How to get logged in after signup in spring security?

Question

In spring security, log in is done through the specified login page in the securityconfig class. Following is the code..

@Override
protected void configure(HttpSecurity http) throws Exception {

    http.formLogin().loginPage("/login").defaultSuccessUrl("/")
}

But I also want my users to get logged in right after they sign up. I tried something like:

@Override
protected void configure(HttpSecurity http) throws Exception {

    http.formLogin().loginPage("/login", "/signup").defaultSuccessUrl("/")
}

But this does not work. How do I do this in spring security?

Auto login is not related with Spring Security Configuration file.... it's depend on your developing programming logic ...

after complete successful signup process you can call a login method, it will be give valid login session of that user. you can try this code ...

@Override
public void autoLogin(String username, String password) {
    UserDetails userDetails = userDetailsService.loadUserByUsername(username);
    UsernamePasswordAuthenticationToken usernamePasswordAuthenticationToken = new UsernamePasswordAuthenticationToken(userDetails, password, userDetails.getAuthorities());

    authenticationManager.authenticate(usernamePasswordAuthenticationToken);

    if (usernamePasswordAuthenticationToken.isAuthenticated()) {
        SecurityContextHolder.getContext().setAuthentication(usernamePasswordAuthenticationToken);
        logger.debug(String.format("Auto login %s successfully!", username));
    }
}
