Make one exending UserDetailsService, implement loadUserByUsername, and use it by:

public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

  protected void configure(HttpSecurity http) throws Exception {
     .and().rememberMe().tokenRepository(persistentTokenRepository()).userDetailsService(userDetailsService).key(TOKEN_KEY).tokenValiditySeconds((int) TimeUnit.DAYS.toSeconds(365));
