I need to auto-login after a successful registration. I followed these stackoverflow post and article but I get java.lang.StackOverflowError : null when testing my code via Postman.

Controller class:

@RestController
public class RegistrationController {

    @Autowired
    private UserService userService;

    @Autowired
    private AuthenticationManager authenticationManager;

    @PostMapping("/api/user/registration")
    public ResponseEntity registerNewUserAccount(
            @RequestBody @Valid RegistrationDto userDto, HttpServletRequest request){

        userService.save(userDto);
        authenticateUser(userDto, request);

        return ResponseEntity.ok().build();
    }

    private void authenticateUser(RegistrationDto userDto, HttpServletRequest request){
        String username = userDto.getEmailAddress();
        String password = userDto.getPassword();

        UsernamePasswordAuthenticationToken token =
                new UsernamePasswordAuthenticationToken(username, password);

        request.getSession();
        token.setDetails(new WebAuthenticationDetails(request));
        Authentication authenticatedUser =
                authenticationManager.authenticate(token);
        SecurityContextHolder.getContext().setAuthentication(authenticatedUser);
    }
}

SecurityConfiguration class:

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        super.configure(auth);
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                .anyRequest().permitAll()
                .and()
                .csrf().disable();
    }

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

    @Bean
    public BCryptPasswordEncoder cryptPasswordEncoder(){
        return new BCryptPasswordEncoder();
    }
}

I know about StackOverflowError and I guess AuthenticationManagerBuilder or authenticationManagerBean should cause the problem.

Here's a piece of the lengthy error message:

Your guess was right :) You should configure AuthenticationManager correctly. The links you refer don't explicitly show that.

There are many ways how to configure it: Provide an implementation of AuthenticationManager explicitly, or configure a builder that will create an AuthenticationManager, or configure AuthenticationManager via XML, etc. Below are 2 of many possible ways to configure it.


1. Provide your own AuthenticationManager

For some real authentication you can implement an AuthenticationManager that is based on LDAP or JDBC. To demonstrate the idea, here is a dummy implementation which is sufficient to make your code running.

public class DummyAuthenticationManager implements AuthenticationManager {

    @Override
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {
        // Dummy implementation. We don't check anything here.
        return authentication;
    }

}

In your SecurityConfiguration create an instance of it, as follows:

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return new DummyAuthenticationManager();
    }

    ...

}

With these changes your code will be running and you can continue to extend it step by step.


2. Use AuthenticationManagerBuilder

Instead of implementing an AuthenticationManager you can configure AuthenticationManagerBuilder that will build for you an AuthenticationManager that you need.

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
            .withUser("user1").password("password1").roles("USER").and()
            .withUser("user2").password("password2").roles("USER").and()
            .withUser("admin").password("password3").roles("USER", "ADMIN");
    }

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManager();
    }

    ...
}

With these changes your code will be running and you can continue to extend it step by step. For instance, for something realistic instead of inMemoryAuthentication() you can use ldapAuthentication() or jdbcAuthentication() or some other configurer.
