/login")
            .addLogoutHandler(new CustomLogOutHandler());

And this is the function i check if the user is logged in:

   @GetMapping(Constants.AUTH_PREFIX + "/checkUserLogged")
public Integer checkUserLogged(Authentication authentication,HttpServletRequest request) {
    try{
        if (authentication != null) {
            User (User) authentication.getDetails();
            if (user == null) {
                return -1;
            }
            return user.getId();
        }
    }
    catch (Exception e){
        logger.warning(e.getLocalizedMessage());
    }
    return -1;
}

but when the problem occur it dosen’t get to run the controller because spring security return unauthrozed error before.

Thank you in advance for your help

Answer

I found the solution, I hope this could help.

The thing that caused the problem for me was that GCP and GAE use multiple instances of the server, and if the user is logged in a certain instance does not mean the other instances are familiar with it too because the Spring HTTPSession is in-memory.

I Switched the Session platform to use the spring-session jdbc using the following configuration in the application.properties :

spring.session.store-type=jdbc

— you can use redis instead of jdbc, as long as the session is stored in a shared place among all instances.

also added the transaction manager to the SecurtityConfig:

@Bean
public PlatformTransactionManager transactionManager(DataSource dataSource) {
    return new DataSourceTransactionManager(dataSource);
}

and added the following configurations :

    http.csrf().disable()
            .sessionManagement()
            .maximumSessions(1)
            .and()
            .sessionCreationPolicy(SessionCreationPolicy.ALWAYS)

In addition like @stringy05 mentioned the authrizenClient Repository needs ti be updated too:

    /**
 * Use the servlet container session store for authorized OAuth2 Clients
 */
@Bean
public OAuth2AuthorizedClientRepository authorizedClientRepository() {
    return new HttpSessionOAuth2AuthorizedClientRepository();
}

and add the .authorizedClientRepository line to the httpconfig:

....
                .oauth2Login()
            .loginPage("/Login")
            .authorizedClientRepository(authorizedClientRepository)
            .authorizationEndpoint().and()
            .userInfoEndpoint()
            .userService(oAuth2UserService)
            .and()
            .successHandler(new OAuth2LoginSuccess())

….

Regarding the GAE, I added the following line to the app.yaml file:

  network:
    session_affinity: true
