Login authentication - Spring Boot Security, JDBC

Question

I'm looking for an easiest way to create Login form authentication, using spring boot and JDBC. I've created such code so far.

public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/", "/index").permitAll()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("/")
                .defaultSuccessUrl("/new", true)
                .permitAll()
                .and()
            .logout()
                .permitAll();
    }
    @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers("/css/**");
        web.ignoring().antMatchers("/images/**");
    }
    
    @Bean
    @Override
    public UserDetailsService userDetailsService() {
        UserDetails user =
             User.withDefaultPasswordEncoder()
                .username("user")
                .password("password")
                .roles("USER")
                .build();

        return new InMemoryUserDetailsManager(user);
    }
}

Now I need to get user's data from Oracle database and make login form. Does anyone can give me some tips? I've seen many projects on the internet, but it's really hard to copy them.
