Unable to authenticate with UsernameAndPasswordToken and set Cookie with Spring Security - authentication

Question

I am building Spring Boot/ReactJS app and i have following issue in authenticating the user and generating JSSESSIONID.
My SecurityConfig class looks like this:
#Configuration
#EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
private UserService userService;
#Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userService).passwordEncoder(bCryptPasswordEncoder());
}
#Override
#Bean(BeanIds.AUTHENTICATION_MANAGER)
protected AuthenticationManager authenticationManager() throws Exception {
return super.authenticationManager();
}
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/login").permitAll()
.anyRequest().authenticated()
.and()
.logout().deleteCookies("JSESSIONID")
.and()
.rememberMe().key("uniqueAndSecret").tokenValiditySeconds(86400)
.and()
.csrf().disable();
}
#Bean
BCryptPasswordEncoder bCryptPasswordEncoder() { return new BCryptPasswordEncoder();}
}
And my LoginController:
#RestController
#RequestMapping(path="/",produces = "application/json")
#CrossOrigin(origins="*")
public class LoginController {
private final AuthenticationManager authenticationManager;
public LoginController(AuthenticationManager authenticationManager) {
this.authenticationManager = authenticationManager;
}
#PostMapping("/login")
#ResponseStatus(HttpStatus.OK)
public void login(HttpServletRequest req, #RequestBody LoginRequest loginRequest) {
UsernamePasswordAuthenticationToken authReq
= new UsernamePasswordAuthenticationToken(loginRequest.getUsername(), loginRequest.getPassword());
Authentication auth = authenticationManager.authenticate(authReq);
SecurityContext sc = SecurityContextHolder.getContext();
sc.setAuthentication(auth);
HttpSession session = req.getSession(true);
session.setAttribute(SPRING_SECURITY_CONTEXT_KEY, sc);
}
}
And when i call request, i have a BadCredentials exception thrown when calling authenticationManager.authenticate(authReq)
because the authReq's content log is
org.springframework.security.authentication.UsernamePasswordAuthenticationToken#6582813: Principal: pavel; Credentials: [PROTECTED]; Authenticated: false; Details: null; Not granted any authorities
Am i missing some part of configuration here?
