here I am creating separate links for login as an admin/user. how to add a feature of a single login page that redirects to the next page according to the credential entered for ex: if user1 is an admin if his credentials are entered he will be redirected to the admin page and vise-versa for a user login

here is my spring security config code :-

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.dao.DaoAuthenticationProvider;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Bean
    public UserDetailsService getUserDetailService() {
        return new UserDetailsServiceImpl();
    }

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

    @Bean
    public DaoAuthenticationProvider authenticationProvider() {
        DaoAuthenticationProvider daoAuthenticationProvider = new DaoAuthenticationProvider();
        daoAuthenticationProvider.setUserDetailsService(this.getUserDetailService());
        daoAuthenticationProvider.setPasswordEncoder(passwordEncoder());

        return daoAuthenticationProvider;
    }

//  authentication - configure method

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

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().antMatchers("/show-menu-list-admin").hasRole("ADMIN")
                .antMatchers("/show-menu-list-customer").hasRole("USER").and().formLogin().and().csrf().disable();
    }

}
